CONTROL CIRCUIT FOR MANAGEMENT ENGINE INTERFACE |
摘要 |
A control circuit includes a platform controller hub (PCH), a basic input/output system (BIOS), an electronic switch, and first and second resistors. A management engine interface is loaded in the PCH. The BIOS is connected to the PCH to control the signals output from a general input/output (GPIO) pin of the PCH. A power supply is connected to a serial pin of the PCH through the electronic switch. The GPIO pin of the PCH controls on or off of the electronic switch. |
