PCI Express Slots

The PCI Express slots, as a
high-bandwidth, low pin coun
interconnect technology.
PCI Express architecture p
high performance I/O infrastructure fo
Desktop Platforms with transfer rates
starting at 2.5 Giga transfers per secon
Tuners, 1394 controllers, and gen
Architecture will be designed to deliver highest performance in video, graphics, multimedia
other sophisticated applications. Moreover, PCI Express architecture provides a high
performance graphics infrastructure for Desktop Platforms doubling the capability of existing
AGP 8x designs with transfer rates of 4.0 GB/s over a PCI Express x16 lane for graphics
controllers.
You can insert the expansion cards to meet your needs. Wh
cards, make sure that you unplug the power supply first.
Note:
System default is to disable the onboard VGA when you insert a PCI-E graph card, in order to
optimize the system performance. If you would like to use both onboard and expansion card
graph functions, you have to enter the mainboard BIOS and select Advanced Chipset Features
-> OnChip and PCIe VGA selection -> Both exist and Oncip VGA by frame buffer select.

PCI (Peripheral Component Interconnect) Slots

The PCI slots allow you to insert the expansion cards
to meet your needs. When adding or removing
expansion cards, make sure that you unplug the
documentation for the expansion card to make any necessary hardware or software settin
the expansion card, such as jumpers, switches or BIOS configuration.

PCI Interrupt Request Routing

The IRQ, abbreviation of interrupt request
which devices can send interrupt signals to the microprocessor. The PCI IRQ pins are typically
connected to the PCI bus INT A# ~ INT D# pins as follows:
