On-Board video adapters

[Guest_imported]

I have an old Acer Aspire - not sure on exact model - and the video adapter is built onto the motherboard. I have a better video card to put in but I need to know how to disable the video adapter that is built-in. There is nothing in cmos setup that allows you to disable the on-board device.

to me onboard vga is a big no no , when looking for a board to buy, in any case your board , if it's not in the CMOS setup, I would think it's a dip switch or pins on the board, goto Acer website and see if they have any online manaual (or check your manual if you still have it) if you dont know the model of your board, we cant help you much, and it would be harder to find the manual online. Also in the BIOS you may want to try changing something like Init PCI First, or Init AGP First, and trying the card anyways, the presense of a video card may or may not override the existing onboard componet.

It's been my experience that this will be controlled via a jumper on the mother-board. Use Karl's instructions to locate the specific jumper, but if that fails, you may just luck out by finding the slot bracket with the 15 pin video connector, and trace it back to the header on the m-bd that it is plugged into. Usually, the jumper is in close proximity to the VGA feature header.

Once you get it turned off, leave it so. Most on-board video setups use a pooled memory, meaning that it will use some of your RAM for video memory. So if you have 64 MB installed, but Windows reports only having 60, your on-board video adapter has taken that other 4MB before windows loads.

Hope this helps!!!
