You should be able to disable on board devices in the BIOS on most systems but I don't know your system. You will need to disable this some way in order for an add in device to work without problems especially if there are shared resources. If the on board video is connected to the chipsets AGP subsystem, only one device can use it. Search the BIOS thoroughly for the option to disable it. Next, I also have a Radeon 9200 card in one of my systems that had problems with XP. I found it to be finiky with drivers and that a series of newer drivers from about Oct. of 2003 forward did not allow the PC to boot properly. I needed to use older drivers from about last August. The package from this June seems to be ok but don't discount the possiblility that you may need to monkey around with ATI drivers. First, though, keep trying to disable the on board video. Good luck.
Im not very good with computers. I know my way around em, but i dont know in depth things. i cant run multiple games i have bought, so i checked the requirements and i bought a radeon 9200 (it had morphing and lighting, that was what i needed)
i have a gateway 500s with windows XP and intel 828456g/gl integrated graphics. now, i believe you cannot disable it at the mother board, if there is a way, please correct me. i have installed the ati card and my system is reading it, but when i install the driver, there is an error. my guess is that the intel integrated is trying to block it. i have tried removing the driver in control panel and in the device manager in both normal and safe mode but it seems that it has popped back up and is preventing my ati card from being used... can anyone PLEASE help me?
