Method and system for diagnosing apparatus

Abstract

A method for diagnosing an apparatus in a computer system, which includes: determining to enter a diagnostic mode after the computer system is started; initializing a cache in the computer system; after initializing the cache, performing a diagnosis of the apparatus by executing a diagnostic program; and after the diagnosis of the apparatus is completed, executing a Basic Input Output System (BIOS) or Extensible Firmware Interface (EFI) program and loading an operating system.

What is claimed is: 
     
         1 . A method for diagnosing an apparatus in a computer system, comprising:
 determining to enter a diagnostic mode after the computer system is started;   initializing a cache in the computer system;   performing a diagnosis of the apparatus by executing a diagnostic program; and   executing a Basic Input Output System (BIOS) or Extensible Firmware Interface (EFI) program and loading an operating system.   
     
     
         2 . The method according to  claim 1 , wherein the step of determining comprises:
 detecting a trigger of a General Purpose Input/Output (GPIO) pin level.   
     
     
         3 . The method according to  claim 1 , wherein
 the diagnostic program is independent of the BIOS or EFI program.   
     
     
         4 . The method according to  claim 1 , further comprising:
 loading the diagnostic program into the cache for execution.   
     
     
         5 . The method according to  claim 1 , further comprising:
 initializing a serial port in the computer system before performing the diagnosis of the apparatus; and   outputting diagnostic results of the apparatus through the serial port.   
     
     
         6 . A non-transitory storage medium configured to store units comprising:
 a determining unit configured to determine to enter a diagnostic mode after a computer system is started;   an initializing unit configured to initialize a cache in the computer system;   a diagnosing unit configured to diagnose an apparatus in the computer system by executing a diagnostic program; and   a normal startup unit configured to execute a Basic Input Output System (BIOS) or Extensible Firmware Interface (EFI) program, and load an operating system.   
     
     
         7 . The non-transitory storage medium according to  claim 6 , wherein the determining unit is configured to detect a trigger of a General Purpose Input/Output (GPIO) pin level. 
     
     
         8 . The non-transitory storage medium according to  claim 6 , wherein the diagnostic program is independent of the BIOS or EFI program. 
     
     
         9 . The non-transitory storage medium according to  claim 6 , further comprising:
 a loading unit configured to load the diagnostic program into the cache for execution.   
     
     
         10 . The non-transitory storage medium according to  claim 6 , wherein the initializing unit is further configured to initialize a serial port in the computer system before the diagnosis of the apparatus is performed, further comprising:
 an outputting unit configured to output diagnostic results through the serial port after the diagnosis.
