By default debian will keep two versions. I suggest also keeping a copy of
bf24 on there because it doesn't use an initrd.

When you boot you'll get a lilo prompt or a lilo menu. If it's the latter
choose a different kernel, probably labelled Linux.old.

If it's the former hit <tab> to get some time and a list of the available
kernel images, then type in the name of the kernel you want to boot.

If all else fails you can boot using a debian boot cd.

Boot to the initial men=FC, choose <F3> to see the available kernels. You'l=
l
want rescbf24. After the kernel name tell it what root filesystem to use.

rescbf24 root=3D/dev/hda1

That means the root directory is on the first partition of the first IDE
disk. Alter to match your situation.

The problem you're seeing is probably one of three things:

1: you don't have support for the filesystem on the root partition
2: you don't have support for the controller needed for the root partition
3: you're booting to the wrong root partition

mkinitrd should take care of the first two cases, but in the case of a SCSI
disk it might not have properly recognized the SCSI controller.

In the third case you need to figure out where the root partition is and
specify it similar to what's listed above.
