PCI Interrupt Request Routing

IRQ, or interrupt request lines, are hardware lines over which devices can send interrupt requests to the processor. The PCI IRQ pins are typically connected to the PCI bus pins as followed:

	Order1	Order2	Order3	Order4
PCI Slot1	INT A#	INT B#	INT C#	INT D#
PCI Slot2	INT B#	INT C#	INT D#	INT A#

Video/ Graphics Cards

If available, this mainboard takes advantage of the CPU’s integrate graphics processor, but discrete video cards can be installed by way of the mainboard’s expansion slots. Adding on one or more discrete video cards will significantly boost the system’s graph- ics performance. For best compatibility, MSI graphics cards are recommended.

Single Video Card Installation

1.Determine what type of expansion slot(s) the video card will use. Locate the expan- sion slot(s) on the mainboard. Remove any protective expansion slot covers from the computer case.

2.Line up the video card on top of the expansion slot(s) with the display ports facing out of the computer case. For a single video card installation, using the PCI_E2 slot is recommended.

3.Push the video card into its expansion slot(s). Depending on the expansion slot(s) used, there should be clip(s) on the expansion slot(s) that will lock in place.

4.If needed, screw the edge of the graphics card to the computer case. Some video cards might require a power cable directly from the power supply.

5.Please consult your video card’s manual for further instructions regarding driver installation or other special settings.
