The 1542 is a bus-mastering card but has no cache.

I have my disk split into 10 partitions using DOS FDISK.

The normal kit is a stand-alone board.  Good if you are a UNIX user as
most UNIX's have support for the 154x built-in.  The Master Kit contains
the DOS and Novell drivers, along with a cable and more documentation.
The Master Kit is higher priced.  I have no idea what the street prices
are.
If you want to write your own, you would need the 154x Technical
Reference manual, an ASPI Programming Guide if you want to write ASPI
drivers and that should do it.  You can call 1-800-934-2766 for the
documentation.

There are many options for tape software under DOS/Windows.  You might
try Central Point, Cheyenne, SyTos Plus, and there are some public
domain programs around the net as well.  There are more solutions
available, but my pea-brain can't remember the 30 or so manufacturer's
that make it.

I remember reading in one of the trade rags earlier this year about the 
forced perfect termination scheme that IBM had developed for SCSI. This was
the only time I have really heard about it in any detail but even then the 
information was not that good, i.e. the writer described it as some kind of
electrical magic that he really didn't understand.

So my question is does anyone out there, especially anybody from IBM, have
some more detailed technical info on FPT or a pointer to where I can get
it.

Hi.  I am using OS/2 2.0+service pack right now.  My hard drive system is
currently a Seagate 80mb IDE (master, C: drive) and a Quantum 80mb (slave, D:
drive).  I want to add a SCSI controller to my system.  Since it is likely
I will upgrade my 386/25 to a 486+VLB in the near future,  I am interested in
both ISA & VLB scsi controllers.  I want to have them coexist w/ the IDEs.

	1)  I have heard about the 1542[abc];  whats the latest version?  
	I want one which supports SCSI-2.  Most importantly, what's the 
	cheapest price I can pay for one (I do not want any drivers -- 
	just a bare board since OS/2 has drivers), and where?

	2)  I have also heard about the Ultrastor 34f(?), a VLB SCSI 
	controller.  I presume that since it is new, it supports SCSI-2.  
	Does it have OS/2 2.0 drivers?  Is it compatible w/ other Ultrastors 
	or Adaptecs?  Is it any fast(er)?  Is it worth it?  OS/2 support 
	is a must - and not using the generic Int13 driver, but with its 
	own .ADD driver, so I can add CD-ROM, tape, etc, although I can wait
	awhile for specific drivers.  Again, what is the cheapest I can get 
	it for, and where?

	3)  Are there any others I missed?

	4)  Anyone have a used/spare 1542?

Thank you for your help.  Please reply to email, as I read news infrequently.

Mike.

I'm using a Soundblaster Pro and the 1542B without any problems. Other
than making sure the I/O port, IRQ and DMA settings didn't conflict
with somthing else, the installation was uneventful.

	Two things to remember about MTBF's:  1) MTBF can be cut in half when
the in-box ambient temperature rises 5 or 10 degrees C.  2) My friends in the
disk drive business tell me that power-down/up is roughly the equivalent of
15-70 hours of operation (their comments vary).  If your drives were being
powered up/down each day, say 300 days/year, plus say 30 hrs/week running,
that would be ~6000-22500 hours/year per unit, or .3 to 1.3 drive failures
per week, which is about what you observed (and that's assuming they're running
in cool temps).

In the case of ISC, embedded support consists of a space.c file for the
aha1540, for configuring it into the kernel.  It runs, I think, as an
ST-506 (right??) until you specifically configure the kernel for it.  I
believe this has been the situation since 2.0.2, maybe longer.

The double-buffer option causes smartdrv to allocate a physical buffer
below the 640K address and when disk I/O requests are trapped smartdrv
changes the address of the request to the buffer it allocated and after
the request completes it copies the data from the physical buffer to the
virtual address of the original request.  In effect is moving the data
around twice.

If you are using a 174x EISA adapter you can put it into enhanced mode
via the EISA configuration utility and get rid of the double_buffer flag
altogether as the enhanced mode BIOS contains the VDS specification
which allows the BIOS to get the physical address from the virtual
address passed in the INT13 call or you can load ASPI4DOS and use
standard mode to achieve the same thing.  In both cases you can
eliminate the double_buffer switch from smartdrv.

I have a couple of obsolete Charles Rivers Data Systems 68000 boxes,

to a SCSI controller?  The DK-120 has an Archive 9045L tape drive and a
Fujitsu 120MB SMD hard drive.  If I can get these to work with my PC it 
would save me some bucks.

Any words of wisdom would be a help. (Anyone from CRDS listening?)

These CRDS boxes were picked up for scrap prices and I don't want to put much
money into getting them to work on a SCSI controller.  

If you have access to documentation on the CRDS SASI info I would appreciate
a piece of mail.

Thanks,

Setup:

EISA 486DX50 with 16 MB, AMI BIOS dated 12/12/91
Floppy/IDE Adapter
Internal IDE Fujitsu M2624T, 520 MB, drive C:
Adaptec 1542B (BIOS V3.10), floppy disabled, everything else factory default
(resistor pack removed)
Internal SCSI HDD Toshiba MK-538FB (1.2 GB formatted, 1172 cyl), ID 0
Internal SCSI Tape Drive Wangtek 5150ES (resistor pack installed), ID 2
External SCSI CD-ROM Drive Toshiba TXM-3301B (resistor pack installed), ID 4
ATI Graphics Ultra with the InPort Mouse
2 Serial, 1 Parallel, 1 Game Ports

DOS 5.0 and OS/2 2.0 (GA+SP) installed on C: (dual boot), OS/2 HPFS partitions
on Fujitsu and Toshiba, Extended DOS partition on Toshiba. DOS sees only
1024 MB on Toshiba, OS/2 sees the whole disk (1172 MB).

Everything seems to work fine, except for Windows 3.1 if installed on Toshiba;
it will start only in standard mode (win /s). win, win /3, win /d:x, win /d:v
do not work. If installed on Fujitsu, Windows 3.1 works fine.

Anyway, when installing ESIX 4.0.4, only the Fujitsu drive is seen, the SCSI
hard disk is not recognized at all.

All SCSI devices are terminated properly, have the parity checking enabled,
and there are no IRQ conflicts (that I know of).

Once in a while, I saw a "Timeout Error: Error on port I/O with host adapter",
at boot time. I don't know if it was related to this, but I've changed now
the BUSCLK from CPUCLK/4 TO 7.159 MHz.

What is wrong with my setup? How can I install ESIX on both the IDE, and the
SCSI hard disks? What's the problem with Windows 3.1 on the SCSI drive?

Any help will be greatly appreciated.

Does anyone know if there are any Nubus cards for Macintoshes which
will give you a second scsi bus?   If so, what about the software to
support it?  On casual observation, the Mac system SCSI manager
doesn't look like it generalizes to multiple SCSI adapters.

Please email responses to :   sjk@netcom.com.  

Thanks,

I have an Adaptec 1522, and want to add to my computer a Toshiba internal
SCSI cd-rom drive. My question is what drivers do I need for this, where
do I get them, and how much do they cost? Also, if anyone has them lying
around without use, I wouldn't mind saving some money and buying them from
you.

I would appreciate any comments on:
1. the Seagate 11200N drive
2. Seagate drives in general
3. advantages, disadvantages of Fast SCSI
4. UltraStor controllers

I'm considering buying this for my Novell server.  I have not been happy 
with Seagate drives in the past, but I understand their large drives are 
better.  It is supposed to have a 5 year warranty, but frankly, I'd just as 
soon avoid the down time on the server, even if it is covered by warranty.

Is fast SCSI that much faster.  Are there problems associated with it that I 
should avoid.  What are the best controllers and drives that support fast-
SCSI (ISA bus).

Thanks for your help...
