Front Audio Connector: FRONT AUDIO
If your PC front panel has the audio ports, please remove the jumpers on this header, and
then you will have two sets of audio ports (one set is on your PC front panel and the other
one is on your PC back panel) to use. On the other hand, your audio ports on the PC back
panel will fail to work if the jumper caps on this header are removed.

Slots
This mainboard provides two PCI-Express x16 slots for graphics cards used and two PCI
slots for expansion cards used.
PCI-Express slots: PCI-E4, PCI-E5
The PCI-E4 and PCI-E5 are two PCI-Express x16 interface slots, which are able to support
x16 and x4 mode in individual, and also support users to insert two dual graphics cards for
multiple display. Via the Bridge Card setup (
See Appendix III
), the PCI-Express
performance and efficiency can essentially be enhanced largely.
PCI Slots: PCI1, PCI2
This mainboard provides two standard 32-bit PCI slots. PCI stands for Peripheral
Component Interconnect and is a bus standard for expansion cards, which has supplanted
the older ISA bus standard.
