Purpose: Used in the CONFIG.SYS file to set parameters for a disk drive.


Used for special configurations related to disk drives.


/D:num - Specifies the physical drive number (0 to 255, where drive A=0, drive B=1, etc.)
/C - Speeds up access to the floppy drive by signally to DOS that the media in a drive may have been changed.
/F:type - Specifies the type of drive being accessed. The following types can be specified:

0 Double-density 360K, 5 1/4-inch floppy disk drives (includes 160K, 180K, 320K and 350K formatted media size.
1 High-density, 1.2M, 5 1/4-inch floppy disk drives.
2 Double-density, 720K, 3 1/2-inch floppy disk drives.
5 Hard disk drives.
6 Tape drives.
7 High-density, 1.44M, 3 1/2-inch floppy disk drives.
8 Read-write optical disk drives.
9 Super-high-density, 2.88M, 3 1/2-inch floppy disk drives.

With DOS Version 6, type 3 (single-density 8-inch floppy disk drives) and type 4 (double-density 8-inch floppy disk drives) are no longer supported.

/H:heads - Specifies the number (1 to 99) of read/write heads on the disk drive.

/I - Tells DOS that a 3 1/2-inch disk drive, not supported by the ROM BIOS, is attached to a standard floppy disk drive controller.

/N - Tells DOS that the drive uses nonremovable media.

/S:sectors - Specifies the number (1 to 99) of sectors per track for the drive`s media.

/T:tracks - Specifies the number of tracks per side for the drive`s media.
