2.7 Installing an expansion card
In the future, you may need to install expansion cards. The motherboard
has one PCI and one Accelerated Graphics Port (AGP) slot. The following
sub-sections describe the slots and the expansion cards that they support.
2.7.1 Expansion slots
PCI slot
The PCI slot supports PCI cards such as a LAN card, SCSI card, USB
card, and other cards that comply with PCI specifications.
AGP slot
The AGP slot supports AGP 8X/4X cards. When you buy an AGP card,
make sure that you ask for one with +1.5V specification.

Make sure to unplug the power cord before adding or removing
expansion cards. Failure to do so may cause you physical injury and
damage the motherboard.
Install only +1.5V AGP cards. The P4R8T motherboard does not
support 3.3V AGP cards.
