Line 285:

A parallel development in MS-DOS / PC&nbsp;DOS which allowed an increase in the maximum possible FAT size was the introduction of multiple FAT partitions on a hard disk. To allow the use of more FAT partitions in a compatible way, a new partition type was introduced in PC&nbsp;DOS&nbsp;3.2 (1986), the ''[[Extended boot record|extended partition]]'' (EBR),<ref name="Duncan_1988_MS-DOS_Encyclopedia" /> which is a container for an additional partition called ''logical drive''. Since PC&nbsp;DOS&nbsp;3.3 (April 1987), there is another, optional extended partition containing the next ''logical drive'', and so on. The [[Master Boot Record|MBR]] of a hard disk can either define up to four primary partitions, or an extended partition in addition to up to three primary partitions.
