These choke if you don't have a valid > MBR. MBR's are part of the i386 defacto architecture, deal. Don't these BIOSs have fallbacks for the case where there's no DOS-style MBR partition table? The PC BIOS copes with it for IDE disks using the disk type stuff or whatever; it should be no different for a SCSI BIOS. As I said, if that's broken and you *really* need the MBR partitioning table as a crutch, it's important not to force that to affect the user- visible partition labelling scheme for the common case of one BSD disklabel per disk.
