Adaptec PC/104, PCM-3420 manual

DOS PARTITION

A section of a disk storage device, created by the DOS FDISK program, in which data and/or software programs are stored. Computers have a primary DOS partition that contains the special files needed to boot the computer. A computer’s disk devices may also have extended DOS partitions. Each DOS partition is assigned a unique drive letter, such as C or D. A single disk device can have multiple partitions. After you have installed EZ- SCSI you can use the AFDISK utility program to partition disk devices.
