2-3-4. Installing Add-on Cards

The slots on this motherboard are designed to hold expansion cards and connect
them to the system bus. Expansion slots are a means of adding or enhancing the
motherboard's features and capabilities. With these efficient facilities, you can
increase the motherboard's capabilities by adding hardware that performs tasks
that are not part of the basic system.
PCIEX16_1~3 Slot The PCI Express x16 slots are used to install external PCI Ex-
press graphics cards that are fully compliant to the PCI Express
Base Specification revision 3.0.
PCI1~2 Slots This motherboard is equipped with two standard PCI slots. PCI
stands for Peripheral Component Interconnect and is a bus
standard for expansion cards, which for the most part, is a
supplement of the older ISA bus standard. The PCI slots on this
board are PCI v3.0 compliant.
The PCI Express x1 slots are fully compliant to the PCI Express
PCIE1_2 Slots
Base Specification revision 2.0.
Before installing an add-on card, check the documentation for
