Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an exchangeable storage medium as an external storage medium for computer equipment and a computer system. In recent years, an optical disk using the magneto-optical effect has been used as a portable and rewritable mass storage medium. Attention has been paid. It can store a large capacity of 128 Mbytes on a single optical disk and has a small 3.5-inch portability. It can store and carry various information such as the OS (operating system) and application programs. it can. Further, there is an IC card or the like as the exchangeable storage medium, which is smaller as a portable one as described above.

Therefore, it is desired that a storage medium such as a single optical disk can be properly 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, it has not been changed. Such a correspondence table of the physical drive configuration and the logical drive configuration is recorded in, for example, a battery backup type semiconductor memory in a computer device.

Further, since the OS and application programs mounted on such a fixed magnetic disk always operate under the same environment, it is general that once the parameters are determined, they cannot be changed. .. Therefore, for example, even if the data created by a computer system is transferred to a floppy disk and is operated by another computer system, it cannot be used unless an application program corresponding to the other computer system is installed. 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 computer system, and FIG. 47 is an explanatory diagram of a table on the semiconductor memory of FIG.

In FIG. 46, the computer 11 as a computer device has a SCSI (Small Computer Systems In
An optical disk device 13 is connected through the terface) 12. The optical disk 14 is driven by the optical disk device 13. Let these systems be A, and a plurality of systems (for example, A and B) are constituted.

The personal computer 11 has a disk 21 and 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 read program P7 for reading the correspondence table between the physical drive and the logical drive on the semiconductor memory 23, and a boot program B2 for the correspondence means P3 for the physical drive and the logical drive.

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

Further, the optical disc 14 has an OS (Oprati
on System) start-up program P10, OS (P11), program P5 such as an application are recorded, and here, presentation tool P8, screen data P9, and test driver P12 are also recorded.

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

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

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

When the power of the personal computer 11 is turned on, the boot program B2 in the boot ROM 22 starts to operate (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 with a logical drive name, and therefore 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. 47 (A), it recognizes that the startup SCSI-ID is 1 and recognizes that the logical drive name is E (ST6).

Next, the OS recorded in the optical disk 14
The boot program P10 is read, and control is passed to this program (ST7), and the OS (P
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 the driver group for controlling the external device) is read from the logical drive E (in this case, the optical disk 14a) (ST9). This read destination drive name is a logical drive name and is stored as a parameter in the OS. In this example, the parameter is “E drive”. Then, the OS starts up (ST10). Then, the presentation tool P8 is read from the optical disc 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 is completed, the program P5 such as an application is read and executed.

By the way, in another system B having the same configuration, considering that it is used by many users, the contents of the correspondence table T2 between the physical drive and the logical drive are not fixed so as to be rewritable. It is recorded as shown in 47 (B), and SCSI-ID = 2.

In this case, since the presentation tool 18 written on the optical disk 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 set as shown in FIG.
7 (A) is rewritten to make the operating environment of system B the same as the operating environment of 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 is stored on the single optical disk 14.
Even if (P11) and the program P8 for presentation 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 is set. It has to be changed manually, which requires complicated operation.

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

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

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

Here, FIG. 51 shows an operation flow of the application program. In FIG. 51, first, in the system A, the optical disk 14 is the optical disk device 13
Inserted in (ST21), power on the PC 11
The state is set (ST22). This allows the boot ROM 2
The boot program B2 in 2 starts up (ST23), loads the personal computer IPL (P1) from the optical disc 14 and executes it, and passes control to it (ST24).

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

Then, based on the read operating environment information, the OS starting program P10 is read, the OS (P11) for the personal computer 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 RAM drive logical drive name for the application secured on the extended 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 by these logical drive names.

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

On the other hand, when the same optical disk 14 is used for another system B for spreadsheet calculation, the system A and system B have different operating environment information (FIG. 50 (A),
(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 also uses the same optical disk 14 to perform work.

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

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

Therefore, in the system A, the word processor software P13 for A personal computer recorded in the hard disk in the hard disk device 15 is operated to create a document,
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 device 15 is started up and the word processor software P for the B personal computer is set.
14 is operated. Therefore, the floppy disk device 16
Through the document data P15 in the floppy disk 16a
Is moved to the hard disk device 15 and the document creation is similarly continued.

The word processor software can be assigned to a function key to realize the function with one touch, but this 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 performing the same work in different systems, it is necessary to move the document in the hard disk to the floppy disk 16a once, and to change the key assignment and 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 systems A and B, but the A personal computer 11a of system A has 8 MB of expanded memory, and the A personal computer 11a of system B has 1 MB of expanded memory. It is a thing. Further, instead of the floppy disk device 16, the optical disk device 13 is connected together, 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 processor software P13 in the system A, it is assumed that the word processor software P13 requires 2 MB of expansion memory. When the optical disc 14 is used in the system B, the word processor software P13 of the optical disc 14 cannot be used due to the difference in the expansion memory. Therefore, the word processor software P16, which is the same word processor software and has a function limiting plate that does not require expansion memory, is installed in the hard disk device 1.
The optical disc 14 is used by installing the optical disc 14 in the optical disc 5.

As described above, even if the personal computers of the same model have different operating environments such as different expansion memories, the word processor software to be used must be changed.

By the way, various OSs of personal computers currently exist, but these systems are installed in a hard disk and the personal computer is booted from there. Also, the OS
However, if the computer model is different, it cannot be started due to the difference in hardware. Depending on the OS, the hard disk can be divided into several sections for use. That is, it can be handled as if there are different types of hard disks divided into logical drives. This is generally called a multi-compartment. in this case,
Different systems can be installed in each partition, and several OSs can be used in one personal computer.

However, since the hard disk is not portable, the system was never used by going to another place. Also, the disk cannot be connected to a computer of a different type and booted. This is because if the model is different, even if the OS of the same type is used, there is a hardware-dependent part, and the operation stops at that part.

Therefore, an optical disk (magneto-optical disk) having a larger capacity than that of a floppy disk can be used, and several systems can be installed on one optical disk to start up with different models. There is.

[0044]

However, as described above, when a plurality of users operate computer equipment such as a single personal computer with their own optical disks, physical operation is performed by input means such as a keyboard each time. You have to reset the correspondence between the dynamic drive configuration and the logical drive configuration to adjust the operating environment of the computer,
There is a problem that complicated operations are required.

Further, when creating the same type of data in different computer systems, it is necessary to install the program corresponding to the corresponding computer system, and even if it is installed, it is necessary to transfer the data to the floppy disk once. .. On the other hand, when a soft program is customized in a predetermined computer system, there is a problem that the similar soft program must be customized again in another computer system.

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

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

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

On the optical disc 33b, for example, the programs of the drive name correspondence table T1 and the correspondence table recording means P6 on the disc are recorded. The optical disc 33c stores, for example, a program such as an application or an OS (P5), a parameter setting unit P4, an OS boot program P10, and an OS (P11). The OS boot program P10 and the OS (P11) are also recorded on the optical disks 33a and 33b.

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

When the correspondence table T1 exists, the device correspondence table T1 of the optical disc 33a (33b) is read (ST35). After that, the temporary SCSI-ID and the actual SCSI-ID are associated with each other (ST36).

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

The OS boot program P11 is read from the optical disc 33a (33b) of No. 3 (ST39), and the control is passed to this OS boot program P11 (ST40).

That is, for example, when a single personal computer is to be operated by optical disks owned by a plurality of users, the correspondence between the physical drive configuration and the logical drive configuration is a when the user A uses it. It was Next, when the user B uses it, since the correspondence b between the physical drive configuration and the logical drive configuration is recorded on the optical disc (33a (33b) owned by the user B, the computer 32 reads the correspondence table b.

52). Boot R if ID "BEA01" does not exist
Transition to OM (ST253).

If the ID "BEA01" is present, 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 descriptor end ID
When "TEA01" is confirmed, the boot ROM is entered (ST257).

On the other hand, the ECMA format ID "NSR"
If "01" is recognized, as shown in FIG.
Block reading is performed (ST258). Then, the process is repeated until the startup ID "BOOT1" is recognized (ST258, ST259), and when it is recognized, the process is repeated until the boot ID corresponding to each model is recognized (ST258 to ST260). ).

That is, whether or not the boot ID is correct is recognized, and if it is correct, the boot record is loaded into 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, computer devices of different models can be activated. That is, conventionally, only one boot record is provided on one optical disk, and only one model can be activated. However, in the above-described embodiment, three types of computer devices can be activated. Note that the number of models is not limited to three and may be more.

Next, the usage status will be described. The optical disc 121 having the above-mentioned contents is prepared, and normally the work is performed in a state where the optical disc 121 can be activated in the second section. In this section, a program development environment and WIDOWS software are installed, and the text being created and the program code are registered as files. A master boot record and a partition management table are set so that the first partition can be activated when it is used for another model. Also, a device driver that can read the files of the second partition from the first partition is installed. If this disk is used for the first computer device for OS, the disk can be started up, and further, the work of creating the text or program code in the second section, which is being created, can be continued. Also, the third O
If there is a computer device for S, it can be started by rewriting the boot record and the partition management table for the third OS of the third partition, and a document or the like can be created.

In the case of using the existing computer equipment, only the boot partition is valid when the master boot record or only 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 boot record but also the partition management table together.

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

In this way, it is possible to start several different types of computer equipment with one optical disk, and if the OSs are of the same type, it is possible to handle files across partitions.

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