Good for things like OS/2.

You might have used OS/2's version of FDISK. In there, you can use the
OS/2 Disk Manager to boot up to four primary partitions which can be made on
the same physical disk.

In DOS 6.0 onwards, you can setup multiple configurations when you start
your computer. Basically, you have "blocks" of statements for each
configuration in your CONFIG.SYS, and MS-DOS asks you to press a number
corresponding to which block of statements you want to execute in your
CONFIG.SYS and AUTOEXEC.BAT. Type "help config.sys" as the DOS prompt
for more information.
This is probably not what you are talking about, however.

I do know for a fact that you cannot set up more than one primary
partition on a single physical disk using MS-DOS FDisk.

Take Care.
