The BIOS should be set to boot from ALL drives of the mirror, it tries booting from each drive, if one has fails it moves on to the next. The only edge case this fails is if a drive has a valid bootloader in the MBR but has a missing/corrupt OS. If the drive has no bootloader (like a non-boot data drive) it is safe to have in your boot order. Clear the MBR on all drives during OS install (zerombr in Kickstart). So in general you can put all your drives in the BIOS boot order, some BIOS have a single selection like "SCSI ALL" for this. -Anton
