Description
Technical field
The present invention relates to the Computer Applied Technology field, be meant a kind of bootstrap technique of the system that speeds operations especially.
Background technology
Computing machine is more and more being brought into play enormous function as a kind of instrument of routine work, has become office tools and converter tools, and has become the consumption household electrical appliances in a lot of families.Only need computer starting is just passable to normal user mode for the general user, and pay no attention to the process of computing machine normal operation from the pilot operationp system to the whole operation system, therefore shorten the start-up time of computer operating system, the user be need not in the start-up course of computer operating system through tediously long wait, can be for the user bring good sensation, and increase work efficiency.
At first simply introduce the principle of work of computing machine: when computing machine normally moves, the all application programs and the subprogram of operating system all are to move in internal memory, by internal memory as intermediary, data on the hard disk and the data in the internal memory are exchanged, as long as with the data in the internal memory be set to can the operation system the related data part, computing machine just can normally move.For example, computing machine is current, and data in the internal memory are exactly the basis of computer run so just in operation system and an application program, and operation and the hard disk by data in EMS memory forms bridge like this.
Computing machine mainly contains two kinds of dormant states: S3 dormant state and S4 dormant state.S3 (Suspendto DRAM) dormant state is meant the dormant state that suspends to internal memory; S4 (Suspend to HDD) dormant state is meant the dormant state that suspends to hard disk.S3 dormant state and S4 dormant state are the industrywide standards of Advanced Program Zoom (ACPI) defined, the hardware design of computing machine with drive exploitation and be based on all that this standard realizes.Introduce the principle of two kinds of dormant states below respectively.
The principle of S3 dormant state mainly is all the computer field information before computing machine will enter dormant state, for example central processing unit (CPU) information, operation system information, application information, the relevant information of each hardware, the information such as value of related register all are stored among the internal memory.When being in the S3 dormant state, the hardware of computing machine all is in closed condition, has only internal memory still constantly to refresh under the 5VSB electric power thus supplied, to keep the integrality of internal storage location in the internal memory.When computing machine during by the wake-up of S3 dormancy wake events, S3 dormancy awakening incident such as for example keyboard wakes up, mouse wakes up, operating system be according to each computer field information of storing in the internal memory, computing machine is back to the state that enters before the S3 dormant state.For example, operating system is just being carried out the counter program before entering the S3 dormant state on a certain memory address, after waking the S3 dormancy so up, operating system directly jumps to this memory address and carries out the counter program, thereby the state after entering the preceding state of S3 dormancy and waking the S3 dormancy up is consistent.
The principle of S4 dormant state mainly is all the computer field information before computing machine will enter dormant state, for example central processing unit (CPU) information, operation system information, application information, the relevant information of each hardware, the information such as value of related register all are stored in the hard disk.When being in the S4 dormant state, the hardware of computing machine all is in closed condition.When computing machine is waken up by S4 dormancy awakening Event triggered, for example press power switch, operating system or Basic Input or Output System (BIOS) (BIOS) are according to each computer field information of storing in the hard disk, computing machine is back to the state that enters before the S4 dormant state, thereby the state that enters before the S4 dormancy and the state that wakes up after the S4 dormancy are consistent.
The user can define the condition that enters S3 dormant state or S4 dormant state as required voluntarily, and the condition of waking S3 dormancy or S4 dormancy up.
Fig. 1 enters the process flow diagram of S4 dormant state for computing machine, and as shown in Figure 1, the process that computing machine enters the S4 dormant state may further comprise the steps:
Step 101～step 104: enter S4 dormant state condition when precondition satisfies computing machine, operating system is extracted necessary computer field information in internal memory, then the computer field information of extracting is write hard disk, generate image file, and this image file is stored under a certain temp directory of operating system, computing machine enters the S4 dormant state then.
The process flow diagram of Fig. 2 for from the S4 dormant state computing machine being waken up as shown in Figure 2, may further comprise the steps the process that computing machine wakes up from the S4 dormant state:
Step 201～step 206: wake computing machine S4 dormancy condition up when precondition satisfies, BIOS carries out normal boot, carries out initial work, for example stablizes hard disk, sends instructions to relevant device etc.; The operating system channeling conduct is for example to Main Boot Record channeling conduct etc.; Operating system is loaded into internal memory with image file, and hardware state is returned to state before computing machine enters the S4 dormant state, and computing machine returns to the state that enters before the S4 dormant state.
S3 dormant state and difference between the S4 dormant state only are to store that to enter before the dormant state position of computer field information different, when waking the S3 dormancy up, operating system only needs according to each computer field information of storing in the internal memory, computing machine is back to the state that enters before the S3 dormant state; And when waking the S4 dormancy up, operating system needs earlier the computer field information of storing in the hard disk to be loaded into internal memory, then according to each computer field information of storing in the internal memory, computing machine is back to the state that enters before the S4 dormant state, therefore because the difference of computer field storage position information has caused the difference of waking the different used times of dormant state up.Usually, wake the used time of S3 dormancy up well below waking the used time of S4 dormancy up.All the time need the 5VSB power supply on the mainboard to be its power supply but the limitation of S3 dormant state is an internal memory, this point is exactly to need the 220VAC power supply to be its power supply all the time for computing machine.For internal memory, no matter be synchronous dynamic random internal memory (SDRAM) or Double Data Rate synchronous dynamic random internal memory (DDR SDRAM), will lose its canned data as long as lose the power supply supply.
The cardinal principle of in fact, S3 dormancy/S4 dormancy has all been used internal memory.For the S3 dormancy, need be the internal memory continued power, it is constantly refreshed, guarantee that the information in the internal memory is not eliminated.For the S4 dormancy, the information of preserving in hard disk is identical with relevant information in the internal memory.BIOS provides the ladder of management to computer hardware, by the operation of hardware register being realized the management to hardware.With computing machine during by the S4 dormancy awakening, only be by operating system in that dormancy defines and analyzes to S4, BIOS does not play a significant role in this process.
How to start computing machine fast, the power supply that need not that wakes the quick and S4 dormant state of S3 dormancy up is combined, i.e. the integrated application of S3 dormant state and S4 dormant state becomes a problem demanding prompt solution.

Step 401～step 403: recover the 220VAC power supply after the unexpected power down of computing machine and supply with, by register set startup BIOS that will be corresponding, show that with this action of this recovery power supply power supply is used for triggering the recovery of operation system information in the internal memory with the GPIO1 pin of CPU.Because the register corresponding with the GPIO1 pin of CPU is for its power supply by the 5VSB on the mainboard, so when computing machine recovers the power supply of 220VAC power supply, will give pulse of GPIO1 pin, this pulse meeting changes the value of the register corresponding with it, the startup of the change triggers BIOS by this register value.
Step 404～step 407:BIOS reads the image file of storing in the hard disk, and canned data in this image file is loaded into internal memory, and canned data is identical with information in the image file in the internal memory, and computing machine is in the S3 dormant state.
Mentioned image file above, the generation of image file can make the operation system information in the internal memory obtain backup, after the unexpected power down of computing machine and restoring electricity, becomes the approach that internal memory obtains operation system information.Introduce the generative process of image file below.
Operating system is for providing exchange channels between computer hardware and BIOS and the application program, therefore operating system can be considered as total application program based on computer hardware and BIOS, therefore just wherein having added the scheduling to resource managements such as memory management, file system managements, can be to have two application programs that independently, can't move simultaneously with the computer understanding with dual operating systems.At same operating system, its canned data in internal memory is identical, therefore only need to start the operating system for the first time or during operating system update, os starting BIOS extracts the operation system information of storing in the internal memory, then the image file that generates is stored in hard disk at BIOS.
Fig. 5 is for generating the process flow diagram of image file according to the present invention, as shown in Figure 5, the process that generates image file may further comprise the steps:
Step 501～step 502: computing machine enters the S3 dormant state, and BIOS judges whether current starting the operating system is to start for the first time, if, execution in step 504; Otherwise, execution in step 503.
Step 503:BIOS decision operation system is 0 still to be 1 with the value of hardware change sign, if be 0, finish the generation of image file and handles; If be 1, execution in step 504.
Step 504～step 505:BIOS extracts the relevant information of operating system in the internal memory, then the information of extracting is generated image file, and is stored in hard disk.
In addition, BIOS can utilize hard disk to deposit operation (ATA) instruction image file is placed in the hidden partition, in order to avoid artificial destruction or virus attack.
Fig. 6 is according to the process flow diagram that generates image file behind the operating system update of the present invention, and as shown in Figure 6, the process that generates image file behind the operating system update may further comprise the steps:
Step 601～step 603: when key hardware is upgraded, for example hard disk, mainboard, display card etc., operating system is carried out corresponding upgrading, reinstalls operating system, and operating system is changed to 1 with hardware change sign; Start the operating system then.
Step 604～step 609: computing machine enters the S3 dormant state, BIOS extracts the relevant operation system information of storing in the internal memory, and regenerate image file, then operating system is changed to O with hardware change sign, then image file is stored in hard disk, this locational former image file is replaced with newly-generated image file.
The content of storing in the former image file is the relevant information of origin operation system, and the content of storing in the newly-generated image file is the relevant information of the operating system after upgrading.The content of storing in the image file is only corresponding with the relevant information of operating system, and operating system does not change, and the content of storing in the image file does not just change.
In a word, the above is preferred embodiment of the present invention only, is not to be used to limit protection scope of the present invention.
