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
Frequency Configuration
If you install a PU on this mainboard, you must set PU Frequency Ratio(JP4) and
JP2A/JP2B for External lock Frequency.
* CPU Speed = Frequency ratio x External clock (System) Frequency
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)

Front Panel Connector Set (CN1A 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/Green LED 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 or the Green
button is pressed again. The system resumes in different ways as defined by
"Power Management Setup" screen in BIOS.
D. System eset 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.

Clear CMOS Data (JP1
To clear the contents of the MOS, please follow the steps
below.
1. Disconnect the system power supply from the power source.
2. Set the jumper cap at location 2~3 for 5 seconds, then set it back
to the default position.
3. onnect the system's power and then start the system.
4. Enter BIOS's MOS Setup Utility and choose Load Setup
Defaults. Type Y and press enter.
5. Set the system configuration in the Standard MOS Setup
menu.
External Clock Frequency (JP2A/JP2B
This jumper allows the system bus frequency to be determined
either by PU or the user. If set both JP2A/JP2B pins to 1-2, the
PU determines the system bus frequency speed. Set both JP2A/
JP2B pins to 2-3 for 66MHz FSB, set only JP2B pins to 2-3 for
100MHz FSB and leave both JP2A/JP2B pins open for 133MHz
FSB.
Optional Frequency Ratio Setting (JP4
This feature allows you to set a PU at a higher frequency clock ratio than it's specifi-
cation allows. it may or may not run at that ratio, depending on the quality of your PU
and the extent to which the ratio has been overset.
Power On By Keyboard (JP5
This board is able to be turned on by the PS/2 keyboard (hot
key). To use this function, select a hot key of your choice at
the PS2KB Wakeup option under Wake Up Events in the BIOS's

menu (Figure 3-1), the screen below is displayed. his sample screen contains the
manufacturer's default values for the mainboard.
A. Anti-Virus Protection
Trend +DEF)M=OVirus
rend ChipAway Virus is a code incorporated in the mainboard's BIOS firmware.
During the boot-up sequence, BIOS loads before loading of the partition table
or boot sector. ChipAway Virus loads with BIOS and is able to detect boot-
up viruses before they have a chance to infect the hard drive. ChipAway Virus
employs rule-based logic that doesn't look for specific viruses but rather detects
patterns found in every virus, eliminating the need to perform periodical version
updates after new viruses have been found.

B. Cache Control
CPU Internal Cache/External Cache
Cache memory is much faster than conventional DRAM system memory. hese
fields allow you to enable or disable the CPUs Level 1 built-in cache and Level
2 external cache. Both settings are left enabled to significantly increase the
performance of your computer.
C. Processor Number Feature
If you have Pentium III processor installed on the mainboard. Enable this option
allows the serial code inside the Pentium III processor to be published on certain
application.
D. Boot Up Features
After turning on the system, BIOS will perform a series of device initialization
and diagnostic tests discussed below.
Quick Power On Self Test (POST)
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 boot
up 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 include 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
This function defines the keyboard's number pad as number keys or arrow keys.
E. Keyboard nterface
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.

Award BIOS Setup Program
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 ( sec)
he typematic delay sets how long after you press a key that a character begins
repeating.
F. 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.
G. 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.
H. Shadow Memory
Software such as system BIOS, video BIOS, SCSI BIOS, etc that resides in ROM
(Read Only Memory) chips is called firmware. Shadowing of firmware occurs
when BIOS is copied to RAM address C0000h through DFFFFh. Video BIOS
loads into the C0000-C7FFF memory area when video shadowing is enabled.
If an expansion peripheral in your system contains ROM-based firmware, you
need to know the address range the ROM occupies to shadow it into the correct
area of RAM.
Shadowing improves the firmware's performance because the firmware can be read
by the CPU through the 16- or 32-bit DRAM bus as opposed to the 8-bit X
bus. However, shadowing also results in reducing the amount of high memory
(640 KB to 1 MB) for loading device drivers. Shadowing is used mostly for
ROM chips on ISA cards and not for PCI cards. Shadowing and playing games
at the same time may result in system instability as some games access the RAM
memory area being shadowed.
