Step 6. Install the Internal Peripherals
The internal peripherals meansdevicesthat in the computer
chassis like the Floppy Disk Drive, HardDisk Drive, CD ROM
Drive …etc. With this motherboard package, there are 34, 40,
50 and 68(P55XUW only) pin flat cable. Use these cablesto
connect the motherboard a nd interna l devices. All flat cable’s
connectorhousing have the key protect,this will guide you the
correct direction when you insert.

Step 7. Install the External Peripherals
The externaldevice meansdevicesthat outsidethe computer
chassis like the Serial mouse,Printer, PS/2 Mouse, External
Modem…etc.
Step 8. Install the Reset switch
Most computerchassis provides a reset switch to front pannel
control. Use thechassis provides a 2 pin housing and connect
to this reset switch(any direction can function this). This will
provides the system a hardwarereset once thesystem was hang.

Step 10. Install the Keylock
Most computerchassis will provides a keylock switch.
Normally connect the marked keylock connectorto the
motherboard keylock.This will cause the keyboard out of
function once you switch the keylock to “Lock”. This will
prevent any un-authorized keyin.
Step 11. Install the Speaker
Connect the speaker to the motherboard’s speaker connector.
(normally the red cableis +5V power) Or follow the Chapter-0
Quick Installation Step 2, if you use the original manufacture
provides CPU cooler or reference to theCPU Cooler’s operation manual)
Step 12. Install the Power LED
Some computerchassis provides a power LED for identify if
the system is on or off. Connect the power LED to the
motherboard’s TB LED connector. (normally the red ca ble is
+5V power)

(normally the red cableis +5V power)
Step 14. Install the Power Input
This SCSI motherboard providesan ATX power input. A set
20 pin connector for motherboard’s power input. Once the ATX
power was placed on this system, the JP25(front panelpower
on/off switch) is necessory to be connected.
Step 15. Install the Keyboard

14
Follow the keyboard cable’s key direction and connect to this
motherboard.
Step 16. Install the Display Card
Finally, follow the display card you have and insert in
horizontaldirection into the PCI/ISA expansion slot.
Step 17. Power on the system
Once the system was power on, on the lower left corner of the
screen will show ”Press DEL to enter SETUP, ESC to skip
memory test”. Then press “DEL” to enter BIOS setup for the
first time power on and choose the “LOAD SETUP
DEFAULTS” then BIOS will responds “Loa d SETUP
defa ult(Y/N)?”, press “Y” and “Enter”. Final choose “SAVE to
CMOS and EXIT (Y/N)?” by pressing “Y” and “Enter”.
Step 18. Enjoy this power SCSIMotherboard
After these steps of installation, thesystem should prepared
and can run most software.And you can follow the Operation
System and Application software install procedule to run.

CHAPTER1
Overview
Thank you for purchasing this P55XU/XUW SCSI Motherboard. This operation
manual will guide you to proper configure and install. It has an overview of the
engineer design and feature of this board. Also, this manual provides useful
information for your later upgrade or change the configuration. Keep this, for
your future need.
1.1 Featuress
This P55XU/XUW SCSI Motherboard is the newest ATX form factor based
memberto our SCSI Motherboard solution products families. It incorporated with
Intel 6th generation 430TX Chipset and Adaptec new PCI Ultra SCSI AIC-
7860(AHA-2940AU) / Ultra Wide SCSI AIC-7880(AHA-2940UW) that double/
fourtimes the SCSI speed. In order to support fully plug and play I/O,an Ultra I/O
that contain keyboard and real time clock is used for users to enjoy the plug and
play function. This SCSI motherboard has designed with ATX form factor to
improve the easy access memory module, long add-on card support and some of
the new featuresthat traditionalAT form factorcan not achieved.
Run with faster and use one single jumper cap to adjust the CPU speed is very
important function that this SCSI Motherboard supports. It supports P54C up to
200 MHz and Intel’s new generation P55C processor tha t support MMX
technology. Of course, the AMD K6 from 200 MHz, K5 up to 200 MHz and Cyrix
6x86L up to PR200 MHz all are supported on this SCSI motherboard. The fixed
feature on-board 512KB L2 pipelined burst cache design well prepared to run
heavy applications.
Run with faster system memory is another plus on this SCSI Motherboard to
outperform the whole system performance. It equipe 4 of the 72 pin SIMM that
support both fast page and EDO DRAM also with three of the 168 pin DIMM
memory socket that support the new synchonousDRAM.
◼CPU:
CPU socket (socket 7) supports theflexibility of different type of current
Cyrix (M1, M2), AMD (K5, K6) and futureIntel Pentium processor. One
easy jumperdesign, while choosing your CPU speed from 75 to 266MHz.
◼BIOS:

16
2 Mega bit Award BIOS, supportsbootableCD-ROM, bootableSCSI
harddisk, USB,on-screen "Plug & Play" setup for Adaptec SCSI,
Enhanced IDE, and Ultra Multi-IO. Support Flash ROM ( This ROM
provides better upgrade ability for user to updatetheir BIOS data on the
system board,user can down-load/ update newer version BIOS from
Internet or diskette file.
◼Cache memories:
High performance write-back Level 2 externalstatic RAM cache.This
supports 512KBSynchronousPipeline Burst Cache on-baord.

17
◼Memories:
4 X 72-pin SIMM(Single In Line Memory Module)
3 X 168-pin DIMM(Dual In Line Memory Module) (Rev 1.1)
Support up to 256MB (minimum of 8MB ) on board.for both the Fast
Page Mode and Extended Data Output (EDO) module.The four SIMM
modules were devided into two Banks(Bank 1 & Bank 0). There arealso
three DIMM modules were devided the three Banks(Bank 3 & Bank 1 &
Bank 0), the DIMM modules were only support for 3.3V Un-buffered.The
memory will not upgrade(memory size will not increase), if the memory
modules were inserted in the sameBank.This meansif the SIMM module
J5/J10 was firstly inserted, then it is useless while DIMM module M2 was
inserted again,because they were occupied the same memory bank.
