Description
Technical field
The present invention relates to a kind of method that writes down test procedure.
Background technology
For the user of computer, opening the power supply of computer, almost is the thing that must do every day to start computer, but computer is showing operating system (Operating System, be called for short: before start-up picture OS), carried out those processing on earth? I believe that most of users may not be clear.For can understand computer from opening power before start-up picture occurs, computer carries out those processing, makes following simple explanation now:
In the start-up course of traditional computer, the very perfect start oneself testing mechanism of a cover is arranged.For the computer that adopts Award BIOS, it begins to start shooting in several seconds of self-testing mechanism from receiving power supply, just can finish more than 100 detection step.
At first, cross the Cheng Qian at the explanation launch computer, must understand two key concepts: first is Basic Input or Output System (BIOS) (Basic Input Output System, be called for short: BIOS), in fact Basic Input or Output System (BIOS) is exactly to be encapsulated in the chip of this computer, it is be responsible for to coordinate and the batch processing of management computer hardware, and provides lowest-order, the most direct hardware controls for this computer.In many hardware of traditional computer, all be provided with Basic Input or Output System (BIOS), and modal hardware as; Motherboard (being also referred to as system's Basic Input or Output System (BIOS)), display card, integrate electronic type driving interface (Integrated Drive Electronics, be called for short: IDB), personal computer system interface (Small Computer System Interface, be called for short: SCSI), networking card (Network Interface Card) ... wait and some other equipment, all there is Basic Input or Output System (BIOS), wherein system's Basic Input or Output System (BIOS) is the part that we will illustrate, because the start-up course of computer is to carry out under the control of system's Basic Input or Output System (BIOS).The boot program of system's Basic Input or Output System (BIOS) generally is in the ROM (read-only memory) (ROM) that is stored at motherboard, so even at shut down of computer or after losing power supply, boot program can not disappear without foundation yet.
Second storage address that key concept is storer usually is equipped with the storer with a constant volume in the computer, and for the ease of the access of the central processing unit of computer, each bit group (byte) of these storeies all has been endowed an address.For example: the address realm of 32 megabit tuples (32MB), be to use sexadecimal number to represent, just it stores the address by 0～1FFFFFFH, wherein the low side IMB storer of 0～FFFFFH is very special, because processor with 32 bits, its can direct access the storer maximum have only 1MB, therefore the low side 640 kilobit tuples (KB) of this 1MB are called as basic storage, to keep by A0000H～BFFFFH and use and store the address to display card, storing the address in addition then is retained to the Basic Input or Output System (BIOS) of computer all hardware by C0000H～FFFFFH and uses, wherein system's Basic Input or Output System (BIOS) generally takies last 64KB or more more space, and the Basic Input or Output System (BIOS) of display card is generally storing address C0000H～C7FFFH place, integrate the Basic Input or Output System (BIOS) of electronic type driving interface, then storing address C8000H～CBFFFH place.
Understood after these key concepts, below we will describe computer in detail and be unlocked behind the power supply before the start-up picture that enters operating system the start-up course of computer:
The first step: when we press the power switch of computer, the power supply that power supply unit provided of this computer, to begin to motherboard and the power supply of other hardware, the voltage that provided this moment is still unstable, its motherboard control chip group (Chipset), can send and keep a replacement (RESET) signal to its CPU (central processing unit) (CPU), allow the CPU (central processing unit) initialization.By the time power supply begins (never to be stabilized to stable voltage behind the stable power-supplying, its process is very of short duration), this control chip group is just cancelled reset signal, identical, restart computer if manually press replacement button set on the computer panel, that is petty unclamp this replacement button after, this control chip group will be cancelled reset signal, make CPU (central processing unit) immediately from storage place FFFFOH, begin execution command, this stores the address in the address realm of the Basic Input or Output System (BIOS) of system, no matter be Award BIOS or AMI is BIOS, be placed on a just jump instruction here, jump to start-up code place real in system's Basic Input or Output System (BIOS).
Second step: the start-up code of system's Basic Input or Output System (BIOS), at first to be exactly selftest (the Power On Self Test that starts shooting, be called for short: POST), the main task of start selftest is that can whether some key equipments in the detection system exist and operate as normal, as storer and display card etc.Because, the testing process of this start selftest is before the display card initialization, therefore, if in the process of start selftest, found some fatal errors, when not finding storer or storer that problem is arranged (start selftest process is only checked the 640K conventional memory), can't on display, be revealed, at this moment the system boot selftest can come the reporting errors situation by the sound horn of this computer, and these loudspeaker have been represented wrong type with the length and the number of times of its sound that sends.So under general normal condition, start selftest process is carried out very soon, we almost can't feel this process.
The 3rd step: system's Basic Input or Output System (BIOS) next, the Basic Input or Output System (BIOS) of display card will be searched, the start address of ROM (read-only memory) of depositing the display card Basic Input or Output System (BIOS) is usually at the C0000H place, system's Basic Input or Output System (BIOS) finds after the video card Basic Input or Output System (BIOS), call its setup code, finish the initialization of display card by the display card Basic Input or Output System (BIOS).Most of display cards can demonstrate the information of some display cards usually on display screen in this process; as: contents such as production firm, graphic chips type, the capacity of display; first picture of being seen when just we generally start shooting; but this picture almost flashes across; the Basic Input or Output System (BIOS) of the display card that also has has been used delay function, so that the user can see the information of demonstration clearly.Follow the Basic Input or Output System (BIOS) program that system's Basic Input or Output System (BIOS) can be searched other hardware, the setup code that will call the Basic Input or Output System (BIOS) inside of these hardware after finding equally comes these hardware of initialization.
The 4th step: searched after the Basic Input or Output System (BIOS) of all other hardware, system's Basic Input or Output System (BIOS) will show its startup picture, comprising contents such as the type that system's Basic Input or Output System (BIOS) is arranged, sequence number and version numbers.Simultaneously the motherboard message code can appear in its lower left corner, display bottom, comprises the recognition coding of control chip group model, motherboard of version date, the motherboard of system's Basic Input or Output System (BIOS) and vendor code etc.
The 5th step: then system's Basic Input or Output System (BIOS) will detect the type and the frequency of operation of CPU (central processing unit), and testing result is presented on the display, the type and the dominant frequency of the CPU (central processing unit) that our start that Here it is is seen.Next system's Basic Input or Output System (BIOS) begins all memory spans of Test Host, and the simultaneously tested capacity numerical value that goes out of display-memory, the just memory counter of generally always rapidly rolling in this display the first half on display.And this process we can in Basic Input or Output System (BIOS) is provided with, select few " fast detecting " consuming time or many " complete detection " modes consuming time.
From the above, in second step of the start-up course of computer, because the testing process of this start selftest was carried out before this display card initialization, the display that is to say computer is in the testing process of this start selftest, be to demonstrate any picture, and under general normal condition, this start selftest process is carried out very soon, we almost can't feel this process, so make user also can't carry out corresponding error exception if found that some mistakes can't be revealed on this display this moment, at this moment, this start selftest is to come the reporting errors situation by the sound horn of this computer.
But, these loudspeaker are represented various type of errors with the length and the number of times of its sound that sends, and according to (as: the AMI of different vendor, Award or Phoenix) Basic Input or Output System (BIOS) of manufacturing, respectively this type of error is not necessarily represented according to the length and the number of times of same sound, this brings considerable puzzlement in the use for the general user, especially, general for the user who is unfamiliar with computer, may not understand the length of all sound of each manufacturer and the type of error of number of times representative fully, even if general computer engineer is the handbook of the corresponding type of error of asonant length and number of times, also can't understand type of error, in addition, the manufacturer of computer is when development, must carry out debug at all parts of computer, and in the start selftest process of computer, this moment is if make a mistake, this type of error is to have reference value, but it also can't directly offer research staff's reference, and the most important thing is the length and the number of times of the sound that these loudspeaker send and be not easy memory and resolution, so, if can be with a kind of more convenient, direct misregistration type mode, make the user of computer can pass through the read error type, and know the type of present mistake, believe be popular find pleasure in see.
Summary of the invention
Because traditional computer utilizes the length and the number of times of the sound that its loudspeaker send to represent various type of errors, and be not easy to remember and differentiate, the inventor is through the permanent research and experiment of making great efforts, finally development and Design goes out a kind of method that writes down test procedure of the present invention, make the user of computer can pass through the read error type, and know the type of present mistake.
