1.6 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. 32-
bits 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 speed up the transaction.

3. HARDWARE INSTALLATION
3.1. UNPACKING
The mainboard package should contain the following:
•The 6LMM7 mainboard.
•The Retention Mechanism & Attach Mount
•USER'S MANUAL for mainboard.
•Cable set for IDE, Floppy devices. (Cable for COMB is optional)
•CDs or diskettes for Mainboard ¡B(Sound and VGA 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 damages 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.

3.4. 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 50 or 60 ns for EDO &
66~100 MHz for SDRAM. The DRAM memory system on mainboard
consists of bank 0, 1 & bank 2.
Since 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 ~ 384MB SDRAM, EDO
DRAM size is 16MB ~ 768MB. 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. CPU SPEED SETUP
The default system bus speed is 66.6MHz. The user can change the DIP
SWITCH (SW) selection to set up the CPU speed for 366 - 566MHz
processor. The CPU speed must match with the frequency RATIO. It will
cause system hanging up if the frequency RATIO is higher 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 We don’t recommend you to setup your system speed to 75 or 83
MHz because these frequencies are not the standard specifications
for CPU, Chipset and most of the peripherals. Whether your system
can run under 75 or 83MHz properly will depend on your hardware
configurations: CPU, SDRAM, Cards, etc.
3.6. CMOS RTC & ISA CFG CMOS SRAM
The mainboard contains RTC & CMOS SRAM on board. They have a power
supply from external battery to keep the DATA inviolate & effective. The RTC
is a REAL-TIME CLOCK device, which provides the DATE & TIME to
system. The CMOS SRAM is used for keeping the information of system
configuration, so the system can automatically boot OS every time. Since
the lifetime of internal battery is 5 years, the user can change a new Battery
to replace old one when it has consumed.
3.7. SPEAKER CONNECTOR INSTALLATION
There is a speaker in AT system for sound purpose. The 4 -Pins connector
SPKR is used to connect speaker.
3.8. HARDWARE RESET SWITCH CONNECTOR INSTALLATION
The RESET switch on panel provides users with HARDWARE RESET
function. The system will do a cold start after the RESET switch is press and
released by user. The RESET switch is a 2 PINS connector and should be
installed to RES on mainboard.
3.9. POWER LED CONNECTOR INSTALLATION
System has power LED lamp on the panel of case. The power LED will light
on off or flash to indicate which step on the system. The connector should be

6LMM7
3-8
connected to LED of mainboard in correct direction.
3.10. IDE & ATAPI DEVICE INSTALLATION
There are two-Enhanced PCI IDE ports (IDE1, IDE2) on board, which
following ATAPI standard SPEC. Any one IDE port can connected to two
ATAPI devices (IDE Hard Disk, CD-ROM & Tape Driver), so total four ATAPI
devices can exist in a system. The HD is the active LED port for ATAPI
devices.
3.11. PERIPHERAL DEVICE INSTALLATION
After the I/O device installation and jumpers setup, the mainboard can be
mounted into the case and fixed by screw. To complete the mainboard
installation, the peripheral device could be installed now. The basic system
needs a display interface card. If the PCI - Bus device is to be installed in the
system, any one of three PCI - Bus slots can be used.
3.12.PS/2 KEYBOARD & MOUSE INSTALLATION
The main board supports PS/2 Mouse. The BIOS will auto detect whether the
PS/2 Mouse is installed or not & assign IRQ12 for PS/2 Mouse port if it is
installed. After installing the peripheral device, the user should check
everything again, and prepare to power-on the system.
