So, I built a PC using a PCCHIPS P21G (v3.1) motherboard. I wanted to go with a dual monitor setup, so I also installed my ATI All-in-wonder 9700 in the AGP slot. However, when I install windows the integrated video is nowhere to be found.
I did some research and found out that the "S3 UniChrome Pro" graphics is built into the northbridge of the P4M800 VIA chipset on the motherboard. I updated the VIA drivers and tried to install the S3 drivers, but the installation program says that no compatible hardware is found.
I suspected that maybe the onboard video gets disabled when an AGP card is detected. I carefully looked through the BIOS for any option relating to this and found nothing. The closest thing I could find was the "Primary Video Card is AGP/PCI" option, and I don't think that has anything to do with it (I tried it anyway, just in case). So, to test my theory I yanked my ATI and rebooted, and voila! The other monitor turns on and WinXP realizes that the integrated video exists. I say "well, that's a start" and successfully install the S3 drivers. However, as soon as I put the AGP card back in, the onboard video disappears as if it had never been there in the first place.
Anybody have any suggestions?
