Abstract

본 발명은 램(RAM)이 포함된 시스템에서 램을 세부적 모듈로 테스트하여 각 부분에서 나타나는 에러를 쉽게 디버깅할 수 있도록 한 시스템의 램 테스트 방법에 관한 것으로, 종래에는 SHA(SCSI Host Adapter) 보드의 펌웨어상에서 자체 프로그램은 있으나 디버깅할 수 있는 부분이 없었다.The present invention relates to a RAM test method of a system in which a RAM is tested as a detailed module in a system including RAM, so that errors occurring in each part can be easily debugged. The firmware has its own program but no debuggable part.

이와같은 종래의 결합을 감안하여 본 발명은 SHA보드의 디버깅진용 진단 프로그램을 만들어 램 테스트시에 세부적 모듈로 구분하여 테스트하므로써 램의 에러부분을 쉽게 찾을 수 있도록 함과 아울러 램의 신뢰성이 요구되는 부분에 적합하도록 한 효과가 있다.In view of such a conventional combination, the present invention makes it easy to find the error part of RAM by making a diagnostic program for the debug board of SHA board and classifying it into detailed modules during RAM test, and also requires the reliability of RAM. It is effective to make it suitable for.

Description

시스템의 램(RAM) 테스트 방법How to test your system's RAM

본 내용은 요부공개 건이므로 전문내용을 수록하지 않았음As this is a public information case, the full text was not included.

Claims (1)

보드에 파워 온시에 표시부(7)에 "램 테스트 메뉴"를 표시하는 단계와, 상기 램 테스트 메뉴에서 테스트선택 요구에 따라 "1"선택시 중앙처리장치(1)에서 램(3)에 데이타를 일정횟수만큼 반복 라이트하는 단계와, "2"선택시 중앙처리장치(1)에서 램(3)의 데이타를 일정한 횟수만큼 반복 리드하는 단계와, "3"선택시 4바이트를 램(3)에 라이트 및 리드하는 단계와, "4" 선택시 32비트중 1비트를 세트하여 램(3)에 라이트 및 리드하는 단계와, "5"선택시 램(3)에 일정한 패턴으로 라이트한 후 리드하는 단계와, "6"선택시 램(3)으로 부터 리드한 후 강제 패리티를 발생하여 에러를 처리하는 단계로 진행함을 특징으로 하는 시스템의 램 테스트 방법.Displaying a "RAM test menu" on the display unit 7 when the board is powered on; and selecting "1" in response to a test selection request from the RAM test menu. Repeatedly writing a predetermined number of times; repeatedly reading data from the RAM 3 by the predetermined number of times from the CPU 1 when selecting " 2 ", and selecting 4 bytes into the RAM 3 when selecting " 3 ". Writing and reading, and setting and writing to the RAM 3 by setting one bit of 32 bits when selecting "4", and writing after reading in a predetermined pattern to the RAM 3 when selecting "5" And a step of generating a forced parity and processing an error after reading from the RAM (3) when " 6 " is selected. ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
