How to move linux drive onto separate IDE controller ? hdb -> hdd

1 Jan 2000

      Ive just upgraded my motherboard to a nice dual-PIII ( only 1 in tho )
and its got plenty of ide connectors.

So i want to move my linux drive onto a separate ide cable ( hdb -> hdd )

I tried editing, fstab, lilo.conf and running lilo but i get a kernel panic 
when im trying to load the drive.

Am I missing something ?
