Just a suggestion: if you want to use both your RH and Debian OS's
then thrash lilo and go for grub (get 0.90). make a menu.lst in
/boot/grub to make life easier. Grub also offers better security than
lilo (via password and lock). I'm booting win98, debian and
qnx using grub and it works quite well.
try this menu.lst:
# wait for user input
timeout -1
# boot RH
root (sd0,0)
kernel /boot/vmlinuz-version root=/dev/sda1
# boot Debian
root (sd1,0)
kernel /vmlinuz root=/dev/sdb1
