speed

The message tells you the switches you should use to set the speed to high, low, or automatic speed. At the MS-DOS prompt, type the E-SPEED command again and include the appropriate switch, such as the following:

ESPEED /A

This command sets the processor speed to change to low speed automatically when the computer accesses a diskette.

If you include the switch when you type the initial ESPEED command, the program changes the speed without displaying the Speed Control Utility message.

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, another 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 an 8 MHz processor speed when the program is running on a diskette, you could include the following commands in a batch file to start the SAMPLE program:

ESPEED /A
