Congratulations on your new purchase of SOYO P4X400 Series

motherboard for the Intel platform!

This new motherboard offers support for ultra fast DDR400 memory.

However, since DDR400 is not a JEDEC (The Joint Electron Device

Engineering Council) approved memory specification, some users might

experience DDR400 incompatibilities as a result of discrepancy in memory

manufacturing.

In an effort to provide our customers the highest product quality and

performance, SOYO has tested a number of memory modules to ensure

compatibility. Please visit our web site at

http://www.soyousa.com/products/proddesc.php?id=159

on Recommended Memory.

In some cases BIOS upgrade might be required to take advantage of this

new feature. Please refer to our Support section on the web site for more

information.

Warning: Follow these precautions to preserve your Motherboard

from any remnant currents when connecting to ATX power supply:

Turn off the power supply and unplug the power cord of the

ATX power supply before connecting to ATX PW connector.

The Motherboard requires a power supply with at least 250 Watts and a "power good" signal. Make sure the ATX power supply can take at 1.5 A max current * load on the 5V Standby lead (5VSB) to meet the standard ATX specification.

Note:

 ATX 12V power supply is different from the normal ATX power

supply.

 If you use the Wake-On-LAN (WOL) function, make sure the

ATX power supply can support at least 720 mA on the 5V Standby lead (5VSB).

more info on how to clear the CMOS).

4. Make sure the power supply you have on your system support the

M/B specification. Example. If you have a P4 M/B, you need to use

a P4 power supply.

5. If you already checked the power supply specification, change the

power supply it might be defective. The minimum is 250 watts.

When I boot up my system, everything works fine, it sees my CPU and

memory, detects my hard drive, floppy drive and CD-ROM but locks

up at "Verify DMI pool data... ". Don't go any further. What should I

do?

1. Clear CMOS battery. (JP5 connector, see Quick start guide for

more info on how to clear the CMOS).

2. If still has the problem, remove all other add-on cards except video

card see if it move further. Then put peripherals in one by one to

identify which one cause the lockup.

3. Change the CPU.

During Boot-up, my computer says CMOS memory Checksum error.

What is the problem?

1. Clear CMOS memory.

2. Re-flash BIOS. Check on how to flash BIOS on the later part of

this book.

3. Change the CMOS battery, the battery might be drained.

Memory/ Video card/Hard disk. See if you can finish Windows

installation. Then put peripherals in one by one to identify which

one cause the lockup.

My system will not boot-up when I set my CPU to 133MHz FSB, works

with 100MHz FSB

1. Make sure to put some thermal paste above the CPU.

2. CPU might be defective.

BIOS Issue

Where can I find the BIOS revision of my mainboard?

It will be displayed on the up-left corner on the screen during boot-up. It will

show as your board type followed by the revision number, such as

kvxa_2BA1 (meaning BIOS revision 2BA1 for the SY-K7V Dragon plus!

board) or 6BA+ IV_2AA2 which means SY-6BA+ IV motherboard with

2AA2 BIOS.

Where can I find the latest BIOS of my motherboard?

Please go to the technical support page of one of the SOYO websites

(Taiwan: www.soyo.com.tw

), and look up your motherboard to find the

latest BIOS revision.

How can I flash the BIOS?
