Personal computer diagnostic test before executing operating system

Abstract

A personal computer component diagnostic method is executed to recognize the status or potential problems of a computer before executing an operating system. The personal computer component diagnostic method comprising: calling a BIOS program; executing a component basic diagnostic program; and executing a component functional test after executing a predetermined step. The component functional test includes a CPU MSR/MTRR test, a hard disk S.M.A.R.T. test, a boot path test and a PCI device scanning test.

1 . A personal computer component diagnostic method before an operating system is executed, the personal computer component diagnostic method comprising:
 calling a BIOS program;   executing a component basic diagnostic program for detecting the personal computer;
 when receiving a trigger event, selecting and executing at least one specific component functional test for detecting a configuration of the specific computer component; and 
 displaying the configuration of the specific computer component. 
   
     
     
         2 . The personal computer component diagnostic method of  claim 1 , the functional test can be terminated by a interrupt signal. 
     
     
         3 . The personal computer component diagnostic method of  claim 1 , when the bios receiving a trigger event, the component functional test for recognize the computer component status and potential problems. 
     
     
         4 . The personal computer component diagnostic method of  claim 1 , when bios receiving a trigger event, duplicating and executing at least one specific component functional test for specific of the computer component in a memory. 
     
     
         5 . A personal computer component diagnostic module for executing a diagnostic method before an operating system is executed, the personal computer component module comprising:
 a random access memory;   a BIOS module;   a CPU for calling and executing the BIOS module in the random access memory; and   a component functional test module for executing a component functional test program;   when bios receiving a trigger event, duplicating and executing at least one specific component functional test program for detecting a configuration of the specific computer component in a memory.   
     
     
         6 . The personal computer component diagnostic module of  claim 5 , component functional test program for detecting configuration of a hard disk, or configuration of a boot path or configuration of a PCI device, or configuration of a CPU MSR/MTRR. 
     
     
         7 . The personal computer component diagnostic module of  claim 5 , the component functional test module is installed as an optional ROM on the motherboard. 
     
     
         8 . The personal computer component diagnostic module of  claim 5 , the component functional test module is saved in an independent optional ROM. 
     
     
         9 . The personal computer component diagnostic module of  claim 5 , the component functional test module is saved in a PCI optional ROM. 
     
     
         10 . The personal computer component diagnostic module of  claim 5 , when the bios receiving a trigger event, the component functional test for recognize the computer component status and potential problems.
