2.4 Function & Installation Instructions
2.4.1 AT Power Supply Connector (12-Pin)
This connector connects to a standard AT power supply. To connect the
leads from the power supply, ensure first that the power supply is not power
on.Most powersuppliesprovide twoplugs, andeachplug containssixwires.
Two of six wires are black and please orient the plugs to the connector so
that 4 black wires are together.
AT Power Connector
At a slight angle, align the plastic guide pins on the lead to their recep-
tacles on the connector. Once aligned, press the lead onto the connector
until the lead locks into place.
2.4.2 ATX Power Supply Connector (20-Pin)
Thisconnectorconnects to an ATX power supply.Theplug from ATXpower
supply will only insert in one orientation because of the different hole sizes.
Find the proper orientation and push down firmly making sure that the pins
are aligned. The system power can be turned off through software control,
like the shut down in Windows 2000 / ME / 98 / 95 start menu. Power man-
agement must be enabled in the system BIOS in order to activate this soft-
off feature. Once the system BIOS receives the power management com-
mand from the OS, it will switch the system power off.

EXPANSIONCARDS INSTALLATION
Beforeaddingor removing any expansion cards or systemcomponents,
confirmthat you alreadyunpluggedyour power supply.Otherwise,it may
severely damage to your motherboard and expansion cards. Please fol-
lowtheinstallation procedures as below:
1. Checkcarefully if those hardware orsoftwaresettings for your expansion
cards are in the proper position as shown in their User’s Manual.
2. Removeyour computer case’scoverand unscrew the bracketplatefor
those slots needed to insert.
3. Those expansion cards must be aligned on the slots firmly with good
connection.
4. Put on the computer case cover.
5. Ifneeded, setupthe BIOSconfiguration and installthe requireddriversfor
yourexpansion cards.
2.4.13 SDRAM Sockets
There are two SDRAM sockets on-board to provide more flexibility for your
systemmemory upgrade. Becausethe number ofpinsare different oneither

2.4.17 IDE Connectors (40-Pin)
The IDE connectors support the provided IDE HDD ribbon cable. After
connecting the single end to the board, connect the two plugs at the other
endto yourHDDs.If youinstall twoIDEdevices onthe samecable,you must
configurethe second device toslavemode by settingitsjumper accordingly.
(Refer to your IDE device document for the jumper settings. Pin 20 is re-

2.4.19 PGA ZIP CPU Socket
The motherboard provides a ZIF Socket 7. The CPU that attatch with the
motherboard should have a fan on it to prevent overheating. If it is not so,
purchase a fan before you turn on your system.
Notice !!!
Be sure that there is a sufficient air circulation across the processor’s
heatsink by regularly checking that your CPU fan is working. Without
sufficient circulation, the processor could be overheated and it may dam-
ageboththeprocessor and themotherboard.Youmay install an auxiliary
fan,ifnecessary.
Installation step:
1.Turnoff the powerof your system andremoveits cover;
2.Locate the ZIF socket and open it by first pulling the lever sideways away
fromthesocket then upwards to a90-degreeangle;
3.Insertthe CPU with correctorientation
(TheCPU has a cornerpinfor two ofthefour corners, that theCPU only fit
inthe orientation.)
4.Once completely inserted, pull down the socket’s lever to horizontal and
make sure the CPU is firmly locked in the socket.

2. Insert this CD disk into your CDROM drive.
3. The Explorer screen will then appear, that gives you instructions
forinstallation.
4. There may require restarts of Windows during some software

Type How to Configure
SCSI Select Type. Select Not Installed the drive parameter screen.
The SCSI drivers provided by the SCSI manufacturer should
allow you to configure the SCSI drive.
IDE Select Type. Select Auto to let AMIBIOS determine the param-
eters. Click on OK when AMIBIOS displays the drive param-
eters. Select LBA/Large Mode. Select On if the drive has a ca-
pacity greater than 540 MB. Select Block Mode. Select On to
allow block mode data transfers. Select 32-Bit Transfer. Select
On to allow 32-bit data transfers. Select the PIO Mode. It is best
to select Auto to allow AMIBIOS to determine the PIO mode. If
you select a PIO mode that is not supported by the IDE drive, the
drive will not work properly. If you are absolutely certain that you
know the drive’s PIO mode, select PIO mode 0-5, as appropriate.
CD-ROM Select Type. Select CDROM. Click on OK when AMIBIOS dis-
plays the drive parameters.
StandardMFM Select Type. You must know the drive parameters. Select the
drive type that exactly matches your drive’s parameters.
Non-Standard Select Type. If the drive parameters do not match the drive
MFM parameters listed for drive types 1-46, select User and enter the
correct hard disk drive parameters.
Entering Drive Parameters

Parameter Description
Type The number for a drive with certain identification parameters.
Cylinders The number of cylinders in the disk drive.
Heads The number of heads.
Write The actual physical size of a sector gets progressively smaller as
Precomp- the track diameter diminishes. Yet each sector must still hold
ensation 512 bytes. Write precompensation circuitry on the hard disk
compensates for the physical difference in sector size by boost-
ing the write current for sectors on inner tracks. This parameter
is the track number on the disk surface where write
precompensation begins.
Landing Zone This number is the cylinder location where the heads normally
park when the system is shut down.
Sectors Thenumber ofsectors pertrack. MFMdrives have17sectorspertrack.
RLL drives have 26 sectors per track. ESDI drives have 34 sectors
per track. SCSI and IDE drives have even more sectors per track.
Capacity The formatted capacity of the drive is the number of heads times
the number of cylinders times the number of sectors per track
times 512 (bytes per sector).
