CPU
Supports Intel® Socket 478 Pentium® 4 (Willamette / Northwood) 1.4GHz~2.4GHz+ with 533MHz Front Side Bus (FSB) designed for Socket
478 technology.
Chipset
The motherboard is equipped with SIS 648 chipset. SIS 648 Host & Memory & AGP Controller integrates a high performance host interface
for Intel Pentium 4 processor, a high performance memory controller, a AGP interface. The SIS 648 Host Interface supports Intel Pentium
4 Series processors with FSB up to 133MHz. The host interface plays the role of processor transactions’ dispatcher. It dispatches
transactions to Memory, I/O interface and AGP bus. Transactions to different destinations can be dispatched concurrently in order to
maximum pipeline efficiency. The Memory controller can support both DDR and SDR. The memory controller also supports the Suspend
to RAM function by retaining the CKE# pins asserted in ACPI S3 state in which only AUX source deliver power. The AGP interface can
support external AGP slot with AGP 2X/4X/8X capability and Fast Write Transactions.
Expansion Slots
Including six 32-bit/33MHz PCI, one CNR and one AGP 2X/4X/8X slots. The PCI local bus throughput can be up to 132MB/s. The
Communication & Nectworking Riser (CNR)
The Accelerated Graphics Port (AGP)
support data transfer rate up to 2112MB/s. Of six PCI slots provided, all of them are master PCI slots with arbitration and decoding for all
integrated functions and LPC bus.

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 notice that some of the functions are marked as
“User Upgrade Optional” or “Manufacture Upgrade Optional”. Although all of AOpen’s motherboards have included many amazing and
powerful features, sometimes not every user is familiar with these powerful features. As a result of this we define features that can be
upgraded by users as “User Upgrade Optional”. You can upgrade these functions by purchasing additional devices. As for functions that
cannot be upgraded by users, we define them as “Manufacture Upgrade Optional”. If need be, you can contact our local distributors or
resellers to purchase “Manufacture Upgrade Optional” components, and again you are also welcome to visit our official website at
www.aopen.com
for detail information.

it into CPU socket.
1. Pull up the CPU socket lever and
up to 90-degree angle.
2. Locate Pin 1 in the socket and look for mark on the CPU upper interface.
Match Pin 1 and cut edge, then insert the CPU into the socket.
Note: Those pictures are for example only; they may not look the same with the motherboard you purchased.

AOpen provides a special and useful feature on this motherboard for overclockers. When you
power-on the system, the BIOS will check last system POST
enable “Watch Dog Timer” function immediately, and set the CPU FSB
settings stored in the BIOS. If system failed in BIOS POST, the “Watch Dog ABS” 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.

Warning: SIS 648 chipset supports maximum 400MHz
(100MHz*4) / 533MHz (133MHz*4) system bus and
66MHz AGP clock; higher clock setting may cause
serious system damage.

Note: Since the latest processor, Northwood,
would detect the clock ratio automatically,
you may not be able to adjust the clock ratio
in BIOS manually.

This motherboard provides PS2 keyboard / mouse wake-up function. You can use JP28 to enable or disable this function, which could
resume your system from suspend mode with keyboard or mouse. The factory default setting is set to “Disable”(1-2), and you may enable
this function by setting the jumper to 2-3.

This motherboard supports all DDR200/266/333 DDR SDRAM on market, therefore you don’t need to adjust this JP29 memory voltage
jumper from its default setting. However, if you wish to use DDR400 SDRAM which requires higher voltage on this motherboard, you may
have to adjust the jumper to pin1-2 for a higher voltage supply up to 2.7V.
