PCI Express Slots
The PCI Express slots, as a
high-bandwidth, low pin count, serial,
interconnect technology.
PCI Express architecture provides a
high performance I/O infrastructure for
Desktop Platforms with transfer rates
starting at 2.5 Giga transfers per second over a PCI Express x1 lane for Gigabit Ethernet, TV
Tuners, 1394 controllers, and general purpose I/O. Also, desktop platforms with PCI Express
Architecture will be designed to deliver highest performance in video, graphics, multimedia and
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. When adding or removing expansion
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 power supply first. Meanwhile, read the
documentation for the expansion card to make any necessary hardware or software settings for
the expansion card, such as jumpers, switches or BIOS configuration.
PCI Interrupt Request Routing
The IRQ, abbreviation of interrupt request line and pronounced I-R-Q, are hardware lines over
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:
Order1
PCI Slot 1
INT B#
PCI Slot 2
INT C#
PCI Express X16 Slot
PCI Express X1 Slot
Order2
Order3
INT C#
INT D#
INT D#
INT A#
Order4
