Solved BIOS change made screen black

Black screen on Shuttle SG41J4 after BIOS change
I am setting up a Shuttle SG41J4. When looking at the BIOS settings, there was an entry: Initiate Graphic Adapter", and the setting was "PCI". I changed to "PCIe" for I want to use the PCI for an AD/DA card. After this action, the screen remained black at reboot...
Any idea what to do besides borrowing a PCIe graphics card just to reset the BIOS?
BIOS is an AMI, I cannot look at the version because of above act...

Thanks
Rentier

✔ Best Answer
You can clear the CMOS by moving a jumper on the mobo for a few seconds and putting it back.

That was it! Grat thanks! (indeed on the Shuttle there is no jumper, but a hidden switch on the back side. Not mentioned in the manual, but shown on the board overview).

If it is fixed, then remember that there is a clear CMOS button and if you do something wrong in the BIOS then clear CMOS, and your welcome.

" changed to "PCIe" for I want to use the PCI for an AD/DA card. After this action, the screen remained black at reboot... "

Which AD/DA card ?

Did you plug that into the PCI slot before you started up the computer again ?
If yes, remove the AC power to the computer, remove the AD/DA card, then try booting the computer - you will probably have video.

You DO NOT need to change the Initiate Graphic Adapter setting in the bios Setup unless you have a PCI-E video card installed in the PCI-E slot, and even then, with your mboard's main chipset, changing that setting in the bios almost always has NO EFFECT regarding whether you get video while booting the computer or in Windows itself (unless you're using Windiows ME or previous).

However, a problem caused by installing the AD/DA card COULD cause no video.

Support List tab - Graphic Card Support List

Lists ONLY PCI-E cards

"Caution: Due to some of high-end graphics cards require higher power consumption, please refer our 'Power Supply Calculator' to check what kind of power supply need to upgrade. "

I know from experience with another XPC system that SOME of the cards listed are NOT supported unless you replace the power supply with an optional one, or a clone generic power supply, that has more wattage capacity.

..............

If your AD/DA card requires that the system has a power supply with a capacity of greater than 250 watts, your system may NOT boot.

The PCI slot closest to the center of the mboard if you have more than one (in this case you have only one) usually shares it's IRQ with the video adapter, whether you're using the onboard video, or a video card installed in the PCI-E sot. If you install a PCI card that is not a PCI video card in that slot, you're likely to have problems.

Apparently some PCI AD/DA cards can be forced to try to use a different IRQ.....

e..g.
http://www.pciadda.com/manual/manua...

......but that may not work when your card is installed in that PCI slot.


If you ALSO have a PCI-E video card installed in the PCI-E slot, your power supply may NOT have enough capacity to support both the power requirements of the PCI-E card's video chipset and the PCI AD/DA card, in which case the computer will probably NOT boot when both are installed.

There's not much info in the Manual for XPC systems - the Quick Guide shows you a lot more detail.

You need to interrupt the power to the computer before clearing the CMOS.
