I was trying to follow the steps on this page: 
http://en.tldp.org/HOWTO/Kernel-HOWTO/quick_steps.html

But in the end, today I found the other tutorial
(which linked to this page) was easier to follow.

Now, I did a complete kernel compilation - but I've
got a nasty kernel panic I can't seem to fix:

The boot process stops and ends with these lines:

request_module[block-major-3]: Root fs not mounted
VFS: Cannot open root device "302" or 03:02
Please append a correct "root=" boot option
Kernel panic: VFS: Unable to mount root fs on 03:02


I don't know what to do to solve this - does it mean
my lilo.conf is incorrect or something? It says
root=/dev/ha2 as the error seems to imply (I added
that as I thought that was the problem)

Thanks !

Joris
