3.5 Expansion Slots
This motherboard contains 4 expansion slots. One AGP, one ATX Riser and two 32-
bit PCI expansion slots.
AGP Expansion Slot
The Accelerated Graphics Port (AGP) is a high performance interconnect targeted at
3D graphical display applications and is based on a set of performance extensions or
enhancements to the PCI bus. (AGP interface specification Rev. 2.0 compliant.)
Note: The motherboard supports AGP 1X/2X/4X mode.
To install expansion cards, please read the expansion card’s documentation for
instructions and cautions.
PCI Riser Slot
This supports ATX Riser card through the PCI Riser connector. The PCI Riser card
specification defines a riser card that can be used with any board form-factor in the
ATX family to achieve a low-cost, low profile system design. With the addition of a
2x11 connector to a PCI connector on a standard ATX-family desktop board, the
board can be used in multiple system designs or with the riser card as a low-profile
desktop. This design reuses saves research and development time as well as
inventory costs.
Market trends indicate a continued need for space-constrained systems in corporate
application such as business client and point-of-sale as well as new consumer
applications. The transition of low-profile designs from the LPX form factor to the
NLX form factor confirmed the market need for these low-profile systems. The intent
of this specification is to outline one possible approach to a cost-effective, low
profile desktop using commonly available form factor building blocks. The riser
specification allows the low-profile market to take advantage of the most popular of
form factors available: ATX.
PCI Expansion Slots
All PCI expansion slots accept PCI bus master cards and are fully supported by the
PCI 2.2 specification.
