The message tells you the switches you should use to set the
speed to high or low. At the MS-DOS prompt, type the
ESPEED command again and include the appropriate switch,
such as the following:
ESPEED L
This
command changes the processor speed
to
low.
To
see
the current CPU speed,
type ESPEED
only and press
Enter. You
see the following:
<+>
: Speed Up
12.0 MHZ <->
: Speed Down
<Esc>: Exit
The processor speed you set remains in effect until you press the
RESET button or turn off the computer, or until you change it
using the SETUP program, a keyboard command, or the
ESPEED
program again.
Entering the ESPEED command in a batch file
You may want to run the ESPEED program by including the
command in a batch file. For example, if you have a program
called
SAMPLE
which requires a slower processor speed, you
could include the following commands in a batch file to start
the
SAMPLE
program:
ESPEED L
SAMPLE
You could name the batch file SAMP.BAT. Whenever you
need to run the
SAMPLE
program, insert the program diskette
in drive A. Then type
SAMP
and press
Enter.
The computer
changes the speed to low and starts the SAMPLE program.
See your MS-DOS Reference Manual for instructions on
creating and using batch files.
