If your mainboard has already been installed in your computer you may still need
to refer to this chapter if you plan to upgrade your system's hardware.
2-1 Installing a CPU in a Socket 370
The Intel Socket 370, designed for the eleron/ oppermine processor, has been
incorporated as a standard mainboard specification To insert your PU into Socket
370 please do the following:
1. Locate a small dot marked on the top surface of the PU close to one if it's corners.
The same corner will also be cut off, leaving a noticeable notch in the PU's corner.
These markings indicate Pin 1 of the PU.
2. Pull up the lever of Socket 370 so that it is perpendicular with the surface of the
mainboard. Gently insert the PU with Pin 1 at the same corner of Socket 370
that contains the end of the lever. Allow the weight of the PU to push itself
into place. Do not apply extra pressure as doing so may result in damaging your
PU. Snap the lever back into place.
Installing a heat sink with cooling fan is necessary for proper heat dissipation
from your CPU. Failing to install these items may result in overheating and
possible burn-out of your CPU.
The use of a eatsink and Fan designed for the FC-PGA on a FC-PGA2 can cause
damage to the socket or motherboard and will void any warranty. The extra
thickness created by the I S will cause the eatsink and fan retention clip to
exert extra stress on the Socket, Processor or Motherboard.
2-2 Setting Your CPU's Parameter
This board support plug and play PU configuration, if you install a PU on this
mainboard, the board will automatically detect and set PU parameters. It is no longer
necessary to make many jumper settings as on conventional mainboards.
You can also manually configure your PU clock ratio according to your processor's
specifications by selecting a desire PU clock ratio at the SeePU Setup option in the
the CMOS Setup Utility (Section 3-8).
You do not need to make voltage settings because SeePU automatically sets
your CPU voltage.

2-3 Connector and Jumper Settings
onnectors are used to link the system board with other parts of the system, including
the power supply, the keyboard, and the various controllers on the front panel of
the system case.
The power supply connector is the last connection to be made while installing a
mainboard. Before connecting the power supply, please make sure it is not
connected to the power source.
ATX Power Supply Connector (PW1
The power cord leading from the system's power supply to the
external power source must be the very last part connected when
assembling a system.
The ATX power supply provides a single 20-pin connector
interface which incorporates standard +/-5V, +/-12V, optional 3.3V
and Soft-power signals. The Soft-power signal, a 5V trickle supply
is continuously supplied when A power is available. When the
system is in the Soft-Off mode, this trickle supply maintains the
system in it's minimum power state.
Software Power-Off Control
This mainboard can be powered down using theWindows 95 Software Power-Off
function. To power down your computer, click the START button on the Windows 95
task bar. Select "Shut Down The omputer" and the system turns off. The message "It
is now safe to turn off your computer" will not be shown when using this function.
Power-On By Modem
While in Soft-off state, if an external modem ring-up signal occurs, the system wakes up
and can be remotely accessed. You may enable this function in BIOS's Power
Management Setup menu. (See section 3-5)
Blinking LED in Suspend Mode
While in Suspend mode, the LED light on the front panel of your computer will flash.
Suspend mode is entered by pressing the Override Power Button, pushing the Green
button on your ATX case, or enabling the Power Management and Suspend Mode
options in BIOS's Power Management menu. (See section 3-5)
Poly-fuse Over Current Protection
The poly-fuse protects the system from dangerous voltages the system might be
exposed to via the keyboard or USB connectors. In case of such exposure, the poly-
fuse will immediately be disconnected from the circuit, just like a normal fuse. After
being disconnected for a certain period of time, the poly-fuse will return to its normal
state, after which the keyboard or USB can function properly again. Unlike
conventional fuses, the poly-fuse does not have to be replaced, relieving the user
wasted time and inconvenience.

Front Panel Connector Set (CN1 A through F
A. Over-ride Power Button Connector
The power button on the ATX chassis can be used as a
normal power switch as well as a device to activate
Advanced Power Management Suspend mode. This mode
is used for saving electricity when the computer is not in use
for long periods of time. The Soft-OFF by PWR-BTTN
function in BIOS's Power Management Setup menu must be
set to "Delay 4 Sec." to activate this function.
When the Soft-OFF by PWR-BTTN function is enabled,
pushing the power button rapidly will switch the system to
Suspend mode. Any occurence of external activities such
as pressing a key on the keyboard or moving the mouse will
bring the system back to Full-On. Pushing the button while
in Full-On mode for more than 4 seconds will switch the
system completely off. See Over-ride Power Button
Operation diagram.
B. Power Indicator LED Connector
The power indicator LED shows the system's power status. It is important to
pay attention to the correct cables and pin orientation (i.e., not to reverse the order
of these two connectors.)
C. Green Switch Connector
Some ATX cases provide a Green switch which is used to put the system in
Suspend mode. In Suspend mode, the power supply to the system is reduced
to a trickle, the PU clock is stopped, and the PU core is in it's minimum power
state. The system is woken up whenever the keyboard or mouse is touched. The
system resumes in different ways as defined by Power Management Setup screen
in BIOS.
D. Syste Reset Switch Connector
This connector should be connected to the reset switch on the front panel of
the system case. The reset switch allows you to restart the system without turning
the power off.
E. Speaker Connector
This 4-pin connector connects to the case-mounted speaker
F. IDE Activity LED Connector
The IDE activity LED lights up whenever the system reads/writes to the IDE
devices.

Enable this function to reduce the amount of time required to run the POS (Power
On Self est). BIOS saves time by skipping some items during POS . It is
recommended that you disable this setting. Discovering a problem during bootup
is better than loosing data during your work.
First/Second/Third/Boot Other Device
his option sets the sequence of drives BIOS attempts to boot from after POS
completes. BIOS will search these drives for an operating system.
Swap Floppy Drive
Enabling this function will swap the floppy drive assignment so that drive A will
function as drive B, and drive B will function as drive A. Note that the boot
sequence assignment mentioned directly above does not inlcude booting from
floppy drive B. his function is useful if floppy drives B and A are of a different
format and you want to boot from floppy drive B.
Boot up Floppy Seek
During POS , BIOS will determine if the installed floppy disk drive has 40 or 80
tracks. A 360K drive has 40 tracks and 720K, 1.2M and 1.44M drives have 80 tracks.
All modern floppy disk drives have 80 tracks.
Boot Up NumLock Status
his function defines the keyboard's numberpad as number keys or arrow keys.
E. ate A 20 Option
Gate A20 refers to the way the system addresses memory above 1 MB (extended
memory). When set to Fast, the system chipset controls Gate A20. When set to
Normal, a pin in the keyboard controller controls Gate A20. Setting Gate A20 to
Fast improves system speed, particularly with OS/2 and Windows.

F. Keyboard Interface
Typematic Rate Setting
When enabled, you can set the following two typematic control items. When
disabled, keystrokes are determined arbitrarily by the keyboard controller in your
system.
Typematic Rate (Chars/Sec)
he typematic rate sets the rate at which characters on the screen repeat when
a key is pressed and held down.
Typematic Delay (Msec)
he typematic delay sets how long after you press a key that a character begins
repeating.
. Security Option
he Supervisor and/or User Password functions shown in Figure 3-1 must be set
to take advantage of this function. See Section 3-11 for password setting
information. When the Security Option is set to System, a password must be
entered to boot the system or enter the BIOS setup program. When the Security
Option is set to Setup, a password is required to enter the BIOS setup program.
H. OS Select (For DRAM > 64MB)
If your system's DRAM is larger than 64MB and you are running OS/2, select
OS/2 as the item value. Otherwise, set the item value to Non-OS/2 for all other
operating systems.
