A method of booting a personal computer that reduces boot time and reduces power consumption. The operating system reads an operating system from an HDD 4 and stores it in the system memory 1 and the video memory 2 at the first boot. After the boot process is completed, the contents of the system memory and the video memory are stored in the inactive memory, and upon rebooting, the operating state of the inactive memory (3) is checked by the setting state of the COMS RAM (7). Inactive notes at boot by operating system of inactive memory (3) Guide reads the operating system from (3) is characterized in that the boot and stored in the system memory (1) and the video memory (2).

Description

How to boot your personal computer

The present invention relates to a booting method of a personal computer, and more particularly, to a non-volatile random access memory (NVRAM, for example, a fresh memory) by adding an operating system to the operating system from the HDD when the first operation; After loading into the memory, the contents of the system memory and video memory are stored in the inactive memory, and the next time the personal computer is loaded, the operating system is loaded from the inactive memory into the memory to reduce boot time and reduce power consumption. It's about booting.

Conventionally, the booting time was long by loading an operating system from the HDD into the system memory at the beginning of the operation of the system, and in the case of a notebook computer, a considerable amount of power was consumed by reading the HDD.

An object of the present invention to solve this drawback is to load the operating system from the HDD to the system memory in the first operation by adding an inactive memory, and then to store the contents of the system memory and video memory in the inactive memory and then to the next reboot It provides a method of booting a personal computer that loads the operating system into memory, thereby reducing boot time and reducing power consumption.

The present invention for solving the above-described drawbacks is to read the operating system from the HDD at the first boot and to store the contents of the system memory and video memory in an inactive memory after the booting process stored in the system memory and video memory is completed. While checking whether the operating system of the inactive memory is booted by the setting state of the COMS RAM at the time of rebooting, the operating system is read from the inactive memory at the time of booting by the operating system of the inactive memory and stored in the system memory and the video memory. It features a boot box.

In addition, a flag is set for indicating this in the CMOS RAM at boot time by the operating system stored in the inactive memory.

7: CMOS RAM

Hereinafter, with reference to the accompanying drawings will be described a configuration and operation according to the booting method of a personal computer according to the present invention.

1 is a block diagram according to the present invention, a system memory (1; system memory), video memory (2; video memory), inactive memory (3; flash memory), HDD (4; hard disk drive), ROM It consists of a BIOS (5; read only memory basic input output system), a CPU (6; centeral process unit unit), and a CMOS RAM (7; complementary metal oxide semiconduc-tor random access memory).

The operation of the present invention configured as described above will be described.

At the first boot, the CPU 6 reads the operating system from the HDD 4 and stores the operating system of the system memory in the inactive memory 3 after the storing process is completed in the system memory 1 and the video memory 2. The operation of storing the video image contents of the video memory 2 in the inactive memory 3 is performed.

This step is executed only once after the initial boot, and only afterwards when the operating system environment changes.

As shown in Fig. 2, the CPU 6 determines whether to boot by the operating system stored in the HDD 4 or the inactive memory 3 by external input (S21), and as in the prior art, the HDD ( If it is determined to boot by the operating system stored in 4), a flag "0" is set (S22) at a specific address of the CMOS RAM 7. However, if it is determined that booting is performed by the operating system stored in the inactive memory 3 upon rebooting, the CPU 6 sets a flag of "1" to indicate this at a specific address of the CMOS RAM 7 (S23). ).

Subsequently, when the personal computer is restarted, the CPU 6 checks the flag state of the COMS RAM 7 as shown in Fig. 3 to confirm whether to boot by the operating system stored in the inactive memory 3 ( S31).

Then, when it is set to boot by the operating system stored in the inactive memory 3, the CPU 6 reads the operating system from the inactive memory 3 and stores it in the system memory 1 and the video memory 2 to boot. (S32). However, as in the prior art, when set to boot by the operating system stored in the HDD 4, the CPU 6 reads the operating system from the HDD 4 to the system memory 1 and the video memory 2; Boot while saving (S33).

As described above, the present invention additionally installs an inactive memory for storing the operating system, and reads the operating system from the HDD and loads the contents of the system memory and the video memory in the inactive memory upon first reading the operating system from the HDD. The operating system reads from the inactive memory and loads into the system memory and the video memory to boot when stored again, thereby reducing boot time and reducing power consumption.

In particular, the present invention, such as a notebook computer, when using a small capacity portable battery or a separate battery by reducing the power consumption of the boot, it is possible to increase the use time of the notebook.
