ABSTRACT:
A computer system utilizing the Advance Configuration and Power Interface (ACPI) Standard to notify an ACPI compliant operating system of a detected correctable error. The computer system includes and error check circuit that detects correctable and non correctable errors in computer information flowing between the processor and a RAM. The error correction circuit provides a CE signal in response to detecting a correctable error. The computer system includes a register block circuit, that when enabled, generates an SCI to the processor in response to receiving the SCI. The processor accesses a status register of the SCI to determine that the error signal was sent. An ACPI driver of the operating system interprets ACPI control methods to direct the processor to perform the functions of the control method to obtain an address and syndrome of the information unit having the detected correctable error.
