Abstract
The present invention discloses a method of providing AGP card set on PCI bus slot. The method includes: transmitting one detection signal to one mainboard; scanning the state of the bus slots in the mainboard; and using one externally connected AGP card for display. Adopting the method of the present invention makes it possible to use display chip, which does not back up AGP function originally, in AGP interface card.
Description
Technical field
A kind of method that provides the AGP card to be provided with on the pci bus slot is provided, relates in particular to and a kind of existing arbitrary pci bus is planned to a bus that meets the AGP specification again.
Background technology
The bus architecture of existing industrial computer is divided into ISA, VISA, PCI and AGP etc., all be provided with several inserting grooves on the motherboard of general main frame, the interface matched card with it of need planting on this inserting groove, this interface card is mainly the coupling arrangement between interfacing equipment and motherboard, make motherboard can pass through interface card control interface equipment, this inserting groove from early stage ISA inserting groove progress to the VISA inserting groove, again by the VISA inserting groove further to the PCI inserting groove up to popular now AGP inserting groove.
In so progressive epoch of science and technology now, some occasion still only needs to use more old motherboard, and this motherboard may run into the inserting groove that some partly is the ISA interface, and some part is the inserting groove of pci interface.When on running into this motherboard, all sticking with interface card, if will plug another PCI again or the ISA interface card is very difficult, therefore in order to solve this problem, at TaiWan, China patent announcement number No. 488533 " with the interface card of PCI and ISA interface ", it discloses a kind of interface card with PCI and ISA interface, when making interface card be connected with the motherboard of main frame, the difference of inserting groove on the plate at random, the connecting interface that this interface card cooperates with this inserting groove is planted wherein, no longer be subject to the specification of inserting groove, more do not need difference, use the interface card that is mated, and then reach cost-effective purpose with the inserting groove interface.
Its structure as shown in Figure 1, a plurality of spare parts 11 are installed on this interface card 10, in addition, this interface card 10 is respectively equipped with on different edges and perimeter component commissure interface (PCI), reach first of Industry Standard Architecture framework (ISA) compatibility, two connecting interfaces 12,13, this is first years old, two connecting interfaces 12,13 and be connected with identical spare part 11 by different circuits, and, this interface card 10 is provided with and first, two connecting interfaces 12,13 plug sockets that are connected 14, this plug socket 14 is installed in interface card 10 respectively wherein on one side the edge, in addition, this interface card 10 can sealedly have a fixed flat planar 15 that cooperates at the edge that is provided with plug socket 14, this fixed flat planar 15 is provided with the perforate (not shown) that wears for plug socket 14.
Yet, another kind of situation is to be the PCI inserting groove on the motherboard totally, and when the user has the add-on card of another AGP to want to use, can't on this motherboard, use, because on this motherboard, there is not the AGP inserting groove, therefore cause the user to buy new motherboard, cause user's inconvenience at ancillary cost.
Summary of the invention
Technical matters to be solved by this invention is to propose a kind of method that provides the AGP card to be provided with on the pci bus slot, to solve the problem that does not have the AGP inserting groove in the above-mentioned prior art on the motherboard.
A kind of method that provides the AGP card to be provided with on the pci bus slot is provided in the present invention, comprises and transmits a detection signal to a motherboard; Scan the state of a plurality of bus slots on this motherboard; And judge that whether external AGP card, the pci bus of this external AGP card are arranged is the layout circuit that the layout circuit of this pci bus is planned to again the AGP bus on arbitrary pci bus, if judged result is for being then to use an external AGP to stick into the function of row demonstration.
The method that provides the AGP card to be provided with on the pci bus slot of the present invention is provided, can will originally not support the display chip of the function of AGP can use the AGP interface card, utilize the present invention the circuit of a PCI slot to be planned to again the circuit of AGP slot, can make the conversion of signals of a pci bus become the signal of AGP bus, allow this motherboard can plug the display card of AGP.
Description of drawings
Fig. 1 is the interface card floor map with PCI and ISA interface of prior art; And
The method flow diagram that provides the AGP card to be provided with on the pci bus slot of the present invention is provided Fig. 2.

Embodiment
Below in conjunction with accompanying drawing the present invention is elaborated.
The display chip of general chip manufacturer manufacturing roughly is divided into three kinds, first kind is the chip of only supporting the AGP function, so when only making document and handle and can't insert AGP and do not need very good chip as mobile computer, so Presentation Function on the display card is added in the display chip, and this is the product of lowest price.The second, when we play computer game possibly, be to show fine and smooth action, so we buy in the slot that the add-on card of an AGP inserts AGP if use built-in display chip.The 3rd, be exactly that the designed method that the setting of AGP card is provided on the pci bus slot of the present invention is supported simultaneously, if just use the Presentation Function of built-in chip when the user does not have money to buy card, just use the Presentation Function of add-on card when adding card (AGP) and the function of built-in chip is turned off when the user buys.
The user has bought the motherboard of low price, and this motherboard has only the interface of PCI, just have only built-in display chip and do not have AGP, yet the user is if there is the AGP card, we all move the signal of PCI to above the signal of AGP now, because PCI is when definition, defined frequency range is very little, afterwards in definition AGP signal, the signal pin of AGP and the pin of PCI are the same, and the function of the function ratio PCI of AGP is better, and just many several pin are though the different function of PCI and AGP definition of pin position is identical.
As shown in Figure 2, the method flow diagram that Fig. 2 provides the AGP card to be provided with on the pci bus slot for the present invention, this method comprises the steps: to transmit a detection signal (step S100) to a motherboard, this detection signal is provided by a Basic Input or Output System (BIOS) (BIOS), scan the state (step S102) of a plurality of pci bus slots on this motherboard, whether judgement has external AGP card (step S104) on arbitrary pci bus, the pci bus of this external AGP card is the layout circuit that the layout circuit of this pci bus is planned to again the AGP bus, if judged result is for being, then use an external AGP to stick into the function (step S106) that row shows, otherwise, if judged result is for denying the function (step S108) of then using a built-in display chip to show.
Difference from prior art is, prior art is to use the mode of interface card to reach desired function, and problem to be solved by this invention to be display chip originally do not support the AGP function, utilize the present invention can use the AGP interface card, utilize the present invention the circuit of a PCI slot to be planned to again the circuit of AGP slot, make the conversion of signals of a pci bus become the signal of AGP bus, allow this motherboard can plug the display card of AGP.
Certainly; the present invention also can have other various embodiments; under the situation that does not deviate from spirit of the present invention and essence thereof; those of ordinary skill in the art work as can make various corresponding changes and distortion according to the present invention, but these corresponding changes and distortion all should belong to the protection domain of the appended claim of the present invention.
