Question : Problem: How to disable onboard video on Jetway P4MFM motherboard?

Here's the problem. I recently got a new video card. It works fine, except for a few small problems that I suspect have to do with me not properly disabling my onboard video. I have no idea how to this. The manual doesn't help at all, there is no mention at all about this procedure. I've searched through Google several times looking for a solution, but I've turned up with nothing. If anyone could help, I would be very thankful. Again, my motherboard is a Jetway P4MFM. Any other information you need, just ask.

I've checked your manual and your motherboard's jumpers, and no, you're right, there's no way to 'disable' the onboard video.

My suggestion would be to disable the display in your device manager.  Both the new and the old display adapter are probably listed there.  Right click on the old one and disable it.
