1.5. INTRODUCE THE PCI - BUS
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.
1.6. FEATURES
q32 bits bus transfer mode.
qBus Master or Slave access.
qMemory burst transfer to 132 MB/sec.
q33 MHz operation speed.
q10 device loading ability.
qCPU independent.

3. HARDWARE INSTALLATION
3.1. UNPACKING
The mainboard package should contain the following:
•The 5SMM mainboard.
•USER’S MANUAL for mainboard.
•Cable set for IDE ¡B Floppy.
•CD for Mainboard Utility.
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 ATX2.0 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. 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.
3.5. DRAM INSTALLATION
The mainboard can be installed with 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 0 & bank1¡Bbank2 .
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 16 MB ~ 768 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.

3.6. CPU INSTALLATION AND JUMPERS SETUP
The system speed depends on the frequency of CLOCK GENERATOR. The user can
change SW selection to set up the system speed to 66 / 75 / 83 / 90 / 95 / 100MHz
for 3.3V/2.5V PentiumProcessor (133 / 166 / 200 MHz) ;MMX(166 / 200 / 233
MHZ) , AMD K6-(166 / 200 / 233 / 266 / 300 ; K6-2(266 / 300 / 333 / 350 / 366 / 380
/ 400 / 450 / 475 / 500 / 550) ; K6-III(400 / 450 / 475 / 500 / 550) , Cyrix / IBM
6x86MX (PR166 / PR200 / PR233 / PR266 ) ; M¢º- PR300 / PR333 / PR350 /
PR366 / PR400) ; IDT Winchip 2-(200 / 225 / 233 / 266 / 300) ; IDT Winchip 3-(266) ;
RISE MP6-(266).
The mainboard can use PentiumProcessor, MMX , AMD-K6, AMD-K6-2, AMD-K6-
III Cyrix / IBM 6x86MX, Cyrix M¢º, IDT Winchip 2 , IDT Winchip 3 , RISE MP6 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.

3.8. 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. 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 RE on mainboard.
3.10. GREEN FUNCTION INSTALLATION
There is one jumper for the purpose of power saving, GN, to indicate the power
saving function . If the GD is lighted on, the system is in green mode. The GN switch
will force the system into green mode .
3.11. 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 three 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.
