support 400/533/800 MHz FSB; AX4SP-G and AX4SP-GN only support 400/533 MHz FSB.
Chipset
Intel 865-P/PE is a Memory Controller Hub (MCH) designed for use with the Pentium 4 processor with 512-KB L2 cache on 0.13
micron processor. The MCH provides CPU, DDR, AGP, Hub, and CSA Interfaces. The CPU interface supports Pentium 4
processor subset of the Extended Mode of the Scalable Bus Protocol. The MCH memory interface supports one up to two
channels of DDR, and the AGP interface supports 0.8V/1.5V signaling with 8X/4X data transfers and 8X/4X AGP Fast Writes.
The 865-P/PE platform supports the fifth generation I/O Controller Hub.
The ICH5 integrates an Ultra ATA 100 controller, two Serial ATA host controllers, one EHCI host controller and four UHCI host
controllers supporting eight external USB 2.0 ports, LPC interface controller; flash BIOS interface controller, PCI interface
controller, AC’97 digital controller, an ASF controller and a hub interface for communication with the 865-P/PE MCH.

This chapter describes jumpers, connectors and hardware devices of this motherboard.
Note: Electrostatic discharge (ESD) can damage your processor, disk drives, expansion boards, and other
components. Always observe the following precautions before you install a system component.
1. Do not remove a component from its protective packaging until you are ready to install it.
2. Wear a wrist ground strap and attach it to a metal part of the system unit before handling a component. If
a wrist strap is not available, maintain contact with the system unit throughout any procedure requiring
ESD protection.

When you read this online manual and start to assemble your computer system, you may find some of functions are called “Manufacturer
Upgrade Optional”, and some are called “User Upgrade Optional”. Though all AOpen motherboards include many amazing and powerful
features, in some situations, these powerful features are not used to every user. Hence, we changed some key features as “Manufacturer
Upgrade Optional” for you to choose. Some optional functions that can be upgraded by users, we call them “User Upgrade Optional”. As for
those optional functions that can’t be upgraded by ourselves, we call them “Manufacturer Upgrade Optional”. If needed, you can contact our
local distributors or resellers for purchasing “User Upgrade Optional” components, and again you can visit AOpen official web site:

2. Remove ATX power cable from connector PWR2.
3. Locate JP14 and short pins 2-3 for a few seconds.
4. Return JP14 to its normal setting by shorting pins 1 & pin2.
5. Connect ATX power cable back to connector PWR2.

This motherboard supports Intel® Pentium 4 Socket 478 series CPU. Be careful of CPU orientation when you plug it into CPU socket.
1. Pull up the CPU socket lever and
up to 90-degree angle.
Note: These pictures are for example only; it may not exactly be the same motherboard.
2. Locate Pin 1 in the socket and look for a cut edge on the CPU upper
interface. Match Pin 1 and cut edge, then insert the CPU into the socket.

CPU VID signal and SMbus clock generator provide CPU voltage auto-detection and allows the user to set the CPU frequency through the
BIOS setup, therefore no jumpers or switches are used. The disadvantages of the Pentium based jumper-less designs are eliminated.
There will be no worry of wrong CPU voltage detection.

The Over Current Protection is a popular implementation on ATX 3.3V/5V/12V switching power supply. However, the new generation CPU
uses different voltage with a regulator to transfer 12V to CPU voltage (for example, 2.0V), and thus makes 5V over current protection
useless. This motherboard is with switching regulator onboard supporting CPU over-current protection; in conjunction with 3.3V/5V/12V
power supply provide the full line over-current protection.
ATX Switching Power Supply
Note: Although we have implemented protection circuit try to prevent any human operating mistake,
there is still certain risk that CPU, memory, HDD, add-on cards installed on this motherboard may be
damaged because of component failure, human operating error or unknown nature reason. AOpen
cannot guaranty the protection circuit will always work perfectly.

CPU FSB frequency according to user’s settings stored in the BIOS. If system failed in BIOS POST, the “Watch Dog Timer” will
reset the system to reboot in five seconds. Then, BIOS will detect the CPU’s default frequency and POST again. With this
special feature, you can easily overclock your system to get a higher system performance without removing the system housing
and save the hassle from setting the jumper to clear CMOS data when system hangs.

Tip: If your system hangs or fails to boot because of
overclocking, simply use <Home> key to restore the
default setting or you can wait the AOpen “Watch Dog
