Technical scheme in the embodiment of the present invention is to solve above-mentioned technical matters, and general thought is as follows:
Load by starting shooting by firmware at electronic equipment in the process of the first operating system, whether detected electrons equipment meets a predetermined condition determines whether to want closed safe start-up performance and primary UEFI environmental functional, in the time that electronic equipment meets this predetermined condition, just forbid the clean boot function in firmware, like this, electronic equipment just can be installed the second operating system.For example electronic equipment wants to install Windows7 operating system, but because opening, clean boot function and primary UEFI environmental functional but cannot install, and can only load Windows8 operating system, so can utilize the method in the present embodiment implements, first start, in start process, whether meet a predetermined condition with regard to detected electrons equipment, if met, so just, from being about to clean boot function and primary UEFI environmental functional forbidding, just Windows7 operating system can be installed thus.Therefore, the method in the present embodiment does not need the alternating current of electronic equipment to break, and does not need to enter firmware yet and interface is set removes manual-lock clean boot function and primary UEFI environmental functional, so operation is very easy, easy to utilize.
In order better to understand technique scheme, below in conjunction with Figure of description and concrete embodiment, technique scheme is described in detail.
The present embodiment provides a kind of method of controlling electronic equipment, be applied in the electronic equipment with a firmware, this firmware has clean boot function and primary UEFI environmental functional, in the time of clean boot function and the unlatching of primary UEFI environmental functional, by firmware, the first operating system can be installed, wherein, electronic equipment is for example notebook computer, desktop computer, firmware is for example UEFI, the first operating system is for example Windows8 operating system.Please refer to Fig. 1, the method comprises:
Step 101: start shooting by firmware at electronic equipment and load in the process of the first operating system, whether detected electrons equipment meets a predetermined condition;
Step 102: in the time that electronic equipment meets predetermined condition, clean boot function and primary UEFI environmental functional in forbidding firmware, make electronic equipment that the second operating system can be installed, and wherein, the second operating system is different from the first operating system.
Wherein, the second operating system is for example Windows7/XP/Linux, certainly, can be also other operating systems.
Next the implementation process of the method will be introduced in detail, first, in step 101, for example user supresses the start button on electronic equipment, electronic equipment just starts to enter boot program, be responsible for start load operation system by firmware, in the present embodiment, start shooting by firmware at electronic equipment and load in the process of described the first operating system, can be to complete in firmware initialization, prepare the moment of guiding the first operating system, also it can be the moment after loading the first operating system and the failure of the second operating system, also it can be the moment in firmware initialization electronic equipment storage unit, it can certainly be the moment that can detect at other, then in these cases, whether detected electrons equipment meets a predetermined condition, and the content wherein detecting in the different moment has difference, and predetermined condition itself also has difference, and this will describe in detail in the back.
Then, in the time that electronic equipment meets predetermined condition, just perform step 102, forbid clean boot function and primary UEFI environmental functional in firmware, make electronic equipment that the second operating system can be installed.
In the first embodiment, step 101 is specially by firmware loads the first operating system and the second operating system all when failure, the entrance that starts all operations system is all when failure, just detect the on off state of clean boot function and primary UEFI environmental functional, if the result detecting shows that clean boot function and primary UEFI environmental functional are all in the time of opening, just explanation cannot start the operating system because these two functions unlatchings cause, so at this moment just illustrate that electronic equipment has met this predetermined condition, so just can self-closing safety start-up performance and primary UEFI environmental functional, and then restart electronic equipment, electronic equipment just can start the second operating system by firmware so.
In concrete implementation process, in firmware, can add one to switch fast the module that firmware is set, this module can show that failure information is to user, and a shortcut can be provided, the setting that makes user can a key switch firmware.For example, in the time that the result detecting shows clean boot function and primary UEFI environmental functional all in opening, can show and " not find any operating system by the display unit of electronic equipment.Press any key repeated priming sequence.Or press ' L ' key and download optimization setting to support legacy operating system and to restart computing machine " such prompting; user sees after such prompting so; just can press " L " key on keyboard; then electronic equipment generates illegal instruction; self-closing safety start-up performance and primary UEFI environmental functional; further, after closing, restart electronic equipment.In another embodiment, also can not by certain button on keyboard, but button on a shell that is arranged on electronic equipment, user is as long as seeing after similar prompting, just can press the button on shell, then electronic equipment generates illegal instruction, forbidding clean boot function and primary UEFI environmental functional.In other embodiments, as the switching key of this class of button on above-mentioned " L " key and shell, can also be other forms, the application is not construed as limiting.
Certainly, in the time of practice, also can not use above-mentioned switching key, but a timer is set in electronic equipment, in the time that the result detecting shows clean boot function and primary UEFI environmental functional all in opening, start timer and start timing, also can show information described above simultaneously, also can show will be in the schedule time simultaneously, for example self-closing safety start-up performance and primary UEFI environmental functional after 5s, so in the time that 5s is arrived in timer timing, will generate an illegal instruction, then can be based on this illegal instruction, clean boot function and primary UEFI environmental functional in forbidding firmware, after further closing, can restart electronic equipment.
By the method in the present embodiment, alternating current does not need first to break one time, user can be in the situation that not entering firmware, just can fast setting clean boot function and primary UEFI environmental functional, electronic equipment upper just can normal load while once starting or the second operating system is installed, so easy and simple to handle, user-friendly.
Foregoing description detect result be clean boot function and primary UEFI environmental functional be open state, in a further embodiment, when the result detecting is that clean boot function and primary UEFI environmental functional are while being the state of closing, represent so really not have in current electronic equipment the operating system that can start, can show so and " not find any operating system.Press any key repeated priming sequence." such information, user can continue by any key so.
In a second embodiment, electronic equipment is connected with a storage unit, for example CD, step 101 is specially in the time that firmware starts this storage unit, detect guidance field and the UEFI boot of this storage unit, when the guidance field of this storage unit is the guidance field of the second operating system and while there is not UEFI boot, represent that electronic equipment meets this predetermined condition, so just can perform step 102.
Specifically, although because under the first operating system schema, be under the pattern of clean boot function and the unlatching of primary UEFI environmental functional, firmware can not be from traditional optical disk start-up, but firmware but still has the ability of the whole CD content of read-write, so can be by firmware in start detection CD, detect guidance field and the UEFI loader(UEFI boot of CD), if CD exists traditional, there is not again UEFI boot in the boot section of the second operating system simultaneously, represent that so this CD is traditional CD, so at this moment just represent that electronic equipment has met this predetermined condition, can perform step 102, clean boot function and primary UEFI environmental functional are closed, can make start next time time, firmware can guide and complete the function that the second operating system is installed from CD.
In concrete implementation process, also can be as in the first embodiment, in firmware, can add one to switch fast the module that firmware is set, this module can display reminding information to user, and a shortcut can be provided, make user can one the key setting of switching firmware.For example, when the guidance field of this storage unit is the guidance field of the second operating system and while there is not UEFI boot, can on the display unit of electronic equipment, show " find a conventional optical disc; enable tradition support and again from this optical disk start-up computing machine? ' being '/'No' " such information, after user presses " Y " key on keyboard, electronic equipment generates illegal instruction, self-closing safety start-up performance and primary UEFI environmental functional, further, restart electronic equipment after closing.In another embodiment, also can not by certain button on keyboard, but button on a shell that is arranged on electronic equipment, user is as long as seeing after similar prompting, just can press the button on shell, then electronic equipment generates illegal instruction, forbidding clean boot function and primary UEFI environmental functional.In other embodiments, as the switching key of this class of button on above-mentioned " Y " key and shell, can also be other forms, the application is not construed as limiting.
Certainly, in the time of practice, also can not use above-mentioned switching key, but a timer is set in electronic equipment, be the guidance field of the second operating system and while there is not UEFI boot when detecting the guidance field of this storage unit, start timer and start timing, also can show information described above simultaneously, also can show will be in the schedule time simultaneously, for example self-closing safety start-up performance and primary UEFI environmental functional after 5s, so in the time that 5s is arrived in timer timing, will generate an illegal instruction, then can be based on this illegal instruction, clean boot function and primary UEFI environmental functional in forbidding firmware, after further closing, can restart electronic equipment.
By the method in the present embodiment, alternating current does not need first to break one time, user can be in the situation that not entering firmware, just can fast setting clean boot function and primary UEFI environmental functional, electronic equipment upper just can normal load while once starting or the second operating system is installed, so easy and simple to handle, user-friendly.

Option represents that firmware will continue to guide operating system normally wherein " to continue guiding ", so in the time that user has selected this option, what firmware do not do with regard to, but continues normal guiding the first operating system; What the option that " enters firmware menu setting " represented link is the page that arranges of firmware, and in the time that user selects this option, firmware is just written into the page is set.
And in the time that user opens " selecting guiding entrance/equipment " option, just represent to have received this scheduled operation, and then represent that electronic equipment meets this predetermined condition, so just perform step 102, clean boot function and primary UEFI environmental functional are closed.In a further embodiment, after step 102, also show the choice menus of traditional guiding entrance/equipment, this time, user can select from CD-ROM drive, USB device or other device starts in this menu, because now clean boot function and primary UEFI environmental functional are closed, so user can start the operating systems such as Windows7/XP, i.e. the second operating system normally.
Equally, in the time that user selects to start the option of " recovery system ", also represent to have received this scheduled operation, and then also represent that electronic equipment meets this predetermined condition, so at this moment perform step 102, closed safe start-up performance and primary UEFI environmental functional, and then carry out restore funcitons.Because it may be traditional version that the key on electronic equipment recovers, i.e. the second operating system, also be likely UEFI version, i.e. the first operating system, therefore only close primary UEFI environmental functional guarantee and support simultaneously, in addition, even UEFI version, also not necessarily there is clean boot signature, so also want closed safe start-up performance.
By the method in the present embodiment, the alternating current that do not need first to break a time, and user do not need to enter firmware yet, just can fast setting clean boot function and primary UEFI environmental functional, so operation is very easy, easy to use.
Further, can change by a button state of this zone bit, for example, on the external casing with electronic equipment of this button, be connected with GPIO status-pin, often press once, the level of GPIO status-pin will change; Or change according to the time length of pressing, also can change according to compression number, those skilled in the art can go to set concrete form according to actual needs.
In other embodiments, this zone bit can be also status register, can certainly be connected to the value that changes status register on circuit board by external button, certainly, those skilled in the art also can adopt other zone bit form and button form, and the application is not restricted.
By this external button, user just can control the state of zone bit very easily, so further facilitated user's operation.
