This mainboard is built with CPU
Socket 478B ( 478-pin) supporting
the Intel Pentium 4 CPU:
• Follow the steps described in this
section to install the 478-pin Pentium 4 CPU into the on board
Socket 478.
• After installation of Pentium 4 CPU,
you must also install the specific
Pentium 4 CPU fan designed in
tandem with this CPU. This CPU
Fan installation is described in next
section.
• This mainboard supports Hyperthreading dual-in-one CPU, the
function of which can be enabled
by Windows XP. (See illustration
on the right.)
1. First pull sideways the lever of
Socket 478, and then turn it up
0
so as to raise the upper layer
90
of the socket from the lower
platform.
( If Hyper-threading CPU is
installed successfully with O/S
Win XP, the O/S will enable the
dual-in-one CPU function.)

Pin 1
2. Configure Pin 1 of CPU to Pin 1
of the Socket, just as the way
shown in the diagram on the
right. Adjust the position of CPU
until you can feel all CPU pins
get into the socket with ease.
3. Make sure that all CPU pins have
completely entered the socket
and then lower down the lever
to lock up CPU to socket.

2-5. To Install LAN Drivers (for 85MIV4-L only)
2-5.1 VIA6103 LAN Driver on Windows 9X
The LAN driver contained in the Support CD is not included in the
Autorun Menu. To install VIA6103 LAN driver on Windows 9X, please
follow the steps shown below:
1. On the “Start” screen of your system, click to the following path:
\My Computer\properties\Device manager
2. In the “Device manager” screen, you can see the item “ PCI Ethernet
Controller” with a yellow question mark on its left side, which indicates
that the LAN controller is already detected by system but the driver
for this on-board Ethernet Controller is not installed yet. Please point
to this item with your mouse and double click on it (or click the
“Properties” button).
3. Instantly, the “PCI Ethernet Controller
Properties“ screen shows up. Please
click the “General” bar to continue.

Chapter 3 BIOS Setup
Chapter 3 AMI BIOS Setup
3-1 To Update BIOS
• “AMIFLASH.EXE” is a Flash EPROM Programming utility that up-
dates the BIOS by uploading a new BIOS file to the programmable
flash ROM on the mainboard. This program only works in DOS
environment, the utility can not be executed in Windows 95/98,
ME, NT, 2000 or Windows XP environment.
• Please follow the steps below for updating the sys tem BIOS:
Step 1. Please visit the board maker’s website, download latest BIOS
file and AMI update utility. The file name of AMI update utility will be
“AMIXXX.EXE” of which “ XXX ” stands for the version number of the
file. The BIOS file format will be *.ROM, of which “ * ” stands for the
specific BIOS file name.
Step 2. Create a bootable diskette. Then copy the BIOS file and AMI
flash utility “AMIXXX.EXE” into the diskette.
Step 3. Insert the diskette into drive A, boot your system from the
diskette.
Step 4. Under “ A “ prompt, type “ AMIXXX.EXE *.ROM “ and then
press <Enter> to run BIOS update program. Please note that there
should be a space between AMIXXX.EXE and *.ROM. (*.ROM depends
on your mainboard model and version code. Instead of typing “*”, you
should type the specific file name for your specific mainboard).
Step 5. When the message “Flash ROM Update Completed - Pass.”
appears, please restart your system.
Step 6. You will see a message “CMOS Memory Size Wrong” during
booting the system. Press <Del> or <F1> to run CMOS setup utility,
then reload “LOAD SETUP DEFAULTS” or “Load Optimal Defaults”
and save this change.
