Embodiment
The user can be in the process of opening computer system, enter BIOS and set menu voluntarily the BIOS setting value is made amendment, these BIOS setting values can be recorded in the CMOS (Complementary Metal Oxide Semiconductor) of computer system, and (Complementary Metal-Oxide-Semiconductor is CMOS) in the storer.Yet when the user has done wrong setting (for example CPU overclocking or magnitude of voltage set wrong) accidentally, the user can remove content in the CMOS memory by the jumper wire device (jumper) on the adjustment motherboard.Thereafter when opening computer system again, BIOS just can carry out the initialization operation of each nextport hardware component NextPort of computer system with the systemic presupposition value.
At Basic Input or Output System (BIOS) (Basic Input Output System, when BIOS) carrying out the initialization operation of computer system, must (Complementary Metal-Oxide-Semiconductor, CMOS) the BIOS setting value in the storer be carried out the setting and the detecting operation of hardware with reference to being stored in CMOS (Complementary Metal Oxide Semiconductor).If can when the BIOS setting value is wrong, finish initialization operation with the systemic presupposition value automatically, certainly will be able to avoid situation about can't start shooting because of the setting value mistake.The present invention is based on above-mentioned viewpoint and then develops a kind of starting-up method of.In order to make content of the present invention more clear, below the example that can implement according to this really as the present invention especially exemplified by embodiment.
Fig. 2 is the process flow diagram according to the starting-up method shown in one embodiment of the invention.See also Fig. 2, at first shown in step 210, when the user pressed power key with the unlatching computer system, the BIOS that is stored in the flash ROM (flash ROM) just can be loaded into storer, and prepared to begin the nextport hardware component NextPort of computer system is carried out initialization and checked operation.
In step 220, at first the keyboard that is connected to computer system is carried out initialization operation.In more detail, behind the power supply of a unlatching computer system, at first enable the function that keyboard receives the button input, receive the input signal that user's pressing keys is produced by keyboard according to this.And when receiving input signal, just the kind according to input signal determines whether that needs change (for example deletion or change) originally was stored in the content in the CMOS memory.At last, the forbidding keyboard receives the function of button input, just makes keyboard can't receive and discern any input signal.
Next, for correct parameter is checked and set to the state to each nextport hardware component NextPort of computer system, is in regular turn to central processing unit, chipset, storer in step 230 by BIOS to step 260, and computer peripheral equipment carries out initialization operation, is able to normal operation to guarantee these nextport hardware component NextPorts after the start operation is finished.Wherein, peripherals comprises keyboard, mouse, all utilize serial port to be connected to peripheral assembly, the temperature sensor of computer system, and the rotation speed of the fan sensor or the like.Therefore in step 260, will again keyboard be carried out more complete initialization operation.
After treating that above-mentioned initialization operation is all finished, but the nextport hardware component NextPort of expression computer system is by test and operate as normal, shown in step 270, operating system is written into random access memory, and (Random Access Memory is RAM) to finish the start operation of computer system at last.
Present embodiment is before BIOS carries out the initialization operation of central processing unit, determines whether that according to the received input signal of keyboard needs change the content of CMOS memory.In computer system structure now, CMOS memory has write down many BIOS setting values, and caing be compared to similarly is basic settings such as the speed of frequency, storer of central processing unit or voltage.The user can comply with its custom or demand, enters BIOS and sets menu so that these setting values are made amendment.Yet can the correctness of BIOS setting value will normally start computer system and cause direct influence.In view of the above, following embodiment illustrates how to pass through to adjust the order of hardware initialization, and then guarantee no matter whether the BIOS setting value is correct, all can normally open each step of computer system.
Fig. 3 is the process flow diagram according to the starting-up method shown in the another embodiment of the present invention.See also Fig. 3, at first shown in step 310, open the power supply of computer system, loaded BIOS to storer will prepare to begin to carry out the hardware initialization operation this moment.
In step 320, at first enable the basic function of input interface.In the present embodiment, input interface for example is the keyboard that is connected to computer system, and the function that keyboard is activated for example is the function that receives the button input.That is to say whether by enabling the function of keyboard, can judge has any button to be pressed at present, and which button the button that is pressed is.
Next shown in step 330, by the input interface receiving inputted signal that is activated.In the present embodiment, input signal can be to push the button pressed incident (keypress event) that keyboard produces because of the user.Behind receiving inputted signal, just shown in step 340, judge whether this input signal is signal specific.Wherein, signal specific for example is the button pressed incident corresponding to specific keys (for example Insert key).Can judge through above-mentioned steps whether the user in the process of starting shooting, pins specific keys.
If input signal is signal specific (that is the user is pushing specific keys at present), then shown in step 360, the content in the CMOS memory of change computer system.Just change the BIOS setting value that sets by the user.In the present embodiment, the mode of change BIOS setting value comprises removing or revises the pairing summation (check sum) of checking of BIOS setting value.
Then in step 361,, close the input interface function of before being enabled in order to ensure ensuing initialization operation can correctly be carried out.At this moment, keyboard will be can produce reaction to any button input, and therefore whether the user is still pushing button and can not impact ensuing initialization operation.
After above-mentioned steps, BIOS will be in regular turn carries out initialization to the nextport hardware component NextPort of computer system.At first, shown in step 363, carry out the initialization operation of central processing unit.When the initialization central processing unit, must from CMOS memory, read earlier relevant BIOS setting value.Yet, because the summation of checking corresponding to the BIOS setting value is changed in CMOS memory, central processing unit judges that in view of the above the BIOS setting value is wrong, so BIOS just can carry out initialization operation with systemic presupposition value (for example preset value of central processing unit).
Similarly, in following step 365 to 369, changed to the numerical value that does not meet the BIOS setting value, so BIOS can carry out the initialization and the checked operation of chipset, storer and peripherals equally with the systemic presupposition value owing to check summation.The initialization operation for the treatment of all hardware assembly shown in step 370, is written into storer to finish the starting-up method of computer system with operating system after all having finished.
What deserves to be mentioned is, in the present embodiment, treat the complete unlatching of computer system after, also the systemic presupposition value can be write back CMOS memory, to replace the BIOS setting value of record originally.Need just be removed CMOS by the jumper wire device of adjusting on the motherboard (jumper) compared to tradition, present embodiment makes resets more convenient that the BIOS setting value becomes.
Please get back to step 340, after judging whether input signal is signal specific, suppose that input signal is not signal specific (being that the user does not push specific keys), just shown in step 350, earlier previous input interface function of opening is closed.Then BIOS just can carry out the initialization operation of nextport hardware component NextPort to be stored in BIOS setting value in the CMOS memory.
The initialization of nextport hardware component NextPort as step 351 to shown in the step 357: at first when the initialization central processing unit, set, and check the buffer of central processing unit or flag etc. whether correct (step 351) with the central processing unit frequency in the BIOS setting value.Then, with the BIOS setting value (step 353) set and checked to the buffer of chipset equally, and detection of stored device (step 355), and with each peripherals (step 357) of BIOS setting value initialization computer system.In the present embodiment, the peripherals of computer system can be keyboard, mouse, all utilize serial port to be connected to peripheral assembly, the temperature sensor of computer system, and the rotation speed of the fan sensor or the like, do not limit its scope at this.Shown in step 370, after the initialization of nextport hardware component NextPort is finished, be written into operating system at last intactly to open computer system.
Under general situation, BIOS can carry out initialization operation with the BIOS setting value that is stored in the CMOS memory.In the present embodiment, even if the user has imported wrong numerical value when revising the BIOS setting value, and then make computer system normally to open, the user only need continue pushing the specific keys on the keyboard and restarting computer system, BIOS is when carrying out initialization operation, just can come nextport hardware component NextPort is checked or set with the systemic presupposition value, and wrong BIOS setting value also can after finishing, be updated to correct systemic presupposition value in start.
In sum, the described starting-up method of the foregoing description has changed the initialization order of nextport hardware component NextPort, read CMOS memory with the initialization central processing unit before, the part function of at first enabling keyboard is to detect user's input, supress specific keys as long as detect the user, just come central processing unit and other hardware are carried out initialization operation with the systemic presupposition value.Thus, no matter the user has or not when revising the BIOS setting value and makes a mistake, and by each step of the foregoing description, can guarantee that all computer system can normally open, and the situation of avoiding in view of the above normally opening computer system because of the BIOS setting value is wrong produces.
Though the present invention with preferred embodiment openly as above, so it is not in order to limit the present invention.Those of ordinary skill under any in the technical field under the situation that does not break away from the spirit and scope of the present invention, can carry out various changes and modification.Therefore, protection scope of the present invention is as the criterion with the scope of the claim that proposed.
