Patent ID: 8074114

Claim:
A motherboard error detection system, comprising: a motherboard having a boot management chip, wherein, when the motherboard undergoes a standby status, a boot status, a BIOS (Basic Input/Output System) check status and a device-driven status, the boot management chip manages power-on timings of a plurality of voltage sources in accordance with a power sequence, and periodically collects a plurality of sets of system status information of the motherboard, and checks whether the sets of system status information and the power-on timings of the voltage sources have errors, wherein the boot management chip comprises: a power pin used to supply power; an analyzer enable pin; and a MD mode pin using a change of high-level status or low-level status to provide a message regarding whether an error message is available; and a pluggable error detection board, comprising: an interpreting unit; a connector pluggably disposed on the motherboard, wherein, when the connector is plugged into the motherboard, an electrical connection is established between the interpreting unit and the boot management chip, and the connector being connected to the power pin for receiving supplied power, and being connected to the analyzer enable pin for detected whether the pluggable error detection board is electrically connected to the motherboard, and being connected to the MD mode pin for receiving the message; and a message-reading interface electrically connected to the interpreting unit; wherein, when finding errors, the boot management chip notifies the pluggable error detection board to read the error message from the boot management chip, and the interpreting unit converts the error message to human-readable information, and the human-readable information is outputted through the message-reading interface.
