Abstract
After power source of computer host is turned to on and passed to power on test phase, the method uses dark and light combination of LEDs on computer keyboard to display debugging codes to inform user the current debugging executive mode. The method includes following steps: first, building checklist of debugging codes; next, receiving error message of execution, then, generating control signal from error message of execution based on checklist of debugging codes; finally, receiving the control signal, and generating combination of LEDs corresponding to error message of execution based on the signal.
Description
Technical field
The present invention is a kind of method that shows error detecting code, particularly a kind of method of utilizing the LED lamp demonstration error detecting code on the computor-keyboard.
Background technology
BIOS (Basic Input Output System) is as the term suggests mean software the most basic in the system, the program of burning in flash ROM (Flash ROM) when dispatching from the factory for motherboard.Its basic functions is exactly the basic setting value that is used for remembering computer, the user's pattern that also can come initialization system by BIOS, and the correlation parameter of hardware simultaneously.When system's one start, the testing when BIOS can start shooting (Power On Self Test) is to determine the basic configuration of system component.
The debug interface of conventional P C framework is to transmit by ISA or PCI bus, is shown on LED or the seven joint displays through detecting sign indicating number after the decoding, perhaps uses serge sound and expresses.For example: DRAM is bad to be again and again long serge sound, SRAM is bad then to be three short fast serge sound, the VGA card is bad then to be eight fast weak points sound that gurgle, so that maintenance to be provided, purposes such as test, this interface is widely used in the engineering technical personnel of industry, yet today, industrial community was emphasized after sale service and the numerous and confused so-called after sale service center of setting up, the Ji is that the client solves the problem in all System Operations with efficiency of service easily and fast, if the debug interface of present main flow will be built on the product, allow the user can show the state representation of learning system's debug running by the information of user's end, carry out technical support via telephone so that circulate a notice of the technician fast, certainly will have problems thus, at first, the cost of hardware design and the cost of material will improve, because LED or seven joint displays all belong to the outfit that adds, on set specification, need planning again to produce, and required part increases, and Material Cost also can improve relatively; Moreover, above-mentioned debug interface display device is to be built within the casing of computer, when the user meets with obstacle and must utilize this interface to know the present debug state of system, need open the casing beginning of computer and can observe present error detecting code demonstration, so often cause the inconvenience in the use.
Summary of the invention
In view of this, the present invention proposes a kind of method of utilizing the LED lamp demonstration error detecting code on the computor-keyboard, when the host computer power-on and after, utilize the light and shade combination of the LED lamp on the computor-keyboard, to show error detecting code, to inform the present debug executing state of user through the start test phase.
The present invention's technical scheme is: when the host computer power-on and through a start test phase, the light and shade combination that utilizes the LED lamp on the computor-keyboard is to show an error detecting code, and the method step of this invention includes: set up an error detecting code table of comparisons; Receive an execution error information; At this error detecting code table of comparisons of this execution error information comparison, and produce a control signal; Reaching a cresset that receives this control signal and produce according to this corresponding to this execution error message makes up.
By the disclosed method of the present invention, the user need not buy more extra equipment and get final product the known state of knowing the present debug of system, moreover, also because of the display mode that is based upon on the keyboard, make user and engineering technical personnel all can observe the state that present system carries out debug easily.
Description of drawings
Utilize the LED lamp on the computor-keyboard to show that the method for error detecting code is described in further detail as follows below in conjunction with most preferred embodiment and accompanying drawing to of the present invention:
Fig. 1 utilizes the computer input interface to show the method flow diagram of error detecting code for the present invention discloses.
Embodiment
The present invention is a kind of method of utilizing the LED lamp demonstration error detecting code on the computor-keyboard.
Please refer to Fig. 1, illustrate that the present invention discloses the method flow diagram that the LED lamp that utilizes on the computor-keyboard shows error detecting code, when the host computer power-on and through BIOS start test phase, promptly carry out POST (the POWER ON SELF TEST) self test program of front end among the BIOS, wherein formed by the test procedure of many segments among the POST.Before it will enter this section test procedure, can earlier test program code (ERRORCODE) be put into CPU AL buffer, after again with the data in the CPU AL buffer, via I/O instruction (OUT 60H, AL) be sent to keyboard controller, inform the execution test mode that the user is present through the light and shade combination that just program code (ERROR CODE) is directly utilized the LED lamp on the computor-keyboard after the decoding to show error detecting code, thereon several LED matrix can be set, generally speaking it is three, be respectively number lockled, caps lock led, and scroll lock led, the status number that can show is calculated as: 2
n(n is the number of LED lamp) calculates according to this, and general LED lamp configuration can show that then eight kinds of different systems carry out the debug state, if the debug state that needs to show presents more kinds of situations, then need increase the number of LED lamp, also can be more than three; Wherein this method step comprises and at first sets up the error detecting code table of comparisons (step 100) and be stored in the Installed System Memory, and the error detecting code table of comparisons include several execution error information with and corresponding control signal, ought receive execution error information (step 200) then, the system that is is sent when boot program runs to the obstacle address informs execution error signal (ERROR CODE), be that BIOS can be with relative diagnosis of program sign indicating number via Port 60 outputs, again at the execution error information comparison error detecting code table of comparisons, and produce control signal (step 300), last keyboard controller reception control signal and the cresset that produces according to this corresponding to execution error information make up (step 400), also the unlatching by several different cressets or the combination of closing reach the purpose of display system executing state, as:
Num?lock?led---on
Caps?lock?led---off
Scroll?lock?led---on
The situation of low memory is represented in the combination of this cresset; In case BIOS encountered problems can't continue the time in wherein any stage, the combination of LED lamp is represented to rest on last combination, allow the user learn the problem place rapidly according to this code, reach the purpose of debug, if the user can't be got rid of at the demonstration situation of cresset, also can electricity be in harmony the technician to seek advice from solution.
The above person only is the present invention's preferred embodiment wherein, is not to be used for limiting practical range of the present invention; Be all, be all scope of patent protection of the present invention and contain according to equivalent variations and modification that the present invention did.
