-----BEGIN PGP SIGNED MESSAGE-----
The package with kernel for PS/2 Microchannel SCSI machines is now
available - file /pub/Linux/Incoming/ps2scsi.tgz at sunsite.unc.edu.
Hopefully, this will allow you to install Linux on your machine (use
Slackware 3.0 or another distribution based on Linux 1.2.13 kernel).
You should be able to run X Windows with XGA or XGA-2 adapter
(the generic VGA X server also works with VGA built into motherboard of
my model 70).
There are at least three variants of IBM MCA SCSI - plug-in adapter
without cache (I have it), plug-in adapter with cache, and built in
motherboard. Since the IBM Update manual (see below) never mentions
these and speaks only of "SCSI subsystem", I assume the kernel works
with all variants .
Files in the package:
readme.1st --- describes installation, X11 setup, lilo, bugs.
readme.2nd --- describes how to build a kernel with the driver.
readme.3rd --- for Cyrix Cx486DRx2 owners only, to enable on-chip cache.
vmlinuz --- 1.2.13 elf kernel build by gcc 2.7.0.
config --- for your information, options used to build the kernel.
ibmmca.c --- source for IBM MCA SCSI driver.
ibmmca.h --- header for the driver.
The 1.2.8 and 1.2.13 kernels are solid performers when reading/writing hard
disks - I've never seen them to crash unexpectedly. I have also built 1.3.15
and 1.3.20 kernels, and saw them crash 2-3 times.
All kernels I've built have a problem with CD-ROM. It is not very common,
usually I get through Slackware installation direct from CD without any
problems.
The source of information to write or improve the driver is "Update for the
PS/2
Hardware Interface Technical Reference, Common Interfaces", September 1991,
part number 04G3281, which you can order from IBM at 1-800-IBM-PCTB for
$21.75 (plus S&H). I ordered mine last November and it was on my doorsteps
in 2 or 3 days. The update contains hundreds of pages of fairly detailed
(at register level) information on diskette controller, keyboard and auxdev
controller, serial port controller, VGA, XGA, and SCSI subsystem.
