[CentOS] 3.x box - lilo - hosed bootloader

Hi

Updated the firmware on a PERC RAID card as it was out of date and 
causing a monitoring error - Everything went fine but on the reboot the 
box now tells me it cant find a valid boot device - I am thinking maybe 
somehow the boot block on the logical disk is shot.

Can anyone advise me on how to rebuild the bootloader on lilo using a 
rescue CD?

thanks
