Howdy!
I don't know whether anyone can really help me here
Here's the thing. My motherboard is a MSI "MS-6168", socket Intel 440BX/ZX (Intel through this socket reportedly discriminated against AGP by omitting an AGP port, but also against PCI graphics cards, in the way I'm concerned: I can't disable the onboard graphics controller).
There's a '3dfx Voodoo3 2000 8MB' embedded board supposedly AGP. In fact there's a 2X AGP bus on the motherboard (no AGP port). Because I wanted to upgrade my graphics capabilities, I bought an ATI Radeon 9000 64MB on PCI port. The issue though is that I need to wait 5-7 minutes before rebooting my computer, otherwise the new graphics card sort of comes into conflict with the onboard graphics controller and also the Windows driver for the ATI card is not loaded, and the display comes off very bad, 60hz refresh rate...
There is no apparent BIOS option to modify in order to fix this. I just know that whenever I don't wait long enough, there's the word "update" that appears at the end of the second line in the BIOS booting phase, right before Windows XP loads, looks like as if I'd modified something in the BIOS but I'd just started the computer.
If I waited long enough and in order to use the Radeon as my main display device, I had to disable the AGP/PCI bridge in Windows XP device manager (also suppressing the Voodoo from the list).
If ever you got any suggestions or questions, please do not hesitate to contact me. So far I have never run into anybody having the same symptoms.
The whole thing has really been giving me a royal pain, mainly because I can't restart my system, but rather have to turn it off, wait 7 minutes or more and then turn it back on and it's getting old.
