MS-5191 : Disabling the onboard AGP

[zaprobo]

Hiya,

I have an old K6-2 500MHz machine with the above model of motherboard.

I've just installed a new (well, for me anyway! ) PCI GeForce2 graphics card and the onboard AGP is conflicting with it. Not enough that it stops the PC being used, but enough that OpenGL will not function.

I've downloaded the motherboard manuals but nowhere can I find how to disable the AGP. Nothing about jumpers and nothing in the BIOS either.

Can you help please?

The only way is to disable it from the Device manager in the OS.
This way it will not use up resources and is effectively not present.



To be on the safe side try reinstalling directX (8.0 or above) and then the VGA driver (28.32 work wel for me).

Fair enough, and I'd already attempted this.

However, msinfo32 reports the following...

As you can see XP thinks (on some level) that the GeForce is really the ATI card. While it performs perfectly normally under Direct3D it hits the sticking point on OpenGL and dies.

I've tried deleting the problem drivers (two *ati* files and an old 3dfx one) but Windows File Protection steps in an replaces them!

Any further advice would be appreciated (short of reinstall XP).

Regards,
Andy

If you are not prepared to go into the registry and do a 'bit' of housecleaning (like what should be done on a video card switch) then you hit the nail on the head:

(reinstall XP).
