Step 3. Configure Memory
Your board comes with two DIMM sockets, providing support for up to 512MB of main
memory using unbuffered and registered DIMM modules from 8MB to 256MB. On this
motherboard, DRAM speed can be set independent from the CPU front side bus speed.
Depending on the DRAM clock speed setting in the BIOS setup, appropriate memory
modules must be used. For 66MHz DRAM speed, use PC66 memory; for 100MHz DRAM
speed, use PC100 memory; for 133MHz DRAM speed, use PC133 memory.

Note:Always install memory modules in the order prescribed in this table.
CMOS Clear (JBAT1)
In some cases the CMOS memory may contain wrong data, follow the steps below to clear
CMOS memory.
1. Clear the CMOS memory by momentarily shorting pin 2-3 on jumper JBAT1. This
jumper can be easily identified by its white colored cap.
2. Then put the jumper back to 1-2 to allow writing of new data into the CMOS memory.

The SOYO CD
The user's manual files included on the SOYO CD are in PDF (Postscript Document)
format. In order to read a PDF file, the appropriate Acrobat Reader software must be
installed in your system.
Note:
The Start Up program automatically detects if the Acrobat Reader utility is already
present in your system, and otherwise prompts you on whether or not you want to install it.
You must install the Acrobat Reader utility to be able to read the user's manual file. Follow
the instructions on your screen during installation, then once the installation is completed,
restart your system and re-run the SOYO CD.
Step 2. Install Drivers and Utilities
Click the

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 get distorted video right after I save my bios. Why is that?
To fix this, please clear the CMOS via JBAT1 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

SY-7VEM Quick Start Guide
16
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 via 4 in 1 driver from the SOYO CD, this is because Windows does not
properly recognize relatively new chipsets.
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 'via 4 in 1' 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 'via 4 in 1' driver for the
motherboard.

SY-7VEM Quick Start Guide
17
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 JBAT1 then choose 'load optimized 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.
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:
