Computer mainboard PCIe slot function test method based on UEFI

Abstract

The invention provides a computer mainboard PCIe slot function test method based on a UEFI, and relates to the field of large-scale factory tests on computer mainboard PCIe slots. The computer mainboard PCIe slot function test method comprises the following steps: on the basis of a build-in uefi shell, firstly, confirming that a first start item of a machine is boot from build-in shell; according to a mainboard specification, inserting matched PCIe cards into corresponding PCIe slots in a mainboard; writing a test PCIe configuration file, and listing information of each slot; powering on the machine from uefi shell to enter a test U-disc automatically and operate a test program, thereby acquiring information of all PCIe cards in the PCIe slots; comparing grasped data with data in PCIe configuration files PCIE.INI, wherein the test is qualified if the files are completely identical, or else the test is unqualified. By adopting the computer mainboard PCIe slot function test method, no operating system needs to be started for test, so that the test time can be shortened, and the test efficiency can be improved.

Description

technical field [0001] The invention relates to the field of large-scale testing of PCIe slot factories of computer motherboards, in particular to a UEFI-based method for testing the functions of PCIe slots of computer motherboards. Background technique [0002] In the current production of PCIe slots on computer motherboards, functional testing is mostly required. [0003] In current computer products, the motherboard generally includes 2 to 8 PCIe interface slots. It is necessary to test whether the functions of these slots are normal during the production test of the motherboard to ensure that the motherboard is a good product. In the large-scale functional testing of the current computer motherboard PCIe slot factory, most of them are tested under operating systems such as DOS, Windows and Linux. If the test is done under DOS, the DOS environment needs to be a DOS boot disk with few drivers, and UEFI BIOS gradually does not support DOS. For example, the test under the...

AI Technical Summary

Problems solved by technology

If testing under the operating system, it needs to start the system, which takes a long time and depends on the system, such as installing drivers and corresponding tools, etc., and the daily maintenance is difficult, which is not conducive to large-scale production testing in factories

In the case of many tests, the machine frequently starts the operating system and restarts, resulting in a great waste of test time and manpower, and increases the test cost
