Changing the Processor Speed
In MS-DOS, your computer's processor can operate at two
speeds: fast (the highest speed of the processor) and slow
(8 MHz). At fast speed, the computer performs all tasks faster.
The slow speed is available for compatibility with some older
programs or copy-protected programs that have specific timing
requirements.
Some of these programs require you to leave a key disk—the
diskette that contains the copy protection—in the diskette
drive. To use a copy-protected program, you can change the
speed to slow to access the diskette and return it to fast speed
when you are finished.
From MS-DOS, you can change the processor speed
temporarily by entering one of the following commands from
the numeric keypad on your keyboard:
To select slow speed, press
off and the system beeps once.
To select fast speed, press
on and the system beeps twice.
Note
You can use the commands listed above while you are
running a program. However, if the program uses one of
these commands for another function, you cannot use it to
change the processor speed.
The speed setting remains in effect until you reset your
computer or turn it off.
