Hi Rod.  Now that my system is back to "normal", I deleted all
the partitions on my 4th physical hard disk (2.5 gig) and repartitioned it,
as 5, 500, 5, 1929, 5.  However, I cannot get fdisk (during the OS/2
installation) to set the 500 meg partition to "installable".  Is
there some limitation of OS/2 that I cannot boot off the 2nd pair of IDE
drives? I defined all the partitions as "extended logical".  I
have LBA enabled in my BIOS on both 2.5 gig drives.  When my SCSI drive was
my 3rd physical drive, I was able to install to it. BFN.  Paul.

P.S. I've sussed out the problem.  OS/2, for whatever reason, requires the
ENTIRE installable partition to be located in the first 504 meg.  Logical
partition is fine.  The NEXT problem is that I defined 100, 200, 2000+
partitions, and then attempted to install on the 200 meg partition.  And
guess what?  I've managed to reproduce the exact same error I got before! 
I set the 200 meg partition as installable, the OS/2 installation program
formatted the partition for me, then proceeded to load the first half of
OS/2 on the partition.  It then asked me to reboot, and I did, and instead
of continuing with the installation it said "No operating system found
- system halted".  Exactly the same as it did the original time!  And
then, I rebooted off my normal partition, and guess what?  The installation
disk, wouldn't chkdsk, it says an "unrecoverable error occurred".
 From memory, I got an error like this before.  Can't remember how I got
around that one, might have used OS/2 2.1 instead or something.  Anyway,
now that I've got a reproducable error, what is your theory as to what went
wrong?  Like I said, in the first installation, everything looked fine,
after all, I managed to install half of bloody OS/2 before the disk got
corrupted.  Now I know it's not my imagination, it's happening right now,
right before my very eyes.  I have a theory that if I switch my BIOS from
LBA to "LARGE" (I think I have such an option), OS/2 might be
able to install.  I will try that sometime soon.
