card should always be set to position B. The 486DX2/66 card
has no jumpers. Set the jumpers on the 486DX/33 card
according to the table below.

OverDrive Modules

If you have the 486SX/25 or 486DX/33 CPU card, you can
install an Intel OverDrive module on the card to effectively
double the internal clock speed of the computer’s
microprocessor. Although there is an OverDrive socket on
the 486DX2/66 card, there is no OverDrive module available
for it at this time.

Available OverDrive Modules

CPU card

If you install this module, you cannot also install a 4875X/25
microprocessor chip because both options require the same socket

SIMM Installation

There are two SIMM sockets on the main system board, next

to the option slots. You can install 36-bit, fast-page mode
SIMMs that operate at an access speed of 70ns or faster, with
a capacity of lMB, 4MB, 16MB, or 64MB.

The following table shows the possible SIMM configurations;
do not install memory in any other configuration. Make sure
that both SIMMs operate at the same speed. There is 4MB of

memory soldered onto the main system board.

SIMM Configurations

Hard Disk Drive Types

The following table lists the types of hard disk drives you can
use in the computer. Check this table and the documentation
supplied with your hard disk to find the correct number for
the type of hard disk drive(s) installed in your computer. You
need to enter this number when you set the hard disk drive
configuration in the SETUP program.

Installation/Support Tips

Power

This computer has an automatic input voltage sensing power
supply (between 115V, for USA and Canadian use, and 230V,
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 proper ports. Although they are
physically identical, they are not interchangeable, and
damage may occur to the ports or the main board.

Installing Diskette Drives

When installing a third-party diskette drive as drive B,
you may need 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.

Installing Hard Disk Drives

It is recommended that a 16-bit, AT-type hard disk

controller be used if you are installing a drive that cannot

use the embedded IDE interface. Installing a 16-bit

interface will override the embedded IDE port and disable

it, freeing the standard base I/O address and IRQ(s).

SETUP

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.

Power-on Password

Make sure that you do not forget the Power-on password
you set up. If you do, it will be necessary to disable it by
moving jumper JP6 on the main circuit board to position A.

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. If there is no match for your drive, enter the exect

parameters using the User Defined 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 theinstallation. If
you are still unable to load the program at high speed, try

loading at low speed and then switching to high speed.

Processor speed varies depending on the CPU card

installed. For the 486SX/25, high speed is 25 MHz; for the

486DX/33, high speed is 33 MHz; and for the 486DX2/66

card, high speed is 66 MHz. All systems simulate 8 MHz

at low speed.
