Yes, this can be done. The trick is you need to tell lilo to install itself on hdb, boot the kernel on hdb, but pretend that everything is hda. The best way to do this is; mount /dev/hdb1 /mnt lilo -r /mnt -b /dev/hdb1 -M /dev/hdb where /dev/hdb1 is the hdb root partition, and you want to use a normal mbr with lilo installed in the boot record of that root partition. > Again, it seems like the bios= option is not relevant, because it really > will be /dev/hda. > > What is the most appropriate mailing list for lilo discussion? > > Can grub do what I want? Grub would make things a little simpler, because it delays any sort of locating of kernel etc on the disk untill boot time. It can do this because it is a whole little OS of its own that understands filesystems. Personally I find grub overkill. -- ---------------------------------------------------------------------- ABO: finger [EMAIL PROTECTED] for more info, including pgp key ----------------------------------------------------------------------
