Method for detecting integrity of PCIE (peripheral component interface express) equipment in system start-up process

The invention provides a method for detecting integrity of PCIE (peripheral component interface express) equipment in a system start-up process. The method comprises a PCIE equipment detection module, a test result display module and a data comparison module, and comprises the following concrete realization process: test results are compared and displayed in a PCIE equipment detection process; if the test results are completely matched, the system continuously runs, and the test result display module automatically restarts to start a next test after the data results are displayed by the test result display module; and if the test results are not matched, the system stays at the current environment, the data results are displayed by the test result display module. Compared with the prior art, according to the method for detecting the integrity of the PCIE equipment in the system start-up process, high reliability between the PCIE equipment and a mainboard is ensured, and indexes of the system in a compatibility aspect are increased, thereby the stability of the system is promoted.
