Hardware Installation

SY-7VCA2

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 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
