Using the AFDD Program
AFDD reverses the current diskette drive assignments and
resets the system. When you are done using the reversed drive
assignments, you can use the AFDD program again to reassign
the drives to their original configuration.
The AFDD program is provided with your system on the
Reference diskette. If you do not have a hard disk, insert your
Reference diskette in drive A and log onto drive A before you
enter the command to start the program.
If you have a hard disk drive, copy the file AFDD.EXE from the
Reference diskette onto your hard disk (if you have not already
done so); then you can run the program from there.
To run AFDD, type the following at the command prompt and
press
AFDD
You see messages such as the following:
New Assign Present
Drive A: 1.44MB <= 1.2MB
Drive B: 1.2MB <= 1.44MB
(S)et and Reboot, Any other key to abort ?
If you inserted the Reference diskette to run AFDD, remove it
now.
If you want to change the drive assignments, press The
system reboots and loads the operating system, and the new
drive assignments take effect. If you do not want to change the
drive assignments, press any other key.
