I tried the booting from RAID-1 thing on one of my IDE systems.  It seems 
impossible with the current LILO because it writes different boot data to 
each drive, so if the first drive is removed the other drive becomes BIOS 
device 0x80 and won't boot because LILO expects 0x81.

The next version of LILO may address this...
