Help Disabling Onboard Video!!

[chrislong]

Hello Everyone
I need a bit more help from some of you people with long memories...I have an video card upgrade planned on a friend's HP Pavilion 8240, and I'll need to disable the onboard video to do it (at least I think I will!) Does anyone know how this is done on one of these machines? Is it done physically on the motherboard (switches, jumpers, etc), or is it a selection in the BIOS setup?

The upgrade will be to a PCI video card with at least 8MB ram, as opposed to the whopping 1Mb on the board!! lol Still undetermined as to which card, but whatever I get for him will be a great improvement. Might be a Voodoo3 2000. Anyway......

Also, I'm interested in any advice on the proper steps in the procedure; i.e. do I install the 'new' card first, then boot and disable (if it's a BIOS thing) or do I disable the video and install the card after I've done that (if it's a mechanical switch, etc on the board). I'm a little uncertain about it all, and I don't want to end up with a blank screen--especially since it's not my computer!!

Here's a ridiculously long link to the motherboard layout and jumper settings, if that helps...

By the way he's running Win 95 (one of the last ones)...

Thanks a bunch!

go into the BIOS and look through every part to see if you can find a setting like 'Disable Onboard Video'.

If can find this, then you're sorted, just set it to disable, save and exit BIOS. Wait about 5 seconds and then switch PC off. Insert new video card, plug in monitor cable and your away!

if however, its not in the BIOS, you will have to look very closely on the motherboard to see what jumper contols the onboard video. there should be writing on the board (very small) that says something like onbrdvid (guess). then change the jumper from position 1-2 to 2-3, or whatever way moves it from its current position.

good luck

btw. it may be that VGA IRQ jumper on the link u posted. look for anything else first though.
