Best way to add AGP video card on Intel 815 mobo?

[techs]

If a board has both the onboard intel 815 graphics and an AGP slot what is the best way to add an AGP card. Should the 815 graphics driver be uninstalled then the AGP card installed and its drivers installed? Or should the 815 drivers be left installed?

I don't have an Intel 815 mobo so you might want to consult your technical manual for support, or contact Intel directly.

However just based on my experience you are talking about two separate video cards. I really don't think you need to uninstall the onboard video drivers because when you add AGP you are switching to an entirely different video system.

I would simply make sure your video card is switched to the AGP card you've added in the BIOS, not your previous onboard drivers.

For example my mobo has onboard AGP and an AGP slot. The problem is that the onboard AGP is lousy so I bought an extra NVidia AGP card. Then I had to switch my bios settings to PCI, allocate and IRQ, and then I was good to go.

If you don't know how to do this you should contact your manufacturer.

Good Luck,

It depends what you want to achieve and what the bios will allow...

If you want to set up dual monitors, then leave the drivers in place. However, the 815 might be one of those that automatically disables the onboard video when it detects the agp slot in use, so you may not have a choice...

To be safe then, go to safe mode and change the onboard display adapter to a standard pci vga adapter.

Reboot to make sure it has worked - you will see only 16 colours...

Shut down and go into the bios to see what your options are. If you have the option to enable irq for vga, make sure that is enabled. If you have the option to choose between PCI and AGP video on boot, choose AGP.

Shut down again and add your new card. Cross fingers and boot to normal mode. Good luck

I should have mentioned this but what I was wondering is whether the on board graphics driver adds any chipset support that will be needed for the add in card. Not a critical issue, just wondered if anyone had read anything with a specific recommendation from Intel.
