With biosboot the BIOS just boots the bootloader on the disk, it does not need any idea of what partitions are there. However, some BIOSes seem to be helpful and double check you have "valid partitions" - whatever that means. But in general it just works (modulo bugs with booting RAID setups, but those bugs are somewhere in our bootloader). Martin
