INTRODUCTION
The Micro ATX IR2 mainboard is a high-performance personal computer
mainboard based on the AMD Athlon®processor. This mainboard provides
onboard Creative®ES1373 PCI technology in audio. The AMD Athlon®
processor is the newest microprocessor in the AMD K86TM family of
microprocessors.
The mainboard uses the highly integrated AMD®751 system controller and
AMD 756 peripheral controller. The AMD-751 system controller features:
the S2k system interface supports a 100Mhz clock and double-data rate
(DDR) transfers, the 33MHz 32-bit bus interface supports up to three
masters, the 66MHz AGP 1.0 compliant interface supports 2x data transfer
mode, and High Speed memory designed to support a 100MHz SDRAM
(PC-100-compatible-DIMM) with serial presence detect (PSD). The AMD-
756 peripheral bus controllers feature an integrated ISA bus controller, an
enhanced IDE controller with Ultra DMA-66 support, and a
keyboard/mouse controller.
THe MS-6191 ATX IR2 mainboard is one of our system board to implement the
AMD-750 chipset (AMD-751 and AMD-756), which supports a single Slot A
for AMD Athlon®processor.

HARDWARE INSTALLATION
2.1 Central Processing Unit: CPU
2.1-1 CPU Installation Procedures
Step 1: Install the Retention Mechanism.
Attach the Retention Mechanism to the Mainboard. Push the Plastic
lock to secure the Retention Mechanism into the mainboard.
Step 2: Install the Processor.
Insert the Processor like inserting a PCI or an ISA card.
Step 3: Lock the Processor.
Lock the processor by pulling up the Retention Mechanism
processor lock shown above.
Note: The Retention Mechanism processor lock can only lock S.E.C.C. 2
and S.E.P.P. processor.

2.1-2 CPU Core Speed Derivation Procedure
The Mainboard can auto-detect the processor speed. Just insert the AMD
Athlon processor into Slot A.
If CPU Clock = 100MHz
Core/Bus ratio = 5
then CPU core speed = Host Clock x Core/Bus ratio
= 100MHz x 5
= 500MHz

2.1-4 Fan Power Connectors: J9, J12, and J6
These connectors support system-cooling fan with +12V. It supports three pin
head connector. When connecting the wire to the connector, always take note
that the red wire is the positive and should be connected to the +12V, the black
wire is ground and should be connected to GND.

2.2 Clear CMOS Jumper: JBAT1
A battery must be used to retain the mainboard configuration in CMOS
RAM. Short 1-2 pins of JBAT1 to store the CMOS data.
Note: You can clear CMOS by shorting 2-3 pin, while the system is off.
Then, return to 1-2 pin position. Avoid clearing the CMOS while
the system is on, it will damage the mainboard. Always unplug
the power cord from the wall socket.
