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  This lets FreeDOS know when one floppy disk has been
 replaced by another.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
