Selective boot method of computer system by detecting CD-ROM disk drive type

The present invention relates to a selective booting method of a computer system by detecting a CD-ROM disk drive type, and more particularly, after determining the type of CD-ROM mounted in the computer system and loading a CD-ROM drive file corresponding thereto into a memory of the computer system. To boot a computer system.

In computer manufacturers, since the number of parts supplied for manufacturing a computer varies depending on the supply and demand of parts, it is very difficult to use only one company's parts. In particular, in the case of CD-ROM disk drives, rapid demand is created due to the expansion of multimedia functions, and it is very difficult to supply parts. Therefore, various types of CD-ROM disk drives are used in one computer model. However, if the CD-ROM disk drive changes, the drive program (also called a device driver) that can drive it changes, so the computer manufacturer has to replace the drive files on the CD-ROM disk drive with a different one each time the computer is booting. And the resulting loss of human physical property. Furthermore, with the adoption of Windows 95, the computer operating system is stored on the CD-ROM and provided to the consumer. When the type of CD-ROM drive attached to the computer changes, the CD-ROM drive file corresponding to the CD-ROM drive must be provided to the consumer. It has been pointed out as a very unreasonable element of management. In addition, in order to recover a damaged hard disk of a computer system, in addition to restoring the general data on the hard disk, the type of CD-ROM installed in the user's computer is identified, and a corresponding drive program is selected. It must be resident in memory. However, the general user has not been able to identify the type of CD-ROM disk drive installed in his computer or easily select a driving program suitable for it.

Accordingly, an object of the present invention is to provide a method of reading a type of CD-ROM mounted on a computer system and booting a CD-ROM drive file corresponding to the CD-ROM drive file in a memory of the computer system when the computer system is booted.

Selective boot method of a computer system by detecting a CD-ROM disk drive type of the present invention for achieving the above object is

In the boot method applied to a computer system having a hard disk and a CD-ROM disk drive,

(a) sending an ATAPI IDENTIFY DRIVE command to the IDE controller;

(b) searching for and reading the type of CD-ROM recorded in the memory built into the CD-ROM disk drive; And

(c) selecting a driving file for driving the CD-ROM according to the read CD-ROM type; and

(d) residing in the memory the drive file selected by the above process.

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

1 is an operation flowchart of a hard disk recovery program having a selective booting function of a computer system by detecting a CD-ROM disk drive type of the present invention, and FIG. 2 is a selective booting method of a computer system by detecting a CD-ROM disk drive type of the present invention. Shows a flow chart.

The computer system booting method of the present invention can be applied to a computer system having a hard disk and a CD-ROM disk drive. In such computer systems, the port where the CD-ROM disk drive is mounted can be found through the CMOS setup information that is run when the computer boots. It is assumed that through this CMOS setup information, the computer system knows that the hard disk is attached to the primary master and the CD-ROM disk drive secondary master. The hard disk recovery program implementing the computer system booting method of the present invention recognizes the port where the CD-ROM disk drive is located and then operates when the computer boots. The necessity of recognizing the type of the CD-ROM is to boot the system through another medium such as a separate floppy disk in case the hard disk of the computer system is damaged. Thus, the computer system booting method of the present invention recovers the damaged hard disk. It can be useful for programs. Preferably, the recovery program is inserted into an environment file (CONFIG. SYS) of a bootable diskette or a bootable CD-ROM disk for booting a computer to operate when the computer system is booted.

As shown in FIG. 1, the hard disk recovery program enters the CD-ROM disk drive detection step of the present invention by selecting the option / O or / 4. The difference between these two options is that / 4 does not output a message about the result of the program to the user, and / 0 causes the user to output a message about the result of the operation. Upon entering the CD-ROM detection step, as shown in FIG. 2, after the CD-ROM disk drive is found out through the CMOS setup information which is executed at the time of booting of the computer (S0), the recovery program is executed. The ATAPI IDENTIFY DRIVE command is sent to the IDE controller controlling the CD-ROM disk drive (S1). Here, an integrated drive electronics (IDE) system is a disk or CD-ROM disk that is used if the computer system has only a controller for controlling these programs by installing a memory containing a disk drive control program on the printed circuit board of the disk drive. Regardless of the type of drive, the installed disk drive or CD-ROM disk drive can be controlled. By adopting this method, the user has the advantage of being able to drive various disk drives or CD-ROM disk drives supporting ID format using only a general-purpose controller. In addition, ATAPI is a standard for the interface of the CD-ROM among the devices to which the ID is applied. Therefore, if the above mentioned ATP ID drive command (0A1H) is input to the IDE controller, the ID controller reads the information recorded in the memory in the CD-ROM disk drive and outputs this value. (S2). The information about the manufacturer of the CD-ROM disk drive to be inspected is recorded in a location between 54 and 64 bytes of the 512-byte information thus obtained, and this information is compared with the information contained in the CD-ROM disk drive detection program. The type and the mounted CD-ROM are determined to which company the product is (S3). The determination process is performed by having a list of information on the model name of each CD-ROM disk drive in the recovery program, and recording the name of the drive file and the manufacturer for each model name. This information may be stored in a separate file for additional convenience. Therefore, in case of using a new CD-ROM disk drive, it is necessary to input the information to the recovery program to determine the type of CD-ROM mounted. In this case, information about the new CD-ROM disk drive should be added to the program. Next, information about the type of the CD-ROM may be informed to the user through a monitor or the like (S4).

When the type of the CD-ROM is determined as described above, the recovery program selects a drive file suitable for the type of the CD-ROM drive read (S5). The selected drive file resides in a memory to boot a computer system or to make a system disk by copying it to a hard disk or a separate floppy disk (S6).

In FIG. 1, when the user selects option / 5, information about the manufacturer of the system recorded at the F000: 0000 position of the ROM BIOS of the computer system is recognized to determine whether the computer currently running the program is a specific company. This option is to determine the value recorded in the ROM of the computer system so that it operates only on the computer system measured by the present program. Option / 1 is used to repair a damaged hard disk by using the method of the present invention. When the user selects this option, the user deletes all contents of the damaged hard disk, reinstalls a program, or creates a startup disk. I can do it. Option / 2 is to print a message to determine whether the system is rebooted after recovering the hard disk, and option / 3 is to output a message to terminate the program.

By setting the option of such a program appropriately according to the use of the program to make it a batch file or allowing the user to set it, the CD ROM drive type detection result of the present invention can be variously applied. That is, if the recovery program is operated when the computer system is booted with the option of / 0 or / 4 of the present invention, and a drive file corresponding to the detected CD-ROM type is loaded into RAM, it is irrelevant to the CD-ROM disk drive type. The computer system can be booted easily, and a system disk can be easily created using the drive file. In addition, other options may be used to allow the user to check the operation of the program or use the program to recover a damaged hard disk using the / 1 option. In other words, if you place options / 1 and options / 0 or / 4 in the proper order, after deleting all the files in the currently damaged hard disk, the installed CD-ROM disk drive will be automatically recognized and the corresponding CD-ROM disk drive will be automatically detected. You can also recover a damaged hard disk by copying the drive file to the hard disk.

In this case, when the program is mounted on a boot diskette or a bootable CD-ROM disk, the type of CD-ROM drive may be informed to the consumer, and the CD-ROM drive drive file selected accordingly may be loaded into the memory of the computer system. Therefore, a single diskette or bootable CD-ROM disk drive, regardless of CD-ROM manufacturer, can automatically recognize and drive CD-ROM disk drives from multiple manufacturers.

Because of this, first, you do not have to create a diskette or bootable CD-ROM with a specific drive file for the CD-ROM disk drive.

Secondly, regardless of the type of CD-ROM disk drive installed in the computer system, a large amount of programs with CD-ROM drive files can be copied to the consumer to reduce manufacturing costs.

Thirdly, even if the user does not know the type of CD-ROM disk drive installed in the computer, the CD-ROM can be correctly driven by automatically recognizing it.

Fourth, since the above program can be loaded in the CD-ROM disk, a CD-ROM disk drive of several companies can be driven by a single CD-ROM disk, and a CD-ROM for restoring a hard disk can be easily recovered if the hard disk is destroyed. I can make it.
