Drivparm Ü ßßßßßßßßß Defines parameters for block devices when you start FreeDOS. 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] /D:number Specifies the physical drive number. Values for number must be 0 through 255 (for example, drive number 0 = drive A, 1 = drive B, 2 = drive C, etc...). /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«" disk) 5 Hard disk 6 Tape 7 1.44 MB (3«" disk) 8 Read/write optical disk 9 2.88 MB (3«" disk) /H:heads Specifies the maximum number of heads. Values for heads must be 1 through 99. The default value depends on the value you specify for /F:factor. /I Specifies an electronically-compatible 3« floppy disk drive. /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 1 through 99. The default value depends upon the value specified for /F:factor. /T:tracks Specifies the number of tracks per side that the block device supports. The default value for each depends upon the value specifie for /F:factor. Notes Using the /I switch Use the /I switch if your system's ROM BIOS does not support 3«" floppy disk drives. Disk drive change support Change-line support means that a physical disk drive can detect an open drive door. This lets FreeDOS know when one floppy disk has been replaced by another. The /C switch lets FreeDOS make use of change-line support. To find out if your disk drive has change-line support, see your disk-drive documentation. Example: To reconfigure a tape drive on drive D to write 10 tracks of 99 sectors each, add this command to CONFIG.SYS: drivparm=/d:3 /f:6 /h:1 /s:99 /t:10 See Also: Config.SYS
