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

controller be used if you are installing a drive that cannot
use the embedded IDE interface. lnstalling a 16-bit interface

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

For the Equity PLUS, high speed is 25 MHz.

copy-protection method, try loading it at high speed. If this
does not work, enable Auto Speed in Setup on the Reference
diskette.
