SubjectReboot during boot with 2.4.20 RedHat Boot Disk
I am trying to upgrade a RH 7.3 machine to RH 9 and the machine keeps
spontaneously rebooting when I boot from the boot disk.

The machine is an HP Vectra XU, dual Pentium 100, 32MB memory. It has
the beloved CMD640 IDE controller, but the hard drive and CD-ROM are
both SCSI - no IDE devices are installed. The machine has been running
various flavors of RedHat for about 4 years now, is currently running
7.3 and is stable - no overclocking. Just to rule out a recent
hardware failure, I ran Memtest86 overnight - no problems.

When booting from the RH boot disk, I capture the following from the
serial console:

At which point the machine reboots. When the machine comes back up,
many of the self tests fail (processor, cache memory, main memory,
floppy and a couple others) and the machine is pretty unhappy.
Resetting the machine or power cycling it fixes that problem.

From the point where it fails, I have suspected a problem with the IDE
probing, so I tried booting with "mem=24M", "mem=32M", "apm=off",
"nomce" and "noapic" without any luck.

"/sbin/lspci -v" produces the following:

Does anyone have any suggestions to help me?
