This is interesting. Is this a necessary restriction, or just a limitation
of the current implementation? I ask because the IBM on-disk partition table
has both linear and C/S/H addresses for partitions; and the DOS file system
only uses linear addresses for on-disk structures. So I wonder what
causes this restriction?
