----------------------------------------------------------------------

(1)	What is OS/2?

OS/2 is an advanced operating system for PCs and PS/2s with an 80286 
processor or better.  It was codeveloped by Microsoft and IBM and 
envisioned as the successor to DOS.

It was designed from the ground up with preemptive multitasking and 
multithreading in mind.  It also protects applications from one another 
(a single misbehaved program will not typically disrupt the entire 
system), supports multimegabytes of physical RAM, and supplies virtual 
memory to applications as requested, breaking DOS's 640K barrier.

As shipped, it does not support multiuser operation, although third 
parties have grafted multiuser capabilities onto the base operating 
system.  Remote-OS (The Software Lifeline, 407-994-4466), OS2YOU 
(shareware; see Question 9), Citrix (Citrix Systems, 305-755-0559), and 
PolyMod2 (MemSoft) are four such products.

------------------------------

(2)	What are the differences between versions?

IBM OS/2 Version 2.0 (CSD Level 02000, see Question 24) will run only on 
machines with an 80386SX processor or better.  IBM is (now) developing 
OS/2 (and its Intel and non-Intel-based successors) independently but is 
involving third party PC manufacturers in its testing.  Improvements 
include the ability to preemptively multitask DOS, Windows 2.x, and 
Windows 3.0 (real and standard mode) applications (without purchasing 
any of these environments) in separate, robust, protected sessions; an 
object-oriented Workplace Shell (WPS); a multiple operating system boot 
mechanism; new 32-bit programming interfaces; support for more than 16 
MB of physical RAM (on systems with appropriate BIOS support); and more 
third party device drivers.  It also provides EMS 4.0 and XMS 2.0/DPMI 
0.9 (expanded and extended memory) services to DOS and Windows 
applications.  OS/2 1.x applications, unmodified, still run under OS/2 
2.0.

IBM OS/2 Version 1.3 is the last release of OS/2 to operate on PCs with 
80286 CPUs.  This version introduced built-in Adobe Type Manager (ATM), 
providing scalable typefaces for screen and printer.  Procedures 
Language/2 (a.k.a. REXX), a powerful batch-oriented programming 
language, became a part of Standard Edition with this release.  (A few 
OEMs are shipping Microsoft OS/2 Version 1.3, but Microsoft has all but 
abandoned OS/2 development.)

OS/2 Version 1.2 was the first to incorporate the High Performance File 
System (HPFS).  With this release IBM OS/2 added a dual boot mechanism 
and IBM Extended Edition introduced REXX.

OS/2 Version 1.1 was the first to include the Presentation Manager (PM) 
GUI/API, now an integral part of the operating system.  Microsoft OEM 
versions added a dual boot mechanism with this release.

OS/2 Version 1.0, introduced in 1987, was the first release of OS/2.  
Task switching was accomplished through a character-based shell and 
limited DOS compatibility was provided.

------------------------------

(3)	What is Extended Services?

Prior to Version 2.0, IBM offered two separate packages with each 
release of OS/2: Standard Edition and Extended Edition.  Extended 
Edition included extra, bundled software products: the Communications 
Manager (for communication with IBM mainframes, minicomputers, and other 
hosts), Database Manager (a full, network aware, relational database), 
and LAN Requester.

IBM has now unbundled the Extended Edition features, dropped LAN 
Requester from the package (now available separately, with IBM's LAN 
Server), updated it for OS/2 2.0, and renamed it Extended Services 1.0.  
ES, by itself, no longer includes the base operating system as Extended 
Edition once did.

This new arrangement makes it easier to update the base operating system 
with CSDs (see Question 24).  And now ES 1.0 will run under OS/2 1.3 
Standard Edition as well as OS/2 2.0.  Also, ES 1.0, like OS/2 2.0 
itself, is designed to operate on both IBM and non-IBM systems (see 
Question 7).

------------------------------

(4)	How good is OS/2 2.0's DOS and Windows compatibility?

OS/2 1.x justifiably earned a reputation for poor DOS compatibility.  
Since it was hampered by the 80286, it could not run more than one DOS 
application at a time.

The situation has changed dramatically with OS/2 2.0.  Version 2.0 
preemptively multitasks DOS and Windows (real and standard mode) 
applications in separate, protected sessions, without purchasing either 
environment.

OS/2 2.0 provides a complete DOS emulation equivalent to DOS 5.0.  The 
operating system can provide each DOS application with up to 32 MB of 
EMS 4.0 (expanded memory), 16 MB of XMS 2.0 (extended memory), and/or 
512 MB of DPMI 0.9 (DOS Protected Mode Interface extended memory), all 
from its pool of physical and/or virtual memory (meaning you do not have 
to have as much RAM in your system as your applications request).  These 
limits are in addition to the up to 730K free conventional memory 
supplied to each DOS application, even after mouse and network drivers 
are loaded.  As in DOS 5.0, DOS code and device drivers may be loaded 
into high memory.  A 386 memory manager like QEMM or 386Max is not 
needed -- these features are provided by OS/2 2.0 directly.

The DOS emulation allows customization of device driver sets -- each DOS 
application shares a systemwide CONFIG.SYS and the equivalent of its own 
CONFIG.SYS.  Also, there is a systemwide AUTOEXEC.BAT file; batch 
commands particular to each DOS application can be invoked using 
separate, application-specific batch files.  And many DOS Settings are 
provided to fine tune each DOS/Windows application's behavior (e.g. 
IDLE_SENSITIVITY).  Most of the popular DOS/Windows applications on your 
hard disk will be migrated automatically when you install OS/2 2.0.

In addition, OS/2 2.0 will boot one or more specific versions of DOS in 
separate sessions, to assist in running particularly difficult 
applications (e.g. DOS networks).  So, for example, it is possible to 
multitask DOS 3.3, DOS 4.0, DOS 5.0, emulated DOS, and Desqview running 
atop DOS, all in separate sessions, either windowed or full screen, all 
with the same and/or separate device drivers, TSRs, environment 
variables, etc.  These boot images may be stored on a hard disk.  
Specific DOS session procedures are described in the online Command 
Reference (under VMDISK) and in the Installation Guide, Appendix E.

Standard graphics modes (generally up to the resolution of the desktop; 
see Question 11) are supported in DOS windows, as are selectable text 
mode fonts.  Cut/paste to/from windowed DOS applications is supported 
(to/from other DOS, OS/2, and Windows applications), including graphics 
cut/paste.  Theoretically, OS/2 2.0 will run up to 240 simultaneous 
DOS/Windows sessions; the practical maximum depends on system resources.

OS/2 2.0 will, in fact, run virtually all DOS applications in existence, 
including notorious ones such as Microsoft Flight Simulator, Wing 
Commander, Maple, MatLab (Version 3.5k or later), and others.  Those 
that do not run generally fall into the following categories:

(a)  Programs that use Virtual Control Program Interface (VCPI) memory 
extenders or other extenders which require direct access to the 80386 
control registers.  Since such applications are also all but 
incompatible with Windows, most vendors have program updates for DPMI 
compatibility;

(b)  Applications which attempt to directly address the physical sectors 
of an OS/2 managed nonremoveable hard disk drive.  Such programs include 
UnErase in Norton Utilities, for example.  Fortunately OS/2 2.0 has a 
built-in UnDelete feature which is more robust than Norton's approach.  
(Consult the online Command Reference for information on how to enable 
UNDELETE);

(c)  Timing sensitive DOS applications.  Certain DOS programs that 
generate digitized sound through the PC's internal speaker may have 
distorted sound.  High speed, real time data collection may be 
compromised.  These problems can often be minimized or even eliminated 
using OS/2 2.0's DOS Settings.

(d)  Certain DOS programming debuggers.  DOS applications running under 
OS/2 2.0 are not permitted to access the debug registers DR0-DR7 from a 
DOS session.  Also, DOS debuggers will not be able to set hardware 
breakpoints, and all read/write operations to debug registers in virtual 
8086 mode will be ignored.

Generally DOS backup programs will work under OS/2 2.0, but they may not 
capture some of the OS/2 data (especially extended attributes) on the 
hard disk without the assistance of utilities such as EABK201 (available 
from shareware/freeware sources; see Question 9).  OS/2 backup tools are 
available, notably IBM's PMTape and PS2Tape (for IBM and Irwin tape 
systems), Sytos Plus (Sytron, 508-898-0100), EZTape (Irwin, 313-930-
9000), Intelligent Backup (Sterling, 916-635-5535), FileSafe (Mountain, 
408-438-2665), KeepTrack Plus (Finot, 800-748-6480), NovaBack (NovaStor, 
818-707-9900), and MaynStream (Maynard, 407-263-3500).  The OS/2 BACKUP 
utility is best used from an OS/2 diskette boot (see Question 13).  DOS-
based disk caching software is not required since OS/2 includes a built-
in, highly configurable, efficient disk cache.

DOS programs running under OS/2 2.0 are extremely fast.  A single DOS 
application (no other applications open) running full screen under OS/2 
2.0 typically achieves 95-97% of the performance it would have under 
native DOS.  If the DOS application performs any disk I/O it can 
actually operate faster than it would if running under native DOS.  It 
is not unheard of for disk intensive DOS applications to run twice or 
even three times as fast under OS/2 2.0.

If pure DOS is absolutely required, OS/2 2.0 includes a utility called 
the Boot Manager.  The Boot Manager can provide a listing of all the 
operating systems available on the system and will allow selection of 
any one at startup, with a default after timeout.  The OS/2 1.x DualBoot 
method is still available as well.  Consult the Installation Guide for 
instructions on how to configure your system to use Boot Manager or 
DualBoot.  Note that OS/2 2.0 need not be installed on Drive C -- it can 
reside on other volumes.

Compatibility with Windows, a popular DOS extender, is provided by Win-
OS/2, an environment based on Microsoft's Windows source code.  It runs 
Windows 2.x and 3.0 real mode and standard mode applications under OS/2 
2.0, either on a full screen Windows desktop (with the familiar Program 
Manager and one or more Windows applications) or "seamlessly," alongside 
OS/2 applications on the WPS desktop.  "Seamless" operation is available 
in VGA resolution with OS/2 2.0 as it ships; see Question 11 for 
information on third party drivers.

CVTICO or ICON, both available from shareware/freeware sources (see 
Question 9), will convert Windows icons for use by the OS/2 Icon Editor 
and/or OS/2-specific programs.  (No conversion is necessary if the icons 
are to be used with Windows programs running under OS/2 2.0.)

OS/2 2.0 directly provides Windows enhanced mode features save one: 
services included in WINMEM32.DLL.  Windows applications which utilize 
this DLL (e.g. Mathematica 2.0, Omnipage Professional 1.0) will not run 
under OS/2 2.0.  Fortunately the number of WINMEM32 applications is few, 
and apparently the vendors of such applications will be shipping OS/2 
2.0 compatible updates.

Windows applications are well integrated into the overall OS/2 WPS 
environment with DDE and Clipboard hooks, and OLE 1.0 is supported among 
Windows applications.  Adobe Type Manager for Win-OS/2 comes with OS/2 
2.0 (see Question 25).  Windows screen (for a full screen desktop) and 
printer device drivers will work under Win-OS/2.  Such notorious Windows 
applications as Word for Windows, Norton Desktop (save portions 
described above), Toolbook, and screen savers such as After Dark work 
fine under Win-OS/2.  Even the Windows Multimedia Extensions (and 
programs which utilize them) operate under Win-OS/2.  (For information 
on Multimedia Presentation Manager/2, the OS/2 2.0 multimedia 
extensions, call 800-426-9402 ext. 150.)

Win-OS/2 departs from Microsoft Windows in that it allows more than one 
Windows desktop and can preemptively (rather than cooperatively) 
multitask Windows applications in separate, robust, protected sessions.  
Also, while the enhancements incorporated into Windows 3.1 are 
functionally incorporated into Win-OS/2, Win-OS/2 is not technically 
Windows 3.1 compatible.  IBM has demonstrated 3.1-level Win-OS/2, and it 
is widely rumored that a free 3.1-level update will be available this 
fall.  Aside from the Windows 3.1 applets there are no Windows 3.1-
specific applications available.  (Win-OS/2 will run the Windows 3.0 
applets, but it does not include them.  Instead, true OS/2 2.0 
spreadsheet, database, communications, time planning/scheduling, and 
other applets are provided.)

Some Windows applications require OLE DLLs or custom settings in 
WIN.INI.  If such a Windows application has been installed under the DOS 
version of Windows, Win-OS/2 may not be able to find the appropriate 
files or configuration.  Try reinstalling the Windows application under 
Win-OS/2.

------------------------------

(5)	Where can I buy OS/2?

IBM OS/2 Version 2.0 is available from most software dealers (including 
Elek-Tek, 708-677-7660; and Corporate Software, 800-677-4000) and 
directly from IBM (800-3-IBM-OS2, 800-465-1234 in Canada).  In the U.K. 
call the OS/2 User Group (0285-655888) to order.  OS/2 2.0 on 3.5 inch 
diskettes is part no. 84F7586.  For 5.25 inch diskettes, 10G2991.  Media 
are high density.  For compact disc, 10G2992.  IBM OS/2 Version 1.3 is 
still available and may be ordered through many IBM dealers.

IBM is trying to make OS/2 2.0 available everywhere DOS is purchased.  
If your dealer does not stock OS/2 2.0, take your business elsewhere 
(and explain why).  IBM also has plans to bundle OS/2 2.0 with new PS/1, 
PS/2, and non-IBM systems.

Microsoft versions of OS/2 1.x are available only through OEMs (e.g. 
Compaq, Dell) or by purchasing Microsoft's LAN Manager 2.1 or SQL Server 
products.  Microsoft has all but ceased OS/2 development, working 
instead on Windows and the future, high-end NT (formerly OS/2 3.0).

------------------------------

(6)	How much does OS/2 2.0 cost?

IBM OS/2 2.0 retails for $195.  However, in the U.S. introductory 
pricing is available through October 31, 1992, by calling IBM's order 
line (800-3-IBM-OS2).  Upgrades are $79 from any version of Windows, $99 
from any version of DOS, and $149 without an upgrade.  (Call for details 
on upgrades from OS/2 1.x.)  Similar promotions are in effect in Canada 
and other countries.  Special pricing is available for multiple OS/2 
licenses.  Educational discounts are available but may not apply to the 
introductory prices.  (IBM's educational inquiries line in the U.S. is 
800-222-7257.)

IBM offers two money back guarantees in the U.S.: a 30-day, no questions 
asked, money back guarantee, and a 90-day compatibility guarantee (see 
Question 7).

------------------------------

(7)	What hardware do I need to run IBM OS/2 2.0?  Do I need a PS/2?

You need any PC compatible, PS/1, or PS/2 with at least an 80386SX CPU, 
4 MB (6 MB or more strongly recommended) of RAM, a 60 MB or larger hard 
disk (with 15-30 MB free), a supported video adapter (CGA, EGA, VGA, 
8514/A, XGA, or third party driver) with appropriate display, and a high 
density 3.5 or 5.25 inch floppy drive for installation.  A mouse or 
other pointing device is strongly recommended.  Allow extra RAM and hard 
disk space for OS/2-based networking, ES, and/or extra system loads 
(i.e. an extraordinary number of large applications running 
simultaneously).  When calculating hard disk space requirements, 
subtract space occupied by files already on the hard disk which are 
functionally included in OS/2 2.0 and may be deleted, e.g. DOS, a 386 
memory manager, Windows, Adobe Type Manager with base typefaces, etc.

The WPS will not operate with the Monochrome Display Adapter or the 
Hercules Monochrome Graphics Adapter.  Usually the WPS will fail to work 
with monochrome EGA.  However, some EGA adapters (e.g. Paradise 
Monochrome EGA Card, ATI EGA Wonder) will emulate all color EGA modes on 
TTL monochrome monitors and, thus, will work with the WPS.

On (E)ISA bus machines, OS/2 specifically supports hard drive adapters 
which conform to the Western Digital chipset interface standard (i.e. 
nearly all MFM, RLL, IDE, and ESDI adapters) and Adaptec, Future Domain, 
and IBM SCSI adapters.  (True OS/2 2.0 drivers for some SCSI adapters, 
e.g. Trantor and Procom, are available directly from the adapter 
manufacturer.)  In addition, "generic" INT13 support is provided for all 
other hard disk adapters.  This "generic" support even embraces such 
devices as Iomega's Bernoulli and SyQuest's removeable media products 
(but for best results contact Iomega or SyQuest for an OS/2 2.0 driver).  
CD-ROM support is included as well.  At present the OS/2 CD-ROM driver 
does not work with all brands, but the DOS device drivers, when 
installed using a specific DOS session, will still provide CD-ROM 
services to DOS/Windows programs.  See Question 12 for information on 
printer and plotter support.

Version 2.0 is explicitly supported on PC compatibles.  IBM is offering 
a money back compatibility guarantee in the U.S.  Should OS/2 2.0 fail 
to work on your compatible within the first 90 days of use, and should 
IBM be unable to fix the problem, your purchase price will be refunded.  
To date over 220 non-IBM models have been tested in IBM's own labs.

------------------------------

(8)	What applications are available for OS/2?

In addition to the thousands of applications available for DOS and 
Windows, there are a couple thousand OS/2-specific applications 
representing almost every category imaginable.

The DOS/Windows applications with 16-bit OS/2-specific counterparts 
include Lotus 1-2-3, Freelance, Microsoft Word, Excel, Multiplan, Aldus 
Pagemaker, Ventura Publisher, Corel Draw, WordPerfect, DisplayWrite, 
DeScribe, Micrografx Designer, AutoCAD, Oracle, RBase, SAS, SPSS, 
HyperAccess/5, DynaComm, Pro-YAM, Borland Sidekick, Paradox, Wingz, 
Brief, QEdit, 4DOS, and many others.  In some cases DOS and OS/2 
versions ship together (e.g. Microsoft Word 5.5, Lotus 1-2-3 3.0, 
Wingz).

OS/2 2.0 provides an attractive, 32-bit, Workplace Shell environment for 
new applications; many do not have DOS/Windows predecessors.  This new 
class of 32-bit applications will include Lotus 1-2-3, Freelance, 
cc:Mail, Notes, AmiPro, WordPerfect 6.0, N/Joy, DeScribe, Publisher's 
Paintbrush, PFS:Works, CorelDraw, HyperAccess, BitFAX, FAX/PM, and many 
more.  Over 1200 new 32-bit OS/2 2.0 applications are slated for release 
in the next year.

OS/2-specific versions of popular utilities include ZIP/UNZIP, ARC, LH2, 
Zoo 2.1, many GNU tools, tens of different file finders, desktop clocks, 
calculators, and many more.  Programming languages include Assembler, 
C++, COBOL, Pascal, C, Fortran, BASIC, REXX (included with every copy of 
OS/2 2.0), Smalltalk, Modula-2, LISP, Forth, and still more, from 
vendors such as Borland, Jensen and Partners International, Watcom, 
Symantec (through its Zortech subsidiary), IBM, Microway, and many more.  
Two ports of the 32-bit GNU C 2.1 compiler (one including the GNU 
debugger, the other including C++) are available from shareware/freeware 
sources (see Question 9).  A Fortran to C translator, f2c, is also 
available.  (See the Programmer's Edition of this List for more 
information.)

The IBM NSC BBS (404-835-6600) provides an online product database of 
OS/2-specific software.  A directory of OS/2 applications, IBM document 
number G362-0029-02, is published by Graphics Plus (800-READ-OS2).  TINF 
is an applications directory (for use with the OS/2 VIEW facility) 
available from shareware/freeware sources listed below.

------------------------------

(9)	Where can I obtain OS/2 shareware and freeware?

Many BBSes, including Fernwood (203-483-0348), OS/2 Shareware BBS (703-
385-4325), Bay Area OS/2 BBS (510-657-7948), Gateway/2 (314-554-9313), 
and Greater Chicago Online (708-895-4042), hold large OS/2 libraries.  
The IBM NSC BBS has some shareware/freeware as well, along with CSDs 
(see Question 24) and the PS/2 Assistant (an invaluable resource for 
locating almost any sort of information on OS/2).  For information on 
IBM's new OS/2 BBS call 800-547-1283.  IBM Canada maintains several 
support BBSes (604-664-6466, 416-946-4255, and 514-938-3022 at 2400 bps; 
604-664-6464 and 416-946-4244 at 9600 bps).

The Usenet conference comp.binaries.os2 carries OS/2 software.  And 
several sites are available via anonymous ftp.  (No ftp?  Send a single 
line message with the word HELP to bitftp@pucc.bitnet or 
ftpmail@decwrl.dec.com to learn about ftp mail servers.)  They include 
(with Internet node numbers and subdirectories):

ftp-os2.nmsu.edu            128.123.35.151     pub/os2
mtsg.ubc.ca                 137.82.27.1        os2:

The last site should not be accessed weekdays from 8:00 a.m. to 5:30 
p.m. Pacific Time.  The ftp-os2.nmsu.edu and novell.com libraries are 
available on CD-ROM from Walnut Creek (510-947-5996).

Other sources include CompuServe ("GO IBMOS2") and an archive server 
(send a single line message with the word HELP to 
listserv@cc1.kuleuven.ac.be for more information, or use ftp).

------------------------------

(10)	I am having trouble installing OS/2 2.0.  What should I do?

First consult the Installation Guide and other materials accompanying 
OS/2 2.0.  Make sure your PC meets the system requirements in Question 
7.

And if the following instructions do not help, fall back on IBM's toll 
free technical support (800-237-5511 in the U.S.) and/or consult IBM's 
Tips and Techniques file, available from shareware/freeware sources (see 
Question 9).

Certain PC compatibles have difficulty accepting OS/2 2.0 (CSD level 
02000 only; see Question 24), particularly AT bus systems with RLL, MFM, 
ESDI, or certain SCSI adapters (e.g. AMI SCSI adapters).  The problem 
usually appears in the form of FDISK errors, extremely slow copying to 
the hard disk, or a whining/grating noise emanating from the hard disk.

IBM suggests a simple workaround.  First, DISKCOPY Diskette 1 of your 
OS/2 2.0 package.  Set aside your original Diskette 1 and use the copy 
from now on as if it were the original.  Using a text editor, modify the 
CONFIG.SYS file on Diskette 1 (the copy), replacing the line:
	BASEDEV=IBM1S506.ADD
with
	REM BASEDEV=IBM1S506.ADD.
Boot the Installation Diskette, and proceed through the installation 
procedure through the first few diskettes, then reinsert the 
Installation Diskette as directed.  Then after files have been copied 
from the Installation Diskette the system prompts you to remove the 
diskette and press ENTER to reboot.  Do so, but immediately reinsert the 
Installation Diskette as soon as the screen clears.  Follow instructions 
(insert Diskette 1 and press ENTER when prompted), then press ESC when 
prompted.  At the OS/2 command line, type:
	RENAME C:\OS2\IBM1S506.ADD IBM1S506.XXX
	COPY C:\OS2\IBMINT13.I13 C:\OS2\IBM1S506.ADD
replacing C: with the appropriate drive if you are installing elsewhere.  
Remove Diskette 1, then press CTRL-ALT-DEL to reboot to finish 
installation.

The mouse selection menu provided when installing is a bit confusing.  
Usually you should accept the default the system selects for you.  The 
Logitech Mouse selection should be chosen only if you have a Mouse 
Systems PC Mouse (or compatible, e.g. certain Genius models) or a 
Logitech C7 or C9 serial mouse.  (If you have another Logitech pointing 
device, it is likely Microsoft compatible when powered up, so select the 
appropriate Microsoft driver, e.g. "Serial Pointing Device.")  If you 
are using a Logitech C7 or C9 serial mouse and have been using native 
DOS, be sure to issue the command MOUSE PC (or MOUSE 2 PC if your mouse 
is attached to COM2) before booting into or installing OS/2.  
Alternatively, turn off the system (to reset the mouse) before booting 
or installing OS/2.

Some PCs have trouble printing under OS/2 2.0.  This problem can often 
be traced to an interrupt conflict, or a substandard cable or printer 
adapter.  LPT1 uses IRQ 7, and LPT2, if installed, uses IRQ 5.  
Interrupts should not be shared on AT bus machines.  The SoundBlaster 
card, for example, comes set to IRQ 7.  Reset it to an unused interrupt.

Make sure adapters with onboard ROMs are not conflicting with other 
adapters.  For example, many SuperVGA adapters use large chunks of upper 
memory, and many hard disk adapters have onboard ROMs which can be 
mapped into this area as well.  Adapters must cooperate in their use of 
memory and interrupts and must not share address space or interrupts.  
Check your product manuals for more help.

Be sure adequate free disk space is available before installing, 
including space for a swap file.  Drives compressed using Stacker or 
similar utilities should be uncompressed before installing (unless 
access to these drives is not needed).  OS/2 2.0 is not presently 
compatible with Stacker or similar DOS utilities.  However, an OS/2 2.0 
version of Stacker is forthcoming, and Proportional Software's DCF/2, a 
Stacker-like utility, is now available by calling 800-666-4672.

Do not select HPFS when installing if your machine has 6 MB of RAM or 
less.  Doing so will likely result in diminished performance.  Change 
the IFS=...HPFS line in your CONFIG.SYS to REM IFS=... if necessary.

Automatic migration of your DOS CONFIG.SYS and AUTOEXEC.BAT files is not 
recommended.  If you have Windows 3.1 installed on your system do not 
migrate your Windows desktop.

Be sure your CMOS setup parameters are set correctly, especially those 
relating to floppy drives.  Disable all shadow RAM for best performance 
(unless compatibility problems arise).  RAM should be given sufficient 
wait states and precharge cycles.  The AT bus should run at 8 MHz.

If you are using the IBMINT13.I13 driver to access an MFM, RLL, or ESDI 
hard drive, and the hard drive has more than 1024 cylinders, be certain 
your hard disk adapter's sector translation mode is enabled.

Some Quantum LPS105AT IDE hard disks require a free ROM update (Version 
2.6) from the manufacturer to work with OS/2.

If your AMI keyboard BIOS is below Revision F you may need an update.  
Contact Washburn & Assoc. (716-248-3627).

Some keyboards have DIP switches.  Check to make sure the switches are 
set correctly.  For example, if the keyboard is attached to a system 
with an AT bus it should typically be switched to "AT" mode.

"Autoswitching" on non-IBM EGA adapters should be disabled (usually with 
a DIP switch or jumper setting).  In rare cases it may be necessary to 
switch third party VGA/SuperVGA adapters into 8-bit mode and/or disable 
"autosense."  See Question 11 for more SuperVGA advice.

OS/2 is particularly sensitive to bad RAM or cache memory (often 
reflected in TRAP 2 error messages).  Use a thorough RAM testing 
utility, and try not to mix 9 chip and 3 chip SIMMs/SIPPs.

The HP DeskJet and DeskJet Plus printers work, without loss of 
functionality, using the Epson EPL-6000, Epson EPL-7000, or LaserJet 
Classic driver (with Fast System Fonts disabled).  As of this writing a 
DeskJet 500C color driver (for OS/2-specific programs) is not yet 
available.

Allow several minutes for OS/2 2.0 to build your desktop (and display 
icons) at the end of installation -- take the Tutorial offered to you in 
the meantime.  Select Shutdown and reboot once after installation 
completes to ensure that DOS/Windows applications will operate properly.  
Avail yourself of the "Start Here" icon, the other online help, and the 
README file located in the root directory.  They will help in getting 
started with the WPS and in properly configuring your system.

When installing over a beta version of OS/2 (except OS/2 2.0 level 
6.177H, the Limited Availability release) be sure to reformat.

To install the OS/2 2.0 DOS/Windows upgrade DOS or OS/2 must already 
reside on the hard disk.  If Diskette 1 is not write protected then the 
installation program will record a file indicating that upgrade terms 
have been satisfied and, in the future, will not require DOS or OS/2 on 
the hard disk to install.

OS/2 uses the same diskette format as DOS, so use DISKCOPY to backup the 
installation diskettes and verify that none have been corrupted.

Owners of IBM PS/2s should make sure that any applicable ECAs 
(engineering changes) have been performed.

Try disconnecting any tape backup device if "Cannot find COUNTRY.SYS" 
messages are encountered when booting OS/2.

Contact IBM for a fix to install OS/2 2.0 on certain Zeos notebooks.

An Always IN-2000 SCSI adapter with BIOS version 3.06A or 3.20 requires 
an updated BIOS from the manufacturer.  A companion 8-pin serial PROM 
chip may also need to be updated.  Contact Always at 818-597-9595.

------------------------------

(11)	Will OS/2 2.0 work with my SuperVGA adapter?

If you have a SuperVGA adapter, OS/2 2.0 should initially be installed 
using the standard VGA driver.  Then consult the README file OS/2 copies 
to your root directory for more information on SuperVGA support.

OS/2 2.0 comes with basic mode switching capabilities to handle 
applications which utilize SuperVGA modes.  If OS/2 2.0 detects a 
SuperVGA adapter it will list two SuperVGA support files, VSVGA.SYS and 
BVHSVGA.DLL, in your CONFIG.SYS file.  (A replacement VSVGA.SYS file, 
dated April 20, 1992, or later, fixes Tseng 4000 and TRAP E problems.  A 
replacement BVHSVGA.DLL file, dated April 21, 1992, or later, fixes 
installation problems involving Western Digital/Paradise PVGA1D chipset 
adapters.  Both are available from shareware/freeware sources; see 
Question 9.)

To enable this mode switching support you must start a DOS full screen 
session, issue the command SVGA ON, EXIT, Shutdown, and reboot.  (In the 
same DOS full screen session and prior to SVGA ON you may run utilities 
which customize refresh rates.  The new refresh rates will take effect 
after you reboot.  You may also wish to run such a utility from 
AUTOEXEC.BAT.)  SVGA ON creates a text file called \OS2\SVGADATA.PMI 
which describes your SuperVGA adapter to the system.  Then you may 
install high resolution drivers.

Aside from DOS applications (which may require their own drivers), OS/2 
2.0 requires up to three high resolution support files:

\OS2\DLL\DISPLAY.DLL                 Workplace Shell display driver
\OS2\MDOS\WINOS2\SYSTEM\VGA.DRV      Win-OS/2 full screen driver
\OS2\MDOS\WINOS2\SYSTEM\SWINVGA.DRV  Win-OS/2 "seamless" driver

You may replace any one of these individually for high resolution 
operation in each given mode, but be sure to keep a backup copy of the 
original file(s).  The "seamless" Win-OS/2 and WPS desktop driver files 
must match (in terms of resolution and number of colors) if you wish to 
run Windows programs "seamlessly."  Any suitable Windows SuperVGA driver 
will work as a Win-OS/2 full screen driver, but be sure to use the 
EXPAND utility (as described in README) when installing.

OS/2 1.3 SuperVGA drivers often serve, with some limitations, as WPS 
desktop drivers.  Use the command DDINSTAL to replace DISPLAY.DLL.  
Setting IOPL=YES in CONFIG.SYS may be required with a SuperVGA adapter.

As of this writing Trident, Orchid and STB (Tseng 4000 chipset), and ATI 
(due to third party efforts) are the only SuperVGA vendors with OS/2 2.0 
high resolution drivers, although several other manufacturers have 
promised drivers.  When available they will be provided through 
shareware/freeware sources (see Question 9).

Some SuperVGA adapters cause problems with DOS/Win-OS/2 sessions.  Try 
turning VIDEO_ROM_EMULATION off, HW_ROM_TO_RAM on, and/or DOS_RMSIZE to 
624 in DOS Settings.

If you have an ATI Ultra, Vantage, or other 8514/A hardware compatible 
adapter, install OS/2 using the 8514/A driver.  For the Graphics Ultra 
and Graphics Vantage change the line DEVICE=...VVGA.SYS to 
DEVICE=...VSVGA.SYS in CONFIG.SYS; Shutdown and reboot.

IBM was unable to test all SuperVGA adapters, so if you are experiencing 
problems report them through IBM's toll free support (800-237-5511 in 
the U.S.) or to the adapter manufacturer.

If SuperVGA continues to cause problems the stock VGA driver may be used 
(preventing DOS/Windows applications from using SuperVGA modes, 
however).  In CONFIG.SYS change DEVICE=...VSVGA.SYS to ...VVGA.SYS and 
SET VIO_VGA...(BVHVGA,BVHSVGA) to ...(BVHVGA).

OS/2 2.0's installation program has difficulty with certain Oak video 
adapters.  Temporarily replace the video adapter to install OS/2, or 
contact IBM for a patch.

------------------------------

(12)	Will OS/2 2.0 work with my printer?

OS/2 2.0 includes support for Hewlett-Packard LaserJets, DeskJets (see 
Question 10), and PaintJets; IBM ExecJets, Proprinters, Quickwriters, 
Quietwriters, Pageprinters, and Laserprinters; Epson dot matrix and 
laser printers; Postscript devices; and other printers (e.g. Panasonic) 
compatible with these families.  A variety of IBM and HP plotters is 
also supported.

DOS/Windows printer drivers continue to work for DOS/Windows 
applications.  OS/2 2.0 includes a large assortment of Windows printer 
drivers for Win-OS/2.  If necessary install Windows printer drivers 
using the Win-OS/2 Control Panel.  OS/2 2.0 and OS/2 1.3 printer drivers 
are interchangeable, by and large.

If your printer is not compatible with one of the drivers supplied with 
OS/2, check with the printer manufacturer first then with 
shareware/freeware sources (see Question 9).  If you own an IBM printer, 
check with the Lexmark BBS (606-232-5653).

------------------------------

(13)	How do I access HPFS partitions on my hard drive without booting
	from the hard drive?  I'm getting error messages now -- how do I 
	"repair" my hard disk?

With IBM OS/2 2.0, insert the Installation Diskette, Shutdown (if 
necessary), and reboot.  When prompted insert Diskette 1 and press 
ENTER.  When prompted, press ESC.  You will be given an OS/2 command 
line prompt.  From there you can make necessary changes to your hard 
disk -- an OS/2 character mode text editor on diskette is handy for such 
changes.  (Make sure you backup CONFIG.SYS before making any changes so 
that you can easily revert to the old version should things go wrong.)

You may use this diskette boot method to run CHKDSK on your FAT or HPFS 
partitions.  After you reach the command line, insert Diskette 2.  Do 
not log to another drive.  Type CHKDSK X: /F to repair most kinds of 
damage to your hard disk, replacing X with the appropriate drive letter.  
(If you are checking a HPFS disk, use /F:3.)  OS/2 CHKDSK will also 
remark your hard disk as accessible, if possible, should OS/2 "lock it 
out" for some reason.

"Errors" may be reported by CHKDSK if OS/2 was booted from the hard 
disk.  These "errors" are normal.  Since the hard drive is in use by 
OS/2 itself (and files are open) CHKDSK is unable to accurately report 
errors.

The best way to avoid the need to perform CHKDSK is to always select 
Refresh then Shutdown.  Click on the Workplace Shell desktop background 
using mouse button two to bring up the appropriate menu.  Also, avoid 
manipulating OS/2-related files when using native DOS.  Finally, enable 
autochecking for all your hard disk volumes.  For HPFS volumes use the 
/AUTOCHECK parameter in the IFS=...HPFS line in your CONFIG.SYS.  For 
FAT volumes use the AC parameter in the DISKCACHE line of your 
CONFIG.SYS.  See the online Command Reference for details.

------------------------------

(14)	I can't install OS/2 2.0 from Drive B.  What's wrong?

IBM OS/2 2.0 can only be installed from Drive A, like DOS (unless your 
BIOS supports booting from Drive B), or across a network (contact IBM 
for more information on network installation procedures).  If you have 
the wrong disk size go back to your dealer and obtain the correct media.  
Otherwise you could go inside your machine and swap floppy drive cable 
connectors, use your system's setup utility to set the new CMOS 
parameters, and then install OS/2 from the "new" Drive A.  Sometimes the 
floppy drive cable connectors will not be the same.  If so you can 
obtain an adapter plug.

You may also use IBM's new twin "bootstrap" diskette images, available 
from shareware/freeware sources (see Question 9), to boot from a 5.25 
inch Drive A and install using 3.5 inch OS/2 diskettes inserted into 
Drive B.

------------------------------

(15)	Is there a Norton Utilities for OS/2?

Not yet, although Norton Desktop, Norton Utilities, and Norton Commander 
all work under OS/2 2.0's DOS/Windows sessions (with limitations noted 
in Question 4).  But the GammaTech Utilities should fill the role.  
Contact their publisher at 405-359-1219.  Note that OS/2 2.0 has a 
built-in UnDelete utility (see the README file or online help), and HPFS 
is resistant to fragmentation (see Question 18).

------------------------------

(16)	Sometimes OS/2 2.0 will freeze when I run an application.  What do
	I do?

Before rebooting with CTRL-ALT-DEL, try CTRL-ESC.  Do not hit additional 
keys, do not move the mouse.  Wait up to a minute.  In most cases the 
Window List or an error message will pop up.  If you wish you may close 
the offending application at that point.  (Try ALT-ESC if you have 
disabled CTRL-ESC in that application's DOS Settings.)

If the system is badly disabled, sometimes pressing CTRL-ALT-NUMLOCK 
twice will result in a prompt to create a dump diskette.  You may do so 
(the online Command Reference describes dump diskettes) or at that point 
you may reboot with CTRL-ALT-DEL.

To prevent applications from automatically restarting, see Question 29.  
To restore the desktop to "factory defaults," use ALT-F1 when OS/2 2.0 
starts.  See the README file in your OS/2 root directory for details.

------------------------------

(17)	How can I get answers to my OS/2 questions?

If your question is not answered in this List, post a note to the 
appropriate Usenet conference: comp.os.os2.apps carries discussions 
related to finding or using any application running under OS/2, 
comp.os.os2.networking looks at networking issues, comp.os.os2.advocacy 
deals with opinions and speculation, comp.os.os2.programmer addresses 
anything related to OS/2 programming, and comp.os.os2.misc is for any 
other OS/2-related discussion.  These groups are watched closely by many 
OS/2 experts from IBM.  Also, comp.lang.rexx discusses REXX programming.  
A LISTSERVer distributes its own OS/2 conference by mail; send a single 
line message with the word HELP to listserv@cc1.kuleuven.ac.be for full 
instructions; or send the same message to listserv@frors12.circe.fr for 
information on an unedited mailing list.

Your local FidoNet BBS may carry OS/2 echo conferences.  If not, ask 
your system operator to get ahold of them.  CompuServe ("GO IBMOS2") and 
Prodigy are also excellent resources.

The IBM NSC BBS was established as a support forum.  That BBS's message 
areas, product database, and PS/2 Assistant file(s) are invaluable 
resources.  Information on the new OS/2 BBS is included in the OS/2 2.0 
package.  In the U.S. IBM has toll free technical support (800-237-
5511), an OS/2 Hotline (general information, orders, upgrades, 800-3-
IBM-OS2), the HelpWare Center (800-PS2-2227), a software order line 
(800-IBM-CALL), an automated FAX information service (800-IBM-4FAX), and 
an educational inquiries line (800-222-7257).  In Canada call IBM 
Personal Systems Software at 800-465-1234.  OS/2 2.0 developers should 
contact the IBM Developer Assistance Program at 407-982-6408.  IBM 
offers classes worldwide to help in using and programming OS/2 2.0; call 
your local IBM branch office (or the OS/2 Hotline) for more information.

OS/2 has its own magazines as well.  To subscribe to OS/2 Developer 
Magazine call 800-WANT-OS2.  For information on OS/2 Monthly send mail 
to JDS Publishing at 72550.2440@compuserve.com or call 800-365-2642.  To 
subscribe to Inside OS/2 write The Cobb Group, P.O. Box 35160,

and many titles from Van Nostrand-Reinhold (800-296-2665).  (To order 
IBM publications phone your local IBM office and ask for the Librarian 
or call 800-7654-IBM.)

Any of the regular DOS or Windows resources (e.g. books, magazines, 
shareware/freeware sources) will be useful since both environments come 
with OS/2 2.0.

------------------------------

(18)	Why should I use HPFS?  What does it offer me?  Does it work with
	DOS?

HPFS offers long file names (up to 254 characters including the path, 
greatly exceeding the "8 dot 3" limit in DOS's FAT file system), 
contiguous storage of extended attributes (without the EA DATA. SF file 
used by FAT), resistance to file fragmentation, improved media error 
handling, smaller cluster size, support for larger file storage devices 
(up to 512 GB), and speedier disk operation, particularly on large hard 
disks, on systems with more than 6 MB of RAM.  HPFS is not case 
sensitive, although it does preserve case in file names.

However, HPFS is not currently supported on removeable media, although 
some programs (e.g. BACKUP) preserve long file names on such FAT disks.  
Also, native mode DOS cannot access a HPFS partition.  However, 
DOS/Windows sessions running under OS/2 can use all files that conform 
to the "8 dot 3" naming conventions, even if they are stored on HPFS 
volumes.

------------------------------

(19)	I'm a Unix wizard.  How do I make OS/2 resemble Unix?

A great number of GNU and Unix utilities have been ported to OS/2 native 
mode and are available from shareware/freeware sources (see Question 9).  
A uucp package, UUPC/Extended, is available via anonymous ftp from 
sun.soe.clarkson.edu, directory pub/uupc; mail help@kew.com with 
questions.

In addition, the Hamilton C Shell is available from Hamilton Labs (508-
358-5715 or mail 3890321@mcimail.com).  The Thompson Toolkit, a Bourne-
like shell, is published by Thompson Automation (206-224-1639).  
Thompson offers a version of awk as well.  MKS (519-884-2251 or mail 
pat@mks.com) publishes a number of standard Unix utilities for OS/2.  
Argosoft (510-795-7921) publishes ARGO/UX, a BSD 4.3 Unix compatible 
environment.  For OS/2-specific X Windows server support, IBM provides 
an optional package available with its TCP/IP 1.2.1 for OS/2.  The 
TCP/IP 1.2.1 base package includes a news reader as a sample 
application.

DOS and Windows based utilities and aids still work fine under OS/2 2.0.

------------------------------

(20)	I prefer Windows.  How do I make OS/2 2.0 resemble Windows (or
	OS/2 1.3)?

At first the Workplace Shell may seem strange and different.  Use it for 
a while and then decide.

If you still feel you want change how OS/2 2.0 works, follow the 
instructions beginning on p. 29 in the "Migrating to the OS/2 Workplace 
Shell" booklet.

------------------------------

(21)	I would like to set up an OS/2 BBS.  What is available?

OS/2 is an excellent environment for BBS operation (even using 
DOS/Windows software), including large multiline facilities.  Related 
software will enable FidoNet capabilities, gateways to Usenet/UUCP, 
nodelist processing, additional file transfer protocols, and more.

Five popular OS/2-specific BBSes are Maximus and Simplex (available from 
the shareware/freeware sources listed above), Omega Point/2 (BBS 404-
564-1961), Magnum (818-706-9800, BBS 818-706-9805), and Multi-Net (503-
883-8099, BBS 503-883-8197).

------------------------------

(22)	Can I use COM3 and COM4 in OS/2?

COM3 and COM4 are supported on PS/2s without any additional effort.  On 
(E)ISA machines, some additions are required to CONFIG.SYS.  Using a 
text editor, include "(port number, base address, interrupt number)" 
parameters next to the COM.SYS and VCOM.SYS filenames.  One example:
	DEVICE=C:\OS2\COM.SYS (3,3E8,5) (4,2E8,2)
	DEVICE=C:\OS2\MDOS\VCOM.SYS (3,3E8,5) (4,2E8,2)
Parameters for COM1 and COM2 need not be included (unless they are 
somehow nonstandard).  OS/2 must end up with sequentially numbered 
logical COM ports.  For example, if (physical) port two is not installed 
but port three or port four is installed start numbering using (2,...) 
in the DEVICE lines.  Note that IBM has released patched COM drivers 
which may be of some assistance.

Note that AT bus COM ports cannot be used at the same time if they share 
interrupts because of bus design limitations (cf. "Under the Hood: How 
Interrupts Work," Byte, February, 1992).  PolyCom, a replacement driver 
available from shareware/freeware sources (see Question 9), supports up 
to eight ports with the right hardware.

"Smart" (coprocessor controlled) multiport communication adapters should 
be used when installing more than four ports.  Such an adapter will work 
with OS/2 if the manufacturer has written an appropriate driver.  
Examples include IBM's ARTIC products, Digiboard (213-645-1082) and 
Stargate (800-782-7428) adapters.

------------------------------

(23)	How do I start a background process from the OS/2 command line?

Look up the START and DETACH commands in the online Command Reference.

------------------------------

(24)	What are CSDs, how do I tell which I have, and where do I get
	them?

CSDs are Corrective Service Diskettes, or bug fixes, periodically issued 
by IBM.  The OS/2 CSD level number may be obtained using the command 
SYSLEVEL from an OS/2 command line prompt.  CSDs are cumulative, i.e. 
only the most recent CSD is required to bring a system up from any 
previous CSD level.  However, CSDs only apply within a major version 
number.  For example, an upgrade, not a CSD, would bring OS/2 Version 
1.3 up to Version 2.0.  Note also that each national language (e.g. 
French, U.K. English) uses a distinct CSD.

CSDs may be ordered by anyone with an IBM customer number (usually large 
sites) directly from IBM Defect Support (800-237-5511).  OS/2 users 
without customer numbers should ask authorized IBM dealers to order CSDs 
from that source.  Many dealers do not know about this program, so be 
persistent.  CSDs may also be downloaded from the IBM NSC BBS, 
CompuServe ("GO IBMOS2"), or from other shareware/freeware sources (see 
Question 9).  And CSDs may be ordered through IBM's new OS/2 BBS.

The most recent OS/2 2.0 CSD level will be listed in this List and in 
the PS/2 Assistant files.

------------------------------

(25)	How do I add new Adobe Type Manager typefaces?

OS/2 2.0 comes with built-in Adobe Type Manager for OS/2 and Win-OS/2.  
A basic set of typefaces comes with OS/2 2.0 and is installed for use 
under OS/2's ATM.  To install these same typefaces for use under Win-
OS/2's ATM, go to the Win-OS/2 ATM Control Panel and install the 
typefaces from the last Printer Diskette.

Each typeface should come with three separate files with PFB, AFM, and 
PFM extensions.  To install a typeface for use under Win-OS/2, use the 
ATM Control Panel.  To install a typeface for use with OS/2-specific 
applications, select OS/2 System -> System Setup -> Font Palette -> Edit 
Font -> Add.

PFM files may converted to AFM files using the PFM2AFM utility, 
available from shareware/freeware sources (see Question 9).  For 
information on obtaining AFM files for Adobe commercial typefaces send a 
single line message with the word HELP to ps-file-server@adobe.com.

With the exception of the basic set of typefaces that comes with OS/2 
2.0, typeface files may be shared by OS/2 ATM and Win-OS/2 ATM.  To do 
so, install the typefaces using both the Font Palette and Win-OS/2 ATM 
Control Panel, specifying the target path each time (most conveniently 
\PSFONTS).

Note that IOPL=YES should appear in CONFIG.SYS; the modules WPPWNDRV, 
BVHSVGA, and PMATM are marked as requiring I/O privilege.

------------------------------

(26)	How do I tweak OS/2 2.0 for maximum performance?

For OS/2 overall, the parameters MAXWAIT, TIMESLICE, PRIORITY, 
PRIORITY_DISK_IO, PROTECTONLY, and cache settings (in the DISKCACHE, for 
FAT, or IFS, for HPFS, lines) can be tweaked.  These parameters are 
documented in the online Command Reference.  The swap file should be 
placed on the most used partition on the least used hard disk.  Use 
CONFIG.SYS's SWAPPATH line to control the swap file's location.

FAT partitions should be periodically defragmented.  A shareware 
defragmenter for DOS called DOG (Disk OrGanizer) works well.  (You can 
boot DOS from a floppy disk to run such a utility.)

For the Workplace Shell, drag shadows of most often used items to the 
desktop or folders closer to the "surface" -- opening folders takes 
time.  Drag shadows of programs you use often (e.g. the Win-OS/2 full 
screen Program Manager) to the Startup folder.  Disable animation (go to 
OS/2 System -> System Setup -> System -> Window).  Use the faster 
Details View when opening drive and folder objects; to set Details View 
as the default, open the settings notebook for the object, select the 
Menu tab, click on ~Open, then the Settings button, then select the 
Default Action.

Try reducing the number of on screen colors or dropping down in screen 
resolution to enhance speed.  Close (not just minimize; check the Window 
List) unnecessary objects and applications.  Consider adding more RAM.

For DOS programs, run full screen instead of windowed if speed is 
important.  In DOS Settings for each application: reduce conventional, 
XMS, DPMI, and EMS memory allocations to the bare minimum required for 
maximum performance; turn off VIDEO_RETRACE_EMULATION unless necessary; 
adjust IDLE_SENSITIVITY; turn off DOS_BACKGROUND_EXECUTION if not 
needed; change the HW_TIMER setting (particularly for games); enable 
VIDEO_FASTPASTE if possible; turn on HW_ROM_TO_RAM.  Communications 
programs should use hardware handshaking where possible (use OS/2's MODE 
COMx command if necessary), and a buffered UART can prove helpful.  (DOS 
programs running under OS/2 will not be aware of a buffered 16550AF 
UART.  OS/2 virtualizes the serial port and manages the buffer itself.)  
For faster printing set the DOS program's output port to LPTx.OS2 (where 
x is the printer port number) -- use a "print to file" option if 
necessary.  Disable any DOS print spoolers; rely on OS/2's spooler 
instead.  Increase CONFIG.SYS's PRINTMONBUFSIZE values.  Other, standard 
steps to enhance DOS performance (e.g. increasing BUFFERS in CONFIG.SYS) 
of course apply.

For Windows programs, run using a full screen desktop if speed is vital.  
The Win-OS/2 Full Screen icon set up by the installation program has 
poor Settings.  For better performance perform some of the same steps 
outlined in the preceding paragraph, including VIDEO_RETRACE_EMULATION 
off.  The same printer output advice also applies.  In addition, the 
Print Manager should be disabled (OS/2 provides a systemwide spooler).  
From the Win-OS/2 desktop close the Print Manager, uncheck the "Use 
Print Manager" box from the Win-OS/2 Control Panel -> Printers section, 
then, using a text editor, edit the \OS2\MDOS\WINOS2\SYSTEM.INI file, 
removing the ",!printman" entry from the MAVDMApps line.  (This last 
step will keep a warning dialog box from appearing each time you start 
the Win-OS/2 desktop.)  Consider disabling the Public setting in the 
Clipboard.  If available, set VIDEO_8514A_XGA_IOTRAP to off and 
VIDEO_SWITCH_NOTIFICATION to on (unless mouse control is lost).

(27)	What networking products are available for OS/2 2.0?

In addition to DOS/Windows products, OS/2-specific TCP/IP support is 
available from IBM (800-IBM-CALL), Essex Systems (508-532-5511), FTP 
Software (send mail to info@ftp.com), and others.  NetWare Requester for 
OS/2 is available from Novell (800-873-2831); NetWare Server has been 
demonstrated by IBM.  IBM offers both NetWare and LAN Server 2.0 (basic 
and advanced) with LAN Requesters.  Microsoft sells LAN Manager 2.1 
(which comes bundled with OS/2 1.3).  An OS/2 2.0 LAN Manager Requester, 
part no. 96F8359, is available from IBM.  A beta LAN Manager Requester 
written by Microsoft is available from shareware/freeware sources (see 
Question 9).  DEC sells Pathworks for OS/2.  A Banyan Vines OS/2 2.0 
requester is due shortly, and the current DOS requester works in a 
specific DOS session.

------------------------------

(28)	Should I worry about viruses when running OS/2 2.0?

At present there are no OS/2-specific viruses.  However, DOS/Windows 
viruses can conceivably infect an OS/2 2.0 system.  DOS/Windows 
antivirus tools are just as useful in preventing such infection.  Also, 
IBM has an antivirus package which runs under OS/2 directly (without 
DOS/Windows emulation), and others are on the way.

But OS/2 2.0 is likely to be much more resistant to viruses because of 
its design.  Viruses running in one virtual DOS/Windows session are 
likely to be confined to that session.  Low level disk access is 
curtailed under OS/2 2.0, thus preventing most virus infection at that 
level.  And when a DOS/Windows virus does trigger, it is far less likely 
to disrupt the entire system.

OS/2 2.0 is by no means virus proof -- no system is.  But it should 
prove more resistant to virus infection.

------------------------------

(29)	Are there any clever tricks that apply to OS/2 2.0?

If you have installed the optional bitmaps, try clicking on the WPS 
desktop background once with mouse button one and pressing CTRL-ALT-
SHIFT-O.

If you have a color monitor, try editing your CONFIG.SYS file so that
	SET PROMPT=$e[32;40m$e[1m[$P]$e[0m
to obtain a more colorful OS/2 command line prompt.  You can do the same 
for your DOS sessions if you edit PROMPT in AUTOEXEC.BAT, assuming you 
have ANSI.SYS loaded.

To force DIR to display your directories in alphabetical order, with the 
subdirectories listed first, edit CONFIG.SYS so that
	SET DIRCMD=/O:GN
and, if you wish the same for your DOS command line sessions, use DOSKEY 
(see the online Command Reference) in AUTOEXEC.BAT.  DOSKEY also enables 
command history.  (Shutdown and reboot for changes to CONFIG.SYS to take 
effect.)

Hold down SHIFT while resizing text windows to make size changes 
permanent.

While running a DOS graphics program in a window, use the graphics cut 
and paste feature to clip a picture and paste it into the Icon Editor.  
You can then quickly and easily create custom icons for your 
applications.

To disable the automatic application restart feature, create a 
STARTUP.CMD file in the root directory of your OS/2 boot drive with the 
following REXX script:
	/*  */
	call RxFuncadd 'SysLoadFuncs', 'RexxUtil', 'SysLoadFuncs'
	call SysLoadFuncs
	call SysIni 'USER', 'PM_WorkPlace:Restart', 'DELETE:'
	'exit'
or add the line SET RESTARTOBJECTS=STARTUPFOLDERSONLY to your 
CONFIG.SYS.  To manually disable automatic application restart when 
booting OS/2, hold down the left CTRL, left SHIFT, and F1 keys 
simultaneously from the time the mouse pointer appears until icons are 
displayed on the desktop.

Use the Alarms applet to automatically start programs at specified 
times.

If you wish to dispense with the Workplace Shell (and its overhead), 
particularly on low memory systems, change the line SET RUNWORKPLACE... 
in CONFIG.SYS to read SET RUNWORKPLACE=C:\OS2\CMD.EXE (replacing "C," if 
necessary, with a different drive letter).  In fact any program with job 
control (e.g. Enhanced Editor, HyperAccess/5) can be used as the shell.

To implement a small scroll back buffer for your OS/2 command line 
windows, use the command MODE CO80,102.  This procedure may be automated 
by adding "/K MODE CO80,102" in the Optional Parameters section of the 
OS/2 Window program object settings.

A clever way to manipulate files that are locked when the WPS is running 
(e.g. display drivers) is to add the line CALL=CMD.EXE at the end of 
CONFIG.SYS.  Then Shutdown and reboot.  The system will restart with an 
OS/2 command line prompt.  Type EXIT to proceed into the WPS.  Using 
CALL is also a convenient way to configure OS/2's serial ports using the 
MODE command.  For example:
	CALL=C:\OS2\MODE.COM COM2:38400,N,8,1,,,,,,,RTS=HS,BUFFER=AUTO
configures COM2 for high speed RTS handshaking and buffered I/O.

To shutdown without a mouse, press CTRL-ESC, select the Desktop, then 
press SHIFT-F10 and select Shutdown.

If your video driver does not support "seamless" Windows, try running 
the Win-OS/2 Program Manager in a DOS window.
