DE102004048477A1 - Supply method of accelerated graphics port card on peripheral component interconnect bus slot of motherboard, involves scanning status of peripheral component interconnect bus slot, and out-connecting accelerated graphics port card - Google Patents

Abstract

A detecting signal provided by basic input/output system (BIOS) is transmitted to a motherboard. The status of peripheral component interconnect (PCI) bus slot on the motherboard is scanned. The accelerated graphics port (AGP) card is then out-connected to a PCI bus slot for displaying.

Description

The The invention relates to a method for providing AGP (Accelerated Graphics Port) card in a PCI (Peripheral Component Interconnect) bus slot and in particular a layout of a PCI bus that corresponds to the layout of an AGP bus is adjusted.

buses in industrial computers according to the state The technology will be in ISA (Industry Standard Architecture), VISA (Virtual Instruments Software Architecture), PCI, AGP and so on classified. Furthermore, a plurality of slots are on set up a motherboard and interface cards in appropriate slots plugged in. The interface cards are coupling devices between the peripherals and the peripherals are controlled by the motherboard by means of the interface cards. Further, earlier ISA slots to VISA slots developed and the VISA slots were then developed to PCI slots. Now the PCI slots continue to AGP slots developed.

nowadays technologies are greatly improved but still some ISA slots and PCI slots set up together on old motherboards. That is why it is when in all ISA slots ISA interface cards are plugged in, impossible another ISA interface card to plug into any slot on the motherboard and the same is the case with the PCI slots. An interface card with two types of interfaces can in both a PCI slot and an ISA slot on the Motherboard be plugged. The slot interfaces are not on special ones Limited tickets and therefore the costs are reduced.

In 1 are a plurality of component parts 11 on the interface card 10 set up; furthermore, they are a first connection interface 12 and a second connection interface 13 on different sides of the interface card 10 set up and compatible with PCI (Peripheral Controller Interface) and ISA (Industry Standard Architecture). In addition, the first connection interface 12 and the second connection interface 13 with the component parts 11 coupled by means of different wires; Further, a connection part 14 on a border section of the interface card 10 set up so that it connects to the first connection 12 and the second connection interface 13 can be coupled. Further, a solid plate 15 at the edge portion of the interface card 10 attached and provides an opening (not shown), in which can be inserted and the connecting part 14 covered.

however Can not get an AGP interface card into a motherboard only plugged in with PCI slots because there is no AGP slot on the motherboard. Therefore, a new motherboard with AGP slots is required.

The The invention provides a method for providing an AGP card in a PCI bus slot and avoids the disadvantages of prior art motherboards.

According to the invention is a Method provided with the following steps: Submitting a detection signal to a motherboard, detecting the status a plurality of PCI bus slots the motherboard and using an external AGP card to display.

To the better understanding The invention is illustrated in the following detailed description embodiments and examples of the invention, the detailed description is intended only to illustrate the invention.

1 shows a schematic diagram of a prior art interface card with PCI interface and ISA interface;

2 FIG. 12 shows a flowchart of a method of providing an AGP card in a PCI bus slot.

in the Generally, display functions will be in three different ways provided. First, the AGP display functions of chips provided on the motherboard with built-in display functions and built-in display functions are usually portable Computer for official Used purposes. Second, an AGP card is for playing computer games with good and fluid Display required, with the AGP card plugged into an AGP slot is. Furthermore, built-in display functions of the chips are not sufficient for playing computer games. Third, the invention ceases Method for setting up an AGP card in a PCI bus slot ready. That's why User select display functions, those from a paired external AGP card or built-in Display functions if AGP is not provided.

A motherboard with lower price points only PCI slots and chips with built-in display functions on. Therefore, an AGP card can be plugged into a PCI slot by mapping PCI signals as AGP signals. The defined bandwidth of PCI signals is less than that of the AGP signals, but the pins for receiving AGP signals and PCI signals are the same. Further, AGP performs better than PCI and the pinouts of an AGP bus slot and a PCI bus slot are not the same.

2 FIG. 12 shows a flowchart for providing an AGP card in a PCI bus slot which includes the steps of: transmitting a detection signal to a motherboard (S100); Detecting the status of a plurality of PCI bus slots on the motherboard (S102); Deciding whether an external AGP card is coupled to any PCI bus (S104) and adjusting a layout of the PCI bus to a layout of an AGP bus; if the result generated in (S104) is Yes, then use an external AGP card for display (S106); otherwise Use a built-in display chip to display (S108).

Motherboards according to the state The technology uses different interface cards for different Features, but the invention adapts a PCI slot layout Layout of an AGP slot. Therefore, signals are from the PCI bus converted into signals of the AGP bus and then the AGP card in plug in the PCI slot on the motherboard.

clear are the number of pins of a PCI slot and the number of pins Pins of an AGP slot, but will be different used. Therefore, in one embodiment, a corresponding one of Software generates a mapping table with which the signals, the correspond to the pins of a paired AGP card, to the associated pins of the PCI bus (and vice versa).

clear Thus, the PCI bus signals are interpreted by the AGP card as AGP bus signals.

On this way a new and not obvious PCI bus has been described, which solves the above problem in the prior art. Further recognizes the skilled person that the above description is illustrative only for specific embodiments and examples of the invention. The invention should therefore be various Modifications and variations of the structure described herein and Functioning of the invention cover, if they are within the range of the invention as defined by the following appended claims becomes.
