Mikkel,
He says Linux is complaining about the drive format incompatability... That
leads me to think the boot is actually happening from the scsi drive as
wished, but that lilo is loading and then trying but unable to finish
because the drive order is changed. Would this mean that if he unplugs the
ide drive ( power or data cable) and powers up he should be able to make his
needed boot disk (floppy) and then shut down, plug in again the ide drive ,
boot with the floppy and mount the scsi drive, run lilo and be where he
wants to be? Doesn't lilo check the drive configuration and put that info
into the loader part it boots with?
