OS/2 2.0 README (03/92)
_______________________

In OS/2* Version 2.0, IBM* performed the most
comprehensive testing ever done on any version of
the OS/2 operating system.  This included
extensive DOS, Windows, and OS/2 application
compatibility validation in addition to stress,
usability, and performance testing.  While most
users will not require the information in this
README, it contains unique application
compatibility information and other useful tips
and techniques that might be helpful in specific
situations.  Some of the information is intended
for the more advanced user or for the user already
familiar with various functions provided with OS/2
2.0.

The information was largely collected during the
final comprehensive system and compatibility
testing phases, which involved over 30,000 users
of early versions.  It was not finalized before
the publications were printed and we want to share
this information with you.

INSTALLATION
____________

o   After installation, and before you run any DOS
    or Windows program, we recommend you shut down
    your system.

o   Support for the High Performance File System
    (HPFS) was not added to your system if you
    installed OS/2 2.0 using either "Install all
    features" or "Install preselected features,"
    and your system:

    -   Has 6MB or less of memory, and
    -   Did not previously have HPFS support.

    To install HPFS support, use the Selective
    Install object in the System Setup folder.

o   If you select "Automatically update CONFIG.SYS
    and AUTOEXEC.BAT," some device-driver
    statements might not be copied to your new
    CONFIG.SYS file with a REM statement as stated
    in the "Installation Guide."  Select instead,
    "User edit CONFIG.SYS and AUTOEXEC.BAT" to
    copy these device drivers to your new
    CONFIG.SYS file.

o   The Setboot utility program supports an
    immediate-restart function that will restart
    the system to the specified drive without
    going through the Boot Manager Menu.  The
    parameter is /IBD:DRIVE, where "DRIVE" is the
    letter of a startable partition (for example,
    SETBOOT /IBD:E).  This example would start the
    logical drive E without displaying the Boot
    Manager Menu.  If the Boot Manager is not
    present, then only drive C can be specified.

o   If you are using Boot Manager, and one of your
    partitions contains OS/2 Version 1.3 with Dual
    Boot, copy BOOT.COM from the OS/2 2.0 \OS2
    subdirectory to the OS/2 1.3 \OS2
    subdirectory.

o   To enable the UNDELETE command, delete "REM"
    from the beginning of the following statement
    in the CONFIG.SYS file:

        REM SET DELDIR=

o   To use the ACDI support provided by PM
    Terminal, delete "REM" from the beginning of
    the following statement in the CONFIG.SYS
    file:

        REM DEVICE=d:\OS2\APPS\SASYNCDx.SYS

    where "d:" is the drive and "x" is either A or
    B.

    Then restart your system.

    If you selected the PM Terminal program with
    either "Select features and install" or the
    Selective Install object in the System Setup
    folder, the ACDI support is activated and you
    do not need to change the CONFIG.SYS file.

o   Following is additional information for the
    "Copying the Response File to a 5-1/4
    Diskette" section of Chapter 5 in the "OS/2
    2.0 Installation Guide."

    If you are installing OS/2 2.0 in a non-Micro
    Channel computer:

    -   Delete the following additional files from
        Installation Diskette 1:

            IBM2*.ADD
            *O2.SYS

    -   Delete the following from the CONFIG.SYS
        file:

            BASEDEV=IBM2FLPY.ADD
            BASEDEV=IBM2ADSK.ADD
            BASEDEV=IBM2SCSI.ADD

    If you are installing OS/2 2.0 in a Micro
    Channel computer:

    -   Delete the following additional files from
        Installation Diskette 1:

            IBM1*.ADD
            *01.SYS

    -   Delete the following from the CONFIG.SYS
        file:

            BASEDEV=IBM1FLPY.ADD
            BASEDEV=IBM1S506.ADD

o   IBM's testing of a beta Windows Version 3.1
    environment indicates that the OS/2 2.0
    Installation program will not configure your
    WIN-OS/2 desktop.  If the Windows directory
    that is found is from a Windows Version 3.1
    environment, either change the DOS PATH to
    point to a Windows Version 3.0 environment, or
    select the default environment.

o   If you have configured your system for a touch
    device, the System Configuration window in the
    Selective Install program will incorrectly
    show "PS/2 Style Pointing Device" as the
    default mouse selection.

    To change a touch device to a different
    pointing device, select "Mouse" on the System
    Configuration window, and then select the
    pointing device you want to use.  Finally,
    select the OK push button.

o   Occasionally, the Migrate Applications program
    might not find all applications.  In this
    case, retry the Find Programs operation.


WORKPLACE SHELL
_______________

o   Because of device-resource limitations, when
    too many applications are open, or when too
    many bit maps are visible on the screen, new
    icons, tabs, or other bit maps might not be
    drawn.  You can fix this situation by closing
    unused folders and applications so their
    device resources can be used by other
    processes.

o   In certain low resource situations, the final
    shutdown message might not appear after a
    shutdown is performed.  To ensure that
    shutdown has completed, wait until all disk
    activity stops before powering down or
    restarting your computer.

o   If you change the title of an object from
    within the Find Results folder, the name of
    the original object will be changed.

o   If you formatted your installation drive with
    HPFS, you might not be able to access files in
    the Desktop folder from DOS or Windows
    applications.

o   In the Help information for Find, disregard
    any references to page 2.

o   If you encounter a situation in which you
    cannot restart the operating system, press and
    hold the left Ctrl, left Shift, and F1 keys.
    This disables the automatic program startup
    feature of the desktop.  Press and hold the
    keys when the white screen first appears and
    hold them down until the icons appear on the
    desktop.

o   If you start the operating system and you do
    not see some of the system icons (such as OS/2
    System or Shredder), there is a function that
    will allow you to reset the desktop to its
    default configuration.  WARNING:  USING THIS
    FUNCTION WILL REMOVE ANY DESKTOP CUSTOMIZATION
    YOU HAVE DONE SINCE YOU INSTALLED THE
    OPERATING SYSTEM.

    To perform this function, do the following:

    1.  Restart the computer.

    2.  Before the first OS/2 Logo panel appears,
        hold down Alt+F1 for 20 seconds.

    When the operating system was installed,
    certain system files (CONFIG.SYS, OS2.INI, and
    OS2SYS.INI) were placed in the \OS2\INSTALL
    subdirectory.  When you perform the recovery
    function described above, the current versions
    of those files are automatically renamed and
    are replaced by the default installation
    versions.  If you have a STARTUP.CMD file,
    that file is also renamed, causing the startup
    feature to be deactivated.

o   If you were previously using the OS/2 2.0
    Limited Availability version and you installed
    OS/2 2.0 without reformatting, you might not
    be able to delete existing associations.  If
    this occurs, make a copy of the program object
    and discard the original.

o   If you were previously using the OS/2 2.0
    Limited Availability version and you installed
    OS/2 2.0 without reformatting, you must update
    the path and file name of

    -   OS/2 System Editor to \OS2\APPS\E.EXE
    -   Clipboard Viewer to \OS2\APPS\CLIPOS2.EXE


PRINTING

o   If you plan on using an HP PaintJet printer to
    print bit maps, make sure you set the
    printer-specific format check box in the
    queues option of the printer object.

o   If you are going to install the HP LaserJet
    printer driver over an existing driver, be
    sure to delete all the old *.FNT files FIRST.
    You can do this by deleting the printer driver
    from the Workplace Shell printer object and
    responding "Yes" when asked if the driver
    files should be deleted from the hard disk.

o   If you use the "print while spooling"
    printer-object setting, and your printer stops
    printing, close the job that was printing.

o   To improve the performance of viewing a
    network printer object, use a long refresh
    interval or set the interval to 0 (no
    refresh).

o   If you move the network object from the
    desktop to another folder, the network printer
    object template will not appear the next time
    you start the system. To make it reappear,
    move the network object back to the desktop
    and restart the system.

o   If you delete a printer definition, use the
    Delete option of the pop-up menu.


APPLICATION CONSIDERATIONS
__________________________

Most DOS, Windows, and OS/2 programs run under
OS/2 2.0 without any modification.  A few need
specific attention, such as changes to DOS
settings, for optimum performance.  Some
categories of programs, however, do not work
correctly with OS/2 2.0 because of their design,
or because they use undocumented interfaces, or
because they perform restricted activities.  The
following list identifies these categories of
programs.

1.  DOS extenders that require exclusive access to
    the 80386 control registers, such as the
    Virtual Control Program Interface (VCPI), are
    not supported because they would violate the
    integrity of the system.  The DOS Protect-Mode
    Interface (DPMI 0.9), the Expanded Memory
    Specification (EMS), and the Extended Memory
    Specification (XMS) are supported.

2.  Programs that directly address the physical
    disk sectors to perform disk-write operations
    are not supported.  These operations would
    violate the integrity of the system.  This
    category includes most DOS UNDELETE programs.

3.  Some Windows programs make use of the Windows
    accessory programs, like the Calculator.  If
    you already had Windows Version 3.0 installed
    and you did not format your hard disk when you
    installed OS/2 2.0, the accessory programs are
    on your hard disk and are supported by OS/2
    2.0.  However, the accessory programs are not
    part of the WIN-OS/2 environment included with
    OS/2 2.0.

4.  Programs (and hardware) that require the
    Windows Enhanced mode are not supported.  This
    mode uses an unsupported memory-management
    method.  Programs that run in the Windows
    Standard mode and Real mode are supported.

5.  Programs that manipulate the 80386 control
    registers, such as 386 DOS debuggers, are not
    supported; this would violate system
    integrity.

6.  The following fax boards and programs contain
    timing sensitivities that might prevent
    reliable operation:

    o   ATI ETC
    o   Cardinal FAX
    o   Practical Peripherals
    o   Smart Fax
    o   Twincomm 24/96

7.  For more reliable DOS communications
    performance on slower systems, the combined
    baud rate should not exceed 9600 bps for one
    or more concurrent DOS applications.

Our testing has identified the following programs
that perform one or more of the activities
described above.

o   Ansel for Windows
o   Bound Checker (DOS)
o   Central Point Backup for Windows
o   Close-Up (Windows)
o   Desert Storm CD-ROM (Windows)
o   Distinct Back-Up (Windows)
o   DoDot 3.0 (Windows)
o   Fax Concentrator (DOS)
o   Magic-CV (DOS)
o   Mathematica 2.0 (Windows)
o   MusicPrinter Plus 4.0 (DOS)
o   OmniPage Professional 1.0 (Windows)
o   Oracle (DOS)
    (There is an OS/2 version of this program.)
o   Perceive for Windows
o   Realizer 1.0 (Windows)
o   Sherlock Holmes CD-ROM (DOS)
o   Smart Fax (DOS)
o   Soft-ICE (DOS)
o   Splash 1.01 (DOS)

In addition to the restricted activities described
previously, some general conditions you should be
aware of are in the following list:

o   Some DOS and Windows programs run correctly
    only in full-screen sessions.  Any Windows
    program that does not use the Windows API to
    change the video mode should be run in a
    WIN-OS/2 full-screen session.

o   Some DOS and Windows programs must be
    installed or run in a "Specific-DOS" session;
    that is, in a session that was started by
    booting from an actual version of DOS.

o   Some programs run in OS/2 DOS or WIN-OS/2
    sessions, but require that you install the
    program under DOS.

o   Windows programs cannot start DOS sessions or
    DOS programs.

o   DOS programs that use low-level file system
    calls cannot access HPFS disks.

o   Code-page switching support is not available
    for graphics mode in DOS sessions.

o   Some DOS and Windows programs use security
    keys as protection against copyright
    infringement.  The security key is a 25 pin
    connector that is connected to the parallel
    port of the computer on which the program is
    executing.  The program checks to see if the
    connector is attached and, if the connector is
    not present, the program is assumed to be an
    illegal copy.  When more than one DOS session
    is running one of these programs, a SYS1799
    error can result.  This occurs because the
    programs that use these security keys do not
    de-allocate the parallel port if a second
    session is started for a program that also
    requires the security key.  This error is the
    result of a direct I/O parallel port
    contention mechanism that protects the user
    from possible data corruption.  To disable
    this mechanism press Ctrl-Alt-PrtSc while the
    DOS session that first performed direct I/O to
    the parallel port has the keyboard focus.

o   If your Windows Multimedia Extension programs
    do not work correctly after being migrated to
    OS/2 2.0, re-install them under WIN-OS/2.

The following list provides information about the
compatibility of specific programs with OS/2 2.0.
This information is version-specific; later
versions of the same program might operate
correctly.  Some program manufacturers already
have resolved incompatibility issues and have
fixes available; these are noted.

o   Action! Sampler 1.0 (Windows)

    -   The DPMI_MEMORY_LIMIT WIN-OS/2 setting
        must be set to 5 or greater.

o   Adobe Type Manager (Windows)

    -   When using an IBM 4029* printer in PPDS
        mode with Adobe Type Manager, some Windows
        programs may not function correctly.  If
        this occurs, do not use the printer
        resident fonts.  To disable printer
        resident fonts, bring up the control panel
        of the Windows Adobe Type Manager and
        ensure that the selection "Use Pre-built
        or Resident Fonts" is disabled.

o   After Dark (Windows)

    -   To run in a WIN-OS/2 window, change the
        object's settings to hide or minimize the
        icon to the desktop.

o   Aldus Pagemaker 4.0 (Windows)

    -   The spelling checker cannot locate the
        dictionary.
    -   Deselect the public setting to use the
        clipboard.
    -   If you experience incorrect output when
        spooling Standard format files to the
        printer, set the printing to RAW mode.  To
        do this, take the following actions:
        1.  Go to the Printer icon on the desktop
        2.  Select Open, then Settings, then Queue
            Options.
        3.  Ensure that Printer Specific Format is
            checked.

o   Aldus Persuasion 2.0 (Windows)

    -   Use the parallel ports to print.
    -   Deselect the public setting to use the
        clipboard.

o   Arts & Letters Graphics Editor 3.1 (Windows)

    -   The DECIPHS utility program requires that
        a DOS session be started from the Windows
        environment; this is not supported.
    -   To run in a WIN-OS/2 window, change the
        object's settings to minimize to the
        desktop.
    -   The directory created by Arts & Letters is
        named A&L.  The "&" character is a
        reserved character of the command shell,
        CMD.EXE; it is used for conjugated command
        lines.  To change to the A&L directory
        with the CD command you must use one of
        two methods of quoting the directory name.
        The first method is to prefix the "&" in
        A&L with a ^ (caret, shift 6):
        CD A^&L
        The second method is to surround the
        entire directory name with quotation marks
        ("):
        CD "A&L"
    -   If you are running Arts & Letters and you
        get a system error (a GDI trap), you must
        restart the operating system before
        running the program again.  This is
        because the program left a portion of
        itself running when it ended and will not
        start a new copy of itself while that
        portion is running.  This also means that
        when you restart the computer, Arts &
        Letters will start again automatically.
        It is recommended that you close the copy
        that is launched on system startup and
        start the program from its icon when you
        intend to run it in a window.

o   AutoCAD Version 10 (DOS)

    -   Close the program from the desktop.

o   AutoCAD (OS/2)

    -   Some of the background colors are set to
        an unusually pale color that does not show
        up well on XGA monitors.

o   AutoManager 4.0 (DOS)

    -   The version of the program that uses
        extended memory uses an unsupported DOS
        memory extender.  Use the real-mode
        version.
    -   The program expects COMMAND.COM to be in
        the root directory of drive C:\.  Copy
        COMMAND.COM from the C:\OS2\MDOS directory
        to C:\.

o   Borland C++ 2.0 (DOS)

    -   Set the DPMI_DOS_API DOS setting to
        ENABLED.

o   Central Point Backup for DOS 7.1 (DOS)

    -   Displays meaningless characters when
        running in a DOS window session.  Run this
        program only in a DOS full-screen session.

o   Central Point PC Tools Deluxe 7.1 (Windows)

    -   Many of the utility programs require
        starting a DOS session from Windows; this
        is not supported.  Start these programs
        from a separate DOS session.
    -   The backup feature of this program
        performs in a manner similar to Central
        Point Backup for Windows, which is in the
        list of programs that perform restricted
        activities.  If you experience difficulty
        backing up on a diskette, back up on an
        alternate device, such as a network drive
        or a tape drive.

o   Commander Keen (DOS)

    -   Set the VIDEO_RETRACE_EMULATION DOS
        setting to OFF.

o   Control Room 1.0 (DOS)

    -   You must run this program in a DOS
        full-screen session for the screen
        blanking feature to work correctly.

o   CorelDRAW 2.0 (OS/2)

    -   If you do a large amount of printing while
        in this program, it is possible that you
        might run out of system resources.  To
        avoid this, you should periodically save
        your work and exit CorelDRAW, then restart
        the program and continue your work.

o   CorelDRAW 2.0 (Windows)

    -   Install the program in a DOS session.
    -   Run the program in a WIN-OS/2 full-screen
        session.

o   CorelDRAW 2.1 (Windows)

    -   To install this program:
        --  Start a DOS session.
        --  Run FFIX /date (Note that "date" must
            be lowercase).
        --  Run WINOS2 (from the command line).
        --  Install the program.
        --  Exit WIN-OS/2.
        --  Run FFIX /u.
    -   Run the program in a WIN-OS/2 full-screen
        session.

o   dBase IV 1.1 (DOS)

    -   Set the DOS_FILES DOS setting to 30.  Set
        the DOS_VERSION DOS setting to
        DBASE.EXE,5,0,255.  With Hyperdisk, set
        DOS_VERSION to DBASE1.EXE,5,0,255.
    -   When using Hyperdisk, you might have to
        adjust the EMS and XMS memory limits.
    -   With the multi-user version, the program
        must be run in a Specific-DOS session.

o   Designer (OS/2)

    -   The MIRRORS.DLL that comes with this
        program must be installed in the program
        directory, as opposed to the C:\OS2\DLL
        directory, and the program must be started
        from this directory.  This is because OS/2
        2.0 comes with its own dynamic link
        library named MIRRORS.DLL.

o   Drafix CAD Version 1.11 (Windows)

    -   Run the program in a WIN-OS/2 full-screen
        session.

o   Drafix CAD Version 3.0 (Windows)

    -   Run the program in a WIN-OS/2 full-screen
        session.

o   Dynacomm Asynchronous OS/2 (OS/2)

    -   The DLL's included with this product must
        not be in the same directory as the
        executable file.  Put them in a separate
        directory and add that directory to the
        end of the LIBPATH.

o   Enhanced Editor (OS/2)

    -   The OS/2 Enhanced Editor supports up to 99
        fonts.  If additional fonts are installed,
        unpredictable results might occur.

o   F19 (DOS)

    -   Set the HW_ROM_TO_RAM DOS setting to ON
        and the VIDEO_RETRACE_EMULATION DOS
        setting to OFF.

o   F-117A Stealth Fighter 2.0 (DOS)

    -   Set the VIDEO_RETRACE_EMULATION DOS
        setting to OFF.
    -   If the program appears to stop at a blank
        screen soon after you start it, press ESC
        and the program will continue.  Once you
        are past the opening screens, the program
        runs correctly.

o   Fastback Plus 2.1 and 3.04 (DOS)

    -   If you experience difficulty backing up on
        a diskette, back up on an alternate
        device, such as a network drive or a tape
        drive.

o   FastLynx 1.1 (DOS)

    -   To use the serial port with this program,
        remove the DEVICE=C:\OS2\MDOS\VCOM.SYS
        statement from CONFIG.SYS.  Using the
        parallel port works correctly.
    -   Due to its high speed, the program
        sometimes fails.  If this occurs, simply
        end the program; system integrity is not
        compromised.  To minimize the possibility
        of this error condition, set the following
        DOS settings:
        HW_TIMER = ON
        IDLE_SENSITIVITY = 100
        IDLE_SECONDS = 10

        clicking on the box until a check-mark
        appears).

o   Intel SatisFAXtion

    -   The installation program displays the
        message "You have inserted the wrong
        diskette" when changing from disk one to
        disk two.  After the error message is
        displayed, press Enter and the program
        will continue with installation.
    -   At the end of installation of the Intel
        SatisFAXtion you are told to remove the
        diskette and press any key to reboot your
        machine.  Instead, shut down the operating
        system and restart your computer.
    -   If SatisFAXtion software is loaded into
        each DOS session, it might cause the fax
        to stop if another DOS session is started.
        Set up one DOS session to be used for
        faxing, and load the device driver and
        executable files only into that DOS
        session.  To do this, take the following
        steps:
        1.  Edit AUTOEXEC.BAT.
        2.  Cut the last two lines referring to
            the Intel SatisFAXtion board to the
            clipboard and save the file (using DOS
            Command File for the file type).
        3.  Open a New file.
        4.  Paste the last two lines into the new
            file.
        5.  Save the new file as FAX.BAT, using
            DOS Command File as the file type.
        6.  Edit CONFIG.SYS and cut the last two
            lines relating to the Intel
            SatisFAXtion board to the clipboard
            (cut only the last line if you do not
            have a scanner installed).
        7.  Save the file using Plain Text as the
            file type.
        8.  In the Command Prompts folder, select
            a DOS Full Screen icon, press the Ctrl
            key and mouse button two at the same
            time, move the mouse pointer to an
            empty area in the folder, and release
            the mouse button and the Ctrl key.
            This creates a copy of DOS Full
            Screen.
        9.  Put the mouse pointer over your new
            icon and press button two.
        10. Click on the arrow next to Open, and
            select Settings.
        11. Go to the Session page and select the
            DOS settings push button.
        12. Go to DOS_DEVICE and press mouse
            button one.  Move the mouse to the
            dialog area and press button one
            (there should be a blinking cursor
            now).
        13. Paste the text that you cut from the
            CONFIG.SYS file and select Save.
        14. Go to the General page and replace the
            contents of the Title box with FAX (or
            whatever other title you choose).
        15. If you want to edit the new session's
            icon, go to the General page and
            select the Edit push button.
        16. If you want to have this session start
            each time your system starts, move the
            icon to the Start Up folder.
        17. Whenever you start this session, type
            FAX to run the FAX.BAT file before
            using the SatisFAXtion board.
        Use the fax board in only one session at a
        time.

    -   If you opened a DOS session with the DOS
        LAN Support Program (LSP) device drivers,
        and subsequently closed the session, you
        must ensure that the Token-Ring Adapter is
        reset before using the LAN from another
        DOS session.  To ensure that the
        Token-Ring Adapter is reset, use
        RESETOKN.EXE or RESETOKN.SYS.  These files
        can be retrieved from CompuServe by
        issuing GO IBMOS2 and downloading
        RESTKN.ZIP from SECTION 17, IBMFILES, or
        they can be retrieved from the IBM

PERFORMANCE
___________

Following are some performance considerations that
you should be aware of.  For more performance
guidelines, see the "Information and Planning
Guide" document that can be obtained through your
point of purchase or retrieved through CompuServe.

The minimum memory requirement for OS/2 2.0 is
4MB.  (This includes up to 128KB that is used on
some machines for ROM to RAM remapping).

Some systems use more than 128KB for other
purposes, so less than the minimum required memory
is available.  On these systems, you might need
another 512KB to 1MB to satisfy the minimum
requirements.  Check your system to see if it
offers a way to return the memory so that you can
return to the minimum requirement.

Users concerned with response times when using
some system functions, such as loading programs,
starting sessions, and switching between sessions,
can improve performance by increasing system
memory.  If you are running on a constrained
system (small hard disk, 16-MHz or less processor,
4MB of memory), an additional 2MB of memory will
improve performance.  In the entry memory system
(4MB), the recommended file system is the FAT file
system.


SWAPPER FILE

The system automatically pre-allocates the
SWAPPER.DAT file based on the size of installed
memory.  This is done to optimize performance and
reduce disk fragmentation.  To tune the size of
the swapper file, see the information about
SWAPPATH in the "Command Reference."


FILE SYSTEMS

Many performance changes have been incorporated
into OS/2 2.0 File Systems.  Both file systems
read ahead (for sequential I/O), lazy write to
disk, and accept threshold parameters.

A disk cache size is preselected by the system
based on installed memory, disk size, and file
systems installed. The default for the entry
memory system (4MB) is a cache size of 128KB.  To
tune the size of the disk cache, see the
information about DISKCACHE in the "Command
Reference."


DOS APPLICATIONS

You can improve the performance of some DOS
applications by adjusting the DOS settings.  If
the application does not require extended or
expanded memory, these values can be set to zero.
This will provide maximum performance.

Some DOS applications use polling techniques to
poll the system for work. An example is an
application that appears to be idle at an input
prompt, but is in fact polling the keyboard
looking for keystrokes.  Use the IDLE SENSITIVITY
choice to detect this occurrence and put the
application to sleep when it is polling.


WINDOWS APPLICATIONS

Windows applications are generally started in one
WIN-OS/2 session, unless specifically set to run
in their own WIN-OS/2 session.  If you use several
applications simultaneously, you might want to
increase the DPMI memory limit before starting the
first application.  The first application started
determines the DPMI memory available for all
subsequent Windows applications that are used.

In low memory configurations, you can run multiple
Windows applications in one WIN-OS/2 session. This
reduces both memory and swapper-file requirements.

With a WIN-OS/2 window session, a new session is
created every time you double-click on an active
object.  To restore the currently active object:

o   Double-click on the minimized application
    object, or
o   Display the OS/2 Window List and double-click
    on the application name.

If you choose to migrate your Windows applications
(at installation time or later using MIGRATE),
most Windows applications will execute in one
WIN-OS/2 session.  If you set up a Windows
application and do not use MIGRATE, each program
executes in its own WIN-OS/2 session.

If you are running Windows applications in a
single WIN-OS/2 session, the Windows clipboard can
be changed from PUBLIC to PRIVATE for increased
performance.  Setting it to PRIVATE means that it
can be used in the single Windows environment
only.

When a large volume of data is being sent to the
clipboard in a WIN-OS/2 Window session, you might
receive the message:

  Data not saved, possible memory or disk space error
   This data not available in clipboard

followed by the message:

  Do you want to exit clipboard?

Selecting OK to the second message will make the
clipboard private to that WIN-OS/2 session.  Data
that was previously sent to the public clipboard
might have remained private.  You might want to
use the private clipboard for applications seeing
these messages.

When you exit from a WIN-OS/2 session, the system
leaves the clipboard and DDE loaded.  If you will
not be returning to a WIN-OS/2 session, close both
the clipboard and DDE.  Use the PM Window List to
see if they are active.

To permanently disable public DDE and clipboard
interchange between Windows applications and PM
applications, and between Windows applications in
separate WIN-OS/2 sessions, edit the
\OS2\MDOS\WINOS2\SYSTEM.INI file.  In the [boot]
section you will find the names of these two
programs in the SAVDMApps= line, the MAVDMApps=
line, and the WOS2VDMApps= line.  By removing the
names of the programs from these lines, the
programs will not be automatically started.
Adding them back will cause them to be started the
next time a WIN-OS/2 session starts up.


APPLICATION USAGE

If you have an application that you always use,
you can set up the application in the Startup
folder to load when the system is started.

To avoid reloading frequently used applications,
minimize the application after use and simply
maximize it to use it again. You can find the
application in the window manager.

If you use several different applications, the
icons (objects) can be placed on the desktop or in
a folder.  The folder can be set to open when the
system is restarted.


FREEING MEMORY

Close opened applications when you are not going
to use them again.

Close folders that you do not need.  Also move
commonly used functions out of folders and onto
your desktop, and close the folders that contained
the icons.


REDUCING HARD DISK SPACE

To save hard disk space, be certain to install
only the functions you need.  If you have
installed the productivity aids and the games, and
later only want a subset of these, delete all
\OS2\APP and \OS2\APP\DLL files and use INSTALL to
selectively install the items you want.
Additionally, delete TUTORIAL.HLP in
\OS2\HELP\TUTORIAL if you no longer need the
tutorial.


WINDOWS VERSION 3.0 PROGRAMS SUPPORT
____________________________________

o   If you are running WIN-OS/2 window sessions,
    you cannot have any statement in the
    AUTOEXEC.BAT file that prompts the user for
    input.

o   If you are running a WIN-OS/2 full-screen
    session and you have an 8514 display, use DOS
    Settings to set VIDEO_8514A_XGA_IOTRAP to OFF
    and VIDEO_SWITCH_NOTIFICATION to ON.

o   Current information for WIN-OS/2* window
    sessions in high-resolution video modes will
    be available from CompuServe, the IBM National
    Support Center Bulletin Board System, the OS/2
    Bulletin Board System, and IBMLINK.

o   Do not use the SETUP.EXE shipped with Windows
    3.0.  Instead, use the SETUP.EXE shipped with
    WIN-OS/2 to ensure your environment will be
    properly maintained for use in OS/2 2.0.  Use
    the Selective Install choice (in OS/2 2.0) to
    change video drivers for VGA, 8514, XGA*, EGA,
    and CGA, and for mouse drivers.

o   If you are running a WIN-OS/2 full-screen
    session with an XGA video device driver and
    your Windows icons are not clear, use the
    Control Panel to choose another color scheme
    for the WIN-OS/2 desktop.

o   Do not change mouse buttons from the WIN-OS/2
    Control Panel if you are using WIN-OS/2 window
    sessions.  Change mouse buttons from the
    Workplace Shell to change the WIN-OS/2 mouse
    buttons in the WIN-OS/2 environment. The
    WIN-OS/2 Control Panel can still be used for
    changing mouse buttons in WIN-OS/2 full-screen
    sessions.

o   If the VIDEO_SWITCH_NOTIFICATION setting is
    ON, wait until you see your WIN-OS/2 desktop
    in a full-screen session before switching back
    to the Workplace Shell desktop.  If the
    session does not start successfully, close it
    then restart it.

o   The value for VIDEO_SWITCH_NOTIFICATION should
    not be changed for an active WIN-OS/2 session.

o   Clipboard and DDE default to PRIVATE in
    real-mode WIN-OS/2 sessions.

o   If you install the USA (English) version of
    OS/2 2.0, and you want to change the system
    configuration to another country or language,
    run Selective Install to make the changes
    effective for PM.  To make the changes
    effective for WIN-OS/2, start WIN-OS/2 in
    full-screen mode, open the Control Panel, and
    use the international option to make your
    changes.

o   The EXPAND.EXE utility program for WIN-OS/2 is
    located on OS/2 2.0 diskette 9.  This program
    is required to expand Windows device drivers
    supplied by equipment manufacturers.


PRINTING

If your printer is connected to LPTx or LPTx.OS2,
be sure that the OS/2 spooler is active and the
Windows spooler is disabled.  When the OS/2
spooler is active, Windows applications print jobs
from Windows applications spool directly to the
OS/2 spooler.  Therefore, multiple print jobs can
be spooled asynchronously from the same WIN-OS/2
session or multiple WIN-OS/2 sessions.  This does
not apply for printing to COMx devices, as there
is no spooling for COM devices.


VIDEO/GRAPHIC SUPPORT
_____________________

OS/2 2.0 fully supports EGA and VGA.  Because of
the highly graphical user interface provided by
the Workplace Shell, use of OS/2 2.0 in CGA mode
will be difficult and is not recommended.
Applications designed for CGA mode are supported
and can be run even when OS/2 2.0 is running in
EGA, VGA, or SVGA mode.  Resolutions above VGA
(640x480x16 colors) are referred to as Super VGA
(SVGA).  However, the implementation of SVGA
varies widely and requires different device
drivers for different resolutions, as well as
different adapters and systems.  The OS/2
Installation program will correctly configure
Presentation Manager* and WIN-OS/2 drivers for
8514 and XGA.  All SVGA adapters are supported in
VGA mode with the VGA driver provided with OS/2
2.0.


SVGA

The base video system and virtual display device
driver in OS/2 2.0 have been enabled for some of
the most popular SVGA chips and boards.  This
support is required to switch between PM and DOS
or WIN-OS/2 applications.  Because of the many
implementations and video modes, a limited number
of video boards have been tested.

The following Super VGA boards have been tested
and found to work with OS/2 2.0 for DOS
applications that make use of SVGA modes:

o   Orchid ProDesigner IIs by Orchid Technology
    (ISA and MCA versions)
o   Trident TVGA by Trident Microsystems, Inc.
    (8900b and c levels)
o   STB PowerGraph VGA by STB Systems, Inc.
o   Video Seven VRAM II, by Video Seven
o   Boca Super VGA by Boca Research Inc.
o   VGA Wonder XL Series by ATI Technologies, Inc.

The 8514 Ultra by ATI must be installed as an 8514
and as a primary display; it will default to
high-resolution mode.  Do not install it as VGA.

Please contact the manufacturer of your PC or SVGA
video adapter to obtain device drivers and
installation instructions if you want to run
Windows or OS/2 applications in SVGA modes.
Information about SVGA support will be available
on CompuServe, the National Support Center
Bulletin Board System, the OS/2 Bulletin Board
System, as well as many video-board and system
manufacturers' bulletin boards.

We recommend you do NOT run the video-adapter test
utility programs in OS/2 2.0 unless the
manufacturer has explicitly verified that they run
in OS/2 2.0.

Some video adapters require that the computer's
DOS BIOS initialize the video adapter correctly.
If you have one of these adapters, screen text
might appear distorted in an OS/2 full-screen
command prompt.  To remedy this, start a DOS
full-screen command prompt, type EXIT, and then
switch back to the OS/2 full-screen session; the
text should appear normal.

To automate this process, you can create a DOS
batch file to run when you start your computer.
Add the following statement to STARTUP.CMD:

   START /FS /DOS DOSFS.BAT

Create the file, DOSFS.BAT, and place the
following statement in it:

   EXIT


SVGA ON UTILITY

If you have one of the above video adapters and
want to run DOS or Windows applications that make
use of SVGA, you must turn on OS/2 2.0 SVGA
support.  The OS/2 Installation program detects
the type of video chip in the system; it cannot
detect the type of adapter or system board that
the video chip has been implemented on.  You must
determine that you have a supported configuration,
and then explicitly enable SVGA.

To enable SVGA, type the following at an OS/2
command prompt or DOS full-screen command prompt:

   SVGA ON

Then restart the system.

When the Installation program detects a supported
SVGA video chip (other than 8514 or XGA), it will
add the following line to the CONFIG.SYS file:

    DEVICE=(OS/2 drive):\OS2\MDOS\VSVGA.SYS

Execution of SVGA ON creates the configuration
file, SVGADATA.PMI, in the \OS2 directory.  This
file is used by VSVGA.SYS to save and restore the
correct video registers when switching between DOS
or Windows programs and Presentation Manager.
Failure to enable SVGA will cause display errors
when switching between applications that use SVGA.

NOTES:

1.  Over time, more display adapters and PC
    systems that offer SVGA, will be tested.
    Refer to the bulletin boards mentioned
    previously, or to the manufacturers for the
    latest support information.

2.  To make use of SVGA modes, you also must
    install Windows and Presentation Manager video
    display drivers.

3.  If you experience display errors on an
    SVGA-enabled system, try disabling SVGA
    support by typing SVGA OFF at a command line.
    This will delete the SVGADATA.PMI file.  Then
    restart your system.

4.  In some SVGA displays, if you switch to the PM
    desktop while the screen is still drawing, you
    might experience display errors on the PM
    desktop.  Switch back to the SVGA screen,
    allowing the drawing to complete, and then
    switch back to the PM desktop.


DUAL DISPLAYS

In multiple XGA configurations, when you switch
from DOS to the PM desktop, your system will not
save and restore the hardware registers.

If your machine has an 8514 Ultra adapter and an
OS/2 2.0 supported SVGA adapter, you will need to
change the DEVICE= statement in your CONFIG.SYS
file from VVGA.SYS to VSVGA.SYS.


LAPTOP LCD OR MONOCHROME PLASMA DISPLAYS

To change the color schemes for OS/2 system
windows and create a more readable display image,
change the Scheme Palette as follows:

1.  Use your Reference Diskette or hardware Setup
    program to set your hardware to VGA color, if
    possible.
2.  Open the System folder.
3.  Select System Setup.
4.  Select Scheme Palette.
5.  Select the right-hand monochrome scheme.

This procedure will optimize the color scheme for
gray-scale usage, and also provide a good set of
colors for a VGA desktop presentation.


GRAPHICS

Several fonts have been enhanced in OS/2 2.0.
Some existing applications use inappropriate font
metrics to scale their text.  In some cases, the
text becomes clipped because it no longer fits the
available space.


RUNNING VGA PM AND WIN-OS/2 WINDOW SESSIONS IN VGA
AND WINDOWS FULL-SCREEN SESSIONS IN HIGH
RESOLUTION MODE

When running a full-screen WIN-OS/2 session with
an 8514 adapter in high resolution (8514.DRV
mode), do not switch away to a different session
while an application is updating the screen or
displaying the hourglass.

The following is a procedure for enabling WIN-OS/2
full-screen sessions to run in high-resolution
mode while the Workplace Shell Desktop and
WIN-OS/2 window sessions run in medium-resolution
(VGA) mode.  The procedure assumes you are not
familiar with the SYSTEM.INI and WIN.INI files.

Follow the instructions very carefully.
Otherwise, you could cause your WIN-OS/2 sessions,
both window and full-screen, to become inoperable.

1.  Install OS/2 for medium resolution VGA.

    The next step requires you to make backup
    copies of your SYSTEM.INI and WIN.INI files.
    DO NOT SKIP THIS STEP.  It is assumed that you
    have a diskette or tape backup copy of your
    system; instructions follow for a backup in
    the directory only.

2.  Back up the SYSTEM.INI and WIN.INI files.

    Open an OS/2 Window from the Command Prompts
    folder in the OS/2 System folder.  At the
    [C:\] prompt, type the following and press
    Enter:

       CD\OS2\MDOS\WINOS2
       COPY WIN.INI WIN.BAK
       COPY SYSTEM.INI SYSTEM.BAK

    Before making changes to the files, be sure
    the desired high-resolution Windows device
    drivers and fonts are loaded in the system.

3.  Check the \os2\mdos\winos2\system directory
    for the desired high-resolution display device
    driver.  In this example, the XGA.DRV device
    driver is used.  Checking this directory
    reveals that this device driver is not loaded.
    (The device driver might be loaded already, if
    the system was installed in high-resolution
    mode and then Selective Install was run to
    return to VGA mode.)

    For XGA, the diskettes need to be searched for
    WINXGA and *G.FON.  The following shows the
    sequence of entries.

       DIR A:WINXGA
       DIR A:*G.FON

    No XGA drivers were on this diskette, but one
    of the font files was.  Although the font file
    is not in a bundle of files, it is still in
    packed format and must be unpacked.

    The files are packed with their standard
    target directory coded into the packed file.
    To copy the file to the system disk in the
    proper directory, just run the Unpack utility
    program.

       UNPACK A:SYMBOLG.FON

    This procedure continues until all of the
    scalable fonts are unpacked.  These fonts are:

    o   SYMBOLG.FON
    o   TMSRG.FON
    o   COURG.FON
    o   HELVG.FON

    Eventually the WINXGA file is found by the
    dir a:WINXGA search.  It contains the WIN-OS/2
    XGA.DRV and three XGA fonts.

       UNPACK A:WINXGA

    With all of the required driver and font files
    on the system disks, the next step is to
    modify the SYSTEM.INI file.

4.  Edit the SYSTEM.INI file and find the
    following line:

       display.drv=vga.drv

5.  This line specifies what device driver
    WIN-OS/2 is to use in full-screen sessions.
    Change this line to point to the
    high-resolution device driver that was
    unloaded in the steps above. In this example,
    the device driver is XGA.DRV.  The modified
    line should look like the following:

       display.drv=xga.drv

    Both SYSTEM.INI and WIN.INI have font entries
    that must be changed.  In SYSTEM.INI, these
    entries are:

       fixedfor.fon=vgafix.fon
       oemfonts.fon=vgaoem.fon
       fonts.fon=vgasys.fon

    For XGA, these entries must be changed to:

       fixedfor.fon=xgafix.fon
       oemfonts.fon=xgaoem.fon
       fonts.fon=xgasys.fon

    In WIN.INI, the entries:

       Symbol 8,10,12,14,18,24 (VGA res)=SYMBOLE.FON
       Helv 8,10,12,14,18,24 (VGA res)=HELVE.FON
       Tms Rmn 8,10,12,14,18,24 (VGA res)=TMSRE.FON
       Courier 10,12,15 (VGA res)=COURE.FON

    Must be changed to:

       Symbol 8,10,12,14,18,24 (XGA res)=SYMBOLG.FON
       Helv 8,10,12,14,18,24 (XGA res)=HELVG.FON
       Tms Rmn 8,10,12,14,18,24 (XGA res)=TMSRG.FON
       Courier 10,12,15 (XGA res)=COURG.FON

When these changes have been made and the INI
files saved, the system is ready for running
Windows applications in WIN-OS/2 window sessions
(VGA mode) and WIN-OS/2 full-screen sessions
(high-resolution mode).

For 8514 displays, you must delete the following
line from CONFIG.SYS:

  DEVICE=C:\OS2\MDOS\V8514A.SYS

For 8514 displays, the files to find are:

o   WIN8514 (contains 8514.DRV, 8514SYS.FON,
    8514OEM.FON, and 8514FIX.FON)
o   COURF.FON
o   TMSRF.FON
o   HELVF.FON
o   SYMBOLF.FON.


NOTES:

Windows developers should note that their
debuggers work in full-screen only.  If you have a
dual-monitor setup (8514+VGA), install OS/2 2.0
for the 8514 as primary display with no secondary
display.  This will allow your Turbo Debugger for
Windows (TDW) or CodeView for Windows (CVW)
session to run full-screen on the VGA display
while the WIN-OS/2 session runs full-screen on the
8514.  For CVW, make sure to use the /8 option.
Quick C runs on the same display as WIN-OS/2.  If
you use Quick-C, you don't need a special video
configuration.

Installing OS/2 2.0 in this way will allow PM to
run on the 8514, and your full-screen debugger to
run on the VGA.  It also will provide a "stereo"
effect for all full screen sessions; both the 8514
and VGA will show the same picture, unless a
full-screen application takes advantage of
video-specific features.

ADAPTEC AND FUTURE DOMAIN SCSI SUPPORT

Device support for the following Adaptec and
Future Domain SCSI adapters is shipped with OS/2
2.0.  When any of the following adapters is
installed in a workstation, its presence is
normally detected automatically, and the
appropriate device support is subsequently
installed.  For reference, the names of the device
drivers that support each adapter are provided
here:

   SCSI Adapter                        Device Driver
   or Interface                        filename

   Future Domain MCS-600/700           FD16-700.ADD
   Future Domain TMC-850IBM            FD850IBM.ADD

The TMC-850/860/875/885 and TMC-850IBM adapters
will not be detected when the adapter's BIOS is
disabled.  You can manually install this support
in your system by following the steps below.

NOTE:  "xxxxxxxx.ADD" should be replaced with the
       file name of the device-driver file you
       want to install.

1.  Locate Installation Diskette 8, which contains
    the file, DASDDRVS.

2.  Insert the diskette in drive A.

3.  Change the current directory to the root
    directory of the startup drive.

4.  Type:  UNPACK A:DASDDRVS \OS2 /N:xxxxxxxx.ADD

5.  Add the following line to the CONFIG.SYS file:

       BASEDEV=xxxxxxxx.ADD

6.  Restart the system.


OS2SCSI.SYS Replaces SCSI.SYS

The device driver, SCSI.SYS, has been replaced by
OS2SCSI.SYS.  OS2SCSI.SYS is provided in the \OS2
directory of the boot partition.  Any CONFIG.SYS
entries of the form "DEVICE=SCSI.SYS" should be
replaced by the entry "BASEDEV=OS2SCSI.SYS."
Normally, this is done automatically.

The OS2SCSI.SYS device driver is required for a
number of SCSI CD-ROM devices, SCSI Read/Write
Optical devices, and SCSI Tape devices.


SCSI CD-ROM Support

The SCSI CD-ROM support built into OS/2 2.0 has
some manufacturer-specific dependencies at this
time.  Support has been verified for IBM and
Toshiba SCSI CD-ROM drives.  Information about the
support and verification of additional
manufacturers' drives will be made available at a
later date.


SCSI Removable Media Support

Full function support is not yet available for
SCSI hard disk drives that support removable
media.  Examples of this class of device include
the "Bernoulli" drives manufactured by IOMEGA, and
the removable-media drives manufactured by SyQuest
Technology.

Although OS/2 2.0 recognizes these drives, it will
treat media as large diskettes.  You will be able
to format for the FAT file system only.  You will
not be able to partition or start up from the
media, and partitioned media will not be
recognized.

If the IBMINT13.I13 driver is used to control
these units, the drive will be treated as a fixed
drive.  In this case, the cartridge must be in the
drive at startup time, and you will need to use
the Shutdown procedure to remove the cartridge
from the drive.


SCSI Usage Notes

Following are a number of notes about usage, and
about potential compatibility problems with the
microcode levels on various adapters and devices.

 Adapter:  All Adaptec adapters
 Note:     SCSI hard disks must be configured as
           SCSI target ID 0 or 1 to be able to
           start up from that hard disk.

 Adapter:  Adaptec AHA-154x
 Drive:    IBM 0661 - 320MB SCSI
 Note:     Adapter BIOS will not recognize the
           drive as Target 0 or 1 (Drives 80, 81).
           For OS/2 2.0, the drive can be used as a
           non-startup drive.

 Adapter:  Adaptec AHA-174x
 Drive:    IBM WDS-3180 - 80MB SCSI, IBM WDS-3160
           - 160MB SCSI
 Note:     Adapter will not recognize these drives
           when configured in 'STANDARD MODE'
           (AHA-154x emulation).  Instead, the
           AHA-174x adapter should be configured in
           'ENHANCED MODE'.  This mode is supported
           by the OS/2 2.0 drivers, and the problem
           does not occur when the adapter is
           operating in enhanced mode.

 Adapter:  Future Domain TMC-850/860/875/885 w/BIOS
           revision level 7.0.
           Future Domain TMC-1660/1670/1680 w/BIOS
           revision level 2.0.
 System:   IBM Models 35 and 40 when the Future Domain
           adapter is controlling the startup diskette.
 Note:     Will produce the message, "Disk read error
           has occurred" when you attempt to start the
           Installation diskette.  Contact Future Domain
           for a free BIOS upgrade.


AMI SCSI Adapters

AMI "Fast Disk" and AMI "Fast Disk II" SCSI
adapters are incorrectly recognized as Adaptec
adapters.  If you have one of these adapters in
your system, do the following:

o   At the final restart after the installation is
    complete, delete from the CONFIG.SYS file, any
    line with "BASEDEV=AHA1xxx.ADD" (where "x" can
    be any character).
o   Ensure the line, "BASEDEV=IBMINT13.I13,"
    appears in the CONFIG.SYS file.


FORMATTING DISKETTES

If you have a non-Micro Channel system with a
5-1/4" drive and its 3-1/2" drives all support
media sense, your 5-1/4" drive will format
diskettes at 720MB.  Previously formatted 1.2MB
diskettes will read and write correctly.  A fix
for this problem can be obtained from the
electronic bulletin board described in the
"Service and Support Information" section of this
file.


CD-ROM SELECTIVE INSTALL

When installing CD-ROM using "Selective Install",
do not install other options at the same time.
