Additional Utilities
The Reference diskette contains the following additional utilities:
ESPEED
HDSIT.
Changing the Processor Speed
The computer’s processor can operate at two speeds: high or low. High speed is the highest
speed at which the microprocessor is capable of running. Low speed simulates an 8 MHz
processor to provide compatibility with older application programs.
You can also set the computer to automatic speed which switches your computer’s processor
from high to low speed when it accesses a diskette drive.
Note When your computer is operating at high speed, the power light on the front panel is
green. It is amber when the computer is operating at low speed.
There are three ways to change the processor speed:
Run the SETUP program
Enter a keyboard command
Run the ESPEED program.
The ESPEED program is useful in batch files that start applications that have key functions
that conflict with the keyboard commands. To use the program at the
DOS
prompt, type
ESPEBD
option
and press
Enter.
Table B-7 lists the options.

ESPEED Command Options
Preparing the Hard Disk for Moving
If you need to move the computer to a new location, you may want to run the HDSIT
program provided on the Reference diskette to protect the hard disk during the move. This
program is not necessary on IDE drives as long as you do not move the system for
20 seconds after turning the power off. IDE drives automatically park the heads.
