┌──────────────────┐
│About the Drives: │
└──────────────────┘
The 25-1065/25-1066 and 25-1075/25-1076 combinations are specific to each
other. You can not interchange the drives and adapters.

Before installing the 3½" drive in the disk drive adapter, it must be
configured as the correct drive you want it to be (Drive A or Drive B).
Located at the rear, right side of the floppy drive is a four position
sliding switch. This switch will determine the drive designation, the
positions are listed below:

                  D C B A
                ┌─────────┐
                │     █   │
                └─────────┘

The switch is shown in the drive B: position, this is the most common
setting for the floppy drive. The original 5¼" drive is already drive A:.

┌────────────────────────┐
│The DRIVPARM Statement: │
└────────────────────────┘

The command "DRIVPARM=/D:n /F:x" must be added to a CONFIG.SYS file
(n specifies the logical drive number of the drive, Drive A=0,Drive B=1)
(x specifies the format of the drive, 2 = 720K bytes 3½"disk)
Refer to an MS-DOS reference manual for more information about using the
DRIVPARM statement.

Example for Drive B:

         DRIVPARM=/D:1 /F:2
