The other port that uses MBR partitions, NetBSD/powerpc, uses the "absolute" approach (no "slices" of any sort); if a NetBSD disklabel is found, its partition information is used, else the information from the MBR is used. The MBR and the NetBSD disklabel must be consistent for partitions that both OpenFirmware and NetBSD share (such as the FAT where the boot program is loaded from). Jason R.
