This is incorrect.  I've set up an Adaptec 1542 system with three SCSI devices
-- two hard drives and an MO drive.  The Adaptec might have a limitation of
requiring that hard drives have consecutive SCSI IDs starting at 0 (e.g., IDs 0
and 1 for the first two hard drives), though, and this might have confused you
if you didn't know about it.

Huh?  I'm afraid this makes *NO* sense to me.  OS/2 does not require that DOS be
run to create new partitions, period.  I used OS/2's FDISK to create the
partition on which DOS currently resides on my system (this one doesn't have an
Adaptec controller, but I don't think that should make any difference).  As to
the 1GB limit of DOS, that's the 1024-cylinder BIOS limit.  On most SCSI
controllers (including most Adaptec 1542s, I believe) it's possible to get
around this by setting a jumper or BIOS option.  It's also possible to simply
use that extra space as a non-boot OS/2 HPFS partition.  (See my mini-FAQ at
http://psych.colorado.edu/~rsmith/large-drives.html for more information on
this, though oriented more towards IDE systems.)

Again, this makes no sense to me.  The limit on FAT is 2GB (this will be raised
substantially with FAT-32, but that's another matter).  The limit on HPFS
partitions (including bootable HPFS partitions, assuming the 1024-cylinder limit
doesn't come into play) is much higher than this, though I don't recall the
precise value.  My hunch is that you tried creating an OS/2 partition that
extended past the 1024-cylinder mark (precisely 1GB in your setup), in which
case OS/2 won't install because the BIOS can't handle this.

LUN???  I suspect you mean SCSI ID; most modern hard drives don't support
separate LUNs, though some devices (like SCSI CD-ROM changers) do.

I believe the "no BASIC ROM" message indicates a problem at a much lower level
than the filesystem in use, like the system not finding any hard drives
connected, period.  My hunch is that you encountered a termination or SCSI ID
problem the first two times and not the third time.

Add the new drive as SCSI ID1 (be sure it's SCSI ID; if your drives *DO* support
LUNs, I can't guarantee how OS/2 would respond to that).  Partition it in OS/2
with no primary partitions and use it.  I've done this myself several times with
few or no problems.

I would have avoided FDISK completely and used Partition Magic 2.0 and used
System Commander to manage all the different operating systems on bootup. As
a matter of fact I have already done a similar thing. Besides DOS and OS/2, I also
have Linux running on my machine.

I cannot imagine where you have gone wrong.  
My old 486 with 1542 supported 5 devices (4 hard drives + one CD) with absolutely
no difficulty.  Disks were exchanged, installed and generally changed around with
never a blink.
I know it may sound silly, but you did ensure that your SCSI IDs were different?

This is only a problem under DOS. To have DOS use more that two devices
you need to install drivers. Under OS/2 having more that two devices
is no problem.

Installing onto a large disk can be a major problem thanks to
the brain-dead PC disk partitioning system,
