Introduction
Connecting devices to a CPU local bus can dramatically increase the speed
of I/O-bound peripherals with only a slight increase in cost over traditional
systems.
This price / Performance point has created a vast market potential for local
bus products.
The main barrier to this market has been the lack of an accepted standard
for local bus peripherals.
Many mainboard and chipset manufactures developed their own local bus
implementations, but they are incompatible with each other.
The VL (Video Electronics Standards Association) local bus and PCI
(Peripheral Component Interconnect) bus specification was created to end
this confusion.
The PCI - bus standard, under development since Jun. 1992, which is
designed to bring workstation-level performance to standard PC platform.
The PCI - bus removes many of the bottlenecks that have hampered PC for
several years.
On the PCI - bus, peripherals operate at the native speed of the computer
system, thus enabling data transfer between peripherals and the system at
maximum speed.
This performance is critical for bandwidth-constrained devices such as video,
multimedia, mass storage, and networking adapters.
PCI - bus standard provides end-users with a low-cost, extendible and
portable local bus design, which will allow system and peripherals from
different manufactures to work together.

1.7. What is AGP
The Accelerated Graphics Port (AGP) is a new port on the Host-To-PCI
bridge device that supports an AGP port. The main purpose of the AGP port
is to provide fast access to system memory.
The AGP port can be used either as fast PCI port (32-bits at 66MHz vs. 32bits at 33MHz) or as an AGP port which supports 2x data-rate, a read queue,
and side band addressing. When the 2x-data rate is used the port can
transmit data at 533Mb/sec (66.6*2*4). The read-queue can be used to
pipeline reads – removing the effects of the reads-latency. Side band
addressing can be used to transmit the data address on a separate line in
order to further speed the transaction.

3. HARDWARE INSTALLATION
3.1. UNPACKING
The mainboard package should contain the following:
• The 5SG100 mainboard.
• USER’ S MANUAL for mainboard.
• Cable set for IDE
¡B
Floppy & I/O Port .
• Diskette for Driver.
The mainboard contains sensitive electric components which can be easily
damaged by static electricity, so the mainboard should be left in its original
packing until it is installed.
Unpacking and installation should be done on a grounded anti-static mat.
The operator should be wearing an anti static wristband, grounded at the
same point as the anti-static mat.
Inspect the mainboard carton for obvious damage. Shipping and handling
may cause damage to your board. Be sure there are no shipping and
handling damage on the board before proceeding.
After opening the mainboard carton, extract the system board and place it
only on a grounded anti-static surface component side up. Again inspect the
board for damage.
Press down on all of the socket IC’ s to make sure that they are properly
seated. Do this only on with the board placed on a firm flat surface.
M
DO NOT APPLY POWER TO THE BOARD IF IT HAS BEEN DAMAGED.
It is assumed that the chassis is designed for a standard IBM XT/AT
mainboard mounting. Place the chassis on the anti-static mat and remove
the cover.
Take the plastic clips, Nylon stand-off and screws for mounting the system
board, and keep them separate.

3.4. DRAM INSTALLATION
The mainboard can be installed with 8/16 / 32 / 64 / 128 / 256 MB 168 pins
DIMM module DRAM, and the DRAM speed must be 67~100 MHz for
SDRAM. The DRAM memory system on mainboard consists of bank 1,2&
bank3.
Because the 168 pins DIMM module is 64 bits width, using 1 PCS which can
match a 64 bits system. The total memory size is 8 MB ~ 256 MB DRAM.
The DRAM installation position refer to Figure 3.1, and notice the Pin 1 of
DIMM module must match with the Pin 1 of DIMM socket. Insert the DRAM
DIMM module into the DIMM socket at Vertical angle. If there is a wrong
direction of Pin 1, the DRAM DIMM module couldn't be inserted into socket
completely.
3.5. SRAM INSTALLATION
Sync. SRAM (Pipeline Burst SRAM)
If Sync SRAM Chip is installed, it consists of Pipeline Burst 1 Pc 64 K x 64
512KByte.
There is no jumper for cache size setting.
3.6. CPU INSTALLATION AND JUMPERS SETUP
The system speed depends on the frequency of CLOCK GENERATOR. The
user can change SW2 selection to set up the system speed to 60 or 66 or 75
or 83 or 95 or 100 MHz for 3.3V/2.5V Pentium Processor (90-233 MHz) /
AMDK5(PR133/PR166)AMDK6(166/180/200(2.9V)/233(3.2V)/266/300(2.2V))
/AMD-K6-2 (250/266/300/333/350)(2.2V),Cyrix / IBM 6x86 (PR150+ /
PR166+/ PR200+), Cyrix / IBM 6x86L (PR150+/PR166+/PR200+ (2.8V)),
Cyrix / IBM 6x86MX (PR166 (60x2.5 2.9V) / PR200 (66x2.5 2.9V) (75x2
2.9V)/ PR233 (66x3 2.9V) (75x2.5 2.9V) / PR266 (66x3.5 2.9V) (75x3
2.9V) (83x2.5 2.9V)) IBM MX PR333 (100*2.5 2.9V).
The mainboard can use Pentium Processor, P54CT, MMX or P54CTB,
AMDK5, AMD-K6, AMD-K6-2, Cyrix / IBM 6x86, CPU, and the CPU speed
must match with the frequency of CLOCK GEN. It will cause system hanging
up if the CLOCK GEN.'S frequency is faster than CPU's.

M
The CPU is a sensitive electric component and it can be easily
damaged by static electricity, so users must keep it away from
metal surface when the CPU is installed onto mainboard.
M
When the user installs the CPU on socket, please notice that the
PIN 1 of CPU is in the same corner as the PIN 1 of socket!
M
Before the CPU is installed, the mainboard must be placed on a flat
plane in order to avoid being broken by the pressure of CPU
installation.
3.7. CMOS RTC & ISA CFG CMOS SRAM
Built-in Real Time Clock (RTC) With 256B CMOS SRAM in SiS5595.
3.8. SPEAKER CONNECTOR INSTALLATION
There is a speaker in AT system for sound purpose. The 4 - Pins connector
SPK is used to connect speaker.
The speaker can work well in both direction of connector when it is installed
to the connector SPK on mainboard.
3.9. ACPI LED & KEY LOCK CONNECTOR INSTALLATION
This mainboard uses the existing power LED as ACPI LED .The ACPI LED
will light on when system is power-on .The ACPI LED is off when the system
is power-off. The ACPI LED will blink when system is in Green mode.This
connector should be installed to ACPI LED jumper of the mainboard in
correct direction.
3.10. HARDWARE RESET SWITCH CONNECTOR INSTALLATION
The RESET switch on panel provides users with HARDWARE RESET
function which is almost the same as power-on/off. The system will do a cold
start after the RESET switch is pushed and released by user. The RESET
switch is a 2 PIN connector and should be installed to RST on mainboard.
3.11. GREEN FUNCTION INSTALLATION
There is one jumper for the purpose of power saving, GN , to indicate the
3-7
Page 19
Hardware Installation
power saving function . This mainboard uses the existing power LED as
ACPI LED . If the ACPI LED is blinking, the system is in green mode. The
GN switch will force the system into green mode .
3.12. PERIPHERAL DEVICE INSTALLATION
After installation of the device and setup of the jumpers, the mainboard can
be mounted into the case and fixed by screw. To complete the mainboard
installation, the peripheral devices could be installed now. The basic system
needs a display interface card and a storage device.
If a PCI - Bus device is to be installed in the system, any one of four PCI Bus slots can be used for Slave or Master PCI - Bus device.
After installing the peripheral device, the user should check everything again
and prepare to power-on the system.
