Chapter 1 Specification
This series of mainboards features an integration of the powerful
processor Intel Pentium 4 and the single-chip North Bridge VIA Apollo
P4X400 plus South Bridge VT8235, by which the whole system perfor-
mance can be upgraded to 533 MHz system bus.
The Intel P4 processor is a rapid execution engine providing 4X100/
4X133MHz quadpumped system bus to allow 3.2GB data transfer rates
possible, while VIA Apollo P4X400 plus VT8235 supports Intel P4 pro-
cessor to implement the 4X133 Front Side Bus, AGP 8X external bus,
the LPC Super I/O, the DDR SDRAM and UATA 133/100/66 data trans-
fer rate. This chapter is to introduce to users every advanced function
of this high performance integration.

Chapter 2 Hardware Setup
1. We recommend to install your CPU before any other components.
For detailed installation instructions of processor, you can also refer
to the pamphlet enclosed in your CPU package.
2. Installing a cooling fan with a good heatsink is a must for proper heat
dissipation for your CPU. Get ready an appropriate fan with heatsink
for proper installation. Improper fan and installation will damage your
CPU.
3. In case CPU Vcore, CPU clock or Frequency Ratio is adjustable on
board, please follow the instructions described in the User Manual
for proper setup. Incorrect setting will cause damage to your CPU.

2-1 CPU I stallatio with Socket 478B
This series is built with CPU Socket 478B ( 478-pin) supporting the
Intel Pentium 4 CPU:
• Follow the steps described in this section to install the 478-pin Pen-
tium 4 CPU into the on board Socket 478.
• After installation of Pentium 4 CPU, you must also install the specific
Pentium 4 CPU fan designed in tandem with this CPU. This CPU
Fan installation is described in next section.
1. First pull sideways the lever of
Socket 478, and then turn it up
900 so as to raise the upper layer
of the socket from the lower
platform.
3. Make sure that all CPU pins have
completely entered the socket
and then lower down the lever
to lock up CPU to socket.
2. Configure Pin 1 of CPU to Pin 1
of the Socket, just as the way
shown in the diagram on the
right. Adjust the position of CPU
until you can feel all CPU pins
get into the socket with ease.

• This series supports up to 3GB unbuffered DDR 333/266/200 SDRAM,
with 3 DDR DIMM slots on board. Do not insert other type of modules
into these slots.
• DDR DIMM slot has 184-pins and one notch. Insert a DDR SDRAM
vertically into the 184-pin slot with the notch-to-rib matching. Press
the Module down in a gradual way until it surely reaches the bottom
and clicks straight up the two latches on the left and right of the slot.
If any one of the latches has not turned up completely, you should
unplug the module and press it down a bit more firmly.
How to tackle with the memory Modules:
• Make sure to unplug your power supply before adding or removing
memory module. Failure to do so may cause severe damage to both
your mainboard and the memory module.
• Pay attention to the orientation of the DIMM slots. Forcing a DIMM
into a slot improperly will damage the memory module and slot itself.
• Make sure you have the right type of memory module for your
mainboard.

The AGP slot on board supports 1.5V AGP4X/8X card only. A Rib is
specifically added to the 4X/8X AGP slot so as to match the AGP 4X/8X
card. To insert a 3.3V AGP 2X card into the AGP 4X slot will damage
the system chip and burn the 1.5V circuitry.

To install IDE Connector, you may connect the blue connector of IDE
cable to the primary (IDE1) or secondary(IDE2) connector on board,
and then connect the gray connector to your slave device and the black
connector to your master device. If you install two hard disks, you must
configure the second drive to Slave mode by setting its jumpers correctly.
Please refer to your hard disk documentation for the jumper settings.

1. Connect the on-board Main Power Connector (20-pin) to the Main
Power Connector (20-pin) of an ATX Power Supply which can be
either of the latest version 2.03 or of earlier ATX format.
2. If you use an ATX Power Supply Version 2.03 or later, you can now
connect the on-board square-shaped +12V Connector to the square-
shaped +12V Connector of your ATX Power Supply. In this case, it is
not necessary for you to connect the on-board 4-pin Peripheral Power
Connector to your Power Supply.
3. If you use an ATX power Supply of an older version than V2.03, you
cannot find a square-shaped +12V Connector with your Power Supply;
you must then connect the on-board 4-pin Peripheral Power
Connector to the 4-pin Peripheral Power Connector of your Power
Supply.

Chapter 2 Hardware Setup
Jp1 designed on board for CPU clock select and 100MHz CPU
overclocking. With Jp1, user can choose the way for a 100MHz CPU to
run an overclock on board.
2-8.1 Jp1: CPU Clock/Overclock Select
1. If Jp1 is set to 1-2 closed, the auto-detect
mode will recognize the CPU clock
automatically and send the signal to system
chips. No overclocking will be implimented
in this case. That is, a 100MHz CPU will boot
system with 100MHz CPU clock and provide
4X100 MHz system bus. A 133MHz CPU will
boot system with 133MHz and provide a
4X133 MHz system bus.
2. If Jp1 is set to 2-3 closed, CPU is set at
100MHz, indicating that 133MHz overclock
is not desired. The CPU will boot system with
100MHz even if a 133MHz CPU is used.
3. If Jp1 is set to 1-2-3 all open, CPU is set at
133MHz, indicating that 133MHz overclock
is desired. The CPU will try to boot system
with 133MHz even if a 100MHz CPU is used.

If a pin-header (of 2 or more pins) is
designed in such a way that its pins
can be closed or linked together to
set up a specific function, this header
is called a jumper in this manual.
A 3-pin Jumper
A 2-pin Jumper cap to link
two header-pins together.
• A Jumper is usually but not necessarily given a JpX legend.
Jp X
• Do not remove the jumper cap when power is on. Always
make sure the power is off before changing any jumper settings.
Otherwise, mainboard could be damaged.
How to tackle the Jumpers:
• In the Jumper setting diagram, all jumper pins covered with
black marks stand for closed pins by jumper caps.
