Ok, well I have a 250 and RH 6.2 set up just as you do, sans the dos
partion so .....

How about the fact you're beyond the 1024 cylinder limit? I notice you've
got 2 partions and I assume the /boot is on /dev/rd/c0c0p1 just because of
that problem...

The fix? Well, you could get the newest Lilo that is supposed to allow
booting beyond the 1024 cyl limit. I haven't tried it yet, but I've heard
that it works well is you bios supports what it needs.

Best
