Epson 20 - Manual (Page 37)

When Auto speed is enabled, your computer automatically switches
to 8 MHz whenever it needs to access a diskette drive. It runs at
20 MHz for all other operations.
There are different types of copy-protected programs, and depending
on the type you have, you may or may not want to enable the Auto
speed function. Follow these guidelines:
l
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 at
20 MHz. If this works, you do not need to enable the Auto speed
function. If you can’t load the program at 20 MHz, enable Auto
speed.
l
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 the hard disk, set the speed switch on the front panel to
8 MHz while you are installing the program. Once it is installed,
set the switch to 20 MHz, where you should be able to leave it
while you load and run the program. If this does not work, try
loading the program at 8 MHz and then switch to 20 MHz to use
it. Do not use Auto speed.
