There is nothing in the BIOS relating to AGP or even PCI for that matter, and I can't even disable the onboard graphics.
The computer is an E-Machines model W4685
Windows XP Professional
Mainboard : First International Computer, Inc. (VG33)
Chipset : Intel i845GE
Bios : Phoenix Technologies, LTD
Manufacturer : Phoenix Technologies, LTD
Version : IEX423EM
I will post any information that you need about my computer, so just ask. I would appreciate any help! (The information above is taken from a program called PC Wizard 2005)
