[embodiment]
First embodiment:
As shown in Figure 1, a kind of method that starts computer system may further comprise the steps:
Among the step S110, start powers on.
Among the step S120, detect guiding device, generate the guiding device tabulation in the power-on self-test stage.After the start; BIOS (Basic Input Output System, Basic Input or Output System (BIOS)) gets into the power-on self-test stage (PowerOn SelfTest, i.e. POST stage); Detect all guiding devices in the power-on self-test stage, obtain type and residing position of guiding device etc.Detected guiding device is recorded in the guiding device tabulation.
Among the step S130, read boot sequence change zone bit, generate corresponding boot sequence tabulation according to boot sequence change zone bit and guiding device tabulation.In one embodiment, be provided with boot sequence change zone bit and corresponding boot sequence rule in advance, and boot sequence is changed zone bit be stored in the BIOS chip.Defined the guiding priority of each guiding device in the boot sequence rule according to user's boot sequence demand (being that which type of boot sequence guiding the user hopes with).
In first embodiment, in advance guiding device is sorted out, the guiding priority of dissimilar guiding devices is set; The guiding priority of the guiding device of same type further is set, owing to be connected on the guiding device of same passage, the prefix of the device name that in BIOS, shows is consistent; For example; Guiding device title prefix is " HDD:3S ", and expression is that (HDD generally includes the IDE hard disk to HDD, the SATA hard disk; CF card and DOM dish) slave unit of the 3rd passage of equipment, therefore the characteristics of guiding device title prefix capable of using are to the guiding device definition guiding priority of same type.
The different corresponding different boot sequence rules of boot sequence change zone bit, for same guiding device, defined guiding priority maybe be different in the different boot sequence rules.For example; According to the height ordering according to guiding priority in the boot sequence rule of user's boot sequence demand customization is IDE hard disk, CF card and USB flash disk successively, and the height ordering according to guiding priority is CF card, IDE hard disk and USB flash disk successively in another boot sequence rule.According to boot sequence change zone bit, get access to corresponding boot sequence rule, then can the guiding device in the guiding device tabulation be sorted according to the guiding priority of guiding device, generate corresponding boot sequence tabulation.
Boot sequence change zone bit default value is 0, and in the guiding device tabulation of generation, the number of guiding device is indefinite, but inserts the data consistent of the guiding device in the current system with reality.Because boot sequence change zone bit is stored in the BIOS chip, find wrong and boot sequence, security and better reliability that change defines in advance in the time of can or not carrying out complete inspection because of the power down of CMOS register.
Among the step S140, according to boot sequence tabulation load operation system.Because the boot sequence that generates tabulation is consistent with the boot sequence rule that defines in advance, meets the boot sequence demand of customization, and can both dynamically generate boot sequence tabulation after start powers at every turn.When the user increases and decreases guiding device or original guiding device and is connected on different passages; Can both generate the boot sequence tabulation automatically; Need not the user gets into BIOS and resets the acquiescence boot sequence; Improved the convenience that starts computer system, be specially adapted in the unattended automatic industrial production.
Second embodiment:
As shown in Figure 2, in a second embodiment, the method detailed process that starts computer system is following:
Among the step S210, start powers on.
Among the step S220, detect the degree of stability of guiding device in the power-on self-test stage.The degree of stability of guiding device is meant that guiding device breaks down or potential problem is arranged.
Among the step S230, generate the guiding device tabulation, and the guiding device that degree of stability is lower than first threshold is got rid of outside the guiding device tabulation.BIOS detects all guiding devices in the power-on self-test stage; Be lower than the guiding device of first threshold for degree of stability; Promptly this guiding device has fault or potential problem is arranged; Then this guiding device does not add in the guiding device tabulation, thereby has guaranteed that the guiding device in the guiding device tabulation is the higher equipment of degree of stability, has avoided the mistake that when subsequent load operating system, possibly occur.
Among the step S240, read boot sequence change zone bit, obtain predefined boot sequence rule according to boot sequence change zone bit.As stated, the different corresponding different boot sequence rules of boot sequence change zone bit, the boot sequence rule can customize according to user's boot sequence demand.
Among the step S250, the guiding device in the guiding device tabulation is sorted, generate corresponding boot sequence tabulation according to the boot sequence rule.Owing to defined the guiding priority of guiding device in the boot sequence rule, can the guiding device in the guiding device tabulation have been sorted according to the height order of guiding priority.
Among the step S260, according to the boot sequence tabulation load operation system of correspondence.It specifically is first guiding device (promptly guiding the highest guiding device of the priority) channeling conduct from the boot sequence tabulation of correspondence earlier; When needs carry out loop test to guiding device; Automatically restart system, guide one by one according to the boot sequence in the boot sequence tabulation.
The 3rd embodiment:
As shown in Figure 3, the 3rd embodiment is on the basis of first, second embodiment, and is after the load operation system, further comprising the steps of:
Among the step S310, judge whether current guiding device supports the SMART technology, if then get into step S320, otherwise get into step S330.Current guiding device is the guiding device that current operating system belongs to; The SMART technology is self-monitoring, analysis and reporting techniques (Self-Monitoring Analysis andReport Technology), and guiding device is supported the SMART technology, and BIOS can monitor current guiding device in real time.
Among the step S320, current guiding device is monitored.
Among the step S330, carry out user application.If the guiding device at current operation system place is not supported the SMART technology; Then directly carry out user application; User application can be the operation of setting in advance, and for example the operating software instrument is tested, changed zone bit etc. through software change boot sequence after guiding device goes wrong guiding device.Should be noted that; Because user application can carry out flexible configuration according to user's needs; When guiding device is supported the SMART technology, also can carry out the user application of configured in advance, like the operating software instrument current guiding device is tested etc.
Among the step S340, judge whether current guiding device breaks down, if then get into step S350, otherwise return step S320.BIOS is in the process that current guiding device is monitored in real time; Judge whether guiding device breaks down, and breaks down then to do handled, do not break down and explain that then current guiding device operation is normal; Then return step S320, BIOS continues current guiding device is monitored.
Step S350, BIOS change boot sequence change zone bit.One preferred embodiment in, when current guiding device broke down, BIOS changed zone bit with boot sequence and adds 1, if boot sequence change zone bit surpasses maximal value, then boot sequence was changed zone bit and was made as 0.The maximal value of boot sequence change zone bit is the quantity of predefined boot sequence rule.
Step S360 is restarted system.After restarting system; Return the step that start powers on, BIOS detects guiding device again, and will have fault and the guiding device that potential problems are arranged to get rid of outside the guiding device tabulation; When promptly the current guiding device in step S340 breaks down; After restarting system, can not join in the guiding device tabulation, and owing to boot sequence change zone bit is modified; BIOS can go the guiding device in the guiding device tabulation is sorted according to the boot sequence rule of the amended boot sequence change of correspondence zone bit, generates corresponding boot sequence tabulation.
For example, after start powered on first, the boot sequence change zone bit that reads was 0; The guiding device that defines in the corresponding boot sequence rule just is followed successively by IDE hard disk, CF card and USB flash disk according to guiding priority, and the guiding device at current operation system place is the IDE hard disk, determines the IDE hard disk and supports the SMART technology; Therefore BIOS monitors the IDE hard disk in real time; When detecting the IDE hard disk and break down, it is 1 that BIOS revises boot sequence change zone bit, the starting system of laying equal stress on.Restarting starts shooting after the system powers on, and whether BIOS can detect guiding device in the power-on self-test stage has fault, and find that the IDE hard disk breaks down this moment, then only comprises CF card and USB flash disk in the guiding device tabulation, and the IDE hard disk no longer is recorded in the guiding device tabulation.Amended boot sequence change zone bit is 1; The guiding device that defines in the corresponding boot sequence rule just is followed successively by USB flash disk, CF card and IDE hard disk according to guiding priority; Because the IDE hard disk has been excluded outside the guiding device tabulation; The boot sequence tabulation of the correspondence that therefore generates is USB flash disk and CF card, promptly at first from USB flash disk guiding, load operation system.
Because when guiding device is supported the SMART technology; When detecting current guiding device and breaking down, BIOS removes to change boot sequence change zone bit automatically, after next time, start powered on, can out of order guiding device be got rid of outside the boot sequence tabulation of correspondence; When therefore current guiding device breaks down; Also need not manual intervention, the BIOS acquiescence boot sequence that can automatically switch, the user does not need to get into again BIOS the acquiescence boot sequence is set; Improved convenience, be specially adapted in the unattended automatic industrial production.
The 4th embodiment:
As shown in Figure 4, the 4th embodiment also can may further comprise the steps after the load operation system on the basis of first, second embodiment:
Among the step S410, judge whether current guiding device supports the SMART technology, if then get into step S420, otherwise get into step S480.
Among the step S420, current guiding device is monitored.When current guiding device was supported the SMART technology, BIOS monitored current guiding device in real time.
Among the step S430, judge whether current guiding device breaks down, if, then get into step S440, otherwise return step S420, continue guiding device is monitored in real time.
Among the step S440, BIOS reports to the police, and waits for user's response.BIOS can provide alarm mechanism, reminds the current guiding device of user to break down.
Among the step S450, judge whether receive that in Preset Time the user responds, if then get into step S480, otherwise get into step S460.
Among the step S460, BIOS change boot sequence change zone bit.When not receiving that the user responds in the Preset Time, BIOS revises guiding change zone bit automatically, and specifically: BIOS changes zone bit with boot sequence and adds 1, if boot sequence change zone bit surpasses maximal value, then boot sequence is changed zone bit and is made as 0.The maximal value of boot sequence change zone bit is the quantity of predefined boot sequence rule.
Among the step S470, restart system.As stated, restart system after, BIOS detects guiding device again, out of order guiding device then is excluded outside guiding device tabulation, out of order like this guiding device can not be recorded in the boot sequence tabulation of generation yet.
Step S480 carries out user application.User application is the predefined operation of user, as carry out data repair from appointed equipment and standby system medium to appointed equipment.User application can carry out flexible configuration according to the actual requirements.
Step S490, the interface that provides through BIOS receives the boot sequence change zone bit that the user is provided with.Among this embodiment, BIOS also can provide the interface that boot sequence change zone bit is set, and the user changes the setting of zone bit in proper order through this interface channeling conduct; If the user is not provided with; Then do not process,, then receive the boot sequence change zone bit that the user is provided with if the user is provided with boot sequence change zone bit; Get into step S470, restart system.As stated, restart the boot sequence change zone bit that then is provided with after the system and generate corresponding boot sequence tabulation according to the user.
When current guiding device breaks down; Can revise boot sequence change zone bit automatically by BIOS, the switches default boot sequence also can be provided with boot sequence change zone bit according to self demand by the user flexibly; The switches default boot sequence, so the switches default boot sequence is more flexible.The user is provided with boot sequence change zone bit and can realizes through interface read write command under SMIPORT (the IO port of triggering system management interrupt) that BIOS provides; Promptly from the BIOS chip, read boot sequence change zone bit and boot sequence is changed zone bit and write in the BIOS chip; Need not extra software and hardware support, provide cost savings.
The above embodiment has only expressed several kinds of embodiments of the present invention, and it describes comparatively concrete and detailed, but can not therefore be interpreted as the restriction to claim of the present invention.Should be pointed out that for the person of ordinary skill of the art under the prerequisite that does not break away from the present invention's design, can also make some distortion and improvement, these all belong to protection scope of the present invention.Therefore, the protection domain of patent of the present invention should be as the criterion with accompanying claims.
