See your MS-DOS Reference Manual for instructions on
creating and using batch files.

If your system has two diskette drives, they are connected inside

your computer so that the top drive is A and the bottom drive is

B. Because drive A is the “boot” drive, whenever you want to
load the operating system or a bootable program from a diskette,

you must insert the diskette into drive A.

If both of your drives are the same type–5¼-inch, 1.2MB

capacity, for example-you never need to reassign the drives. If
your two drives are different types, however, you may need to

change the drive letter assignments so you can boot the
computer from drive B. For example, you may have a 3½-inch
program disk which you need to use to boot the computer. Or
you may have an application program that requires you to leave
the 3½-inch key disk in drive A while you run the program.

For these situations, you can reverse the drive assignments to
make the top drive B and the bottom drive A. There are two
ways to do this:

❏ Insert the diskette in the drive you want to boot from and

turn on the computer. The drive automatically becomes

drive A.

❏ Run the AFDD program to reassign the drive. See “Using

the AFDD Program,” below, for instructions.

Your assignments remain in effect until you press the RESET

button or turn off the computer, or until you reassign the drives

to their original assignments. The reassignment remains in effect

if you reset the computer from your hard disk by entering the

Ctrl Alt Del 

command.
