Code Explanation
X X X
L
D8 D3 D2 D1
Initialization of the chipset. The MCH and ICH registers will be set to the most
conservative values by the BIOS to make sure the system boots up properly.
X X LX
D8 D3 D2 D1
The BIOS is now decompressing the BIOS code into shadow RAM. Most of
the BIOS code is stored in the BIOS Flash ROM IC in compressed form to
save space. At boot-up this code is decompressed and stored to RAM for faster
execution.
X X L L
D8 D3 D2 D1
The checksum for the decompressed code is calculated and checked. The
checksum is calculated by adding all data bytes together and storing the result
in the BIOS ROM. If the calculated checksum is different from the checksum
stored in the ROM, the code stored in the FLASH ROM is corrupted.
XLX X
D8 D3 D2 D1
The chipset (MCH and ICH) registers are set to the values selected by the user.
XLXL
D8 D3 D2 D1
Now the BIOS will set the CPU Vcore voltage and the FSB bus frequency to
the user selected value. If the system stops at this point, the settings selected by
the user are inappropriate. Please select more conservative settings.
XL L X
D8 D3 D2 D1
The Hardware Monitor Functionality is initialized. The settings the user
selected in the BIOS for the Hardware Monitor are written into the Hardware
Monitor registers.
XLLL
D8 D3 D2 D1 If the VGA card does not work or is not inserted at all, the system will display
this code for a short period of time.
LXXX
D8 D3 D2 D1
At this point the BIOS is initializing the CPU. The L2 cache latency values are
set, and more important, the CPU micro-code is written into the CPU.
LX X L
D8 D3 D2 D1
Now the system is testing the RAM inserted on the board. The screen will
show the BIOS testing the RAM by a running counter. After finishing the test,
the screen will show the amount of RAM in your system.
LXLX
D8 D3 D2 D1 The super I/O registers are set to the default values. This includes the serial,
parallel and IR etc settings.
LXL L
D8 D3 D2 D1
At this point the IDE busses (primary and secondary) are scanned for devices.
This includes HD drives and ATAPI CD-ROM drives that are connected to the
IDE bus. After scanning the detected devices are displayed on screen.
L L X X
D8 D3 D2 D1 The serial and parallel port registers are set to the values selected by the user.
L L XL
D8 D3 D2 D1
Now the BIOS will scan the peripheral busses for add-on cards. This includes
the PCI and AGP busses. If any add-on cards are detected, the resources it
requires are assigned by the BIOS in accordance with user settings.
L L L X
D8 D3 D2 D1
The ESCD and DMI (Desktop Management Interface) values are checked. If
there are changes, the BIOS will flash the new values into the BIOS Flash
ROM IC.
L L L L
D8 D3 D2 D1
At this point the BIOS passes control to the Operating System (OS). All LEDs
will be on and will stay on to indicate a successful boot.

Quick Trouble shoot tips
Video (no display) related issues
I built a new computer system using a Soyo board and nothing happens when
turning it on, no video and no beeps from the PC speaker. What is happening
and how can it be fixed?
No screen and no beeps mean that your CPU and motherboard do not work at all. It
could be that the CPU is not seated correctly or that a component on the M/B is
grounded (shorted) with the case. Also make sure to check the voltage setting
switch (110V/220V) on the back of the power supply. To isolate the problem do
the following:
1. Press and hold down on the “Ins”(insert) key while turning on the computer
until you get video. If you do not get video then,
2. Double-check jumpers setting on you motherboard and remove all add-on
cards, unplug all hard-disk and floppy-disk drive cables and see if you can hear
some beeps. If you still do not get any beeps, then try putting the motherboard on
the table (to isolate it from the case) with the CPU and speaker only, and give it one
more try.
I hear a series of beeps and I do not get anything from my monitor. What
could be wrong?
The following lists some basic beep codes and their possible meanings:
•One long beep and 3 very short beeps - The video card is not detected by
the motherboard. Please re-seat your video card. If you are using an AGP
card, please push your AGP card down real hard. You may have to push
VERY hard without the AGP card mounting screw. Make sure not to
insert the card the other way around.
•Continuous beeps –One or more of the memory modules is not seated
correctly in its socket.
My PCI VGA card works fine with my system, but when I put in a new AGP
card, it does not give me any video. Is my AGP slot bad?
This is a common problem with AGP video cards. The reason is that your AGP
card did not get seated into the AGP slot fully and firmly. Please push your AGP
card down into the socket real hard, it should snap twice. You may have to unscrew

SY-7VCA Quick Start Guide
17
the AGP card to allow the card to go further down. Do take care not to damage the
card by using too much force.
I get distorted video my AGP card right after I save my bios. Why is that?
The cause is likely that your AGP card is not running at the correct bus speed. To
fix this, please clear the CMOS via JP5 and if it still does not work, please upgrade
your motherboard bios to the latest version.
BIOS Issues
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 5EH_2CA1 (meaning
revision 2CA1 for the SY-5EH 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.
Hard disk, floppy drive, CD-ROM etc
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).
Modem issues
I get an "I/O Conflict" message when I turn on my system and I can not get
my modem to work
What you need to do is to disable 'COM2' (or UART2 or serial port 2) in the bios
under integrated peripheral setup.
I have installed my modem drivers several times and I still cannot get my
modem to work. Why?
If you are sure that the modem driver has been installed correctly, then you need to
install the south bridge driver from the SOYO CD, this is because Windows does
not properly recognize relatively new chipsets.

SY-7VCA Quick Start Guide
18
Audio Issues
I do not get any sound from my sound card. What could be wrong?
Please make sure the speaker is connected to the speaker out port on your sound card.
In Device Manager, I keep getting yellow exclamation signs on my sound port
even though I have installed my sound driver several times and I could not get
my sound card to work. What is wrong?
It is likely that you did not have the correct driver installed. If you are sure that the
correct sound driver has been installed, then please install the 'south bridge' driver
for the motherboard.
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 sound card is not
connected or it is loose.
The sound from my sound card is distorted when Windows starts. What is
wrong?
First, 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 words, if your ISA sound card
takes IRQ5, then set IRQ5 to 'Legacy ISA'. Next, install the 'south bridge' driver for
the motherboard.
The sound and everything else works fine except that the recorder and
microphone do not work. What is wrong?
This is because the recorder and microphone in the Windows are not enabled.
Please go to sound properties and enable them.
Lock up (freeze)
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... ", and it won’t go any further. What should I do?
Please clear the CMOS via JP5 then choose 'load setup default' in the bios and save
the bios and exit. Next, unplug all other add-on cards except the video card and
floppy drive controller, and see if it can boot from floppy. Then put back the
peripherals one by one to identify which one causes the lockup. If you are running a
Cyrix CPU, make sure the 'linear burst function' is enabled in the bios.
I can not get my board to run properly.
Please make sure you have the latest bios and driver from the SOYO web site at:
