Embodiment
As mentioned above, the invention provides a kind of computer components debugging method, before computer operating system loads as yet, carry out, can detect the function that the basic trace routine that has BIOS now can't be reached.Below will cooperate preferred embodiment to describe this computer components debugging method in detail.
Please refer to the 1st figure, it is the process flow diagram of computer components debugging method of the present invention.Step 201 is for calling out bios program, and then step 203 is the basic trace routine of executive component, and wherein, step 203 element detects substantially, for example: detect the hard disk configuration.Furtherly, the detection mode of detection hard disk configuration (is called elementary instruction in this instruction) for writing instruction (command) to hard disk controller.Hard disk controller just can return this hard disk relevant information, the pattern of this hard disk for example, and whether this hard disk supports S.M.A.R.T. (Self-Monitoring, Analysis, and Reporting Technology) function or the like.At last, the element functional test of step 205, in order to before computer operating system does not load as yet, this element functional test is for example carried out after a particular step again, wherein, particular step can be any one running or the step before step 203 element detects back and element functional test execution substantially.In this preferred embodiment with the display initialization as particular step so that after the element functional test, the result who makes things convenient for the output element functional test is on display.In addition, detect hard error possible in the computer system in advance, for example: in step 203, detected the hard disk that this hard disk has the S.M.A.R.T function, then step 205 is sent instruction (command) (being called function command in this instruction), hard disk controller just can be tested this hard disk, for example test such as rotating speed.
Please refer to Fig. 2-4, it is respectively the three kind different embodiments of element functional test module of the present invention on motherboard.The element functional test module of carrying out above-mentioned steps 205 " element functional test " is that the kenel with optionrom is implemented on the motherboard 100 of computer system.The element functional test module 110 of Fig. 2 is stored on the motherboard 100 independently option memory 108, and is arranged in 106 minutes with the basic detection module of BIOS element.Fig. 3 is stored in PCI option rom 108b (being positioned on the PCI adapter 107) for element functional test module 110, and is arranged in 106 minutes with the basic detection module of BIOS element.Fig. 4 illustrates element functional test module 110 and is stored in BIOS option rom 108a, and combines with the basic detection module 106 of BIOS element.No matter element functional test module 110 is modes of above-mentioned that a kind of enforcement, does not all influence element functional test program implementation mode.
Please refer to Fig. 5, it is a kind of element functional test module of a preferred embodiment of the present invention.Please refer to Fig. 6, it is the process flow diagram of a kind of element functional test of a preferred embodiment of the present invention.
In step 202, when central processing unit 102 (with reference to Fig. 2-4) call element functional test program, element functional test program is copied in the DRAM (Dynamic Random Access Memory) 104 (with reference to Fig. 2-4) earlier and decompresses.For reserved elements functional test program implementation space, should confirm earlier that DRAM (Dynamic Random Access Memory) 104 has enough spaces (for example, confirming the space of 512KB at least).
In step 204, can first detection computations machine system configuration, think that each step that connects down element functional test program prepares.For example, detect the specification of each hardware, could prepare the functional test program that is suitable for.This step is carried out by the detection module 112 of Fig. 5.
In step 206, carry out the function of the intrasystem PCI device of scanning computer by the scan module 118 of Fig. 5.
In step 208, carry out central processing unit MSR (Module Specific Register, special module register)/MTRR (Memory Type RangeRegister, type of memory range registers) test by the central processing unit debug module 120 of Fig. 5.
In step 210, carry out S.M.A.R.T. (Self-Monitoring, Analysis, the and Reporting Technology of hard disk by the hard disk debug module 114 of Fig. 5; From monitoring, analysis and reporting techniques) test.
In step 212, carry out the startup path testing by the path module 116 of Fig. 5, for example the startup test of network start element.
Above-mentioned step 206-212 execution there is no particular order, also can increase and decrease step according to demand.The element functional test can be by pressing special keys (for example, the button of connected system or switch) to start when using; Or after utilizing special keys to enter the BIOS system, select the menu of starting element functional test; Or whether by the basic trace routine of BIOS element, judging needs the starting element functional test.After the element functional test was finished, the result of test can be shown on the display, be output in log file and error code or with loudspeaker output audio.The user can be learnt the situation and the possibility problem of computer system by the result of test, with the main reference data as the reparation computer system.
By the invention described above preferred embodiment as can be known, use computer components debugging method of the present invention, can assist user or dealer under the situation of no operating system, the situation of detection computations machine system and possibility problem reduce the maintenance ratio that motherboard, Barebone and notebook return factory simultaneously.
Certainly; the present invention also can have other various embodiments; under the situation that does not deviate from spirit of the present invention and essence thereof; those of ordinary skill in the art can make various corresponding changes and distortion according to the present invention, but these corresponding changes and distortion all should belong to the protection domain of claim of the present invention.
