Problems solved by technology
During the cycle test of the main board, if the main board is bad, it may crash during a certain boot. At this time, the POST indicator can indicate the POST code at the time of the crash, but the main board will display during the POST process. Several times of the same code, the tester cannot judge at which stage the motherboard crashes according to the currently indicated POST code, which makes it difficult to repair the motherboard

The invention discloses a mainboard power on self test (POST) code detecting system, which comprises a detected mainboard, a monitoring computer and a POST code detecting plate, wherein the detected mainboard is used for generating POST codes during power-on / power-off testing; the POST code detecting plate is connected between the monitoring computer and the detected mainboard, and is used for transmitting the POST codes generated by the detected mainboard to the monitoring computer; and the monitoring computer is used for storing the received POST codes one by one. The invention also discloses a mainboard POST code detecting method. By the mainboard POST code detecting system and the mainboard POST code detecting method, the POST codes generated by the detected mainboard are recorded so as to search the reasons of mainboard failure.
Description
technical field The present invention relates to a detection system and method, in particular to a motherboard power-on self-test code detection system and method. Background technique After the computer motherboard is produced, it is usually subjected to a power cycle test to verify its performance. During the power on / off test, the motherboard will generate a POST (Power On Self Test) code. POST is a routine program in which the motherboard's BIOS (Basic Input Output System, Basic Input Output System) performs a self-test on each module of the motherboard when the motherboard is powered on and started. POST information refers to various information obtained by the BIOS checking each module during the POST process, including: whether each module exists, whether the status of each module is normal, whether the initialization is completed normally, CPU type, CPU main frequency, memory type, memory capacity , hard disk capacity, BIOS version information, etc. During the cy...
