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.

Claims

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.
