If you don’t want to connect to the front audio header, pins
5 & 6, 9 & 10 have to be jumpered in order to have signal
output directed to the rear audio ports. Otherwise, the
Line-Out connector on the back panel will not function.

CPU Frequency Jumpers: SW1 & SW2
These two jumpers provide 100MHz, 133MHz, 166MHz, and 200MHz  Front Side Bus
frequency selection for overclocking purpose.

The motherboard provides the following jumpers for you to set the computer’s function.
This section will explain how to change your motherboard’s function through the use
of jumpers.
Clear CMOS Jumper: JBAT1
There is a CMOS RAM on board that has a power supply from external battery to
keep the data of system configuration. With the CMOS RAM, the system can auto-
matically boot OS every time it is turned on. If you want to clear the system configuration,
se the JBAT1 (Clear CMOS Jumper ) to clear data. Follow the instructions below to
clear the data:

You can clear CMOS by shorting 2-3 pin while the system is off.  Then
return to 1-2 pin position. Avoid clearing the CMOS while the system
is on; it will damage the mainboard.

Slots
AGP (Accelerated Graphics Port) Slot
The AGP slot allows you to insert the AGP graphics card.  AGP is an interface
specification designed for the throughput demands of 3D graphics.  It introduces a
66MHz, 32-bit channel for the graphics controller to directly access main memory.
The mainboard supports 4x/8x 1.5V AGP card. The motherboard provides one AGP slot and three 32-bit PCI bus slots.
AGP Slot
PCI Slots
PCI (Peripheral Component Interconnect) Slots
The PCI slots allow you to insert the expansion cards to meet your needs.  When
adding or removing expansion cards, make sure that you unplug the power supply
first. Meanwhile, read the documentation for the expansion card to make any neces-
sary hardware or software settings for the expansion card, such as jumpers,
switches or BIOS configuration.
PCI Interrupt Request Routing
The IRQ, acronym of interrupt request line and pronounced I-R-Q, are hardware lines
over which devices can send interrupt signals to the microprocessor.
The PCI IRQ pins are typically connected to the PCI bus INT A# ~ INT D# pins as
follows:
Order 1 Order 2 Order 3 Order 4
PCI Slot 1 INT A# INT B#INT C# INT D#
PCI Slot 2 INT B#INT C# INT D# INT A#
PCI Slot 3INT C# INT D# INT A# INT B#

Chapter 3. BIOS Setup
This chapter provides information on the BIOS Setup program and allows
you to configure  the system for optimum use.
You may need to run the Setup program when:
” An error message appears on the screen during the system booting
up, and requests you to run SETUP.
” You want to change the default settings for customized features.

1. The items under each BIOS category described in this chapter are
under continuous update for better system performance.
Therefore, the description may be slightly different from the latest
BIOS and should be held for reference only.
2. While booting up, the BIOS version is shown in the 1st line ap-
pearing after the memory counting. It is usually in the format:
example: W7005MS V2.0 091096
where:
1st digit refers to BIOS maker as A=AMI(R); W=AWARD(R)
2nd - 5th digit refers to the model number.
6th - 7th digit refers to the customer, MS=all standard customers.
V2.0 refers to the BIOS version.
091096 refers to the date this BIOS is released.
