Description
Technical field
The present invention relates to the detection and the diagnostic techniques of computing machine, particularly relate to a kind of computer diagnosis method and diagnostic system of diagnosing by infrared ray.
Background technology
The mainboard diagnostic card, also be POST card (Power On Self Tst Power-On Self-Test), its principle of work is to utilize the testing result of BIOS in the mainboard (Basic Input or Output System (BIOS)) internal processes, show one by one by mainboard diagnostic card code, code implication zoom table in conjunction with diagnostic card just can be known the computer glitch place soon, especially PC (PC) machine can not the pilot operationp system, blank screen, when loudspeaker are not named, use the mainboard diagnostic card more can embody its facility, get twice the result with half the effort.
BIOS on the mainboard is when each start, the strict test of row in the time of can be to each assemblies such as the circuit of system, storer, keyboard, video section, hard disk, floppy drives, and analyze hard-disk system and dispose, to basic I/O (input and output) setting carrying out initialization of having disposed, after all are normal, reboot operating system.Its distinguishing feature is to be the separatrix whether cursor to occur, earlier critical piece is tested, and critical piece breaks down and forces machine to change shutdown over to, and display does not have cursor, and then screen does not have any reaction.Then, nonessential parts are tested if any the fault machine also continue operation, simultaneously display shows that error message breaks down when machine.When key fault appears in computing machine, there is not when demonstration on the screen, be difficult to judge the computer failure place, can insert this card in the expansion slot this moment, go up the code that shows according to card, with reference to the BIOS kind under the computing machine, find represented failure cause of this code and position by the code implication zoom table of mainboard diagnostic card again, just can know clearly guilty culprit.The function of mainboard diagnostic card is very powerful, and the ability of reporting errors by the ability that the tinkle of bells reports an error, is the essential instrument of slip-stick artist of being engaged in computer motherboard exploitation and computer maintenance considerably beyond BIOS self.
Common mainboard diagnostic card has PCI (Peripheral Component Interconnect standard) interface card, serial interface card, parallel port interface card, mainboard plate to carry diagnostic lamp etc.Wherein the mainboard plate carries diagnostic lamp and need add decoding and displaying circuit such as seven segment digital tubes on every mainboard, needs cost higher.Pci interface card is slip-stick artist's a common tool, but volume big, carry inconvenience.And along with computer technology has entered the PCI Express epoch, the living space of PCI is more and more littler.The notebook-enabled platform of Intel (Intel company) all is " mini PCI-E type " interface from " NAPA type " beginning wireless network card, and the PCI diagnostic card is because no corresponding interface is lack scope for their abilities.Serial ports/parallel port interface card and PCI diagnostic card situation are similar, and its applying frequency is on a declining curve because of the minimizing of field of employment.
So need a kind of diagnostic tool that can on most of computing machine, can both use now especially, and need control cost, preferably can not increase production cost of products.
