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
In some cases BIOS upgrade might be required to take advantage of this new feature. Please refer to our

Quick Start Guide
Increased +12 VDC output capability. Mother board components with unique voltage
requirements are increasingly expected to be powered via DC/DC converters off the +12 VDC
power supply output. This trend is due primarily to the higher power conversion and transmission
efficiencies of +12 VDC relative to +5 VDC or +3.3 VDC. ATX12V power supplies should be
designed to accommodate these increased +12 VDC current requirements and to address
associated issues such as cross-regulation, capacitive loading, transient surge tolerance, cable
voltage drop, and cooling.
New +12 V power connector. To enable the delivery of more +12 VDC current to the
motherboard, a new 4-pin receptacle/header combination--the + 12 V power connector–has
been defined.

After flashing the BIOS, my system will not boot-up.
1. Try clearing the CMOS.
2. The BIOS chip is defected due to unsuccessful flash, contact your nearest SOYO branch for
re-flashing.
Is there a way to reprogram my BIOS after an unsuccessful flash?
No other way, you need to send back the BIOS ROM to your nearest SOYO branch for re-flashing.

Quick Start Guide
The sound is working in my system, but when I play CD music from the CD-ROM, I
do not get any sound. What is wrong?
This is because the 3-wire audio cable from the CD-ROM to the on-board CDIN1 connector in the M/B
is not connected. See manual for location of CDIN1.
The sound from my sound card is distorted when Windows start. What is wrong?
If you are using an ISA sound card, please make sure the IRQ needed for the sound card is set to 'Legacy
ISA' in the BIOS. In other word, if your ISA sound card takes IRQ5, then set IRQ5 to 'Legacy ISA'.
The sound and everything else works fine except that the recorder and microphone do
not work. What is wrong?
1. Please go to sound properties and check if the recorder and microphone in the are enabled.
2. Check if Microphone is ok.
The sound coming from my Center and Base speaker is interchange, what should I
do?
Set the JP1 and JP2 of the small audio card to pin2-3.
Hard disk/FDD/ CD-ROM issue
My Western digital HDD is not detected during boot-up
Change the jumper settings to cable select or single.
Sometimes the system finds my CD-ROM, sometimes not
1. Check CD-ROM if it is working properly.
2. The power supply might not have enough wattage to support all the peripherals. If your
system has other peripherals connected, like CD-RW, extra HDD, etc. disconnect them.
When I boot up my new computer I got "floppy boot failure" and the LED on the
floppy stays on
Make sure the red wire of floppy ribbon cable goes to Pin1 on the floppy drive side (don't
trust the "key lock" or "notch") and use the end-connector of the cable (don't use middle one).
