[Embodiment] [0〇31] The following drawings are used to explain the preferred embodiment of the present invention. _2] is a flowchart of the method of the fast switching operation of the present invention. In Fig. 1, the power supply of the computer is turned on. After that, BI0S executes the booting process, for example, testing and initial setting of each hardware device of the system, that is, p〇sT, 100100246 Form No. A0101 Page 6/19 pages 1002000411-0 201229901 POST 'Power On Self Test, power supply Start self-test) program [0033] Ο [0034] [0035] ❹ When turning on the power or restarting the computer, the computer will start the POST program stored in Na, the main job is negative t to the computer hardware devices Do a good job of reducing the settings and basic tests to ensure that the computer can operate normally. For example, confirm the size of the physical memory (RAM) and hardware (10), for example, hard disk, keyboard, display, disk drive, Serial P0rt, system Wait, check if these devices are available or not. Once you have finished your own program, your domain will have its own Bios interface card (such as 'display card') in the computer to perform its own POST work. After completing the POST program, the deletion will load the boot program located on the bootable hard disk into the memory for execution. At this time, BIGS will transfer the execution right to the boot program of the computer system to start the execution of the operating system program. The computer can execute the financial system _# system, β丨Gs sets the electric job_hard body in the first booting stage, and divides the memory of the computer into the area (step S20)' as shown in Fig. 2 is the memory of the present invention. The intention is divided into several areas. In Figure 2, memory (4) is divided into zone 12, the first operating system exclusive zone 14, the second operating system exclusive zone 16 and the temporary storage zone 18 'this embodiment is based on - computer Operating two different operating systems as an illustration 'However, the description does not limit the present method, and the present embodiment is applicable to a computer operating three or more different operating systems. = Memory capacity of the area 12 is regarded as the operating system. And the maximum capacity required for the second operating system to access the traditional memory data. The first operating system 100100246 Form No. A0101 Page 7 / Total 19 pages 1002000411-0 [0036] 201229901 System exclusive area 14 and the second operating system The memory capacity of the exclusive area 16 depends on the capacity required by the first operating system and the second operating system to access the system data. The memory capacity of the temporary storage area 18 is greater than or equal to (the memory capacity of the n_d shared areas 12) 'And N is the number of different operating systems used by the computer. For example, there are two different operating systems. The memory capacity of the temporary storage area 大于8 is greater than or equal to (2-1 = 1) the memory capacity of the shared area 12, for example, three. For a different operating system, the memory capacity of the temporary storage area 18 is greater than or equal to (3-1 = 2) the memory capacity of the shared area 12, and so on. [0037] Next, the memory area of the shared area 丨2 and the first operating system exclusive area 14 is designated by the BIOS for the first operating system to access the data and execute the command (step S22). After completing the bios booting process, the computer system executes the first operating system and enters the first operating system program, and the first operating system uses the shared area 12 and the memory area of the first operating system exclusive area 4 to access the data and The command is executed (step S24). [0038] in the program of the first operating system, when a trigger event (eg, timer, software trigger, etc.) for switching the first operating system to the second operating system occurs, the first operating system is executed by the Bios to enter the standby mode ( The program of Suspend to RAM > ACPI (Advance Configuration and Power lnterface) S3) (step S26). [0039] Among them, ACPI's power management features have been applied from previous mobile computers (such as laptops) to general desktops, workstations, and servers. For example, the system may enter a very low power consumption state. These are the “sleep” and “sleep” settings available on most desktop computers. 100100246 Form No. A0101 Page 8 of 19 1002000411-0 201229901 [0040] ACPI S3: In BIOS, it is called "hanging to internal memory (such as 叩(4) to RAM/STR)", Wind after Wind〇ws χρ The 〇ws version and some Linux distributions are called "Standby".

In this state, the main memory (Ram) still has a power supply, although it is also the only device with a power supply. Because the status of the operating system, all applications, and the files that are opened are saved in the main memory, the user can restore the work to the state that they last remained stunned, that is, the computer returns from the S3 state to the main memory. The content of the body is the same as when it entered the S3 state. There are two advantages to this: the computer recovery process is faster than rebooting. Second, if any of the executing applications (opened files, etc.) have data stored in the memory, the data will not be Written on the hard drive.

In the program of the second operating system, when a trigger event (sound such as h〇tkey, timer 'soft triggering, etc.) for switching the second operating system to the first operating system occurs, as in the above, the second operation is performed by the BIG-line The program enters the standby mode (Suspend t0 RAM, ACPI S3) (step phantom 8) ο When the BIOS executes the program of the second operating system to enter the standby mode, 刖u will share the second operating system in the memory zone of the shared area 12 The conventional memory data (such as archive data), the FACS Wakhg Vector, and the second operating system backup data are stored in the memory area t of the temporary storage area (step S4G). The address of the second operating system stored in the memory area of the temporary storage area 18 is different from the first work, 100100246, form number A01〇1, 10th page, 19th page, 1002000411-0 201229901 [0048] [0049] The addresses of the f (four) storage (four) tree 18 of the camping system of the industry system, and the avoidance of the data of the second operating system covering the first operating system "Hai and other materials, This causes the program to fail when the data of the first operating system is lost when the first operating system is awakened. The Bios then advances the mth into the standby mode (step S42), and only supplies power to the memory 1 (). Then, the hardware of the respective systems of the computer is restored by the BIGS to the state at the time of the first power-on (step (10)). In the BIOS boot phase, the memory area of the shared area 12 and the first operating system exclusive area U is designated by BI〇s for use by the first operating system (step s46). The traditional memory data, the operation start address, and the first operation system backup data stored in the memory area of the temporary storage area 18 before the first operating system enters the standby mode by the B10 S are stored and shared. In the memory area of the area U (step S48). After the BIOS booting process of the above steps S44, S46, and S48 is performed, the computer system applies the traditional memory data, the operation start position, and the first operating system of the first operating system according to the memory area stored in the shared area 12. Backing up the data to execute the program of waking up the first operating system, entering the program of the first operating system, and using the shared area 12 and the memory area of the exclusive operating area 14 of the operating system by the first operating system to restore the first operating system to The data is accessed and the command is executed in a state before the switching of the operating system is triggered (step S50). Although the present embodiment operates on a computer with two different operating systems as an illustration, it is not intended to limit the present invention as long as the memory capacity of the computer is large enough. The computer can operate on three or more different operating systems at the same time, 100100246 form. No. A0101 Page II / 19 pages 1002000411-0 [0051] 201229901 The memory 10 of FIG. 2 is divided into three or more operating system exclusive areas, and the capacity of the temporary storage area is equal to or greater than (Ν-1) The capacity of a shared area, where Ν is 3 or more. The method of operating three or more different operating systems simultaneously is similar to the process steps described in Figure 1 above, and there is not much difference. [0052] An advantage of the present invention is to provide a method for quickly switching an operating system, which allows a user to enter an operating mode in an operating mode without the user having to store the operating state of the operating system in the operating device. The way to switch to another operating system, because the memory of the system memory will not be lost when entering the standby mode, can quickly switch to another operating system, and switch multiple different operating systems according to the user's needs. . The present invention has been described above with reference to the preferred embodiments and the accompanying drawings, and should not be considered as limiting. Various modifications, omissions and changes may be made without departing from the scope of the invention. BRIEF DESCRIPTION OF THE DRAWINGS [0054] FIG. 1 is a flow chart of a method for quickly switching an operating system of the present invention; and FIG. 2 is a schematic diagram of a memory of the present invention divided into a plurality of regions.
