What is it with DOS 5 partitions anyway?  There are confirmed
problems if you use DOS 5 FDisk to change a NEC 3.3 partition,
or a Disk Manager partition (with the first, you get an occasional
"FATs don't match" message when the FATs really should; with
the second, DOS's new Mirror program won't run on any but the
C drive).  

Is DOS recording partition information differently?  Is it not
changing the old partition information?  Is it something to
do with the fact that NEC 3.3 DOS allowed >32M partitions? That
DM allowed more than 1024 cylinders on the drive?  Any ideas?
