Correctly enable the boot sequence of the BIOS video card to effectively prevent computer black screen trouble

For their old computer purchased a AMD770 motherboard, replaced on the boot that appears black screen phenomenon. According to the merchant said this is a new motherboard, should not be a quality problem, perhaps due to improper BIOS settings. The system bar to try to explore in the bios of the motherboard many times, finally found the problem.

Open the Bois and enter the CHIPSET-NORTHBRIDGE-CONFIGURATION-PCI Express Configuration interface, which has one such item: "Primary video Controller", it has PCIe 4 options for Gfx0-gfx2-gpp-pci, Pcle Gfx2-gfx0-gpp-pci, PCIE Gpp-gfx0-gfx2-pci, and PCI-PCIEGFX0-GFX2-GPP. In the default state, Pcle Gfx0-gfx2-gpp-pci.

"Primary video Controller" On the surface can be understood as the main graphics controller, but in fact the graphics card boot sequence meaning. At present, many AMD chipset motherboards support the integration of video card or video card fire and other functions, then need to adjust the priority of the video card to achieve a different purpose, which is due to the video card starting sequence led to black screen problem now.

The system bar to the above motherboard for example, but the name of the option will be different from the motherboard BIOS, you can look for similar to identify and set. In the option, GFX0, GFX1, GFX2 refers to the Pci-e x16 Interface (slot), followed by 0, 1, 2 is actually the interface order; GPP refers to the PCI-E X1 graphics interface, IGFX or GFX is the VGA interface of the integrated video card on the motherboard, and PCI is the PCI interface of the old video card.

The motherboard is equipped with two pci-e x1,1 pci-e x16 and 3 PCI slots, and the interface serial number for this pci-e x16 slot is actually gfx2,gfx0 does not exist. If you use the BIOS default "pcle GFX0-GF x2-gpp-pci" setting, you will first start the nonexistent video card interface, so it will be black screen. To change this option to "Pciegfx2-gfxo-gpp-pci", so that the insertion of independent graphics GFX2 interface priority to start, you can solve the problem of black screen.
