Problems solved by technology

Because most hardware devices have contextual relations, when implementing a certain function, a series of I / O operations are required on the hardware, and these I / O operations are not allowed to be interrupted. Therefore, the same hardware, Cannot be used by multiple operating systems at the same time
Because in the operating system of the virtual computer, only the virtual hardware can be seen, and these virtual hardware can access the direct hardware through the driver of the real hardware, so at the same time, there is only one operating system accessing the real hardware. Such an operation also makes the virtual hardware performance in the virtual computer very low.

Embodiment Construction

[0029] In order to make the above objects, features, and advantages of the present invention more comprehensible, preferred embodiments are specifically cited below and described in detail with accompanying drawings.

[0030] In this preferred embodiment, the given external device that the computer has is the graphics card that is usually configured in the computer as an example for illustration. The same method is used to achieve the purpose of allowing multiple operating systems of the computer to use predetermined peripherals in time.

[0031] The multiple operating systems that the computer has are directly installing multiple operating systems into the same computer.

[0032] Such as figure 1 As shown, the computer of this preferred embodiment has two operating systems, namely the first operating system (OS1) 10 and the second operating system (OS2) 20, both operating systems use the same graphics card 30, two management modules 11 , 21 are respectively used to manage O...

Abstract

The present invention belongs to the technical field of computer multi-operation system, and in particular relates to a method for time-sharing use of determined external equipment by a plurality of operation systems, which is suitable for the computer with the plurality of operation systems. Each operation system of the computer is provided with a management module used for managing the use state of the determined external equipment in the operation system, so as to solve the problem that when the plurality of operation systems access the determined external equipment simultaneously, the determined external equipment can not be normally used because of the context relation of hardware, so that the hardware performance of the computer can keep a good state all the time. The whole process does not need restart so as to save time and bring convenience to users.

Description

technical field [0001] The invention belongs to the technical field of computer multi-operating systems, and in particular relates to a method for multiple operating systems to use predetermined peripherals in time-sharing. Background technique [0002] In order to facilitate different work or life content on one computer, computer users often install different operating systems on one computer to meet such requirements. For example, users install Linux and Windows operating systems on one computer respectively. The traditional method of switching between different operating systems is to switch between different operating systems by restarting and selecting a different operating system, but the restarting process takes a long time to switch between operating systems, which is very uncomfortable for users Convenience. [0003] With the development of virtual technology, using some software, such as Virtual PC, can allow users to run multiple operating systems on one compute...
