Description

How to boot a computer system with low latency {COMPUTER SYSTEM BOOTING METHOD WITH LOW LATENCY}

The present invention relates to a computer system, and more particularly, to a control method of a computer system having various additional functions such as a communication modem and an alarm having an automatic response service function. .

Computer systems are widely used in many industries, such as banks, general offices, factories, and laboratories. In addition, as personal computers have been widely spread and various multimedia functions have been added to personal computers, personal computers can be usefully used at home. As personal computers are widely used in homes, the concept of home automation system using personal computers has emerged. At present, a system for integrating and controlling a large number of electronic devices in a home and integrating administrative control from a personal computer is being developed.

For example, a computer system equipped with a communication modem having an answering service function is used as an answering service system for making an out-of-office answering function at home. FIG. 1 is a flowchart sequentially illustrating a process of automatically waking up by receiving a ring signal in a general computer system having a ring wakeup function. Referring to FIG.

Referring to Fig. 1, when the computer system is in the power off state, in step S10, the modem apparatus determines whether a ring signal is received over the telephone line. When the ring signal is received, the flow advances to step S20 to power on the computer system. When the computer system is powered on, the boot process by the Basic Input Output System (BIOS) is performed in step S30, and then the boot process by the operating system (OS) is performed in step S40. When the booting process by the BIOS and the OS is completed, in step S50, an application program that performs the autoresponder function is executed to perform the autoresponder function.

However, there is a problem in that the computer system is powered on and thus has a long latency until the corresponding application is loaded and thus does not immediately respond to the reception of the ring signal. Of course, if the computer system is running all the time, an immediate response is possible, but in this case, there is a problem of too much unnecessary power consumption by the computer system.

As such, a computer system used as a home automation system has a long latency until a specific application is executed in response to an external situation. Therefore, there is a need for a home computer system with a relatively short latency that can respond more quickly to external situations.

Accordingly, it is an object of the present invention to provide a booting method of a computer system that has a short latency until a specific application is executed in a power off state as proposed to solve the above-mentioned problems.

FIG. 3 is a diagram illustrating a data structure commonly used in each case of booting in a general function mode and a specific function mode.

According to a feature of the present invention for achieving the object of the present invention as described above, booting into a specific function mode to provide a minimum environment for performing a specific function of the computer system, perform all the general functions of the computer system A booting method of a computer system having a boot into a normal function mode which can be performed includes: a booting step by the Basic Input Output System (BIOS); The booting step by an operating system (OS) and the booting step by the OS are booted to provide a minimum environment of a computer system for performing the specific function when the booting step by the OS is set to boot in a specific function mode.

(Example)

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

The novel computer system booting method of the present invention has a booting of a specific function mode for performing a specified function and a booting of a general function mode to function as a general computer system. When booted in a mode to perform a specific function, it has a lower latency than booting in a normal function mode.

In booting in a mode to perform a particular function, the computer system boots to provide a minimal environment for that particular function. In the boot mode to the normal function mode, the computer system is booted so that all the functions of the computer system can be used normally.

For example, a computer system with a communication modem that wakes up the computer system in response to a ring signal received over a telephone line provides only a minimal environment to perform an auto answer function when a ring signal is received in a power off state. The computer system will boot up. That is, in an environment in which the answering machine is performed, various functions such as a mouse function, a print function, a screen output function, and a graphic user interface are not necessarily required. Therefore, the OS needs to be run to provide only the minimum environment to perform the auto answer function. In this case, the latency is lower than that of the general booting process.

2 is a flowchart sequentially illustrating a booting process of a home computer system according to a preferred embodiment of the present invention. Referring to FIG. 2, when the computer system is powered on at step S100, a booting process by the BIOS is first performed at step S110. When the booting process by the BIOS is completed, the booting process by the OS is started. At this time, in step S120, it is determined whether the booting is performed in a specific function mode.

If it is set to boot in a specific function mode, the process proceeds to step S130 to boot to a specific function mode. When booting is completed, the computer system operates with the specified function in step S140. If it is set to operate in the normal function mode, the normal function mode boot is performed in step S150. When booting is completed, the computer system operates as a normal function in step S160.

After the use of the computer system is completed, it is determined whether to change the boot mode setting in step S170 in the process of powering off the computer system. This process is made by the user. If the user selects to change the boot mode setting, the boot mode is changed in step S180. In step S190, the computer system is powered off.

As such, the computer system has two different boot modes but the data generated in each different environment is shared with each other. As shown in FIG. 3, a computer system 100 having a common data structure 300 and requested to perform a particular function and a computer system 200 booted in a normal boot mode have a common data structure 300. Will share data. The common data structure 300 is allocated and used in a predetermined area of a hard disk drive of a computer system.

The boot mode can be set by the user using a specific utility that operates in each mode. For example, the current Windows operating system can change the boot mode by changing the configuration of the system file MSDOS.SYS. In other words, by setting BootGUI = 1 in the [OPTIONS] section of the MSDOS.SYS file, you can configure booting into the graphical user interface environment. You can set BootGUI = 0 to boot into the text mode environment. Booting in text mode has lower latency than booting in a graphical user interface environment.

In the above, the configuration and operation of the circuit according to the present invention are shown in accordance with the above description and drawings, but this is merely described, for example, and various changes and modifications are possible without departing from the spirit of the present invention. .

According to the present invention as described above, when the computer system is booted to perform a specific function, the computer system is booted to have a low latency, so that the specific function can be performed immediately.
