Can't I just use device manager to disable old onboard graphics?

I'm getting ready to install an XFX Radeon 5670 graphics card in my home built PC. It will replace the onboard graphics card. The installation guide says go in BIOS or use jumper switches to disable the old onboard video.

I would rather not mess with with jumpers or BIOS. When I did this in the past, I just went into the OS device manager and disabled it there. Is this not sufficient?

Thanks,
Dave

It depends on how the onboard video is designed. A few like Intel 810 can't be turned off and you have to disable from Device Manager. But it does relinquish Primary Adapter status to the alternative video card. Some designs may not do this, so if you don't turn them off in the BIOS, or change the Primary Adapter designation, the POST screen can still be sent to the onboard card, so the computer screen will be blank until Windows boots, and no POST prompts or error messages will appear. But the main reason for disabling the onboard in the BIOS is to claim back system memory it would otherwise be allocated. That's part of the reason to move from onboard graphics, if you miss out on reclaiming its RAM usage you'll miss out on that part of the performance enhancement you're seeking.

It's usually best to disable the on-board graphics using the BIOS, if possible. In most BIOS' there is usually an option that says something like "Onboard Video {ENABLE/DISABLE}." Just change turn it off and you're set. If you never plan on using it again, remove then reinstall the drivers to make sure it is gone for good.

My motherboard is:

ASUS M4A78LT-M-LE AM3 AMD 780L Micro-ATX. The onboard graphics is ATI Radeon 3000. I am replacing that with a stand-alone ATI Radeon 5670.
