System Installation Setup
Before using your computer, you must finish the following steps:
1. Set jumpers on mainboard
2. Install SDRAM module.
3. Install the Processor.
4. Connect Ribbon Cables, Cabinet Wires, and Power supply.
5. Install Add on Cards.
6. Setup the BIOS software.
Static Electricity Precaution
Keep the mainboard and other system components in their anti-
static packaging until you are ready to install them.
Do all preparative work on a static-free surface with the main
board components facing up.
Unplug your computer when working on the inside.
Wear an Anti-static wrist strap.
Hold the system components, boards or cards by its edges only.
Be careful not to touch any of IC chips, circuitry, contacts or
connections, especially gold contacts on the mainboard.

Jumper Settings
Jumpers
Several hardware setting are made through the use of jumper caps to
connect jumper pins (Jxx) on the mainboard. See " Map of the
mainboard" for the locationed the jumpers.
The jumper settings will be described numerically such as [----], [1-
2], [2-3] for no connection, connect pins 1 & 2, and connect pins 2 &
3 respectively. Pin 1 for our mainboard is always on top one or on
the left when holding the mainboard with the keyboard away from
yourself. "P1" is written besides pin 1 on jumper with three pins. The
jumpers will also be shown graphically such as to connect pin
1&2 and to connect 2&3. Jumpers with two pins will be shown
as for Short (on )and for Open (off).For manufacturing
simplicity it may be sharing pins from other groups. Use the diagrams
in this manual instead of following the pin layout on the board. Set-
tings with two jumper numbers require that both jumpers be moved
together. To connect the pin, simply place a plastic jumper cap over
the two pins as diagrammed.

Real Time Clock (RTC) RAM - JP15 :
The CMOS RAM is powered by the onboard button cell battery. To
clear the RTC data:
(1)Turn off your computer, (2) Move this jumper to "2-3Pin Clear
Data", (3) Move the jumper back to "Default", (4) Turn on your
computer, (5) Hold down <Delete > during bootup and enter BIOS
setup to re-enter user Preferences.

System Memory ( DIMM Module)
This 6M810C main board supports two 168 pins DIMM of 16 MB, 32
MB, 64 MB, 128 MB ,256MB to form a memory size between 16MB to
256MB.
The DRAM can be either Intel PC100-compaliant SDRAMs.
Install memory in any or all Banks in Combination:
Bank Memory module
DIMM 1 16MB,32MB,64MB,128MB,256MB
( Bank 0-1 ) 168 pin,3.3v SDRAM / EDO RAM
DIMM 2 16MB,32MB,64MB,128MB,256MB
( Bank 2-3 ) 168 pin 3.3v,SDRAM / EDO RAM
Total System Memory(Max 512MB)
Note :


At the time this user's manual was written, 256MB
DIMM's are only available as double-sided registered
memory (128Mbit cells). Using 2x2x2x SDRAM can
greatly improve the onboard graphics' performance.


The motherboard operates at 100MHz, therefore PC100-
compliant modules must be used because of the strict tim-
ing issues involved under this speed.

DIMM Memory Installation
Insert the module (s) as shown. Because the number pins are differ-
ent on either side of the breaks,the module will only fit in the orienta-
tion as shown. SDRAM DIMM modules have different pin contacts
on each side and therefore have a higher pin density.

14 / Chapter 3 Installation
The Dual Inline Memory Module (DIMM) memory module must be 3.
3v Extended Data Output (EDO) DRAM or SDRAM. You can identify
the type of DIMM module by the illustration below:
168 Pin DRAM DIMM Notch Key Definitions
The notch on the DIMM module will shift between left, center, or
right to identify the type and also to prevent the wrong type to be
inserted into the DIMM slot on the Mainboard. You must ask your
retailer for Specifications before purchasing.

CPU Installation
The motherboard provides a ZIF socket 370. The CPU that came
with the motherboard should have a fan attached to it to prevent
overheating . If this is not the case then purchase a fan before you
turn on your system.
To install a CPU , first turn off your system and remove its cover.
Locate the ZIF socket and open it by first pulling the lever sideways
away from the socket then upwards to a 90-degree right angle. Insert
the CPU with the correct orientation shown . The notched corner
should point towards the end of the lever. Because the CPU has a
corner pin for two of the four corners, the CPU will only fit in the
orientation as shown.

Wake On Keyboard -JP1
This allows you to disable or enable the keyboard power up
function.Set to enable if you want to use your keyboard (by
press <Spacebar> to power up your computer. This feature re-
quires an ATX power supply that can supply at least 300mA on
the +5VSB lead and the new ACPI BIOS support. The default is
set to Disable because not all computers have the appropriate
ATX power supply. Your computer will not function if you set
this to Enable and if you do not have the right ATX Power supply.

Safe Mode (SAFE_MD) -JP17
Usually socket 370 processors have locked frequency multiples.
In this case, there is no way to exceed the specified multiple
whether through motherboard setting or BIOS setup. With un-
locked socket 370 processors, exceeding the specified multiple is
possible through BIOS setup. Exceeding the specified multiple may
result in hanging during bootup. If this occurs, enable Safe Mode
to force a multiple of 2 in order to enter BIOS setup to correct the
problem.
Automatic Timeout Reboot Setting (NO_REBOOT) -JP16
The motherboard is set that when the BIOS detects a hang(timeout)
during bootup, the motherboard will automatically reboot in order
to try rebooting again. If rebooting is repeating ineffectively, set
this jumper to "No Reboot" so that auto reboot will be disabled.
