Disk Manager versions 3.x are compatible with MS-DOS versions 3.x.
Therefore, the same partitioning limitations apply--that is, Disk Manager
versions 3.x support a maximum of 32 MB for an MS-DOS
Disk Manager versions 4.x are compatible with MS-DOS versions 5.0 and
earlier. If you use the /4 switch when invoking Disk Manager, it can create
partitions up to the limitations of DOS 4.0x--that is, the BIOS limitation
of 1024 cylinders by 256 heads by 63 sectors per track maximum. This
partitioning scheme is also compatible with MS-DOS 5.0.
Disk Manager also creates non-DOS partitions for use in working around
the 3.x 32 MB logical drive limit. Disk Manager can also be used to to
support a hard drive type that is not supported by the BIOS. This
commonly occurs with the following configurations:
• A hard drive with more than 1024 cylinders, 63 sectors per track,
or 255 heads
• An XT system with a hard drive larger than 20 MB
If Disk Manager is being used to support a drive not supported by the
BIOS, deleting the partition will disable Disk Manager's support and
reduce the usable hard drive space.
