Hi all,
lets see where to start, a friend of mine reinstalled windows on his compaq pc, and now the agp slot is disabled. and there is no setting in the bios for the agp slot so it wont recognize any vid cards.
computer is a compaq presario 5900z, I checked the compaq site for a bios update but they have none for that model

specs i got from the bios agent program

Program: eSupport.com BIOS Agent Version 3.42
BIOS Date: 10/15/99
BIOS Type: PhoenixBIOS 4.0 Release 6.0.6
BIOS ID: Compaq PC X2.0 9944CMPZK360
OEM Sign-On: None
Chipset: AMD 751 rev 35

OS: Win98
CPU: AMD-K7(tm) Processor 698 MHz

my question is will a bios update fix this? and where can i find one?
I've been looking for 2 days with no luck
any suggestions as to the problem? or why it did this?
thanks in advance

You need to install AMD chipset drivers - The Win98 AGP driver

When you re-installed Windows, did you have the AGP card in the slot. This problem sounds strange but the only circumstance I can think of where the AGP slot may be disabled is if Windows was installed with a PCI VGA card. I find it better to have the card in the machine that you want Windows to work with when you install Windows.

Also, I am assuming that this is actually an O/S problem. It sounds like it. For example, if you put in the AGP VGA card then you will get the BIOS messages on the screen before Windows loads - is that correct?

Win98/98SE does not have chipset drivers for AMD 75x (or newer) chipsets so all AGP VGA will run in PCI compatibility mode
