Description
Technical field
The present invention is about the self checking method of a kind of Basic Input or Output System (BIOS) (BIOS), particularly a kind of method that obtains Basic Input or Output System (BIOS) (BIOS) self-detection result.
Background technology
The BIOS POST that general computer carries out, the Full Name in English of BIOS is Basic Input/OutputSystem, and Chinese is a Basic Input or Output System (BIOS), and the Full Name in English of POST is Power-On Self Test, and Chinese is that the system boot oneself detects.For when the user in when start, by the performed a kind of testing tool of BIOS.BIOS POST comprises following steps usually.Motherboard is after energized, and system is at first come inner each equipment is checked by (PowerOn Self Test, power-on self-test) program.Because the computer hardware of computer a lot (comprising internal memory, interruption, expansion board), whether the duty that therefore will detect these equipment is normal.This process is carried out one by one, BIOS manufacturer has all provided a detection of code (be called POST CODE promptly start shooting self-detection of code) to each equipment, when certain setting is detected, at first the POSTCODE with correspondence writes 80H (address) diagnostic port, when this Equipment Inspection is passed through, then then give the POST CODE of another setting, this setting is tested.If certain testing of equipment is not passed through, then this POST CODE can remain at the 80H place, trace routine also can be ended, and warn according to fixed alarm song, BIOS manufacturer has also done definition respectively to alarm song, and different BIOS manufacturers, different devices break down, and its alarm song also is different, we can tell guilty culprit according to the difference of chimes of doom.
The POST self-checking detection process is roughly: power supply-CPU-ROM-BIOS-System Clock-DMA-64KB RAM-IRQ-display card etc.Detect display card process in the past and claimed the critical component test, if critical component has problem, computer can be in suspended state, is called the core fault traditionally.Another kind of fault is called nonessential fault, detected display card after, computer will be provided with etc. the above internal memory of 64KB, I/O port, floppy drive, keyboard, PnP device, CMOS and detect, and show various information and error reporting on screen.Under normal circumstances, the POST process is carried out very soon, and we almost can't feel this process.
But it should be noted that, at present when the self check of other computer of remote monitoring, detection of code or error message code that the error reporting that shows on debug card (Debug Card) or the screen mostly only points out the 80H place to keep, can't allow user's wrong reason that comes into plain view, could understand but need the detection of code that provides through manufacturer or error message code to separate meter reading.For example see also Fig. 1, show that traditional monitoring client learns the synoptic diagram of detection of code from long-range self check computer.The examining report that is traditional computer screen display 10 that shows among the figure, and the detection of code that needs collocation manufacturer to provide is separated meter reading 20 and just why is learnt testing result.
In addition, mainly contain AWARD company, AMI company and PHOENIX company (follow-up AWARD merges with PHOENIX) owing to produce the manufacturer of motherboard BIOS at present, the BIOS that different vendor produces, its self check number of rings define or screen subsequent on the detection of code that shows be inconsistent, so the motherboard Bios produced of different vendor just needs different detection of code or error message code to separate the information that meter reading could the correct POST of understanding testing result representative.
Comprehensive the above, just can understand present user if no detection of code is separated meter reading or separated meter reading with the detection of code of wrong manufacturer, just can't understand or the wrong detection information that transmits when understanding launch computer BIOS POST, concerning the user, bring inconvenience, therefore just have the space of further improvement.
Summary of the invention
The present invention mainly is to provide a kind of method that obtains Basic Input or Output System (BIOS) (BIOS) self-detection result, being applied to a display device and a self check computer links up, the self check computer is during start-up system start oneself's detection (BIOSPOST), utilize the inventive method, the user need not use detection of code or error code to separate meter reading, just can directly learn the testing result of self check computer, solve the existing problem of prior art substantially so can use.
Therefore, for reaching above-mentioned purpose, the disclosed a kind of method that obtains Basic Input or Output System (BIOS) (BIOS) self-detection result of the present invention, being applied to a remote computer and a self check computer that contains display device links up, when the self check computer desires to carry out system boot oneself's detection (BIOS POST), the method comprises the following step: a device of self check computer carries out before the oneself detects, and the detection narration of corresponding intrument is seen through an address write remote computer; Reach when discovery is wrong in the oneself who installs detects, the detection of corresponding intrument is narrated through this address write remote computer, and be presented on the display device.

Embodiment
POST is a computer system for can normal operation, a basic function of when design, being considered, and partly whether assembly is intact available can to test each when purpose is electric power starting, and whether some equipment is not loaded onto.The content difference of different equipment selftests, common equipment has host computer and printer can do the function of selftest, host computer is mainly tested is that whether size, the internal memory function whether intact, keyboard of internal memory is complete, whether kind and kenel, interruptable controller and the timer of kind, hard disk and the floppy drive of video card be intact, if when adapter was set and main frame conflicts to some extent, the information that also can give a warning maybe can't be started shooting.
Therefore, carry out the manufacturer of remote information service in the rear end for some, whether or some are in the long-range manufacturer that will carry out self-checking for some computers that promptly will dispatch from the factory, can be directly and correctly understand the result that the self check computer detects fast and just become an important problem.
And the present invention is when carrying out the BIOSPOST self-checking at the self check computer of linking up with a remote computer that contains display device, this remote computer obtains a preferred approach of self check computer BIOS POST testing result, and it need not use detection of code and separate the information that POST testing result representative just can be correctly understood in meter reading.
See also Fig. 2 and Fig. 3.Fig. 2 is the method flow diagram of a preferred embodiment of the present invention, and Fig. 3 is for according to a preferred embodiment of the present invention, and display device is learnt the synoptic diagram of error message from the self check computer.
General computer comprises in the preposition step of carrying out BIOS POST: when pressing initiate key (power switch), the control of system is just transferred to BIOS and is finished, because this moment, voltage was also unstable, the mainboard control chip group can be sent and keeps a RESET (replacement) signal to CPU, allow the CPU initialization, wait for the POWER GOOD signal (power supply is ready to signal) that power supply sends simultaneously.After power supply begins stable power-supplying (never being stabilized to stable process certainly also is of short duration moment), chipset just removes the RESET signal (if the Reset button of manually pressing on the computer panel is restarted machine, chipset will remove the RESET signal when unclamping this button so), CPU just begins execution command from address FFFFOH at once, this address is in the address realm of system bios, no matter be Award BIOS or AMI is BIOS, be placed on a just jump instruction here, jump to start-up code place (step 201) real in the system bios.
And in a preferred embodiment of the present invention, the thing that the start-up code of system or self check computer BIOS at first will be done is being carried out POST (Power On Self Test exactly, system boot oneself detection) before each stage of (step 203), or refer to before each device is detected, can directly see through an address to the narration that should install detection of code and write remote computer, this address for example is 80H (step 202), therefore when this device makes a mistake in detection (step 204), just can be about this Device Testing narration directly through for example writing remote computer for the address of 80H, and be presented on its display device (step 205), for example as shown in Figure 3, it is a preferred embodiment of the explanation of error 30 sent of a self check computer, it is different from shown in Figure 1, and traditional testing result has only shown the error message code.
Otherwise if this device does not make a mistake (step 204) in detection, the oneself that just can continue next device detects (step 206).
Wherein for a device, detection of code can have a lot, comprises the test action of thin portion or test zone etc., and therefore corresponding detection narration also can have a lot, and and unrestricted each device the detection of code or the explanation of one correspondence only can be arranged.
The device that above-mentioned self check computer detects for example is internal memory, keyboard, video card, hard disk, floppy drive, interruptable controller or timer.
Above-mentioned display device for example is to have LCD (LCD), display of organic electroluminescence (OLED), organic polymer electroluminescent display (OPLED) or light emitting diode indicator (LED), or the screen of a computer, be connected with the self check computer for the transport module of USB (universal serial bus) (USB) and for example can utilize.
The transmission path of above-mentioned self check computer end and display device for example is 80H/COM/LPT/USB.
Because the present invention directly provides display apparatus side, the details of self check computer self-detection result are separated meter reading so the user needn't go for the error message code of corresponding manufacturer, and the comparison of also being careful just can be learnt the meaning of error message code representative.
And store to detect in collocation on the hardware of narration, only need ROM (read-only memory) (ROM) with former 256KB to expand in fact and get final product, the preferable 512KB that can be.
On the other hand, when POST successfully finishes systems inspection, will continue to carry out the program after the start; And the computer that carries out self check is wrong as finding, will handle by two kinds of situations: then shut down for catastrophic failure (critical fault), can not provide any prompting or signal because various initialization operations are not also finished this moment; Then provide prompting or audible ringing signal is given near-end or long-distance user for noncritical failure, wait for that the user deals with.
