Description

Checking method for installation correctness of computer PCI/PCI Express equipment

technical field

The invention relates to a method for detecting the correctness of computer hardware installation, in particular to a method for detecting the correctness of PCI (Peripheral Component Interconnect)/PCI Express device installation.

Background technique

After installing PCI/PCI Express devices such as sound cards, graphics cards, network cards, and TV adjuster cards in the computer system, the correctness of the installation of these PCI/PCI Express devices must be checked to ensure that these PCI/PCI Express devices can work normally in the computer system. Work. The correctness detection method of traditional PCI/PCI Express device installation includes two kinds of methods of manual test and automatic test. The method of manual testing is to judge the correctness of the device installation by comparing the bus number, device number and function number of the PCI/PCI Express device with the set values in the configuration file of the computer system. , the device number and function number depend on the specific hardware configuration of the computer, so this method requires the user to first assemble a computer according to the BOM (Bill of Material, equipment installation table), and then run configuration file generation on this computer program to generate configuration documents, if there are alternative materials for some components of the computer (such as graphics card, memory and other components can choose other models), it is necessary to use the alternative materials to assemble another computer, and then repeat the above process to generate a new Configuration documents, if there are alternative materials for several components, the operator will have to generate multiple sets of configuration documents according to the above process for all possible different configurations. This method requires many links of manual intervention, is inefficient and is not suitable for the situation where there are many alternative materials.

The automatic test method is to obtain the slot (slot) information of the computer by reading the routing table (Routing Table) information in the BIOS (Basic Input/Output system, basic input/output system), thereby judging that the slot on the specified slot is Whether the installed PCI device is correct, but this method requires the BIOS to have a complete routing table, and in actual work, there are many computer slot information such as AGP (Accelerated Graphics Port, accelerated graphics interface) slot and It is not recorded in the routing table, so it is impossible to determine whether the correct PCI/PCI Express device is installed on the AGP slot or other slots that are not recorded in the routing table. In addition, some advanced PCI/PCI Express card devices can also add sub-cards. Since the sub-cards are not connected to the motherboard through the slot, but are attached to the mother card, the self-test function of the BIOS cannot be completed at this time. detection tasks.

Detailed ways

Please refer to Fig. 1, the detection system of computer PCI/PCI Express equipment installation correctness of the preferred embodiment of the present invention comprises a SQL (Structured Query Language, Structured Query Language) database 10, a configuration file generator 20 and a UUT (Unit Under Test, in the test device) station 30. Described database 10 is used for preserving various motherboard information (comprising PCI onboard equipment information and slot information), PCI/PCI Express equipment (network card, graphics card etc.) information and BOM table (Bill ofMaterial, equipment installation table). Described configuration file generator 20 is connected with described database 10 and described UUT work station 30 by network, in order to generate PCI/PCI Express configuration file according to BOM table, motherboard information and PCI/PCI Express equipment information preserved in database 10 And transmit to the UUT workstation 30. Described UUT workstation 30 comprises at least one computer to be tested, and various PCI/PCI Express devices to be detected are installed on the computer to be tested, and described computer to be tested also includes a detection module. After the detection module has detected all PCI/PCI Express devices, the UUT workstation 30 automatically generates a PCI device test report. PCI/PCIExpress equipment information such as described motherboard information and network card, graphics card are stored in the described database 10 with the form of XML (Extensible Markup Language, Extensible Markup Language), and described BOM table is with Excel (form processing software produced by Microsoft Corporation) ) form records the hardware combinations of the computers under test with various hardware configurations of the UUT workstation 30.

Please refer to Fig. 2, utilize the detection system of described computer PCI/PCI Express device to install correctness to detect the operating steps of PCI/PCI Express device install correctness as follows:

(1) various motherboard information and PCI/PCI Express equipment information are saved in the described database 10. Mainboard information includes onboard device information and slot information. Onboard device information includes onboard device path, function number, classification code, manufacturer mark, device mark, subsystem device mark, subsystem manufacturer mark, etc. The path of the device is composed of the bus number and the device number; the slot information includes the path of the slot, the bus number, the device number, the function number and other information. Described PCI/PCI Express device information comprises the relative path of PCI/PCI Express device, bus number, device number, function number etc. Because except root bus (bus 0), the bus numbers of other buses may vary with the configuration of PCI/PCIExpress equipment, thereby utilize relative path to mark the installation position of PCI/PCI Express equipment and save in described database 10 , the relative path is made up of the equipment passing through from a certain bridge to the specified equipment node, and the path of the bridge is marked with a device number and a function number (for example, the root bus (bus 0) attached on the root bus (bus 0) in Figure 4 Device 1 is a bridge, and its path Path=D01F00 refers to No. 0 function of No. 01 device).

(2) Save the BOM table in the database.
