To display the current CPU speed, type ES P E ED only and press Enter. You see the following:

<+> : Speed Up

16.0MHz <-> : Speed Down <Esc> : Exit

To change the speed when you see this display, press the + or - key; then press Esc to exit.

The processor speed you set remains in effect until you change it using the ESPEED program again, a keyboard command, or the SETUP program; or until you press the RESET button or turn off the computer.

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 SLOWDOWN which requires a slower processor speed, you could include the following commands in a batch file to start the SLOWDOWN program:

ESPEED L

SLOWDOWN

You could name the batch file SLOW.BAT. Whenever you need to run the SLOWDOWN program, insert the program diskette in drive A. Then type S LOW and press Enter. The computer changes the speed to low and starts the SLOWDOWN program.

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