Abstract

PURPOSE:To attain the use of an application program which is produced by supposing an environment where two floppy disks are available with no change of the application program even with the actual use of a single floppy disk device by providing a memory backed up with a battery, a copy function, and a file control function. CONSTITUTION:A memory 5 has the capacity equal to or larger than that of a floppy disk device 6 and a battery back-up function. A copy function 41 copies all data stored in a floppy disk to the memory 5 at the start of a system. Then a file control function 42 performs the control to treat the data on the memory 5 in a manner exactly equal to that of the data stored in the floppy disk of the device 6. In such a constitution, it is possible to use an application program produced supposing an environment where two disks 6 are available without changing the program.

Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to a data processing method, and in particular, a data processing method related to floppy disk control and memory control in a personal computer system [Prior Art] Conventionally, this type of data processing has been performed. In this method, the function (hereinafter referred to as pseudo disk function) that treats the memory in a personal computer system as a file medium equivalent to a floppy disk (the same goes for a hard disk) is the O3 (Operating function) of a personal computer system.
RAM (Ra
nd.

(Access Memory) disk function.

Therefore, the contents of the pseudo disk function differed depending on the type of RAM disk function in 05CO3.

For this reason, for example, an application program that is assumed to be operated in an environment equipped with two floppy disk devices (an environment that can handle two floppy disks) may be installed with only one floppy disk device. (an environment where one floppy disk and memory with the same capacity as the floppy disk are handled), or even if it can be operated, there are There were some interfaces that required modification.

[Invention tries to solve! l! In the conventional data processing method described above, the pseudo disk function is realized by the RAM disk function in the O3, so the content of the pseudo disk function differs depending on the type of O3, and two floppy disk devices are used. The disadvantage is that an application program that is intended to be operated in an environment equipped with a floppy disk may need to be modified in order to operate it in an environment equipped with only one floppy disk. (This may result in a situation where commercially available application programs cannot be used as is.)

In view of the above-mentioned points, the purpose of the present invention is to assume an environment in which a personal computer system equipped with only one floppy disk device is equipped with two floppy disk devices regardless of the type of O3. The object of the present invention is to provide a data processing method that can be used without changing application programs created as .

[Means to solve the problem]

The data processing method of the present invention is a data processing method for a personal computer system equipped with a floppy disk device, and includes a battery bank up memory having a capacity equal to or greater than that of the floppy disk device and a battery backup function; A copy function for copying all the data in the Fremby disk on the Fremby disk device to the memory with battery bank up when starting up the personal computer system, and the Panteri bank amplifier copied by this copy function. A file sub-door that controls the data in the attached memory to be treated exactly the same as the data in the floppy disk on the Fronby disk device.
A-ability.

[Effect]

In the data processing system of the present invention, the memory with battery bank up has a capacity equal to or larger than that of a floppy disk device and has a battery bank up function, and the copy function is activated when starting up a personal computer system. The file control function copies all the data in the floppy disk on the device to the memory with buffer backup, and the file control function copies the data in the memory with buffer backup copied by the copy function to the floppy disk on the floppy disk device. Performs control that treats it exactly the same as data.

〔Example〕

Next, the present invention will be explained with reference to the drawings.

FIG. 1 is a block diagram showing the configuration of an embodiment of the data processing method of the present invention (a personal computer system to which the data processing method is applied). The data processing method of this embodiment uses a CPU (Central Processor) that executes O3 and application programs.

The system bus 3 to which the main memory 2 and file control unit 4 are connected, the file control unit 4 that controls the memory 5 with battery bank up and the floppy disk device 6, and the floppy disk on the floppy disk device 6 are the same or larger. , a floppy disk device 6 into which a floppy disk is loaded, and a file control section 4. It is configured to include a memory 5 with battery backup and a local bus 7 to which a floppy disk device 6 is connected.

The file control unit 4 copies all the data in the Freonby disk on the floppy disk device 6 to the memory 5 with battery bank up when starting up the personal computer system (when it is turned on or when the system is reset). function 41, and a file control function 42 that performs control to treat data in the battery-backed memory 5 copied by the copy function 41 in exactly the same way as the data in the floppy disk on the floppy disk device 6. There is.

Next, the operation of the data processing system of this embodiment configured as described above will be explained.

When the personal computer system to which the data processing method of this embodiment is applied is powered on or when the system is reset, copy 1! tt 41 is
All the data in the floppy disk on the floppy disk device 6 is read out via the local bus 7 and stored in the memory 5 with battery backup.

After such copying is performed, the file control unit 4
The file control JIj, function 42 in the CPUI (C
The interface between the data in the memory 5 with panteri backup (O3 and application programs, etc. in the main memory 2 executed by the CPU 1 and the data in the Fronby disk on the floppy disk device 6) Performs control that treats the interface as the same as the interface between the two.

As a result, O3 and application programs in main memory 2 transfer data in memory 5 with buffer bank amplifier to floppy disk device 6 via system bus 3, file control unit 4 and local bus 7.
It becomes possible to handle the data exactly the same as the data on the floppy disk above.

〔Effect of the invention〕

As explained above, the present invention provides a memory with battery backup, a copy function, and a file control function, thereby eliminating the need for the conventional RAM disk function and enabling a personal computer system equipped with only one floppy disk device to be used. O3 in the environment
It is possible to make it appear as if two floppy disk drives exist from the O8 and application programs (similarly, even in a personal computer system environment with only two floppy disk drives, O8 and application programs can It becomes possible to make it appear as if three Fronby disk devices exist.

In the case of boat fishing, this has the effect of allowing O5 and application programs to see one more floppy disk device than is actually provided.

As a result, in a personal computer system equipped with only one Frembie disk device,
Regardless of the type of O3, the floppy disk drive is
This has the effect that application programs created on the assumption that the computer is installed can be used without modification.
