Method for storing and restoring data of a graphic device

A method of restoring data of a graphic device, comprising:

• a segment examining step of examining a video graphics array basic input/output system to determine where a read only memory basic input/output system is mapped in an option read only memory area of a system memory map when changing from a hibernation state into a normal state;
• a function calling step of calling a video electronics standards association function for storing a video graphics array internal register of the graphic device, the video electronics standards association function being a video electronics standards association basic input/output system screen setting function supporting a screen mode number and input/output for each graphic device;
• a memory restoring step of restoring memory data of said graphic device from the data contained in a graphic memory and previously stored in an auxiliary storage device in order to restore a previous operating state of the hibernation state of the graphic device;
• and
• a register restoring step of restoring a chipset hardware operating state, including random access memory digital to analog converter data and video graphics array register information.

A computer having a graphic device, the computer comprising:

• a cental processing unit connected to the graphic device;
• a memory connected to the graphic device;
• the central processing unit examining a video graphics array basic input/output system to determine where a read only memory basic input/output system is mapped in an option read only memory area of a system memory map when changing into a hibernation state;
• the graphic device including a video graphics array internal register, the central processing unit calling a video electronics standards association function for storing the video graphics array internal register of the graphic device, the video electronics standards association function being a video electronics standards association basic input/output system screen setting function supporting a screen mode number and input/output for each graphic device;
• the central processing unit storing in the memory a chipset hardware operating state, including random access memory digital to analog converter data and the video graphics array internal register information after calling said video electronics standards association function;
• and
• the graphic device including a graphic memory, the central processing unit accessing the video graphics array internal register by examining the graphic memory contained within the graphic device and storing graphic memory data of said graphic memory in the memory.
