Embodiment
Your, be described as follows especially exemplified by preferred embodiment for allowing juror can more understand technology contents of the present invention.
Please refer to Fig. 1～Fig. 3 is computer hardware Organization Chart of the present invention, be example in the present embodiment with the notebook computer, and notebook computer is mainly keyboard control chip 40 (certainly about the control chip of being responsible for boot program at present, the control chip of above-mentioned responsible boot program is not limited to keyboard control chip, the chip of for example starting shooting can be designed to utilize other starting-up signal of reception, for example receive the starting-up signal that mouse transmits, reach the start purpose.), therefore following is example with keyboard control chip 40, does an explanation.
For reaching the above object, the present invention's program area that increase in keyboard control chip 40 are carried out improper boot program more.Please refer to the interior arrangement synoptic diagram of Fig. 4 about keyboard control chip 40 of the present invention, keyboard control chip 40 mainly comprises processor 41, timer 42, the device of hardware pin (being generally GPIO pins) 44 and at least one programmable memory 43 or the like, processor 41 is used for carrying out various calculation process in the keyboard control chip 40, timer 42 is used for the usefulness of timing, keyboard control chip 40 utilizes hardware pin 44 and other hardware unit to join and mutual data transmission, relevant processor 41, hardware such as timer 42 and hardware pin 44 are the emphasis of known technology and non-the present invention improvement, therefore do not give unnecessary details at this.In programmable memory 43, comprised the 51 and second firmware zone 52, first firmware zone has been arranged, the first firmware zone 51 is used for as the usefulness of the normal boot-strap of computing machine 10, if the firmware update of computing machine 10 inside goes wrong, cause and to start shooting with the first firmware zone 51, will use the usefulness of the second firmware zone 52, the part of repairing first firmware zone 51 after the start again and damaging as the improper start of computing machine 10.
Please refer to Fig. 5 and Fig. 6 internal processes synoptic diagram relevant for the 51 and second firmware zone 52, first firmware of the present invention zone, 51 burnings of first firmware zone first boot program 511, usefulness as normal boot-strap, the program that therefore complete start executive routine is arranged has for example comprised basic boot program 511a, but the program 511b of the instruction of down operation system, the program 511c of temperature detection control, the program 511d of battery charging and discharging, support the program 511e of built-in keyboard, support the program 511f of built-in indicator device and the program 511g supervisor of support and basic input/output system (BIOS) communication.In second firmware zone 52 burning second boot program 521, can't carry out at first boot program 511, or to repair, during renewal, can start 521 starts of second boot program, upgrade first boot program 511 again, therefore second boot program 521 can only comprise some necessary boot programs, include basic boot program 521a, but the program 521b of the instruction of down operation system, the program 521f supervisor of supporting the program 521e of built-in keyboard and supporting built-in indicator device, because the function of second boot program 521 can be few than first boot program 511, therefore second firmware zone, 52 shared memory spans can be designed as less than the shared memory span in first firmware zone 51.Second boot program 521 is to utilize after the basic boot program 521a start, but just can use the program 521b of the instruction of down operation system, comes correct or corrected first boot program 511 of burning.
The method that starts second boot program 521 relevant for the present invention please refer to the step of Fig. 7 relevant for boot action process flow diagram of the present invention.
Step 701:
Accept initialized program, this initialized program is to stop power supply to keyboard control chip 40 fully.With notebook computer 10 is example, and the power source that remove comprises the power lead 16 of battery 15 or external power source, and keyboard control chip 40 will initialization thus.
Step 702:
Detecting the program that whether has an abnormal condition to handle carries out.This software program that detects step can be located at second boot program 521 in second firmware zone 52, detects step and carry out this earlier by processor 41.
The content of this abnormal condition handling procedure please refer to first embodiment of step 801～step 802 and second embodiment of step 901～step 902.
If the condition of the program of reaching the abnormal condition processing is arranged, just can enter step 703, otherwise carry out step 704.
Step 703:
Start shooting with second boot program 521.
Step 704:
Start shooting with first boot program 511.
Below please refer to the first embodiment process flow diagram of Fig. 8 about the program of abnormal condition processing.
Step 801:
Do not put according to the power switch 17 of computing machine 10 earlier, after loading onto the battery 15 of computing machine 10 or being inserted with the power lead 16 that connects external power source, lasting again pushing power switch (because timer 42 can provide time data, makes software program can obtain the time that will set) more than 17 two seconds or two seconds and just decontrols power switch 17 afterwards.Wherein the time that continues pushing power switch 17 can utilize software parameter to adjust, and is not limited to two seconds; The purpose that continues 17 a period of times of pushing power switch is to be to prevent the user under unwitting situation, and mistake has been carried out second boot program 521 and can't have been started shooting normally.
Step 802:
Push primary power source switch 17 again.
This step can also be omitted in fact, as long as 801 automatic opening power directly enter step 703 in steps, the action of step 802 is because be accustomed to opening power once more according to general user.
The topmost purpose of step 801 and step 802 is because keyboard control chip 40 can detect the supply changing condition of power supply by hardware pin 44, if detect the supply changing condition (step 801 and step 802) of uncommon power supply, then know the condition of the program of reaching the abnormal condition processing.
As shown in Figure 9, the present invention is about the second embodiment process flow diagram of the program of abnormal condition processing.
Step 901:
Do not put (for example above two seconds) by at least one button 141 on the lower keyboard 14, insert power lead 16 and decontrol at least one button 141 on the keyboard 14.The purpose of this step is as step 801, at least one button 141 can be specified the button of less usefulness, or specify more than one button 141 (for example will press " A ", " D ", " G " simultaneously) to prevent the user under unwitting situation, mistake has been carried out second boot program 521 and can't have been started shooting normally.
Step 902:
Push primary power source switch 17 again.
Described as step 802, step 902 also can be omitted.
The topmost purpose of step 901 and step 902 is because keyboard control chip 40 can detect button 141 changing conditions by hardware pin 44, if detect the supply changing condition (step 901 and step 902) of uncommon power supply, then know the condition of the program of reaching the abnormal condition processing.
To sum up institute is old, and no matter the present invention is all showing it totally different in the feature of known technology with regard to purpose, means and effect, is a quantum jump, earnestly asks your juror to perceive, and grants quasi patent early, and in order to do Jiahui society, the true feeling moral just.Only must notice that the foregoing description only is illustrative principle of the present invention and effect thereof, but not is used to limit the scope of the invention.Any those skilled in the art all can be under know-why of the present invention and spirit, and embodiment is made an amendment and changes.The scope of the present invention should be as described the claim scope described.
