## Title
Universal driver server

## Abstract

This invention involves using an alternative driver that is located in a specified server on the Internet. For example, a person could take a floppy disk that is not compatible with their computer and transform it over the Internet through an alternate compatible driver. In order to do this, a special universal bit reader is located within the server. A second variant is that a bit reader would be located in a user's computer and it would be connected to a global server. So, all the files could be accessed through the Internet. This would allow to read and write data from/to a disk that was formatted on a different operational system. In order to solve a problem how to run applications that are not compatible to the operational system on a computer where this disk was inserted, the invention teaches the following approach. A universal driver on the server uses a program that looks for similar applications in a database server that contains a database of applications from different operational systems. The universal driver can identify what programs in the application are needed either reading names of programs on the disk or it can read a special table in which applications point to programs in different operational systems.

## Background
CROSS-REFERENCE TO RELATED APPLICATION
This application is a continuation application of U.S. patent application Ser. No. 09/564,619 filed May 4, 2000, now U.S. Pat. No. 7,089,562, the entire disclosure of which is hereby incorporated herein by reference in its entirety.


BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to computer systems. More specifically, the invention relates to methods and procedures for allowing a computer to work with input data that is in a format nominally incompatible with the computer
2. Discussion of the Prior Art
Today, computer systems, e.g., PC or Apple, are associated with many different processor types, e.g., Intel, Motorola, RISC, and include various operating system platforms, e.g., Windows, UNIX, OS/2 etc. Each of these computer system devices generally include a floppy disk drive or CD-ROM drive enabling a disk to be inserted into the system for reading data therefrom or data thereto. Typical problems that exist today largely deal with compatibility, where disks having programs readable and/or executable on one computing system platform, e.g., an Apple computer, may not be read or executed on another computing system platform. For example, if a student receives a game from one of his friends on a floppy disk who has a different computer system than his friends, that student would not be able to play the game because the software would not be compatible with his computer.
Some computer systems provide for the simulation of a disk driver of other, different operational systems. This requires the installation of software that enables a computer controlled with one operational system to read a floppy disk or CD-ROM that was formatted in another operational system. This solution is not very convenient since there are many other different operational systems and it takes a lot of memory to install many drivers for all existing operational systems into one computer. Also operational systems are often upgraded. Therefore, simulation of other operational systems on a PC may quickly become obsolete.
Another problem with simulators of other operational system drivers is that they allow only a limited number of operations, such as reading and writing files. They usually do not allow the execution of complex applications intended to be run on a different operational system.
Efforts have been made to create an operational system that is compatible with other operational systems (for example, Apple, UNIX, and Intel). So far, however, these efforts have not been completely successful due to the complexity of different operational systems. Furthermore, the platform-independent software approach, e.g., Java, enables the execution of applications that are written in Java to run on different operational systems, but still does not allow the reading of data from incompatible floppy/CD-ROM disks.
SUMMARY OF THE INVENTION
An object of the present invention is to provide an alternative compatible driver that is located in a specified server accessible via the Internet for transforming the incompatible data to a format compatible with the user's computer.
Another object of the present invention is to provide an alternative compatible driver employing a universal bit reader that is located in a specified server accessible via the Internet for transforming the incompatible data to a format compatible with the user's computer. Alternately, a bit reader could be located in a user's computer.
In accordance with the present invention, for example, a person could take a floppy disk that is not compatible with their computer and transform the disk over the Internet through an alternate compatible driver. In order to do this, a special universal bit reader is located within the server. A second variant is that a bit reader would be located in a user's computer, and the reader would be connected to a global server. So, all the files could be accessed through the Internet. This would enable users to read and write data from/to a disk that was formatted on a different operational system.
According to the principles of the invention, there is provided a web server employing a universal driver that enables execution of an application given on a disk, for example, that is not compatible with the operation system on the computer where the application is desired to be run or installed. A universal driver implemented in a server device implements a program that searches for similar applications in a database server that comprises many applications from different operation systems. The purpose of the search is to identify what programs in the application are needed, for example, by reading names of the incompatible programs on the disk. This is enabled by the fact that like programs for the same applications written for different operational systems usually have common prefixes.
Alternately, the driver may read a special table in which applications point to programs in different operational systems.
For example, if a computer game intended to run only on an Apple machine is attempted to be installed on an Intel based computer, the universal driver would go on the specified database server and download similar applications that are compatible for the user's computer. The universal driver can identify what programs in the application are needed either reading names of programs on the disk (the programs for the same applications written for different operational systems are usually have common prefixes) or it can read a special table in which applications point to programs in different operational systems. Advantageously, the system may be used with a computer game intended to run only on an Apple machine is attempted to be installed on an Intel based computer.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS OF THE INVENTION
The present invention is a universal driver apparatus 100 that enables a user to execute programs, generated on one computing platform, on another, incompatible computing platform.
FIG. 1 illustrates the universal driver apparatus incorporating a universal virtual floppy disk and CD-ROM driver. A first computing system includes a first driver A for reading and writing to a floppy disk 102. For purposes of discussion, the floppy disk 102 is assumed to have been formatted for use on an non-compatible operating system and is attempted to be run on the Driver A of the first computing system 101. As shown in FIG. 1, the PC includes a bit-reader 113. As the PC is unable to process the information on the disk the bit contents read by the bit reader are transmitted to the universal driver server 105 via network 103.
Based on the bits read, the universal driver 105 identifies in what operational system the disk 102 was formatted. The universal driver server 105 particularly activates a corresponding operational system from the database server 107 that contains different operational systems. Then, the universal driver performs some operations, such as read and write data from/to the disk 102 that was formatted on a different operational system or run applications on the disk 102 using the operational system on the server 107. The output from the running of the applications on 105 will be sent to the user on PC 101 after this output is reformatted to the user operational system. Of course, this approach cannot be used if the task of application is not to produce some output file (e.g. a music or text).
If the user would like to download files from 102 to a memory in the computer 101 then he can format files on the disk 102 into a format that is compatible with the operational system in 101. This reformatting is done in the universal formatting system that is described in the patent application Ser. No. 09/564,617, filed herewith, for “Real Time Backup System For Computer Users”. For example, the person may want to store ASCII file from the disk 102 to the computer 101. ASCII data has different representation in different operational systems (for example, 4 bytes numbers A1 A2 in Intel are represented as A2 A1 in Unix, where A1 and A2 are two byte numbers). Examples of simple applications that can be run on PC after they were reformatted from the disk 102 in 108 are programs that are written as scripts that do not require compilations (e.g. perl script).
The universal driver also can download some special applications directly to the PC 101 if these applications can be run on PC in 101 (despite the fact that PC 101 is controlled by a different operational system). Examples of such application are programs that are written as scripts. For example, Perl script that was written for one operational system usually can be run in different operational systems (with little or no changes) that contain means for running Perl scripts. Perl source is represented as a text file (e.g. ASCII) and to run it in another operational system, only small changes may be needed.
In order to run more complex applications that are not compatible with the operational system on a computer, where this disk was inserted, the invention teaches the following approach. A universal driver 105 on the server uses a module that looks for similar applications in a database server 104 that contains a database of applications from different operational systems. For example, if a computer game only compatible for apple was trying to be installed into an Intel computer, the universal driver would go on the specified database server and download similar applications that are compatible for the user's computer. The universal driver can identify what programs in the application are needed, either reading names of programs on the disk (the programs for the same applications written for different operational systems usually have common prefixes), or the universal can read a special table in which applications point to programs in different operational systems.
FIG. 2 explains the setup drivers. After the identifier of the type of driver 202 distinguishes what type of operating system the data program was meant for, the data is sent to 203, where the data is recognized by an activator of corresponding driver operational systems. This means, when the compatible system for the data is found, the data are connected to that driver. For example, if a program was only compatible with Apple, the server would identify that and then connect the program to an Apple driver. For the data to be connected with the correct driver, the data must process through the reader information in the driver 204. After the data is read, the data are sent to the access of the operation system 205. This is all sent to the server of operating system, where the changes can take place. 201 is responsible for formatting data to an operating user system. Then, this information is sent back to the user/sender 200 in the usable format.
FIG. 3 explains some of work that is done in the module “formatting of data” 201. The data from a user (disk, CD-ROM, and tape) 300 is sent to the identifier of application OS 301. The data base of Applications 302 is where 301 searches for programs that are compatible with the ones in need of format. If a compatible program is found, that program is then downloaded into the corresponding operating system 303. The compatible program is finally downloaded into the user's computer 304.
FIG. 4 is a flowchart of the method. At 400, first a disk, CD-ROM, or tape is inserted into the PC. At 401, the bits are read. At 402, the bits are sent to the operating system's identification server 410. At 403, the bits are sent to the operating system of the inserted disk, tape, or CD-ROM. At 405, the data are read. At 406, the method identifies the type of application. At 407, the method checks whether the same application exists for OS of the PC. At 408, the method downloads any compatible files, if they exist. At 409, the method reformats the files to OS of the user's computer, if the application does not exist in another OS.
While it is apparent that the invention herein disclosed is well calculated to fulfill the objects stated above, it will be appreciated that numerous modifications and embodiments may be devised by those skilled in the art, and it is intended that the appended claims cover all such modifications and embodiments as fall within the true spirit and scope of the present invention.
