Subject: RE: Restoring a PC Server 500 P/390
I Frankensteined a P/390 together out of a P/325 server and the PCI
P/390 card back in the day.
I am told the PCI card is rather choosy about which servers it will run in. The
system came with most of a P330 as well, but no case.
It is pretty picky. It did not run in a whitebox PC I had at the time, but the PC
Server 325 was close enough to its expected host that it was happy. I would
guess that any of the IBM x86 server machines from the right general era
would work.
That machine now lives at the Living Computer Museum in Seattle, although I
do not know if they have it available for use.
OK I got a PCI P390 card in the bundle of spares but have nothing PCI server style to run
it in.
Where I worked we binned loads of X330's which might have been usable...
It?s the RAID card that?s the problem, and it seems to have always been
temperamental. Did you use RAID in your P/325?
I don?t think I did. Have you tried just putting a different (OS/2-supported)
disk controller in and just not doing RAID?
That?s, in effect, what I did. Whilst there were Microchannel IDE Controllers I have never
seen one. There are no IDE interfaces on the "Planar" so every thing must be on
the MCA bus.
So I bought a BusLogic BT646 SCSI card on E-Bay. I also bought an Adaptec 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 >4GB drive option.
OS/2 has drivers for it so it works out of the box. The OS/2 boot disks find the drive and
install the proper drivers.
To compensate for the slower "narrow" drives I bought a SCSI2SD card that 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..
I used mine to run VM/CMS and Linux (under VM) quite well.
I was thinking of trying Linux. I assume you ran Debian?
Indeed I did, although also SLES. I assume you found my NASPA article on
Debian on 390 from 2004?
I think that?s the one...
