Method for checking quality of server main board memory signals through BMC

Abstract

The invention discloses a method for checking the quality of server main board memory signals through a BMC, and relates to the field of main board management. The method includes the steps that a BIOS is modified, memory signal quality data tested by an MRC code in the BIOS starting process is stored into an FRU EEPROM of a main board, after the BIOS is started, the BMC is informed of reading the memory signal quality data tested by the MRC code in the EEPROM and storing the memory signal quality data, and then the data is displayed visually through a BMC management interface. The test data of multiple adjacent memory signals can be checked in the BMC management interface so as to help people to know about the current memory signal condition, problems related to a memory are located, and development personnel are helped to check the quality of the memory signals and related problems caused by locating the memory.

Description

technical field [0001] The invention discloses a method for checking the signal quality of a mainboard of a server through a BMC, and relates to the field of mainboard management. Background technique [0002] The X86 server is a processor that adopts the cisc (Complex Instruction Set Computer, complex instruction architecture computer) architecture. In the CISC processor, the instructions of the program are serially executed in sequence, and the operations in each instruction are also executed in sequence. executed serially. In X86 server products, the quality of the memory signal is related to the stability of the entire product. The quality of the memory signal is not only related to the PCB layout, but also has a certain relationship with the memory module itself and its particles. In order to visually view the memory signal, The MRC code under the BIOS usually tests the quality of the memory signal during the BIOS startup stage, and the test data can be printed out thr...

In X86 server products, the quality of the memory signal is related to the stability of the entire product. The quality of the memory signal is not only related to the PCB layout, but also has a certain relationship with the memory module itself and its particles. In order to visually view the memory signal, The MRC code under the BIOS usually tests the quality of the memory signal during the BIOS startup stage, and the test data can be printed out through the serial port. Although this method can be used in the debugging stage, the serial port printing is usually shielded in order not to affect the customer's use of the serial port. In this way, the memory test data thrown by the BIOS cannot be checked. The present invention provides a method for checking the quality of the memory signal of the mainboard of the server through the BMC. By modifying the BIOS program, it is possible to check the adjacent multiple memory signals in the BMC management interface. Test data to help us understand the current memory signal situation, and locate memory-related problems, and help developers check the quality of memory signals and locate related problems caused by memory
