What makes a drive bootable is that the BIOS sees a partition as bootable, and you have bootblocks in the proper place.
All you need to do is make sure your use fdisk to mark the boot partition bootable, and make sure lilo gets run with that disk as a target. Please note the the scripts on the disk need to refer to /dev/dha if the make that reference. If you second disk is identical to the first (Exact same geometry) You can easily achieve this ultimate backup with dd if=/dev/hda of=/dev/hdc (Correct me if I'm wrong, check to make sure I am right.) YOU SHOULD BE IN SINGLE USER MODE TO DO THIS. Good luck. -- Hacksaw = David Charles Todd BBN Technologies = Hacksaw's Employer Hacksaw's Opinions != BBN Technologies' Opinions Linux understands you.
