I thought I had captioned that picture. It's the original RAID controller
which I am not using. If I plug it in it starts the disks in the RAID array
which takes ages, and steals the hard disk BIOS vector which I need for the
SCSI card that's running the system.
I didn't want to remove it fully as I need to label the cables feeding it.
One feeds the top drive bays, and the other the bottom so if I ever need to
put it back it I need to know which is which.
If I get some free time I will have a go at starting the disks in it and
repairing the RAID array, and perhaps copy the disks that are installed.

I gotta ask, what's the deal with the dangling card? That cracked me up!
Thanks for posting some pics!

I have never seen one. There are no IDE interfaces on
the "Planar" so
every
thing must be on the MCA bus.

card as a spare. I think I struck lucky with the
BT646. It is a simple
SCSI/2 card,
no raid but it does have a BIOS with support for two
bootable drives and a

puts an SD card on the bus. OS/2 just sees it as a up
two four drives
depending on how I configure it. At present I have two 4gb drives. The
card
in it is 32gb so I can add 2 x 12gb drives or 1 x 24gb
or some other mix.
The CD
ROM sites on the same bus. I haven't tried the
tape drive yet..
Well I found an XGA2 card in the pile of bits so now I have 1024x768 display
resolution. I have swapped the CDROM for a SCSI DVD drive.
I managed to boot MTS and there are a few pics here:-

next job is to tidy up and re-assemble the case..

Some time ago I acquired a PCI P/390 card (along with
the various LIC
files). I
went down the same path as you to build a P/390 system
with OS/2 but I
kept running into problems with OS/2 versions and supported hardware.
I finally gave up and acquired a PCI based RS/6000 that I'll install AIX
on
and
have an R/390. ;-) I haven't had the time yet to
make any progress on
it.
But it's good to know that you've managed to do this if I decide to go
back
and attempt the PC route again.
