When installing a hard disk drive, be sure to consult the

drive type table for the drive type parameters (geometry)

which fit the drive you are installing. You can also select a

When installing a copy-protected software package, first try

the installation at high speed. If this does not work properly,

try switching to low speed for the installation If you are still

unable to load the program at high speed, try loading at low

speed and then switching to high speed.

For the Equity 486DX2/50 PLUS, high speed is 50 MHz.

For the Equity 48&3X/25 PLUS, high speed is 25 MHz.

Both systems simulate 8 MHz at low speed.

When using a software package that uses a key disk as its

copy-protection method, try loading it at high speed. If this

does not work, enable Auto Speed in Setup on the Reference

diskette.

Power-on Password

Make sure that you do not forget the Power-on password

you set up. If you do, it wilI be necessary to disable it by

moving jumper JP5 on the main circuit board to position B.
