Epson EQUITY 386SX/16 PLUS - Manual (Page 75)

There are different types of copy-protected programs.
Depending on the type you have, you may or may not want
to set the processor to automatic speed. Follow these
guidelines:
If you are using a copy-protected program that can run
only on a diskette or that requires a key disk, try to start
the program on high speed. If this works, you do not
need to set the speed to change automatically. If you
can’t load the program on high, set the speed to change
automatically.
If you are using a copy-protected program that does not
require a key disk but requires a special procedure to
install the program on a hard disk, set the speed to low
while you are installing the program. Once it is installed,
set the speed to high, where you should be able to leave
it while you load and run the program.
If this does not work, try installing
and loading the
program at low speed and then change to high speed to
run it. Do not set the speed to change automatically.
There are three ways to change the processor speed:
Run the SETUP program
Enter a keyboard command
Run the ESPEED program.
If you frequently use programs that require the processor to
operate at low speed or require the automatic speed change
when your computer is accessing a diskette, use SETUP to
change the processor speed. See Chapter 2 for instructions.
If you use these programs only occasionally, you should use
the keyboard commands or the ESPEED program (described
below) to change the processor speed.
