Method for fast resuming computer system and computer system

A computer system, comprising:

• a central processing unit executing an operating system;
• a chipset;
• a system memory;
• a storage device, wherein when the computer system is in a shutdown state, the storage device stores a system memory data of the system memory and a used system memory block address table before the computer system enters the shutdown state;
• a basic input output system, wherein when the computer system is in a shutdown state and is resumed from the shutdown state, the basic input output system:
• starting a fast boot built-in program of the basic input output system, according to the used system memory block address table, to sequentially read the stored system memory data from the storage device and write the read system memory data into the system memory with a use of an optimized read-and-write block size as a read-and-write unit;
• making the computer system to enter a suspended state;
• and
• resuming the computer system from the suspended state.
