  • ERASING CONTROL CIRCUIT AND METHOD FOR ERASING ENVIRONMENT CONFIGURATION MEMORY IN A COMPUTER SYSTEM
    Publication number: 20090225615
    Abstract: A computer system includes a power switch, a reset switch, environment configuration memory, and an erasing control circuit. The power switch is for starting the computer system as triggered. The reset switch is for resetting the computer system as triggered. The environment configuration memory is for storing an operational environment setting of the computer system. The environment configuration memory has a power supply pin. The erasing control circuit is connected to the power switch, the reset switch and the power supply pin. The erasing control circuit connects the power supply pin to a ground voltage as the power switch and the reset switch are triggered simultaneously.
