expand the external cache to 512KB or 1MB with 64K x 8 or
128K x 8, 3.3 volt, 15ns SRAM DIP chips.
You must install chips in one of the configurations in the
table below (each bank contains four cache memory sockets).
Use only 3.3 volt cache SRAM chips made by Alliance
Semiconductor.

Processor Upgrades
You can upgrade your processor with a faster one to improve
system performance. If you upgrade the processor in the
tower computer, you may want to lay the computer on its
side to make the installation process easier. If you are
upgrading to another processor, make sure you use a
standard 3.3 V processor.
Hard Disk Drive Information
The IDE hard disk drives listed in the tables below are
qualified for use in the computer.

disk drive parameters
Hard Disk Drive Types
The computer comes with a hard disk auto-sensing feature.
To use it, select one of the drives you have installed from the
Fixed Disk Setup screen On the screen that appears for that
drive, press Enter to select the Autotype Fixed Disk
option. The system detects the type of hard disk drive, fills in
the drive’s parameters, and sets the remaining options on the
screen.

Installation/Support Tips
Installing Diskette Drives
0
Make sure that the drive type has been correctly selected
in the SETUP program.
0
Make sure jumper JP4 is set to position 1-2 to enable the
diskette drive controller.
Installing Hard Disk Drives
If you are installing a drive that cannot use the embedded
IDE interface (such as an ESDI drive), it is recommended
that you use a 16-bit, AT-type hard disk controller or, for
higher performance, a PCI hard disk controller. If you
install a non-IDE hard disk drive and controller card, you
must set jumper JP13 to on to disable the built-in IDE hard
disk drive interface. Also, remove the hard disk drive
ribbon connector from the system board.
When installing an IDE hard disk drive, use the
auto-sensing feature in SETUP to select the correct type
for the drive. If the auto-sensing feature does not produce
a match for the drive, you can define your own drive type
by selecting User
parameters.
Installing Option Cards
If you are installing a video adapter card, make sure you
disable the built-in VGA controller by setting jumper JP2
to 2-3.
Installing SIMMs
Make sure you check jumpers JP12 and JP14 and change the
settings if necessary when you install SIMMs.
Booting Sequence
If you cannot boot the computer from the hard disk, make
sure the booting sequence in SETUP is set to
Then boot the computer from a system diskette in drive A.
as the type and entering the drive’s
A: then C:.
Password
If you forget your password, you must discharge your
CMOS memory as follows:
1.
Turn off the computer and remove the cover.
2. Disable the password by setting jumper JP6 on the main
system board to on.
3.
Turn the computer on, leave it on for a few seconds, then
turn it off again.
4.
Set jumper JP6 back to off to select the system board battery.
5.
Run SETUP to enter a new password, if desired.
