Abstract
A circuit allowing self-recovery of an operating system (OS) includes a PCH chip, a switch chip, a first ROM, a second ROM, a connector, and a storage unit. The switch chip, the second ROM, and the connector are coupled to the PCH chip. The first ROM is coupled to the PCH chip through the switch chip. The second ROM controls the PCH chip to output a signal according to the state of the operating system. The first ROM stores a backup the operating system. The switch chip receives control signal from the PCH chip, and controls whether the first ROM communicates with the PCH chip, to allow recovery of the entire or part of the OS in the event that repair is required.
