Biostar T-Series Xtreme Graphics Port Slot: XGP1 This XGP (Xtreme Graphics Port) slot is a special design that only supports compatible AGP VGA cards. To install the system with an add-on AGP VGA card, please make sure to install the driver of add-on AGP VGA card before onboard VGA driver installation. If the onboard VGA driver has already been installed before you install the add-on AGP VGA card, the system will automatically set the onboard VGA as the primary graphics adapter. If the onboard VGA driver can't be removed completely, and to solve this problem, please follow the steps below: 1. Disable onboard VGA utility under the operating system, and reboot PC. After PC restarts, the system will automatically set the AGP VGA card as the graphics adapter. 2. Re-install your operating system to ensure the AGP VGA card function can be used.
