To enter these commands, hold down the Ctrl key and the
Alt key and press the + or -
key on the numeric keypad. The
speed setting remains in effect until you press the RESET button
or turn off the computer, or until you change it again using the
SETUP program, another keyboard command, or the ESPEED
program, described below.
Using the ESPEED Program
The ESPEED program provides an easy way to change the
processor speed if your application program does not recognize
the Ctrl keyboard commands or if you want to include the
program command in a batch file.
The ESPEED 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 ESPEED.COM from
your Reference diskette onto your hard disk and run the program
from there.
To run the ESPEED program, type the following at the
MS-DOS command prompt and press
Enter:
