AI Technical Summary

Problems solved by technology

It should be noted that, as shown in FIG. 3A , when the AGP display card 30 is inserted on a motherboard 10 through an AGP slot 14 , the input and output ends of the AGP display card 30 must correspond to the computer case 40 correctly. The opening of the back panel (back panel), otherwise the AGP display card 30 will not be able to be locked on the computer case 40, and the use of the input and output terminals of the display card 30 will also be hindered
[0014] Therefore, referring to FIG. 3B, if an adapter card 20 is added to the PCI slot 12, the position of the AGP display card 30 will be moved upwards, and the lock hole 32 of the display card 30 cannot be aligned with the computer case 40. The lock hole 42 on the top will cause difficulties in using, assembling and fixing the AGP display card 30

Embodiment Construction

[0034] Table 1 lists the differences between the AGP interface and the PCI interface.

[0035] Table 2 categorizes the AGP feature pins.

[0036] Table 3 shows the vacant pins of each AGP slot by category.

[0037] Please refer to Figure 4A , which shows a preferred embodiment of the present invention to convert the AGP interface into the motherboard architecture of the PCI interface. As shown in the figure, the motherboard structure includes a north bridge chip 100 , a south bridge chip 200 , an AGP slot 230 and at least one PCI slot 220 . The north bridge chip 100 is connected to the CPU 120 and the main memory 140 , and is connected to the south bridge chip 200 through a PCI bus (PCI bus). The south bridge chip 200 has a PCI controller 210 inside, and the PCI controller 210 is connected to the AGP slot 230 and the PCI slot 220 simultaneously through a bus.

[0038] exist Figure 4A Among them, the PCI controller 210 is located within the south bridge chip 200 . Howev...
