Abstract
A method of storing and restoring graphic data of a graphic device by using a VGA (video graphics array) VESA function in a computer system having a hibernation function, includes: a segment examining step of examining the VGA basic input/output system in order to know where the ROM BIOS is mapped in an option ROM area of a system memory map when changing into a hibernation state; a function calling step of calling the VESA function for storing the VGA internal register of the graphic device after executing the segment examining step; a register storing step of storing the chipset hardware operating state, including RAMDAC data and the VGA register information, after calling the VESA function; and a memory storing step of determining the VGA register so that access of a CPU is possible by examining a graphic memory contained within the graphic device and storing the graphic memory data in an auxiliary storage device after executing the register storing step. This allows the storing and restoring of graphic data by expanding the kind of graphic device to be supported without changing the contents of the BIOS when supporting the hibernation function of a different graphic chipset.
