Caution! When installing a CPU heatsink and
cooling fan make sure that you DO
NOT scratch the motherboard or any of
the surface-mount resistors with the clip
of the cooling fan. If the clip of the
cooling fan scrapes across the main-
board, you may cause serious damage
to both the mainboard and the proces-
sor.
On most mainboards, there are small
surface-mount resistors near the proces-
sor socket, which may be damaged if
the cooling fan is carelessly installed.
Avoid using cooling fans with sharp
edges on the fan casing and the clips.
Also, install the cooling fan in a well-lit
work area so that you can clearly see
the mainboard and processor socket.

Recommendations
This mainboard automatically determines the CPU clock fre-
quency and system bus frequency for the kind of processor that
you install. You may be able to change these automatic settings
by making changes to jumpers on the mainboard, or changing
the settings in the system Setup Utility. We strongly recommend
that you do not overclock the mainboard to run processors or
other components faster than their rated speed.
Warning: Overclocking components can adversely affect the reliabil-
ity of the system and introduce errors into your system. Overclocking
can permanently damage the mainboard by generating excess heat
in components that are run beyond the rated limits.

modules can be SDRAM or VCM memory chips.
AGP Graphics Adapter Slot
The MS7127C includes a 2xAGP slot that provides twice the
bandwidth of the original AGP specification. AGP technology
provides a direct connection between the graphics sub-system
and the processor so that the graphics do not have to compete
for processor time with other devices on the PCI bus.
The AGP design allows the graphics controller to use part of the
main memory when it needs it, for example, in handling the very
large texture maps required by virtual reality and 3D video
games and applications.
AC 97 Audio Codec
The AC 97 Audio codec is compliant with the AC 97 2.1 specifi-
cation, and supports 18-bit ADC (Analog Digital Converter) and

MIDI/game port, two USB ports with an onboard header provid-
ing two extra USB ports, and audio jacks for microphone, line-in
and line-out. The board includes two PCI IDE channels and a
floppy disk drive interface.

6
Keyboard Power on Feature
Using the system BIOS setup program, you can configure the
system to turn on by pressing any key. A green keyboard is not
required.
Programmable Firmware
The mainboard includes Award BIOS that allows BIOS setting of
CPU parameters. This fully programmable firmware enhances
the system features and allows users to set such items as power
management, CPU and memory timing, and modem wake-up
alarms. The firmware can also be used to set parameters for
different processor clock speeds so that you don’t need to
change mainboard jumpers and switches.
This concludes Chapter 1. The next chapter will cover installing
and building a working system.

Before You Begin
Before you begin to install your mainboard, take care not to
damage the product from static electricity. Ensure too that you
are installing the mainboard into a suitable case.
Static Electricity
In adverse conditions, static electricity can accumulate and dis-
charge through the integrated circuits and silicon chips on this
product. These circuits and chips are sensitive and can be per-
manently damaged by static discharge.
•If possible, wear a grounding wrist strap clipped to a
safely grounded device during the installation.
•If you don’t have a wrist strap, discharge any static by
touching the metal case of a safely grounded device be-
fore beginning the installation.
•Leave all components inside their static-proof bags until
they are required for the installation procedure.
•Handle all circuit boards and electronic components
carefully. Hold boards by the edges only. Do not flex or
stress circuit boards.

9
Choosing a Case
The mainboard complies with the specifications for the Micro
ATX system case. Some features on the mainboard are imple-
mented by cabling connectors on the mainboard to indicators
and switches on the system case. Ensure that your case sup-
ports all the features required. The mainboard can support one
or two floppy diskette drives and four enhanced IDE drives. En-
sure that your case has sufficient power and space for all the
drives that you intend to install.
The mainboard has a set of I/O ports on the rear edge. Ensure
that your case has an I/O template that supports the I/O ports
and expansion slots.

Check the Jumper Settings
Check the mainboard jumpers to ensure that the board is con-
figured correctly.
How to Set Jumpers
A jumper consists of two or more pins mounted on the main-
board. Some jumpers might be arranged in a series with each
pair of pins numbered differently. Jumpers are used to change
the electronic circuits on the mainboard. When a jumper cap (or
shunt) is placed on two jumper pins, the pins are SHORT. If the
jumper cap is removed (or placed on just a single pin), the pins
are OPEN.
Short Open
This illustration shows a 2-pin jumper.
When the jumper cap is placed on
both pins, the jumper is SHORT. If
you remove the jumper cap, or place
the jumper cap on just one pin, the
jumper is OPEN.
This illustration shows a 3-pin jumper.
The jumper cap is placed on pins 2
and 3, so this jumper setting is
SHORT PINS 2-3.
This illustration shows the same 3-pin
jumper. The jumper cap is placed on
pins 1 and 2, so this jumper setting is
SHORT PINS 1-2.
In this manual, all the jumper illustrations clearly show the pin
numbers. When you are setting the jumpers, make sure that the
jumper caps are placed on the correct pins to select the function
or feature that you want to enable or disable.
