Abstract

PROBLEM TO BE SOLVED: To remotely reload a basic input/output system(BIOS) program without interventing any operator. SOLUTION: A client computer 21 is composed of a non-volatile storage device 31 for storing the working state or reloading processing state of computer and a mass storage device 41 for preserving BIOS data and a reloading program sent from a host computer 1 through a network. Further, this mass storage device 41 is composed of an operation OS storage part 61 for storing a usually operated multitask OS, a data storage part 62 for storing these data and program, a reloading OS storage part 63 for storing an OS to execute a reloading tool, and an OS data storage part 64 for preserving a current operating state.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001] 1. Field of the Invention [0002] The present invention relates to a system for automatically rewriting BIOS programs of a plurality of computers connected to a network.

[0001]

2. Description of the Related Art Conventionally, this type of BIOS (Basic
The Input Output System (Rewrite) method is a method for rewriting at the next start-up in order to update the BIOS program without stopping the system.

For example, Japanese Patent Application Laid-Open No. Hei 8-16408 discloses that an updating BIOS program is input to an updating program memory and written while the OS (Operating System) program is running, and the BIOS program is written at power-on or at reset. A configuration in which the data is updated by copying to a memory area of a main memory is described. Also, Japanese Patent Application Laid-Open No. 8-44571 discloses that
A technique is described in which a parameter value for hardware control included in a BIOS program is rewritten by recognizing a hardware configuration and updated at power-on.

[0003]

A first problem is that a utility program for updating a BIOS program even when remotely operated from an external computer (maintenance computer or remote maintenance computer) is started by an operator. I have to.

[0004] The reason is that when rewriting is performed remotely, a utility program cannot be automatically started.

[0005] The second problem is that a BIOS memory for writing a BIOS program or an update program must be added.

The reason is that when data is rewritten at the time of startup, data written in the BIOS memory is copied to a memory area.

An object of the present invention is to provide a BIOS rewriting method which allows a client-side operator to update a BIOS program of a client computer by remote operation from an external computer (maintenance computer or remote maintenance computer) without doing anything. To provide.

[0008]

According to the BIOS rewriting method of the present invention, a client computer is used by switching between an operating OS and a rewriting OS, and a BIOS program transferred from a host computer is used by the BIOS rewriting program. Rewrite.

[0009]

Next, a first embodiment of the present invention will be described in detail with reference to the drawings.

Referring to FIG. 1, in a first embodiment of the present invention, a BIOS rewrite instruction is issued,
A host computer 1 capable of simultaneously transferring OS data to a plurality of computers and a client computer 21 for which BIOS rewriting is performed are connected via a network. Network ISDN
, And a plurality of client computers 21 may be connected. In the present embodiment, a case will be described in which the BIOS of one client computer 21 is rewritten by the BIOS data transferred from the host computer 1 via a public line.

First, the detailed configuration of the client computer 21 will be described.

FIG. 2 is a block diagram showing a configuration of the client computer 21 according to the first embodiment. In FIG. 2, the client computer 21
A nonvolatile storage device 31 for storing the operating state of the computer and a rewriting process state, and a large-capacity storage device 41 for storing BIOS data and a rewriting program sent from the host computer 1 via a network. Have been. Furthermore, the mass storage device 4
Reference numeral 1 denotes an operating OS storage unit 61 that stores a multitask OS that is normally used, a data storage unit 62 that stores the BIOS data and the rewriting program, and a rewriting OS that stores an OS that controls the execution of the rewriting program. It comprises a storage section 63 and an OS data storage section 64 for storing operation state information indicating the current operation state. The operating OS storage unit 61 and the rewriting OS storage unit 63 monitor the current state of the computer over time, determine a rewriting processing method, and store a rewriting processing program 51 for performing a reboot (restart).

Next, the operation of the client computer 21 will be described with reference to the drawings.

Referring to FIG. 3, the host computer 1
The rewriting instruction is issued by the client computer 2 operating on the multitask OS in the operating OS storage unit 61.
1 and the flag 311 of the non-volatile storage device 31 is changed to a rewrite flag (step S1). Next, BI
The OS data is transferred to the data storage unit 62 of the mass storage device 41 (Step S2). Next, the rewrite processing program 51 monitors the flag 311 of the nonvolatile storage device 31 over time, and checks whether the flag 311 has been changed to a rewrite flag (step S3). If it has been changed to the rewrite flag, the flag 312 of the non-volatile storage device 31
To the rewrite processing OS flag (step S
4). Further, the rewriting processing program 51 monitors the operation state, detects a time when the operator hardly uses the time (step S5), and sets the OS loaded on the memory.
Is stored in the OS data storage unit 64 (step S
6) Reboot (step S7). Then PO
The ST starts to operate, and the flag 312 of the nonvolatile storage device 31
To determine the flag (step S8), and the rewriting OS for performing the rewriting process starts up.

The BIOS is rewritten using a rewriting program.
Rewrite with the transferred BIOS data (step S1
0). The rewrite processing program 51 changes the flag 312 of the nonvolatile storage device 31 to the normal operation OS flag,
Further, the flag 311 is cleared and the system is rebooted. Thereafter, when the POST starts moving, a flag is determined, the OS which is normally operated is started, and the OS data storage unit 6 is activated.
4 to return to the previous operation state based on the OS data saved in the previous operation state.

In this embodiment, since the flag operation is performed remotely, the usage status of the operator is monitored by the monitoring function of the operating OS, and the BIOS is automatically rebooted to rewrite the BIOS, the operator does not need to do anything. Latest BIOS
Can be changed to

Further, since the tool and the data are transferred to the data storage unit, it is possible to cope with rewriting other rewritable devices regardless of the BIOS.

Next, a second embodiment of the present invention will be described with reference to the drawings.

Referring to FIG. 4, the BIOS revision 313 is stored in the nonvolatile storage device 31 in the first embodiment.
Has been added. Before sending a rewrite instruction from the host computer 1 to the client computer 21, the BIOS
The revision 313 is checked to determine whether it is the latest. If it is the latest, the transfer of the BIOS data and the BIOS rewrite program is not performed, and the rewrite is not performed. If it is not the latest, the operation is the same as that of the first embodiment.

In this embodiment, it is possible to perform fine rewriting management such as suppressing unnecessary data transfer and rewriting.

[0021]

The first effect is that the operator on the client side can change to the latest BIOS without any particular operation.

The reason is that the usage status of the operator is monitored by the monitoring function of the operating OS on the client side, and the rewriting is performed by automatically rebooting.

The second effect is that it is possible to perform detailed rewriting management such that the latest BIOS is not rewritten.

The reason is that the rewrite flag and the BIO
This is because the S revision and the like are stored in the non-volatile storage device, and rewriting is controlled by checking the S revision.

The third effect can be applied to the case where other rewritable devices are rewritten regardless of the BIOS.

The reason is that the data and its rewriting program are transferred to the mass storage device and the program is executed.
