System default files

/etc/default/msdos

This file contains the mapping of UNIX devices to MS-DOS^® drive letters and types. It gives the user a choice of the following drives:

A: Floppy drive A
X: Another name for floppy drive A
B: Floppy drive B
Y: Another name for floppy drive B
C: undefined, or MS-DOS partition of hard disk 0 (see below)
D: MS-DOS partition of hard disk 0 or 1 (see below)

As delivered, /etc/default/msdos defines D as /dev/dsk/c0b0t0d0p1 (the first partition of hard disk 0). This definition assumes that the first entry in the fdisk(1M) partition table defines the MS-DOS partition. If the first entry in the fdisk partition table does not define the MS-DOS partition, the p1 part of the disk name will need to be changed to point to the correct entry. This information also applies to the second entry in the partition table file, if a second MS-DOS partition has been defined.

If an application expects C to be the MS-DOS partition of hard disk 0, the administrator can uncomment the line defining C and comment out the line defining D as the MS_DOS partition of hard disk 0. Further, the administrator can uncomment a line defining D as /dev/dsk/c0b0t0d0p1 if an application expects D to be the MS-DOS partition of hard disk 1. The /etc/default/msdos file will need to be modified to reflect the current configuration, that is, which /dev node(s) are currently pointing to DOS partitions.
