Does embedded controller receive the power key signal that is pressed and the key of function key? (step 101), wherein embedded controller can for example be general I/O (the General Purpose Input Output by being electrically coupled to keyboard circuit, GPIO) pin, signal with the receiving function key, then, by button decoding operation, can judge the key of the function key that is pressed.
When embedded controller receives the key of the power key signal that is pressed and function key, embedded controller is according to the operating system (step 102) of the key decision desire startup of the function key that is pressed, wherein embedded controller can for example be according to the predefined table of comparisons, according to the operating system of key decision desire startup.
Then, embedded controller notice basic input/output (Basic Input Output System, BIOS) start the operating system (step 103), wherein the order assigned according to embedded controller of basic input/output loads Master Boot Record (MBR), and Master Boot Record contains disk segmented table and necessary start executive routine code, and start executive routine code can be searched the disk segmented table and cuts apart with the disk of finding out in the use, and control passed to start sector on disk is cut apart in the use, again the operating system that is activated is loaded on the start sector.
When after embedded controller starts, not receiving corresponding function key signal, then carry out a multi-boot option program (step 104) by computer.
Next, computer is carried out a menu program code, to show the menu (step 105) of the operating system that can load on display.
Judge by embedded controller whether keyboard has the button (step 106) that is pressed, wherein embedded controller can for example be to see through to detect general I/O (the General PurposeInput Output that is electrically coupled to keyboard circuit, GPIO) whether the signal of pin changes, with the button that judges whether to be pressed, then, by button decoding operation, can judge the button that is pressed is general button or function key.
When embedded controller detects when a button is pressed, timer picks up counting, and embedded controller then judges whether to reach a schedule time (for example, 5 seconds or 10 seconds) (step 107) according to timing result.
