Abstract

PROBLEM TO BE SOLVED: To provide a storage device initializing method by which an execution time of an initialization program of a hard disk can be shortened. SOLUTION: In this initializing method, not the routine of the original hard disk BIOS but an independent interruption routine 7 for processing a verify command is started by re-writing an interruption vector of a hard disk BIOS in BIOS 2 by vector processing of the hard disk BIOS, and successively, the initializing program 4 is executed, and a verify command issued from the initializing program 4 is nullified by the independent interruption routine 7 for processing verify command. Thus, since the verify command is not executed, an execution time of the initializing program 4 is substantially shortened compared with a conventional one.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for initializing a storage device, and more particularly to a method for initializing a hard disk built in a computer.

[0002]

2. Description of the Related Art For products that are shipped with an operation system (OS) or an application program installed in advance in a hard disk device built into a computer main body, development is performed using a manufacturing copy system for bringing the product to a shipping state. In this manufacturing copy system, a file of an OS or an application program is stored in a floppy disk medium or a CD-ROM medium, and a built-in hard disk is initialized by program control, and then the file is copied.

[0003]

However, the initialization of the internal hard disk in the above-mentioned conventional production copy system is performed by an initialization program. However, a verify command issued from the initialization program is used for the initialization time. Most of the time is spent, and the initialization process runs each time the hard disk is installed from the production copy system. Therefore, there is a problem that it takes a lot of man-hours to develop and evaluate the production copy system.

[0004] The present invention has been made in view of the above points,
An object of the present invention is to provide a method of initializing a storage device that can reduce the execution time of an initialization program for a hard disk.

[0005]

In order to achieve the above object, the present invention provides an initialization program which issues a command to a BIOS which can directly give an instruction to a storage device to be initialized. In the initialization method for initializing the BIOS, before executing the initialization program, the interrupt vector of the BIOS is rewritten so that the own interrupt routine is started instead of the original processing of the BIOS, and the initialization is executed by executing the initialization program. From the conversion program to BIO
When a command is issued to S, its own interrupt routine is started to determine whether the type of the issued command is a predetermined type that can be omitted. If a command of the predetermined type is issued, the command is invalidated. That is, when a command of a type other than the predetermined type is issued, the original processing of the BIOS is executed.

According to the present invention, when a command of a predetermined type is issued from the initialization program to the BIOS by execution of the initialization program, the command is invalidated by its own interrupt routine. The command of the predetermined type can be prevented from being executed.

Here, the storage device is a hard disk, and the command of a predetermined type may be a verify command. In this case, the verify command is not executed when the hard disk is initialized. Can be.

[0008]

Next, an embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a block diagram showing an embodiment of an apparatus to which a hard disk initialization method according to the present invention is applied. In FIG. 1, a hard disk 1 is a hard disk to be initialized. The BIOS 2 is a basic input / output system that transmits commands directly to the hard disk 1. The OS 3 is basic software that operates on the BIOS 2. The initialization program 4 initializes the hard disk 1. The verify command skipping program 5 is a hard disk BIOS that forms a main part of the present invention.
And a command change interrupt routine 7 for verify command processing.

The vector change processing 6 of the hard disk BIOS enables a verify command processing interrupt routine 7. Also, the verify command processing interrupt routine 7 is executed when the initialization program 4
It operates when issuing a command to the IOS (this is one type of BIOS2), does nothing for a verify command, and passes the process to the BIOS2 for other than a verify command.

Next, the operation of this embodiment will be described. Before executing the initialization program 4, first, the verify command skipping program 5 is executed. When the operation of the verify command skipping program 5 starts, the vector change processing 6 of the hard disk BIOS operates.

FIG. 2 is a flowchart showing the processing operation of the vector change processing 6 of the hard disk BIOS.
As shown in FIG. 2, when the hard disk BIOS vector change processing 6 starts operation, for example, the jump destination memory address stored in the hard disk BIOS entry of the interrupt vector table of the memory is changed by acquiring the vector interrupt vector of the hard disk BIOS. After acquiring (step 11) and storing the acquired memory address in a known internal memory (not shown in FIG. 1) or the like, the vector replacement is executed in a verify command processing interrupt routine (step 12). Then, the vector change processing of the hard disk BIOS ends. In the vector replacement process to the verify command processing interrupt routine in step 12, the hard disk B (not shown)
The jump address to the verify command processing interrupt routine is stored in the entry of the interrupt vector table in which the jump memory address to the IOS has been stored.

Next, an initialization program 4 is executed.
Initialization program 4 is the hard disk B in BIOS2
When various commands such as a read / write command and a verify command are issued to the IOS, first, a verify command processing interrupt routine 7 is called.

FIG. 3 is a flowchart showing an example of the verify command processing interrupt routine 7. This verify command processing interrupt routine 7 determines whether or not the command to the hard disk BIOS issued by the initialization program 4 is a verify command (step 21), and ends the process without doing anything if it is a verify command. .

On the other hand, if the command issued to the hard disk BIOS by the initialization program 4 is a command other than the verify command, the process proceeds from step 21 to step 22 to obtain the interrupt vector of the hard disk BIOS in step 11 described above. Based on the jump destination memory address to the hard disk BIOS stored in the internal memory,
The routine of S is called, and the process is passed to BIOS2. The above operation is performed when the initialization program 4
The processing is continued until the processing of all commands issued to the OS ends.

As described above, in this embodiment, the interrupt vector of the hard disk BIOS is rewritten in advance,
Instead of the original hard disk BIOS routine, an independent interrupt routine for verify command processing is activated, and subsequently, the initialization program 4 is executed. Since the invalidation is performed by the interrupt routine, the verify command is not executed, so that the execution time of the initialization program 4 can be significantly reduced as compared with the related art.

The present invention is not limited to the above embodiment. For example, in the above embodiment, the command to be invalidated is limited to the verify command, but it can be omitted for speeding up. If there is a command, other commands may be invalidated. The device to be initialized is an auxiliary storage device other than a hard disk (such as a magneto-optical disk storage device or a floppy disk drive).
Is also applicable.

[0017]

As described above, according to the present invention,
B from the initialization program by executing the initialization program
When a command of a predetermined type is issued to the IOS, the command is invalidated by its own interrupt routine so that the command of the predetermined type is not executed at the time of initialization. Can be shortened. In particular, the present invention is applied to a hard disk as a storage device, and as a command of a predetermined type,
When the present invention is applied to a verify command, according to the present invention, a verify command that spends most of the initialization time can be invalidated so as not to be executed. Can be shortened.
