Description
Technical field
The present invention relates to computer realm, particularly relate to a kind of method and device of selecting to start computer system.
Background technology
Along with popularizing of computing machine; PC (personal computer) market increasingly competitive; For realizing the increment and the differentiation of product; PC manufacturer all can be for the user provides accompanying software, and some accompanying software is (for example the saving software etc.) that operates in outside the basic operating system, in order when realizing the accompanying software operation, to avoid the interference of basic operating system; PC producer generally all provides the environment of double startup, makes the user can select to start accompanying software or startup basic operating system in this way.
Therefore can carry out the double startup mode that dual system is selected startup; Become the current very important demand of PC producer; And just must before basic operating system starts, take control for the selection that realizes dual system starts; Common way has two kinds at present, and a kind of is to be installed in the control that MBR (MBR) comes to take in advance system start-up through the double startup module with PC producer oneself exploitation; Another kind of way is that the INT 19H (bootstrap routine) that the double startup module with PC producer oneself exploitation is embedded in BIOS (Basic Input or Output System (BIOS)) calls the control of to take in advance before system start-up.
Except the startup power of taking system in advance, another important link is exactly how to let the user select the startup of dual system, and the most keyboard that is connected the PS2/USB interface that all is based on is realized at present.Function key of predefine on keyboard just; Like F2; When the double startup module starts, get into the accompanying software system through the display prompts user by this function key, if the user will not start basic operating system by this function with the double startup module in official hour; If the user has pressed this function key, will get into the accompanying software system.
The shortcoming of this scheme (selecting to get into the scheme of dual system through keyboard function key) is:
1) user interface of this function is not very directly perceived, is unfavorable for the propaganda of producer and user's use;
2) wait for that the time interval that the user selects is generally not long, the probability of user misoperation higher (when do not know button, also do not know press the how many times key effective);
3) in the internationalization process, there is compatibility issue in the keyboard of this scheme and zones of different, and development difficulty is slightly high.
Summary of the invention
The purpose of this invention is to provide a kind of method and device of selecting to start computer system, the double startup method that solves prior art can not adopt standard interface, the technical matters of poor compatibility.

Embodiment
For making the object of the invention, technical scheme and advantage clearer, will combine accompanying drawing and specific embodiment to describe the present invention below.
The present invention a kind ofly selects the method that starts to a plurality of systems of computing machine, the mode that provides a kind of dual system to start when computer starting.
The present invention is in the direct manually operated double-starting switch key of computing machine outer setting ability; On & off switch connects the standard interface of computing machine through control module and controls the state of said standard interface; The double startup module that is arranged on computer-internal need to confirm the system that starts through the state that detects said standard interface, thereby before startup, selects the system that will start according to the state of on & off switch.
Said standard interface is the standardized interface that computing machine generally has; For example USB, com port etc.; The present invention will be mainly with serial ports particularly the com port in the standard serial port be that example describes; Those skilled in the art can learn the situation of the standard interface of other types thus, as long as the standard interface of other types can also can be detected by the double startup module by Be Controlled unit change state.With reference to shown in Figure 1, double-starting switch key 21 connects the standard serial port 10 of computing machine through control module 22.In an embodiment, standard serial port is the COM (COM) of 9 pins, and the definition of 9 pins is seen shown in the table 1.The embodiment of the invention utilize the 4th (bit4, CTS) with the 5th (bit5 DSR) representes the state of switch., CTS and DSR indicate to get into PC accompanying software system when being 1 simultaneously.Therefore, after on & off switch 21 was pressed, the 4th and the 5th of control module 22 control criterion serial ports 10 was 1 (logic is) simultaneously, just started the accompanying software system after this moment, the double startup module detected this kind situation, otherwise started normal basic operating system.
Table 1, com port 9 pin marks be justice certainly

On & off switch of the present invention is arranged on the position that the computing machine external energy is observed directly, and said position comprises: the front panel of main frame, the front surface of display and/or keyboard.In the time of on being arranged on keyboard, on & off switch is to be different from keyboard and the independent key that is provided with.
Fig. 2 is the flow chart of steps of the inventive method, and is as shown in the figure, the present invention includes following steps:
Step 101 before the computer system starting, loads the double startup module;
Step 102, the scanning serial ports;
Step 103 powers on for the control module between this serial ports and the double-starting switch key;
Step 104 is carried out delay process;
Step 105, the double startup module reads this com-state;
Step 106 judges whether the bit4 of this serial ports and bit5 are 1 simultaneously, is execution in step 107 then, otherwise execution in step 108;
Step 107 starts accompanying software system of PC producer, and the double startup flow process finishes.
Step 108 judges whether current serial ports is last serial ports that can scan, and is execution in step 109 then, otherwise execution in step 110;
Step 109 scans next serial ports, forwards step 103 to;
Step 110 starts basic operating system, and the double startup flow process finishes.
By on can know, adopt the advantage after this programme to be:
1, the on & off switch of this device embodies at the front panel of PC, and it is clear to identify, and is beneficial to propaganda;
2, through the switching of on off state, which system the user can select to get into easily, and the probability of maloperation reduces greatly;
3,, realize simple, compatible good because of adopting standard interface.
The above only is a preferred implementation of the present invention; Should be pointed out that for those skilled in the art, under the prerequisite that does not break away from the principle of the invention; Can also make some improvement and retouching, these improvement and retouching also should be regarded as protection scope of the present invention.
