摘要： The present invention provides a control method for switching display between a plurality of OSs as well as a computer system. The method comprises: detecting that the currently displayed guest operating system (GOS) is required to be switched from a first GOS to a second GOS; determining whether the first GOS satisfies a preset switching condition, and switching the currently displayed GOS to the second GOS if the preset switching condition is satisfied, and otherwise, prohibiting the switching from the currently displayed GOS. With the method and the computer system, it is possible to avoid picture distortion or blurring or system collapse in switching display between a plurality of OSs.

摘要： The present invention provides a method and a computer system for sharing a graphics card among multiple Operation Systems (OSs). The method includes: detecting a first GOS to be displayed, the first GOS being a primary GOS or one of at least one secondary GOS; determining the kind of the first GOS, so that different display control register bank(s) and graphics card memory resources are allocated to the first GOS depending on whether it is a primary GOS or a secondary GOS; controlling the display control register bank(s) allocated to the first GOS to connect to a display output port; obtaining display contents based on the graphics card memory resources allocated to the first GOS; and displaying the display contents based on display mode parameters in the display control register bank(s) connected to the display output port. According to the present invention, it is possible to share the graphics card among the multiple OSs without modifying the drivers of the primary GOS.
