disabling integrated video after its shot?

I had an emachine t1115 go bad on me this morning blue screen of death, I set it back to the factory default from cds before I had read how to make an xp boot disk here. Anyway when I took it back to the users desk the video didn't work, then back to my work bench and the same result. The video was integrated, I had an old pci video card laying around put it in but it didn't work. Was wondering is there anyway to disable the integrated video from the bios without being able to see it. the motherboard is an lm810e. Its not a strong machine but worked for what we needed it for. I would hate throw this thing away since all it needs is a video card. By the way I did get the 4 beeps which if I remember correctly does signify bad display adapter.

Any help would be greatly appreciated.
