[0001]

The present invention relates to a computer system.
Especially as an external storage medium for computer equipment.
Computer system using a removable storage medium
You. In recent years, an optical disk using the magneto-optical effect has been attracting attention as a portable and rewritable large-capacity storage medium. It is capable of storing a large capacity of 128 Mbytes on a single optical disk and has a small and portable characteristic of 3.5 inches, and can store and carry various information such as an OS (operating system) and application programs. it can. Further, there is an IC card or the like as a replaceable storage medium, which is smaller as a portable medium as described above. Therefore, it is desired that a single storage medium such as an optical disk can be appropriately operated on computer systems of different models.

Accordingly, it is desired that a single storage medium such as an optical disk can be appropriately operated on computer systems of different models.

[0003]

2. Description of the Related Art Conventionally, computer equipment represented by a personal computer (hereinafter, referred to as a personal computer) has been designed on the premise of a magnetic disk device which is a fixed external storage device. Therefore, once the correspondence between the device configuration of the external storage device and the logical drive configuration has been determined, there has been no change. Such a correspondence table between the physical drive configuration and the logical drive configuration is recorded, for example, in a battery-backup-type semiconductor memory in a computer device.

[0004] Further, since the OS and application programs mounted on such a fixed magnetic disk always operate under the same environment, once a parameter is determined, it is generally not changed. . Therefore, for example, even if data created in one computer system is moved to a floppy disk and operated in another computer system, it cannot be used unless an application program corresponding to another computer system is installed, and Even if the application program is installed, it is necessary to reconfigure the environment such as the logical drive number.

FIG. 46 is a block diagram of a conventional optical disk and a computer system, and FIG. 47 is an explanatory diagram of a table on the semiconductor memory of FIG.

In FIG. 46, a personal computer 11 as a computer device has a SCSI (Small Computer Systems Incorporated).
An optical disk device 13 is connected through a terface 12. The optical disk device 13 drives an optical disk 14. These systems are designated as A, and a plurality of systems (for example, A and B) are configured.

The personal computer 11 has a disk 21, a boot R
An OM (Read Only Memory) 22 and a semiconductor memory 23 for storing parameters are provided.

The boot ROM 22 has a reading means P7 for reading a correspondence table between a physical drive and a logical drive on the semiconductor memory 23, and a boot program B2 for correspondence means P3 between a physical drive and a logical drive.

The semiconductor memory 23 is of a battery backup type, and stores a physical drive / logical drive correspondence table T2 and a boot SCSI-ID table T3. This table T3 is for specifying the startup SCSI of a predetermined number of optical disk devices 13 connected to the personal computer 11.

The optical disk 14 has an OS (Oprati
On System) A start program P10, an OS (P11), a program P5 such as an application, etc. are recorded, and a presentation tool P8, screen data P9, and a test driver P12 are recorded here.

For example, it is a tool for creating a plurality of screens P9, recording them on an optical disk, and calling the data of each screen from the optical disk 14a to the personal computer 11 and displaying the data on the display 21. Using the presentation tool P8, five screens P9 were created and stored on the optical disk 14 set in the optical disk device 13.

Here, the semiconductor memory 23 of the personal computer 11
For example, in the system A, the tables T2 and T3 recorded above are stored in the table T as shown in FIG.
2 stores a correspondence table between the SCSI-IDs (0, 1,...) Of the physical drives and the logical drive names (for example, D, E, F, and G), and a SCSI-ID number to be started (FIG. 47) in a table T3. In (A), 1) is recorded. SCSI-
Two logical drives are allocated to the drive with ID = 1, and are E and F, respectively. In a different system B, as shown in FIG.
A correspondence table between SCSI-ID numbers and logical drive names of physical drives different from those described above is recorded, and SCSI-ID = 2 is recorded in table T3. The tables T2 and T3 can be rewritten by the user.

FIG. 48 shows an operation flow at the time of a presentation tool test in the conventional example. First, in the system A, the optical disk device 13 is powered on.
Then, the optical disk 14 is inserted, and the personal computer 11 is powered on (steps (ST) 1 to 3).

When the personal computer 11 is powered on, the boot program B2 in the boot ROM 22 starts operating (ST4). Therefore, first, the correspondence table T2 in the semiconductor memory 23 is read, and the SCSI-ID table T3 is read (ST5). The reason why such an operation is performed before the OS is started is that the OS accesses the external storage device using a logical drive name, so that the correspondence between the physical drive configuration and the logical drive configuration is determined before the OS is started. This is because it is necessary.

Then, as shown in FIG. 47A, it recognizes that the startup SCSI-ID is 1 and recognizes that its logical drive name is E (ST6).

Next, the OS recorded on the optical disc 14
The boot program P10 is read, and the control is passed to this program (ST7).
11) is read and activated (ST8). At this time, correspondence between the logical drive and the physical drive is required.

Subsequently, the device drive P12 (software program of a group of drivers for controlling external devices) is read from the logical drive E (in this case, the optical disk 14a) (ST9). The read destination drive name is stored as a parameter in the OS as a logical drive name, and in this example, the parameter is “E drive”. Then, the OS starts up (ST10). Subsequently, the presentation tool P8 is read from the optical disk 14 (ST11), and the operation is started (ST12). And
The screen data P9 is read from the logical drive E (optical disk 14) (ST13), and the screen data P9 is displayed on the display 21 (ST14). The process ends when five images are displayed (ST15).

After the presentation test ends, the program P5 such as an application is read and executed.

Meanwhile, in another system B having the same configuration, the contents of the correspondence table T2 between the physical drive and the logical drive are not fixed so as to be rewritable in consideration of use by a large number of users. 47 (B), and SCSI-ID = 2.

In this case, since the presentation tool 18 written on the optical disc 14 does not operate, it is necessary to adjust the operating environment of the personal computer 11.
Therefore, the SCSI-ID of the optical disk device 13 is set to 1 and the tables T2 and T3 in the semiconductor memory 23 are stored in the table shown in FIG.
7 (A) to make the operating environment of the system B the same as the operating environment of the system A.

In this state, by inserting the optical disk 14 into the optical disk device 13 and turning on the power, a presentation tool test as shown in FIG. 48 can be performed.

That is, the OS on the single optical disk 14
Even if (P11) and the presentation program P8 are stored, in order to operate the screen data P9 created on a system with a different environment at another presentation site, the correspondence table T2 between the physical drive and the logical drive must be set. It has to be changed manually and requires a complicated operation.

Next, a program P such as an application
5 will be described. An example in which a spreadsheet is calculated by an application program of the program P5 in this case will be described.

FIG. 49 is an explanatory diagram of the recorded contents of the optical disk, and FIG. 50 is an explanatory diagram of the contents of the operating environment information on the semiconductor memory. In FIG. 49, although not shown in FIG. 46, the optical disc 14 generally has an IPL (Initial Program).
(ram Loader: initial program reading means) P1 is recorded, and the OS boot program P1 is recorded in the same manner as in FIG.
0, OSP11, and application program P5
Is recorded.

In the system A, for example, the logical drive name (E) of the optical disk and the RAM (Rand) provided in the personal computer 11 are stored in the semiconductor memory 23 in the personal computer 11.
om Access Memory) Logical drive name of the disk (F),
The extended memory capacity for the system (1 MB) and the RAM disk capacity for the application (1 MB) are recorded. In the system B, for example, the logical drive name of an optical disk (C), the logical drive name of a RAM disk (D),
The system expansion memory capacity (4 MB) and the application RAM disk capacity (0 MB) are recorded.

FIG. 51 shows an operation flow of the application program. In FIG. 51, first, in the system A, the optical disk 14
(ST21), and turn on the power of the personal computer 11.
The state is set (ST22). Thereby, the boot ROM 2
2 starts (ST23), loads and executes the personal computer IPL (P1) from the optical disk 14, and transfers control to it (ST24).

Therefore, first, the operating environment information (FIG. 50A) of the tables T2 and T3 in the semiconductor memory 23 is read. This operation is performed before the OS is started for the same reason as described above.

Then, based on the read operating environment information, the OS starting program P10 is read, and the personal computer OS (P11) is started (ST25), and control is passed to this.

Here, as shown in FIG. 50A, the logical drive name of the optical disk device 13 is "E drive", and the logical drive name of the application RAM drive secured on the extension memory is "F". Drive ". The spreadsheet application program (spreadsheet software) P5 has logical drives E and F as parameters in the program, and accesses the optical disk 14 and the RAM disk using these logical drive names.

Then, the spreadsheet software P5 is started (ST
26), work is performed based on this (ST27).

On the other hand, when the spreadsheet is calculated for another system B using the same optical disk 14, the operating environment information of the system A differs from that of the system B (FIG. 50A,
(B)), the spreadsheet software P5 does not operate as it is. Therefore, as described with reference to FIG. 46, by rewriting the operating environment of the system B in the same manner as the system A, the system B performs work using the same optical disk 14.

FIG. 52 is a block diagram showing another conventional computer system. In FIG. 52, system A
In both the system B and the system B, a hard disk device 15 and a floppy disk device 16 are connected to the personal computers 11a and 11b, and the floppy disk device 16 is a floppy disk 16 as a replaceable storage medium.

In this case, the hard disk in the hard disk device 15 of the system A records word processor (hereinafter referred to as word processor) software P13 for the A personal computer, and the hard disk in the hard disk device 15 of the system B stores the B personal computer. The word processing software P14 (the function of the word processing software is the same as P13) is recorded. The created document data P15 is recorded on the floppy disk 16a.

Therefore, in the system A, a document is created by operating the A personal computer word processing software P13 recorded on the hard disk in the hard disk device 15,
The data P15 is created on the hard disk. The data P15 is transferred to the floppy disk 16a by the floppy disk device 16.

On the other hand, in the system B, the hard disk drive 15 is started up, and the word processing software
14 is operated. Therefore, the floppy disk drive 16
Document data P15 in the floppy disk 16a via
Is transferred to the hard disk drive 15 to continue the document creation in the same manner.

The word processing software can be assigned to a function key to realize a function by one touch. However, the key assignment can be changed. Therefore, when the key assignment is changed in the system A and used in the system B, the key assignment needs to be changed again.

That is, when the same work is performed in different systems, it is necessary to transfer the document in the hard disk to the floppy disk 16a once, and it is necessary to change the key assignment or the like for each system.

FIG. 53 is a block diagram showing a modification of the computer system shown in FIG. In FIG. 53, the same A personal computer 11a is used for both the systems A and B. The A personal computer 11a of the system A has an extended memory of 8 MB, and the A personal computer 11a of the system B has an extended memory of 1 MB. Things. Also, an optical disk device 13 is connected together instead of the floppy disk device 16, and the optical disk 14 recorded from the word processing software P13 is shared.

First, when the document data P15 is created by the word processing software P13 in the system A, it is assumed that the word processing software P13 requires an extended memory of 2 MB. When the optical disk 14 is used in the system B, the word processor software P13 of the optical disk 14 cannot be used due to the difference in the extension memory. Therefore, the same word processing software, which is a function limiting board word processing software P16 that does not require an extended memory, is used as the hard disk drive 1
5, the optical disk 14 is used.

As described above, even in the case of personal computers of the same model, if the operating environment is different due to a difference in the extension memory or the like, the word processing software to be used must be changed.

At present, there are various types of OSs of personal computers, but these systems are installed on a hard disk and the personal computer is started from there. OS
However, different PC models cannot be started due to differences in hardware. The hard disk can be used by dividing the partition into several sections depending on the OS. In other words, it can be divided into logical drives and treated as if there were different types of hard disks. This is generally called a multi-compartment. in this case,
Different systems can be installed in each partition, and several OSs can be used on one personal computer.

However, since the hard disk is not portable, the system was not used in another place. Also, it is not possible to connect the disk to a different type of personal computer and start up. This is because if the model is different, even if the same type of OS is used, there is a hardware-dependent part, and the operation stops at that part.

Therefore, it is possible to use an optical disk (magneto-optical disk) having a larger capacity than a floppy disk and to be portable, and it has become possible to install several systems on one optical disk and start up with different models. I have.

[0044]

However, as described above, when a plurality of users try to operate one computer device such as a personal computer with an optical disk possessed by each user, a physical device is operated by input means such as a keyboard each time. The operating environment of the computer must be adjusted by resetting the correspondence between the dynamic drive configuration and the logical drive configuration,
There is a problem that complicated operations are required.

When data of the same type is created in different computer systems, a program corresponding to the computer system must be installed, and even if it is installed, the data must be transferred to a floppy disk once. . On the other hand, when a software program is customized in a predetermined computer system, there is a problem that similar software programs must be customized again in other computer systems.

In this case, even if the optical disk device 13 is connected, even if the contents of the conventional hard disk are simply transferred to the optical disk 14 and are to be operated on another computer system, the operation environment is different. ,
There is a problem that the program may not work.

Further, even if a plurality of programs of different computer systems are installed on a single optical disk 14 to be bootable, the booting mechanism is different due to the difference in hardware, and different types of personal computers may actually be booted. There is a problem that can not be.

Therefore, the present invention has been made in view of the above problems, and a single medium can be operated on a plurality of computer devices.
It is an object of the present invention to provide a computer system that enables it .

Each program of the correspondence means P3 and the correspondence table recording means P6 is recorded.

On the optical disk 33b, for example, each program of the drive name correspondence table T1 and the correspondence table recording means P6 on the disk is recorded. Then, on the optical disc 33c, for example, programs such as applications or OS (P5), parameter setting means P4, OS start-up program P10, and OS (P11) are recorded. The optical discs 33a and 33b also record the OS startup program P10 and the OS (P11).

FIG. 2 shows a flowchart of the boot program operation of FIG. First, the optical disk 33a
Assuming that (33b) is used, when the computer system 21 is started, scanning is performed from SCSI-ID = 1 to ID = 1 to 6 in order from SCSI-ID = 1 to identify the connected optical disk device 33 (ST31). . During scanning (ST32), it is determined whether or not an optical disk device is present (ST33). If it is, it is determined whether or not there is a device configuration correspondence table T1 (ST34). Will be returned.

If the correspondence table T1 exists, the apparatus correspondence table T1 of the optical disk 33a (33b) is read (ST35). Thereafter, the temporary SCSI-ID is associated with the actual SCSI-ID (ST36).

On the other hand, when the above-described scan is completed, the device configuration correspondence table T2 of the semiconductor memory 35 and the startup SCS
The I-ID table T3 is read (ST37). ST

The OS startup program P11 is read from the third optical disk 33a (33b) (ST39), and control is passed to the OS startup program P11 (ST40).

That is, for example, when one personal computer is to be operated on an optical disk owned by each of a plurality of users, a state where the correspondence between the physical drive configuration and the logical drive configuration is “a” when the user “A” is used. Suppose it was Next, when the user B uses, since the correspondence b between the physical drive configuration and the logical drive configuration is recorded on the optical disk (33a (33b)) owned by the user B, the computer 32 reads the correspondence table b. Thus, the operating environment of the computer is automatically adjusted to the state of b.In this way, each user's favorite environment can be realized without any trouble for the user.

The case where the optical disc 33c is used will be briefly described. When a program P5 such as an OS or an application on the optical disc 33c is started, the parameter setting means P4 is executed to change the parameters in the program P5 into the computer device 32. It is adapted to the operating environment.

As a result, the user B can use the optical disc 33c.
In this case, the computer environment a is read before the program is executed, and the parameters in the optical disc 33c are automatically adapted to the environment a. That is, the program can be stored in the computer 32 without the user B having to adjust the computer equipment before executing the program.
It can also be executed on

Each program of the table T2 reading means R4 is recorded.

Here, FIG. 13 shows a flowchart of the operation of FIG. In FIG. 13, as a large flow,
Computer equipment 32a, 32b (either A or B)
When the optical disk device 33 is powered on, the boot ROM 34 is started in the computer device 32a (32b) (ST81), and after a predetermined process (for example, FIG. 3) is performed, the IPL program P1 of the magneto-optical disk 51 is read. The device is activated (ST82).

Then, the section D1 or D2 is activated according to the IPL program P1 (ST83).

In this case, in ST82, any one of the processing of or is performed. In the flow, the model of the computer device 32a (32b) is determined based on the IPL program P1 and the partition management table T4 (ST9).
1) The destination of the section is determined based on the correspondence table T1 or T2 (ST92). Then, the corresponding section D1
Or it moves to D2 (ST93).

In the flow, the model is determined in the same manner as in ST91 (ST101), and the operating environment information E1 of the semiconductor memory 35 is rewritten according to the environment information of the model (ST102). Then, the destination is determined based on the correspondence table T1 or T2 similar to ST92 (ST10).
3), ST1 moving to the corresponding section similar to ST93
04).

Here, FIG. 14 shows a flowchart of the rewriting of the environment information of FIG. 13, and the above-described overall flow will be described. 14, first, an optical disk (magneto-optical disk) 51 is inserted into the optical disk device 33, and for example, the power supply of the computer device A 32a is turned on (ST111, ST111).
ST112). As a result, the boot program B1 is started (ST113), and the IPL program P1 for the computer device A is loaded from the optical disk 51 and executed according to the boot program B1 (ST114).

Therefore, the model identifier I1 is read from the semiconductor memory 35 of the computer device A 32a (ST11).

T117), if present, recognize that the operating environment data of the computer device A32a is D1 (ST11).
8).

Subsequently, the operating environment data D1 for the computer device is read from the optical disk 51 (ST119), and the operating environment information E1 in the semiconductor memory 35 of the computer device A32 is rewritten and set (ST120).

On the other hand, in ST117, the correspondence table T

Therefore, the operating environment of the computer device is first read from the CMOS. The read data is secured in a data storage area in the IPL program and recorded there. Alternatively, data may be recorded in a free area of the disk. Thereafter, when the use of the computer device is completed, the data stored in the IPL or in the free space may be written into the CMOS again and restarted. This operation needs to be prepared in the section of the magneto-optical disk 51 in the command format of the OS being used. Alternatively, the above function may be provided in the power-off command.

Although the above-described first to fourth embodiments show the case where an optical disk (magneto-optical disk) is used as a replaceable storage medium, a replaceable storage medium such as an IC memory card is used. It may be.

Next, FIG. 42 shows a configuration diagram of a replaceable storage medium according to the fifth embodiment of the present invention. FIG. 42 shows a recording format of an optical disk (magneto-optical disk) 120, which is used to realize multi-model startup even in an existing system.

In FIG. 42, the recording format of the optical disc 120 is based on the ECMA Standard 167, and the ECMA Standard defines a logical format of how data is arranged on the optical disc.

[0193] The optical disc 120 has the innermost LBN (Lo
gical Blook Number) = 0, a rewrite area 121 is formed, LBN = 64 to 255, an ECMA logical format recognition area (Recognition) 122 is formed, and LBN = 2
ECMA format descriptor area (De
scriptors) 123 and LBN = 512-1
023, a retreat area 124 is formed. Note that L
BN = 0 to 2175 are for performing system dummy registration.

Then, after LBN = 2176, a logical partition is formed, and the first partition (Pa) in which the first OS is recorded.

In the rewriting area 121, a master boot record or a boot record of each OS (first to third OS) corresponding to each computer device is recorded. The master boot record is a program for loading a boot record used in an existing system into a predetermined location in a memory of a computer device and transferring control. The record of the master boot record or the boot record is recorded in the save area 124.
As another record, the code of the record is stored in the contents of the master boot record rewriting tool, and the code is recorded for each selected model. Section). Note that this rewriting tool is stored in a save area 1 described later.

FIG. 43 is an explanatory diagram of the save area shown in FIG. The save area generally refers to an area that is registered for the system and cannot be used by the user or an area that is reserved as an unused area. The save area 124 in FIG.
For example, a master boot record for the first OS is recorded at LBN = 512, a master boot record for the second OS is recorded at LBN = 515-517, and
The master boot record for the third OS is recorded in LBN = 518 to 520.

FIGS. 44 and 45 show flowcharts of the master boot record algorithm.
In FIG. 44, first, four blocks are read from LBN = 64, and the descriptor (Descriptor) is confirmed (ST25).
1) Search for ID "BEA01" for standard determination (ST2)
52). If the ID "BEA01" does not exist, the boot R
The process proceeds to OM (ST253).

If the ID "BEA01" exists, four blocks are read (ST254), the ECMA format ID "NSR01" is searched (ST255), and the process is repeated until the descriptor end ID "TEA01" is recognized (ST254). ~ 256). And the descriptor end ID
When "TEA01" is confirmed, the process proceeds to the boot ROM (ST257).

On the other hand, the ECMA format ID “NSR
01 "is recognized, as shown in FIG.
Block reading is performed (ST258). The process is repeated until the start-up ID “BOOT1” is recognized (ST258, ST259). When the boot ID is recognized, the process is repeated until the boot ID corresponding to each model is further recognized (ST258 to ST260). ).

That is, it is recognized whether or not the boot ID is correct. If the boot ID is correct, the boot record is loaded to a predetermined address based on the information of the boot descriptor (ST261), and control is passed to this (ST262).

By preparing a master boot record having such an algorithm for each model, it is possible to start computer devices of different models. That is, conventionally, one optical disk has only one boot record and only one model can be started, but in the above-described embodiment, three types of computer devices can be started. It should be noted that the number is not limited to three, and may be more.

Next, the state of use will be described. The optical disk 121 having the above-described contents is prepared, and work is normally performed in a state where the optical disk 121 can be started in the second section. In this section, a program development environment and WINDOWS software are installed, and texts and program codes being created are registered as files. A master boot record and a partition management table that can activate the first partition when using it for another model are stored. Also, a device driver that can read a file in the second section from the first section is installed in advance. If this disk is used for the first OS computer device, it can be started up, and the operation of creating the text or program code in the second section, which was being created earlier, can be continued. In addition, the third O
If there is a computer device for S, it can be started by further rewriting the boot record and the partition management table for the third OS of the third partition, and can create documents and the like.

When the existing computer equipment is used, only the boot partition is valid when only the master boot record or the boot record is replaced, but some partitions having the same OS can be read and written. To do so, it is necessary to replace not only the master boot record or the boot record, but also the partition management table.

Here, the master boot record is E
This is a code for loading a boot record in the case of an optical disk of the CMA logical format. In the case of an optical disk of an existing format, the boot record and the partition management table corresponding to the model are replaced.

As described above, several different types of computer devices can be started with one optical disk, and files can be handled across sections if the OS is the same type.

Incidentally, such an optical disk 121 is EC
Of course, it can be used as MA Standad.
