1.6 INTRODUCE AMR
The Audio Modem Riser (AMR) is a new port that supports both audio and
modem. The main purpose of the AMR port is to provide lower cost and
higher levels of integration at all levels of the PC platform.
The backbone of the AMR interface is on AC’97 compliant AC-Link with
support for codes. Motherboard support for an AMR interface are not only
capable of achieving the lowest possible cost for basic PC audio and
modem, but have also introduced increased motherboard flexibility enabling
robust, cost effective scalability.
The AMR is done through software and controlled by the motherboard’s I/O
Controller Hub (ICH). There are two types of AMR, one defined as primary
and another defined as secondary. If the motherboard with onboard sound
YAMAHA 744, the AMR must be used primary.

3. HARDWARE INSTALLATION
3.1. UNPACKING
The main board package should contain the following:
•The 6WMM7 / 6WMM7-1 main board.
•USER'S MANUAL for main board.
•Cable set for IDE, Floppy devices, [COMB Port Cable (Optional)].
•CD for main board Utility. [IUCD (Bus Master + Sound Driver + LDCM +
Utility), INTEL 82810 Driver.]
The main board contains sensitive electric components, which can be easily
damaged by static electricity, so the main board 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 main board 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 main board 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 main board can be installed with 16 / 32 / 64 / 128 / 256 MB 168 pins
DIMM module DRAM, and the DRAM speed must 100 MHz for SDRAM
when system bus speed is set to 66MHz or 100MHz, the DRAM memory
system on main board consists of bank 0 and bank 1.
Since 168 pins DIMM module is 64 bits width, therefore 1 piece of DIMM
module may match a 64 bits system. The total memory size is 16 MB ~
512MB SDRAM . 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 DIMM module into the DIMM socket at Vertical angle. If there is a
wrong direction of Pin 1, the SDRAM DIMM module could not be inserted
into socket completely.
3.5. CPU SPEED SETUP
The system bus frequency can be switched between 66MHz and 100MHz by
adjusting JP1. The CPU Frequency is control by BIOS.

JP1: Set System Bus Speed
MJP1 (Select the system speed between 66MHz / 100MHz and Auto)
1-2 Close Set system speed to Auto
− auto detect
system speed.
2-3 Close Set system speed to 66 MHz
− system always
run at 66MHz FSB (Front Side Bus).
1-2-3 Open Set system speed to 100 MHz
− system always
run at 100MHz FSB (Front Side Bus).
« Note: Please set the CPU host frequency in accordance with your
processor’s specifications. We don’t recommend you to set the
system bus frequency over the CPU’s specification because these
specific bus frequencies are not the standard specifications for
CPU, chipset and most of the peripherals. Whether your system
can
run under these specific bus frequencies properly will depend on
your hardware configurations, including CPU, Chipsets, SDRAM,
Cards….etc.
3.6. CMOS RTC & ISA CFG CMOS RAM
There're RTC & CMOS RAM 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 RAM 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 after it cannot work.
MDanger of explosion if battery is incorrectly replaced.
MReplace only with the same or equivalent type recommended by the
manufacturer.
MDispose of used batteries according to the manufacturer’s instructions.
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 pushed
and released by user. The RESET switch is a 2 PIN connector and should be
installed to RST on main board.
3.9. POWER LED CONNECTOR INSTALLATION
System has power LED lamp on the panel of chassis. The power LED will
light on off or flash to indicate which step on the system. The connector
should be connected to P+P-P- of main board in a correct direction.
3.10. IDE & ATAPI DEVICE INSTALLATION
There are two-Enhanced PCI IDE ports (IDE1, IDE2) on board, which
following ATAPI standard SPEC. Each IDE port can connected to two ATAPI
devices (IDE Hard Disk, CD-ROM or 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 main board can be
mounted into the chassis and fixed by screw. To complete the main board
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. KEYBOARD & PS/2 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 ready power-on the system.
