Method, device and system for testing BIOS memory fault detection capability

Abstract

The invention discloses a method, a device and a system for testing BIOS memory fault detection capability, which simulate a memory fault in a state that a memory bank is accessed into a memory protection slot of a server to be tested and a memory data pin and a grounding pin of the memory protection slot are connected so as to judge whether a BIOS recognizes the memory fault or not, therefore, whether the memory fault detection capability of the BIOS is qualified or not can be judged. Memory faults are simulated through the memory data pin and the grounding pin which are connected with the memory protection groove, bit faults in the power-on self-test stage of the server can be simulated, correctable errors generated after an operating system runs can be simulated, and compared with the mode that the memory faults are injected through software in the prior art, not only is the cost of a software fault injection tool saved, but also the operation of simulating the memory fault is greatly simplified, and the operation threshold of BIOS memory fault detection capability testing is reduced, so that the labor cost is further reduced.

Description

technical field [0001] The invention relates to the technical field of servers, in particular to a method, device and system for testing BIOS memory fault detection capabilities. Background technique [0002] BIOS (Basic Input Output System, Basic Input Output System) is a set of programs solidified on a ROM chip on the motherboard of the computer. Program, its main function is to provide the computer with the lowest and most direct hardware setting and control. Memory fault monitoring is one of the BIOS factory test items. In the prior art, the memory fault of the server is simulated by injecting faults through software, and it is tested whether the BIOS can detect the set memory fault, so as to determine whether the ability of the BIOS to detect the memory fault is qualified. [0003] Injecting memory faults through software requires the use of MEI tools or ITP tools for injection. The hardware of these two tools is expensive, and a test environment (including hardware c...

AI Technical Summary

Problems solved by technology

[0003] To inject memory faults through software, you need to use MEI tools or ITP tools for injection, and the hardware of these two tools is expensive, and you need to build a test environment (including hardware Connection and software testing environment), the operation process is complex and cumbersome, and it is difficult to realize the error injection in the power-on self-test (Power On Self Test, POST) stage, resulting in incomplete testing of BIOS memory fault detection capabilities
