When to Use Extended Translation

With DOS Version 5 Only

NetWare 386and the newer versions of UNIX do not share the 1024 cylinder limit of DOS and do not require extended transla- tion to support large disk drives. OS/2 does not currently support extended translation.

Drives With Mixed Partitions

Do not use extended translation on drives formatted with two or more partitions for different operating systems. Use standard translation. The sum of the DOS partitions will be less than 1 Gigabyte. Partitions for UNIX and NetWare can be larger than 1 Gigabyte when using standard translation.

Note

UNIX is understood to be ATT/USL all versions, SCO v3.2.4 (or later) and ISC v3.0 (or later).

Using Extended Translation

CAUTION

If you have already partitioned a large disk drive with one translation method, conversion to another method will erase your data. Be sure to back up your disk drive prior to any change in the translation method used.
