Abstract

본 발명은 사용자로 하여금 다수의 기능 카드중 하나가 에러 신호를 송출하였는지를 확인할 수 있게 하는 컴퓨터 시스템을 제공한다. 에러 신호를 송출한 장치는 격리되고 에러 복구 기법(또는 재초기화)이 에러 상태를 갖는 장치상에만 구현된다. 컴퓨터 시스템은 다른 정보 버스와 I/O, 메모리 등과 같은 특정 기능을 수행하는 기능 카드를 수납하는 적어도 한 개의 커낵터 슬롯을 상호접속하는 브리지 칩과 함께, 부가적인 제어 논리회로를 포함한다. 에러 신호가 존재한다고 판단되면, 시스템 하드웨어는 에러 신호를 송출한 장치에 리셋 신호를 활성화시켜 유지한다. 또한, 브리지 칩내의 레지스터내 상태 비트가 세트된다. 이어서 에러 신호를 송출한 장치에 대응하는 장치 드라이버가 상태 비트를 판독하여 에러가 발생했음을 확인한 후 브리지를 리셋하고, 에러 상태를 갖는 장치만을 리셋하거나 초기화한다.
