Disabling onboard Graphics

I posted the thread at the Albratron section, but not many replies, although this might be more general.

I'm trying to help someone over the net, but I'm not familiar with the person's motherboard. He owns a Albratron KM18G nForce 2 mobo, and just recently bought a new graphics card Radeon 9600. Prior to that he was using the onboard graphics. Since I'm not familiar with the options on his BIOS, can you tell me which option is he suppose to disable for the onboard graphics so that he can use his Radeon 9600 card?

I think he's using the Phoenix BIOS, so what option should he turn off, where is it located? Thanks, I don't have a system with integrated graphics to look for the option.

Folks in the Video Cards, Editing and Displays forum will be able to set you right up.

Generally, most on-board graphics will automatically disable when an AGP card is detected at boot.

You would also want to uninstall the drivers and remove the graphics adapter from the device manager prior to shut down for the new card install.
