Re: RH kernel upgrade
Redhat Kernel updates on a SCSI machine can be very tricky
(as you found out).
Did you rebuild your initial ramdisk image ("mkinitrd" command)?
Did you edit /etc/lilo.conf to reflect ALL of the changes?
(this sounds like your problem) You need to change multiple
lines to reflect the new version.
Did you rerun LILO?
It is possible to fix your system.
Did you have a boot diskette to boot your system?
If it will not boot at all, you can compile a custom kernel on a
different Linux box with builtin SCSI support to boot your system.
If you want to bring the PC to this week's beginner's meeting,
I can fix it for you.
