Could you boot into single user mode without root password?

If you are using LILO, specify one of these options at the LILO boot prompt (if you are using the graphical LILO, you must press [Ctrl]-[x] to exit the graphical screen and go to the boot: prompt):

boot: linux single

Then at shell prompt "#", type
passwd root   (to reset the password)

You'll need to mount the filesystem first. In that version of Redhat I'm not sure there was a dialog promt to do this. Firstly use fdisk to see which is the master partition, on many this is /dev/hda2, but use fdisk -p to be sure (make sure not to write with FDISK you don't want to modify the partitions, only view them *man fdisk*)
If it is an ext3 filesystem you would do (modify to ext2, or use without '-t' if not)

mount /dev/hda2 -t ext3 /mnt/filesystem
(you may need to mkdir /mnt/filesystem on older kernels)

chroot /mnt/filesystem

passwd
