lnstallation / Support Tips

Power

This computer has an automatic input voltage sensing power

supply (between 

 for USA and Canadian use, and 

 for

use in other countries). There is no manual switch

Mouse and Keyboard

When connecting the mouse and keyboard, be careful to

plug them into the 

 ports. Although they are

physically identical, they are not interchangeable, and

damage may occur to the ports or the 

 board.

Installing Floppy Disk Drives

When installing a floppy disk drive as drive B, remember to

set the drive select jumper to the second position and attach

the pass-through connector on the floppy drive controller

cable to the drive, not to the end connector.
If the drive does not function normally, make sure that the

drive type has been correctly selected in Setup. Also check

that any necessary drivers have been installed correctly.
If you have installed two floppy disk drives, remember that

the computer will boot 

 drive B when a disk is inserted

Installing Hard Disk Drives

It is recommended that a 

 AT-type hard disk

controller be used if you are installing a drive that cannot

use the embedded IDE interface. lnstalling a 16-bit interface

 override the embedded IDE port and disable it, 

the standard base l/O 

 and 

Setup

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

type with parameters having lesser values, as long as they

do not exceed the maximum capacity (in MB) of your drive.

 there is no match for your drive, enter the 

parameters using the User 

 option.

Software Problems

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 

 PLUS, high speed is   MHz.

For the Equity 

 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 

 be necessary to disable it by

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