Recommendations

This mainboard automatically determines the CPU clock frequency 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.

Overclocking components can adversely affect the reliability 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.

Components on this mainboard can be damaged by discharges of static
electricity. Handle the board carefully holding it by the edges. Don’t flex
or stress the circuit board. Keep the board in its static-proof packing until
you are ready to install it. Follow the static guidelines given at the
beginning of chapter 2.

Features

The key features of this mainboard are the advanced VIA VT82C694X/
VT82C596B chipset, and the FC-PGA processor support so that you can
install a wide range of Intel Celeron, Cyrix Joshua, or Intel Coppermine
processors. You can use this board to develop a low-cost value system,
with very comprehensive features.

Support PGA Intel Celeron/Cyrix Joshua and FC-PGA Intel
Coppermine Processor

This mainboard supports three kinds of processors: PGA Intel Celeron
and Cyrix PGA Joshua processors, and FC-PGA Intel Coppermine
processors.

The new generation PGA Celeron processors ship in the familiar square
plastic package, and they install in a Zero Insertion Force (ZIF) socket
called a Socket-370. The new Celeron processors are close to Pentium­II performance because they include a level-2 cache memory of 128K.
However, they operate over a 66 MHz system bus and they currently
ship at clock speeds of up to 533 MHz.

The new Cyrix PGA Joshua processors also fit into the Socket-370. The
Joshua will include a 256K on-chip L2 cache, which runs at full
processor speed. It is the first non-Intel chip to plug into the same socket
as a Celeron. The Cyrix Joshua runs over a 100 and 133 MHz system
bus.

The FC-PGA Coppermine processor operates over a 66, 100 or 133
MHz system bus. The FC-PGA Coppermine ships with clock speeds
running from 500 MHz through to 750 MHz.

Assemblers can choose the processor they need to meet performance or
price targets. You can configure the system for any of the supported
processor clock speeds using the BIOS setup utility. It is not necessary
to set switches or jumpers.

Three DIMM Memory Slots

The board has three DIMM slots for the installation of 168-pin, 3.3V
standard or registered SDRAM (Synchronous Dynamic Random Access
Memory) memory modules. The system supports memory that has built­in error correction (EC), error correction code (ECC), or has no error
correction.

4

The DIMM slots support PC-100 (100 MHz) and PC-133 (133 MHz)
memory modules. You can install one, two or three modules. Each
memory module can hold a maximum capacity of 512 MB of standard
SDRAM chips so max imum memory capacity is 1.5 GB.

The VIA chipset on this board supports an asynchronous memory bus
architecture, and provides option of 66/100, 100/66, 100/133 or 133/100
MHz CPU and memory bus combinations.

Optimized Chipset

This board uses the VIA VT82C694X/VT82C596B chipset. The
VT82C694X forms the north bridge and supports system buses of 66,
100 and 133 MHz. It is AGP Rev. 1 compliant and supports 3.3v AGP
devices operating over a 66/133 MHz bus. The memory bus supports the
fastest access (X-1-1-1) for both 66, 100 and 133 MHz operation. The
board is compliant with PCI Rev.2.1 operating at 33 MHz Four PCI Bus
masters are supported.

The south bridge is provided by the VT82C596B. This chip supports
ACPI (Advanced Configuration and Power Interface) Rev 1.0, onboard
PCI IDE channels, USB ports, and a System Management Bus for OS
control and configuration of devices.

This new VIA chipset is designed to lower cost of performance, by
offering a cheap solution to using the latest range of processors, while
offering a clear upgrade path to the future generation of 133 MHz
processor types. This chipset makes the evolutionary move from PC100
to PC133, increasing the speed of the system and memory buses from
100 MHz to 133 MHz. The 133 MHz memory interface also opens the
door to a wide range of PC133 memory devices now on the market.

This latest VIA chipset supports asynchronous memory bus architecture,
and provides the option of 66/100, 100/66, 100 /13 3 and 133/ 100 MHz
CPU and memory bus combinations. By supporting 66/100/133 CPU bus
and memory settings, this chipset is a highly scaleable choice for end
users building Celeron or Joshua level systems, and allows for a wide
range of cost-effective system design options.

Built-in PCI 3D Sound

The CMI 8738 is a single chip solution for PCI-bus 3D audio. The chip
provides Sound Blaster 16-bit-compatible audio, plus support for
Microsoft’s DirectSound 3D specification and Aureal A3D interface. The
sound ports include jacks for speak ers, mic rophone and st ereo in, and a

5

game/MIDI port. The audio system supports full duplex operation and
drivers are available for WIN 95/98/2000 and WIN NT 4.0. The audio
system can output sound to 4 loudspeakers and also supports SPDIF
24-bit digital sound input and output.

Optional Built-in Communications

The mainboard has an integrated fax/modem connector. As an option,
you can purchase a fax/modem extension bracket which connects the
line and telephone RJII sockets to the board. The fax/modem supports
the V.90 protocol that allows transmissions at up to 56Kbps and is fully
compatible with earlier transmission and error correction standards. It
supports automatic fall back and caller ID.

Expansion Options

Although this is an ATX board, it has a generous allocation of
expansions slots. One AGP slot is available for the installation of an
Accelerated Graphics Port graphics adapter. Four 32-bit PCI slots can
be used by PCI expansion cards. One legacy 8/16-bit ISA slot can be
used by ISA cards.

Integrated I/O

The board has a comprehensive set of integrated I/O ports. The I/O port
array features PS/2 keyboard and mouse ports, a parallel port, two USB
ports, two serial ports, a monitor port, a game/MIDI port, and three audio
jacks. Optionally, you can use the built-in mainboard header to add in an
infrared port. The mainboard has two PCI-IDE channels and a floppy
disk drive interface.

Hardware Monitoring

The mainboard is installed with an integrated hardware monitoring
system (GL520SM). Using this system and the monitoring software
supplied with the board, users and system administrators can monitor
critical parameters such as the CPU temperature, the fan speeds and so
on. Hardware monitoring helps maintain the system and reduce
maintenance costs and downtime.

Keyboard Power On Feature

Using the system BIOS setup program, you can configure the system to
turn on using a keyboard-typed password. A green keyboard is not
required.

6

Programmable Firmware

The mainboard includes Award BIOS that allows BIOS setting of CPU
parameters. The fully programmable firmware enhances the system
features and allows users to set power management, CPU and memory
timing, LAN and modem wake-up alarms, and so on. 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.

Before You Begin

Before you begin to install your MS7157C mainboard, take some
precautions to ensure that you avoid the possibility of damage to 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 discharge
through the integrated circuits and silicon chips on this product. These
circuits and chips are sensitive and can be permanently damaged by
static discharge.

♦

If possible wear a grounding wrist strap clipped to a safely
grounded device during the ins ta lla tio n.

♦

If you don’t have a wrist strap, discharge any static by touching
the metal case of a safely grounded device before 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.

Choosing a Case

This is a full-sized ATX mainboard that measures 304mm x 200mm
(11.9” x 7.8”). It has 6 expansion slots. The mainboard will fit most ATX
cases that are designed for full-sized ATX mainboards. With a full set of
expansion slots and support for 4 IDE devices, you might like to choose
a case that has a robust power supply unit that delivers at least 250
watts.

Some features on the mainboard are implemented by cabling connectors
on the board to indicators and switches on the system case. Ensure that
your case supports all the features required. The MS7157C mainboard
can support one or two floppy diskette drives and four enhanced IDE
drives. Ensure that your case has sufficient power and space for all the
drives that you intend to install.

13

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.

How to Set Jumpers

A jumper consists of two or more pins mounted on the mainboard. 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 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.

This illustration shows a 2-pin jumper. When the

OPEN

SHORT

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.

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 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.

JP1: Clear CMOS Memory Jumper

This jumper lets you erase the system setup settings that are stored in
CMOS memory. You might need to erase this data if incorrect settings
are preventing your system from operating. To clear the CMOS memory,
turn off the system, disconnect the power cable from the mainboard, and
short the appropriate pins for a few seconds.

JP9: Set System Bus Frequency to 100MHz

Use this 3-pin jumper to set the system bus frequency. In the normal
setting, the system automatically selects the correct frequency according
to the kind of processor installed. In the Force 100 MHz setting, the
system uses a 100 MHz system bus even if the processor is designed to
operate with a 66 MHz bus.

Use this 3-pin jumper to set the system bus frequency. In the normal
setting, the system automatically selects the correct frequency according
to the kind of processor installed. In the Force 133 MHz setting, the
system uses a 133 MHz system bus even if the processor is designed to
operate with a 100 MHz bus.

Note: When both JP9 and JP10 have the 2-3 pins shorted, the
board is set to force a 66 MHz FSB processor to run on a 133
MHz system bus.

JP11, JP12 and JP13: Select Celeron or Joshua Processor for
Socket-370

Use these 3-pin jumper sets to select the processor type you are using in
the PGA370 processor socket. If pins 1-2 are shorted, the Socket-370 is
set for use with the Intel Celeron processor. If pins 2-3 are shorted, the
Socket-370 is set for use with the Cyrix Joshua processor.
