◄Notes► ◄Example► ──────────────────────────────────────────────────────────────────────────── DRIVPARM 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 device. Syntax DRIVPARM=/D:number [/C] [/F:factor] [/H:heads] [/I] [/N] [/S:sectors] [/T:tracks] Switches /D:number 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). /C Specifies that the drive can detect whether the drive door is closed. /F:factor Specifies the drive type. The following list shows the valid values for factor and a brief description of each. The default value is 2. 0 160K/180K or 320K/360K 1 1.2 megabyte (MB) 2 720K (3.5-inch disk) 5 Hard disk 6 Tape 7 1.44 MB (3.5-inch disk) 8 Read/write optical disk 9 2.88 MB (3.5-inch disk) /H:heads Specifies the maximum number of heads. Values for heads must be in the range 1 through 99. The default value depends upon the value you specify for /F:factor. /I Specifies an electronically compatible 3.5-inch floppy disk drive. (Electronically compatible drives are installed on your computer and use your existing floppy-disk-drive controller.) Use the /I switch if your computer's ROM BIOS does not support 3.5-inch floppy disk drives. /N Specifies a non-removable block device. /S:sectors Specifies the number of sectors per track that the block device supports. Values for sectors must be in the range 1 through 99. The default value depends upon the value you specify for /F:factor. /T:tracks Specifies the number of tracks per side that the block device supports. The default value depends upon the value you specify for /F:factor. ♦
