Benefits of technology

[0016]According to the quick booting method of the present invention, after ASCII statements listed in an initial device configuration file and an automatic batch file are executed, a boot configuration information that is resident in a memory, i.e., the status of devic...

Problems solved by technology

Therefore, in case where there are a lot of ASCII statements in CONFIG.SYS and AUTOEXEC.BAT, the quick boot of the conventional art is not effective to reduction of the boot time.
If memory size ...

Embodiment Construction

[0026]The preferred embodiments of the present invention will be described below in detail referring to the accompanying drawings.

[0027]FIG. 3 is a flowchart of the quick boot process in an IBM personal computer system according to an embodiment of the present invention. The flow proceeds to step S21, in which a POST operation is performed when a computer system is powered on or a reset button is pressed. A normal boot process of an operating system, e.g., Windows95 is then executed (S22). Next, a boot configuration information, i.e., the contents of memory and the status of the attached devices that was created and has been resident in a memory since execution of the POST operation is saved to a disk (S23). A RAM-resident program is called by a software interrupt (INT in general) in modified ROM BIOS codes so as to save the boot configuration information into a disk for future boots. Since the, when a reboot is requested (S24), the POST operation is performed and then the saved boo...

Abstract

A method for quickly booting a personal computer system using boot configuration information on memory and the attached devices that was created and saved in a hard disk at the preceding boot process. The method for a quick boot process includes the steps of performing a power-on self test POST) operation when a personal computer system is powered on or a reset button is pressed; performing a normal boot process after the POST operation; saving the contents of memory and the status of the attached devices to a hard disk; checking if a reboot is requested; restoring the saved boot configuration information from the hard disk, after POST is completed during the reboot process; checking whether or not an initial device configuration file and/or an automatic batch file were changed; and executing commands in the two files and saving a newly created boot configuration information to the hard disk for future boot. The personal computer system, may reboot quickly because of omission of execution of the initial device configuration filed and the automatic batch file.

Description

BACKGROUND OF THE INVENTION[0001]1. Field of the Invention[0002]The present invention relates to a method of and apparatus for booting a personal computer system and, more particularly, for quickly booting a computer system, in which a boot configuration information is created and saved in a disk for future boot, and the saved boot configuration information is reused upon the request of the subsequent boot.[0003]2. Description of the Related Art[0004]FIG. 1 shows a block diagram of the system architecture for a conventional personal computer system, comprising a central processing unit (CPU) 1; a read only memory (ROM) 2 for permanent storage of basic input output system (BIOS) and the initial states of internal devices, a random access memory (RAM) 3 for temporary storage of information; a micro computer (MICOM) 4 for controlling peripheral devices such as a keyboard input device, a mouse input device, and a power supply 7; a hard disk (HDD) 8 for providing a secondary information ...
