Not sure if anyone said this yet, but you can enter root=/dev/hda2 (or
whatever device needed) at the lilo prompt to pass a different root at
runtime. Usually holding down left shift at the prompt allows you to type
boot time paramaters when the word "Lilo" appears. I've had the "Unable to
mount root device" kernel panic many times (due to chaning partitions
around, etc . . .), and I've been able to get around it by passing the root
at runtime. Once I've booted I can edit lilo.conf and fstab as necessary.

Subject: Re: Hard drive crash
The way you did it won't work because of the way you created the boot
disk (I am assuming that you created the boot disk with the with the
/boot partition on your dead drive).
You can use the rdev command to make corrections to the diskette.
example:
rdev /dev/fd0 /dev/hdb2
In the past, when I repartitioned my hard drive, I booted my distribution
CD, then before it did any work, I used a virtual terminal to get into a
standalone mode. From that mode, you can mount your root partition
and execute some commands, such as LILO and RDEV.
Also, I had a Western Digital 8GB drive go bad, and I sent the drive back
for a replacement at no cost except for my postage sending the drive to
them.
