7.4.3 When to Use Extended Translation

With MS-DOS 5.0 and Above

NetWare 386 (versions 3.0 and above) and the versions of UNIX do not share the
1024 cylinder limit of DOS and do not require extended translation to support
large disk drives and should not be enabled.

Drives With Mixed Partitions

Use standard translation, not extended translation, on drives formatted with two
or more partitions for different operating systems. Partitions for UNIX and
NetWare can be larger than 1 GByte when using standard translation.
The term UNIX, as used here, includes all
versions of UNIX, SCO OpenServer Release
5.0, and ISC v3.0 (or later).

Using Fdisk

To install a new disk, or to re-partition an existing disk, use the fdisk DOS utility
as you normally would. The cylinder size increases to 8 MBytes when you enable
extended translation. The size of the partition you request must therefore be a
multiple of 8 MBytes. If you request a partition size that is not a multiple of 8
MBytes, fdisk rounds up to the nearest whole multiple of 8 MBytes.

Questions and Answers About Extended Translation

What happens if I enable extended translation with SCSI drives that are less than
1 GByte in capacity?
Drives handled by the BIOS use extended translation if their formatted capacity is
greater than 1 GByte. Drives with less than 1 GByte of formatted capacity use
standard translation regardless of whether extended translation is enabled.
