Defines parameters for devices such as disk and tape drives when you start
MS-DOS. You can use this command only in your CONFIG.SYS file.
The DRIVPARM command modifies the parameters of an existing physical drive.
It does not create a new logical drive. The settings specified in the
DRIVPARM command override the driver definitions for any previous block
DRIVPARM=/D:number [/C] [/F:factor] [/H:heads] [/I] [/N] [/S:sectors]
Specifies the physical drive number. Values for number must be in the
range 0 through 255 (for example, drive number 0 = drive A, 1 = drive B,
2 = drive C, and so on).
Specifies that the drive can detect whether the drive door is closed.
Specifies the drive type. The following list shows the valid values for

Specifies the maximum number of heads. Values for heads must be in the

Specifies the number of sectors per track that the block device
supports. Values for sectors must be in the range 1 through 99. The

Specifies the number of tracks per side that the block device supports.
