They're all marked as empty, or unoccupied, or whatever terminology
was used.

The 2.2.0-pre9 kernel does see a SCSI adapter here, but it panics:

IBM MCA SCSI: integrated SCSI found, io=0x3540, scsi id=7.
IBM MCA SCSI: Removing current logical SCSI-device mapping.
IBM MCA SCSI: Probing SCSI-devices.<0>Kernel panic: IBM MCA SCSI: command error. Last SCSI_CMD=0x0.

In interrupt handler - not syncing


The 2.1.30 ibmmca.[ch] files won't work with 2.2.0-pre9. There are
changes to the SCSI code which are beyond my ability to reconcile.

I've tried building kernel 2.1.30, but it does not compile. So I tried
2.1.31, and *that* doesn't compile, either. And neither does 2.1.32!

I get this:

gcc -D__KERNEL__ -I/usr/src/linux/include -D__ASSEMBLY__ -D__SMP__ -traditional -c locks.S -o locks.o
/tmp/cca07070: Assembler messages:
/tmp/cca07070:66: Error: operands given don't match any known 386 instruction
/tmp/cca07070:69: Error: operands given don't match any known 386 instruction

Of course, there are far less than 66 lines in locks.S....
This is with gcc 2.7.2.3, and binutils 2.9.1 (with BFD 2.9.1.0.15).

Naturally this occurs right near the end of the build, so it takes quite
some time to learn that I've just wasted a whole lot of time.

What kernel version should I try to use? Should I downgrade binutils
to something ancient? All I want is a relatively stable desktop
system, which can see the (216 MB IBM MCA) SCSI hard drive and the
(IBM) token ring card. I'm not afraid to mix-and-match files between
different kernel versions, but randomly trying different combinations
is going to take *way* too long.

Ah. The documentation says that that one's for the "9556/9557", not the
Model 56, so I didn't recognize that it was what I wanted. I used that
to verify that this PS/2 does indeed have a SCSI adapter and a SCSI disk.

The ibmmca.c driver does not work (see above).

No, this has a push-button on the front panel.

I have no budget for this, and no knowledge of where to find used MCA
hardware. I'm just absolutely sick of Windows 3.1. I've been able to
use Linux at every place I've worked before, except here (so far). The
PS/2 machines I have available already have the MCA SCSI cards in them.

I'm trying to avoid buying any hardware unless I have to. This is both
because it will come out of my own pocket, and because making dramatic
hardware changes to any of the PCs here could be seen as a territorial
violation. Not only am I in the Unix support group, rather than the
desktop support group, but I'm also a contractor, not an employee.
