[Xinfanqie] tips: correctly enable the BIOS video card to prevent computer black screen troubles

I purchased an amd770 motherboard for my old computer, but I encountered a black screen when I started the computer. According to the merchant, this is a new motherboard. It should not be a quality problem, but may be caused by improper BIOS settings. The system home editor tried to find the problem multiple times in the BIOS of the motherboard.

Open Bois and enter the chipset-Northbridge-configuration-PCI Express configuration interface, which includes the following: "primary Video Controller ", it has four options, including PCIe GFX0-GFX2-GPP-PCI, pcle GFX2-GFX0-GPP-PCI, PCIe GPP-GFX0-GFX2-PCI, and PCI-PCIEGFX0-GFX2-GPP. By default, it is the pcle GFX0-GFX2-GPP-PCI ".

On the surface, "primary Video Controller" can be understood as the master video card controller, but it actually means the Starting sequence of the video card. At present, many AMD chipset boards support integrated graphics card or video card exchange functions. In this case, you need to adjust the priority of the video card to achieve different purposes, as a result, black screen problems occur due to the video card startup sequence.

The following example shows how to download the motherboard from the XP system. However, the naming of the options varies depending on the motherboard BIOS. You can look for similar identification and settings. In the options, gfx0, gfx1, gfx2 refers to the PCI-E x16 interface (slot), followed by 0, 1, 2 is the interface order; GPP is the PCI-E X1 graphics interface; igfx or GFX is the VGA interface of the integrated video card on the motherboard, while PCI is the PCI interface of the old video card.

The motherboard is equipped with two PCI-E X1, one PCI-E x16 and three PCI slots, and the interface serial number of this PCI-E x16 slot is actually gfx2, and gfx0 does not exist. If you use the BIOS's default pcle GFX0-GF X2-GPP-PCI settings, the computer system will first start a non-existent graphics interface, so it will be black. Change this option to "PCIEGFX2-GFXO-GPP-PCI", let the gfx2 interface of the independent graphics card first start, you can solve the problem of black screen.
