what does your lilo.conf look like
- you only need one lilo.conf
- simply disconnecting hda should allow you to boot
off hdc without having to touch/type anything
important lines in the lilo.conf file
what is the partition type of the disk
fdisk -l /dev/hda
fdisk -l /dev/hdc
== do NOT use disks on the same ide cable in raid1 for booting
- some bios doesnt see the hdb if hda is missing
-- if you are booting of hde/hdg...
temporarily move it to hda and hdc for simple testing of lilo
- some bios doesnt boot from disks not connected to
the ide0/ide1 ports on the motherboard
