XGP1: Xtreme Gr aphics Port Slot
This XGP (Extreme 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 dr iver i nstallat i on. If the on bo ar d VG A dr iver has a lready bee n
installed before you install the add-on AGP VGA card, the system
will automatically set the onboard VGA as the primary graphics
adapter.
For the onboard VGA driver can’t be removed com pletely, and to
solve thi s problem, please follow the steps bel ow,
1. Disable onboard VGA utility under the operating system, and
reboot PC. After PC restarts, the system will automat ically set
the AGP V GA car d as the graphics a dap ter .
2. Or, re-i nstall your operating system to ensure the AGP VGA
card function can be used.
