Abstract

The present invention relates to a computer system for shortening the boot time of an operating system program and a control method thereof, wherein the main memory device stores an OS driving ROM storing boot information of a system generated by the operating system program and an OS driving ROM. BIOS to suspend the operation of the operating system program to load to a specific area of the BIOS or to send resume information for resuming the operation. Therefore, the BIOS transmits suspend information to the operating system program by booting, and initializes the OS driving ROM by storing the boot information in the OS driving ROM. When system booting is performed using the initialized OS drive ROM, boot information stored in the OS drive ROM is loaded in the main memory device, and then reset information is transmitted from the BIOS to the operating system program for normal operation of the operating system program. Therefore, every time booting, booting time is saved by booting using the boot information stored in the OS rom instead of searching the system usage environment information. In addition, when the system hardware and software addition and configuration information are changed, the operating system program restores the boot information of the new system use environment to the OS drive ROM.

Description

Computer System Makes Short Of Booting Time And Control Method Having The Same

The present invention relates to a computer system for shortening the boot time of an operating system program, and more specifically, to initialize and install an OS driving ROM that stores boot information generated when the system is booted, and to drive the OS when the operating system program is booted. The present invention relates to a computer system and a method of controlling the same, which reduces boot time by loading boot information stored in a ROM into a main memory device and omitting a search for hardware and software at boot time.

A typical computer system uses the Power On Self Test process, which checks if each device connected to the system (for example, CPU, memory, graphics card, hard disk, and floppy disk) is working properly when powered on. If there is no problem, the operating system program (Operating System) is driven.

The operating system program then retrieves the set information about the hardware and software of the system to allow the system to operate. This is called booting.

The booting is performed by the CPU with the help of the BIOS, so that the CPU can modify the contents of the BIOS and use it to perform other functions. In this case, the load area of the memory used must not be invaded, and the added function must be set to operate using another area or register.

Operating system programs (such as Microsoft's Windows 95, Windows NT, etc.) have drivers or devices that control the devices that are connected to the system. They retrieve the configured information of each device at system boot. Booting takes place.

Therefore, each booting device requires a long time to search each device and the driver that controls them. Therefore, even a computer system with a high processing speed is very inconvenient because the booting speed is slow.

In order to solve the above problems, the present invention is to provide a computer system having an OS drive ROM for storing boot information generated by the operating system program and booting through it.

In addition, in order to solve the above problems, the present invention is to provide a control method of a computer system to boot using the OS drive ROM without retrieving the hardware and software configuration information of the system every time the computer system boots.

According to an aspect of the present invention for achieving the above object, a computer system using a windowing operating system program comprising: a central processing unit; Main memory; An operating system (OS) driving ROM for booting the operating system program and storing booting information loaded in a specific region of the main memory device therein; A BIOS for transmitting suspend information for suspending the operation of the operating system program and reset information for resuming operation of the operating system program to store the boot information in the OS driving ROM to the operating system program; A secondary storage device for temporarily storing the loaded boot information in an arbitrary storage area for storing the loaded boot information in response to the suspend information; When booting using the OS driving ROM, boot information stored in the OS driving ROM is loaded in an area not overlapping with an area in which other information of the main memory is loaded, and the reset information is transmitted to the operating system program.

In a preferred embodiment of this aspect, the OS drive ROM rewrites the boot information in response to a change in configuration information of hardware or software of the computer system.

In a preferred embodiment of the present invention, the BIOS may determine whether the stored boot information is modified according to whether the boot information is stored in the OS drive ROM or the configuration information of hardware and software of the computer system is changed. Stores internally whether to boot using ROM.

According to another aspect of the present invention for achieving the above object, a control method of a computer system for reducing the boot time of an operating system program using an OS drive ROM: whether boot information is stored in the OS drive ROM; Determining; If boot information is not stored in the OS driving ROM, transmitting suspend information from the BIOS to the operating system program to initialize the OS driving ROM; If booting information is stored in the OS driving ROM, determining whether to boot using the OS driving ROM; Using the OS driving ROM, loading booting information of the OS driving ROM into a main memory device; Transmitting resume information from the BIOS to the operating system program; In response to the reset information, returning to an operating state before the operating system program receives the suspend information to complete booting.

In a preferred embodiment of this aspect, the initializing step includes: loading booting information generated by the operating system program into a main memory device; Transmitting suspend information from the BIOS to the operating system program; Storing the boot information in an auxiliary memory device in response to the suspend information; Storing the stored boot information in the OS driving ROM; Rebooting.

In a preferred embodiment of this aspect, if the OS drive ROM is not used, booting by the operating system program in a general manner.

In a preferred embodiment of the present invention, if booting information is stored in the OS driving ROM, determining whether to modify the booting information of the OS driving ROM; When the boot information of the OS driving ROM is modified, the initializing of the OS driving ROM is performed.

Therefore, when the computer system is booted, the suspend information is transmitted from the BIOS to the operating system program, and the boot information loaded in the memory from the relevant data of the hard disk driver is burned into the OS drive ROM to initialize the OS drive ROM.

Subsequently, whenever a computer system is used, it is loaded into memory using boot information stored in the OS drive ROM. Then, the resume information is transmitted from the BIOS to the operating system program, and the system is booted by returning to the operation state before receiving the suspension information of the operating system program.

In addition, when the usage environment is changed by the hardware or software of the system, new boot information is generated by the operating system program again, and the new boot information is restored to the OS driving ROM.

Hereinafter, a computer system and a control method thereof for shortening a boot time of an operating system program according to an embodiment of the present invention will be described in detail with reference to the accompanying drawings.

1 is a view showing the configuration of a computer system for shortening the boot time of an operating system program according to the present invention, which is equipped with a new BIOS 112 and an OS driving ROM 114. The system includes a CPU 100, a memory 104, and a hard disk driver 116.

The memory 104 loads boot information generated by an operating system program or boot information stored in the OS driving ROM 114 in a specific region.

The BIOS 112 sets whether to store the boot information in the OS driving ROM 114. And it is set whether or not to modify the stored boot information due to the change of the setting information according to the use environment of the hardware or software of the computer system. Then, it is set whether to boot using the OS driving ROM 114. In addition, suspend information for suspending the operation of the operating system program and resumption information for resuming the operation of the operating system program are transmitted to an operating system program.

The hard disk driver 116 stores an operating system program and records the boot information in an arbitrary storage area in order to store the boot information in an OS drive ROM.

The OS driving ROM 114 burns the information loaded into the memory 104 when the operating system program is driven to store information formed as data in a storage area of the hard disk driver 116 by suspend information transmission. Initialize by burning. When the setting information of the hardware or software of the computer system is changed, rewriting for modifying the boot information is possible.

The OS program recognizes the transmission of the suspend information / result information from the BIOS 112 and applies the suspend information / result information corresponding thereto.

That is, the suspension information is provided to various device drivers so as to respond to the suspension information through tasks for controlling a plurality of hardware and software included in the operating system program. Each task that receives the suspend information then stores the current information in the device driver that it currently controls. Subsequently, the various tasks transmit information indicating that the suspension information has been received to the operating system program, whereby the operating system program informs the BIOS 112 that preparations corresponding to the suspension information are completed. The BIOS 112 then stores the boot information loaded in the memory 104 in a free area of the hard disk drive 116. Subsequently, the stored boot information is burned in order to be stored in the OS driving ROM 114.

Accordingly, when the computer system is driven by an operating system program, the computer system checks whether boot information is stored in the OS driving ROM 114 and loads the boot information into the memory 104. Therefore, when booting information stored in the OS driving ROM 114 is loaded, the BIOS 112 transmits reset information back to an operating system program. Subsequently, the operating system program returns to the system information of the operating state before the suspend information is received and sets the usage environment of the system to perform the normal operating system program operation.

Referring to FIG. 2, memory mapping at boot is shown as an example.

The memory 104 mapping includes an interrupt vector area 20 by a user or a BIOS, a work area 22 of an operating system program at boot, a BIOS area 28 and a free area 24 in which a BIOS program is loaded, and the like. Divided into

In particular, the OS drive region 26 for loading boot information stored in the OS drive 114 is loaded so as not to overlap with the BIOS information 28 and other information regions 20 and 22 loaded in the memory 104. do.

3 is a diagram illustrating a control procedure of a computer system for reducing a boot time of an operating system program according to the present invention. This program is stored in the BIOS 112, and this control is performed in the CPU 100.

Referring to the drawing, when power is supplied, it is determined whether boot information is stored in the OS driving ROM 114 at step S300 through a power-on self test (POST). If the boot information is not stored in the OS driving ROM 114, and the process proceeds to step S314 to determine whether to store the boot information in the OS driving ROM 114. Subsequently, when booting information is stored in the OS driving ROM 114, the process proceeds to step S320 to transmit suspend information from the BIOS 112 to the operating system program to initialize the OS driving ROM 114. If booting information is not stored in the OS driving ROM 114, the booting process is performed through a general booting process in step S316.

If booting information is stored in the OS driving ROM 114, the process proceeds to step S302 to determine whether the booting information of the OS driving ROM 114 is corrected. When the boot information of the OS driving ROM 114 is modified, the initializing of the OS driving ROM 114 is performed in step S320. If the boot information is not modified in the OS driving ROM 114 in step S304, it is determined whether to boot using the OS driving ROM 114. If the OS driving ROM 114 is not used, the process proceeds to step S316 and is booted in a general manner by the operating system program.

When the OS driving ROM 114 is used in step S306, boot information of the OS driving ROM 114 is loaded into the memory 104. In operation S308, resume information is transmitted from the BIOS 112 to the operating system program. In operation S310 and S312, the operating system program returns to an operation state before receiving the suspension information to complete booting in response to the reset information.

Next, FIG. 4 is a diagram illustrating a procedure of initializing the OS driving ROM 114 shown in FIG. 3, and illustrates a procedure of burning the OS driving ROM 114.

Referring to the drawing, in the initialization step S320, boot information generated through the operating system program is loaded into the memory 104 in step S322. In operation S324, suspend information is transmitted from the BIOS 112 to the operating system program. In operation S326, the boot information is stored in the auxiliary memory device 116 in response to the suspension information. In operation S328 and S330, the stored boot information is stored in the OS driving ROM 114 and rebooted.

Therefore, the computer system according to the present invention loads the boot information stored in the OS drive ROM 114 into the memory 104 every time the operating system program is booted, as described above, and uses the BIOS 112 as an operating system program. Only transmitting the resume information is performed.

In addition, when boot information, such as changing the set information of each device connected to the computer system or adding a device, is modified, the OS driving ROM 114 is initialized again through the procedure shown in FIG. 4. .

Therefore, the computer system loads boot information of the system into the memory 104 when the operating system program is started to initialize the OS driving ROM 114, that is, to write boot information, and then the BIOS ( When the suspend information is transmitted from the 112 to the operating system program, boot information loaded in the memory 104 is formed and stored as data in a specific storage area of the hard disk drive 116. Subsequently, the data is burned into an OS driving ROM 114, and the BIOS 112 transmits RESUME information to the operating system program.

Therefore, when the operating system program needs to initialize the OS driving ROM 114 or modify the information of the OS driving ROM 114 (for example, when changing or adding the set information of hardware and software of the system). Except for booting, booting time is reduced by booting using booting information stored in the OS driving ROM 114.

As described above, according to the present invention, the boot time of an operating system program is loaded by using the boot information stored in the OS drive ROM without loading the hardware and software set information of the computer system by the operating system program every time. To shorten.
