Computer system

Abstract

The invention discloses a computer system which comprises a system management bus controller, a logic circuit and a complex programmable logic device, wherein the system management bus controller generates a first signal and a second signal; the first signal is used for indicating a power-on self test detection state of the computer system; the second signal is used for indicating a default state; the logic circuit is coupled to the system management bus controller, receives the first signal and the second signal and generates a logic circuit; and the complex programmable logic device is coupled to the logic circuit, receives the logic signal and generates a restart signal of the computer system according to the logic signal. According to the computer system, the problem of mistakes made in signal judgment and accessing of the computer system due to no use of a baseboard management controller in the computer system in the prior art is solved.

Description

technical field [0001] The present invention relates to the technical field of computers, in particular to a computer system. Background technique [0002] Generally speaking, a baseboard management controller (BMC) is usually configured in a computer system to manage the working status of the entire computer system, such as temperature, voltage, fan, and power supply. The baseboard management controller will provide functions such as self-monitoring, event recording and error recovery, and is a very important management component in the computer system. [0003] Based on the design concept of cost control and performance optimization, the newly developed computer system gradually no longer uses the baseboard management controller to control the communication of signals, but uses the platform controller hub (Platform Controller Hub, PCH) instead. However, since the use of the baseboard management controller is omitted, and the transmission interface or transmission path of ...
