Onboard VGA Disabling Problems

Recommended by Wim's BIOS...

I have a ECS M925 mother board (Bios Agent said that) I would give you more info. but i cant right now. I was trying to install a AGP graphics card on my motherboard but I learned that I have to disable the on board VGA (after finding that plugging the new video card in didn't do anything) so i went into the bios changed some settings then i turned the computer off then back on and found out nothing appears on the screen using the onboard VGA and agp card.

I want to know if i can reset the bios on this motherboard by switching pins around and if so which pins.

thanks in advance
