The invention relates to the technical field of computers, in particular to a computer system and method for quickly starting up, a computer readable recording medium and a computer program product.

When the power of the computer is turned on, the central processing unit (CPU) executes the basic input output system (BIOS) in the flash memory on the motherboard, and initializes the chipset and the memory subsystem. . The CPU will decompress the BIOS from the flash memory to the main memory of the system and start performing functions such as system initialization and system diagnostics.

The BIOS is integrated with the hardware system (burning BIOS program instructions in the IC), and the early BIOS is stored in ROM (read-only memory) and cannot be modified. Because the size and complexity of the BIOS increase over time, and the hardware update speed is accelerated, the BIOS must be constantly updated to support the new hardware, so the BIOS is stored in the EEPROM, so that users can easily update the BIOS.

The present invention will be further understood by those of ordinary skill in the art to which the present invention pertains. .

1 is a schematic block diagram of a computer system according to a first embodiment of the present invention. In the first embodiment, computer system 10 includes a CPU (Central Processing Unit) 12 and a system memory 14. One block of the system memory 14 stores a BIOS 16, wherein the system memory 14 stores the block of the BIOS 16 as a non-volatile memory.

When the computer system 10 executes the booting process, the system memory 14 is initialized by the hardware. After the system memory 14 is initialized, the CPU 12 can access the BIOS 16 code in the system memory 14 and is executed by the CPU 12. The BIOS 16 code is used to boot the computer system 10.

2 is a schematic block diagram of a computer system in accordance with a second embodiment of the present invention. In the second embodiment, computer system 10 includes a separate battery 18 in addition to CPU 12 and system memory 14. A BIOS 16 can be stored in one of the system memory 14 of the random access memory (RAM) and the independent battery 18 supplies power to the system memory 14.

When the computer system 10 is in the off state, the independent battery 18 supplies power to the system. The memory 14 is stored, so that the BIOS 16 code stored in the system memory 14 is not lost due to the shutdown of the computer system 10. When the computer system 10 executes the booting process, the system memory 14 is initialized by the hardware. After the system memory 14 is initialized, the CPU 12 can access the BIOS 16 code in the system memory 14 and is executed by the CPU 12. The BIOS 16 code is used to boot the computer system 10.

3 is a schematic block diagram of a computer system in accordance with a third embodiment of the present invention. In the third embodiment, the computer system 10 includes a power management module 20 in addition to the CPU 12 and the system memory 14. A BIOS 16 can be stored in a block of the system memory 14 of the RAM, and the power management module 20 can supply power to the system memory 14 after the computer system 10 is powered off.

When the computer system 10 is in the off state, the power management module 20 executes a program of Suspend to RAM, so the code of the BIOS 16 stored in the system memory 14 is not lost due to the shutdown of the computer system 10. . When the computer system 10 executes the booting process, the system memory 14 is initialized by the hardware. After the system memory 14 is initialized, the CPU 12 can access the BIOS 16 code in the system memory 14 and is executed by the CPU 12. The BIOS 16 code is used to boot the computer system 10.

The Suspend to RAM status is referred to as STR. As the name suggests, STR is to store the working state data of the computer system before entering the STR into the system memory. In the STR state, the power supply continues to supply power to the most necessary devices such as system memory to ensure that data is not lost, while other devices are turned off, and the power consumption of the computer system is extremely low. Once the Power button (host power switch) is pressed, the computer system is woken up and immediately reads data from the system memory and resumes the working state before the STR. System memory reads and writes very fast, so the time it takes to enter and leave the STR state is only a few seconds.

4 is a flow chart of a method for quickly booting a computer system according to a first embodiment of the present invention. In the first embodiment, when the computer system 10 is in the off state, the independent battery 18 supplies power to the system memory 14 (step S22). When the Power button is pressed, the computer system 10 starts the booting process and initializes the system memory 14 by hardware (step S30). Next, the CPU 12 accesses the code of the BOOS 16 in the system memory 14 (step S32). Then, the program code of the BIOS 16 is executed by the CPU 12 to perform the booting process of the computer system 10 (step S34).

Since the computer system 10 is in the off state, the independent battery 18 of the computer system 10 will supply power to the system memory 12, so that the BIOS 16 in the system memory 14 will not be lost when the computer system 10 is turned off, as shown in FIG.

FIG. 5 is a flowchart of a method for quickly starting up a computer system according to a second embodiment of the present invention. In the second embodiment, the pre-stored BIOS 16 is in the block of the non-volatile memory in the system memory 14 (step S24). The remaining steps in the second embodiment are the same as steps S30, S32, and S34 in the first embodiment, and the description thereof is omitted here.

Since the system memory 14 stores the blocks of the BIOS 16 as non-volatile memory, the BIOS 16 in the system memory 14 will not be lost when the computer system 10 is turned off, as shown in FIG.

FIG. 6 is a flowchart of a method for quickly starting up a computer system according to a third embodiment of the present invention. In the third embodiment, when the system memory 10 is in the off state, power is supplied from the power management module 20 of the computer system 10 to the system memory 14 (step S26). The remaining steps in the third embodiment are the same as steps S30, S32, and S34 in the first embodiment, and the description is omitted here.

Since the power management module 20 executes the memory wake-up procedure when the computer system 10 is powered off, the power management module 20 supplies power to the system memory 14, thus in the computer system. When the BIOS is turned off, the BIOS 16 in the system memory 14 is not lost, as shown in FIG.
