REGISTER THIS SOFTWARE AND PAY BEFORE YOU INSTALL IT TYPE FPUFIX /R from the DOS prompt to register this copy of FPU-Fix for your PC. You will be asked to assert that you have paid the registration fee to Stage Research. Once registered, you will no longer see the message about registration of the software. BACKGROUND: All Intel Pentium processors created and sold during 1993 and 1994, as well as many sold during 1995 contain a bug which mis-calculates the results of the division by certain relatively large numbers. Intel has said that the problem is very unlikely to occur during the average life of a computer. However, the problem is easy to demonstrate in a spreadsheet or by using a PC's calculator software. It can affect the accuracy of fourth digit in a division operation (that is, instead of a result like 22,888 you might get something like 22,891). FPUFIX.EXE is both a Windows and DOS program which detects which Pentium processors are affected by this bug in the FPU (Floating Point Unit) by actually testing for the problem. It also provides a solution to the problem. To fix the bug, FPUFIX.EXE changes the state of the Pentium computer for certain functions which results in the correct processing of the otherwise faulty FPU division. Most software applications are made to believe that the floating-point unit is turned off, though technically it is still present and functioning. Since most software applications believe the FPU is not present or not available, they use their own internal code along with the main processor (not the FPU) portion of the Pentium to make the same calculation and the result is correct. After FPUFIX is run, the calculation of spreadsheet data, database reports, calculators, financial and accounting software (and other math-oriented software) might slow slightly but the division errors will not occur. Actually, in testing, the performance hit it is so slight that it is difficult to measure and even more difficult to notice for virtually all business productivity software. Other aspects of the machine's performance are not affected. Applications which depend heavily upon the FPU such as days-long engineering calculations involving large prime numbers are likely to slow measurably. FPUFIX was tested with dozens of Windows applications (like Excel, 123, Quattro Pro, Dbase, Works, Foxpro, Calculators, Quicken, MS-Money, etc.), and had the desired result for all applications tested. However for some DOS applications, FPUFIX had no effect whatsoever. These DOS applications blindly use the FPU even when it is advertised as "not available." NOT A TSR FPUFIX is not a TSR nor is it a Device driver. It uses no memory and uses no system resources or environment variables. It does not patch or modify any software or files on your hard drive in any way. FPUFIX must be run before MS Windows loads or it will not work for applications which run in Windows. In DOS, FPUFIX must be run before the DOS application whose calculations you want to trust. Once run, the FPU will continue to be "unavailable" until the PC is rebooted. During the next boot-up there is no residual effect on the system or its software whatsoever from having run FPUFIX. FPUFIX will not cause any software to have errors that were not there before FPUFIX was run. INSTALLATION using DOS To install FPUFIX simply copy the two files (FPUFIX.EXE and FPU-READ.ME) to the same directory on your hard drive. For example copy the files to C:\DOS. Then edit your AUTOEXEC.BAT file and add the line: C:\DOS\FPUFIX.EXE That is all there is to it. When your system next boots up, you will see a registration message from FPUFIX until you run the program FPUFIX followed by a /R and affirm that you have paid Stage Research the registration fee. After you register FPUFIX, you will not see any evidence that it is running. INSTALLATION using Windows To install FPUFIX from within Windows, simply copy the two FPU files (FPUFIX.EXE and FPU_READ.ME) the directory on your hard drive. For example copy the files to C:\DOS. Then use the RUN command from the Windows File menu to Run the program C:\DOS\FPUFIX.EXE (or double click on the FPUFIX.EXE file name from within Windows file manager). Read the screens and click on . Read the screen that asks if it is OK to update your AUTOEXEC.BAT and click on . The next time your computer boots-up FPUFIX will be running. You can verify this by running it again from within Windows. The screen will show that your floating point calculation now achieves the correct result and that your floating point operations are now working correctly. When your system next boots up, you will see a registration message from FPUFIX until you run the program FPUFIX followed by a /R and affirm that you have paid Stage Research the registration fee. After you register FPUFIX, you will not see any evidence that it is running. TESTING FPUFIX FOR YOUR PARTICULAR APPLICATION SOFTWARE If you want to get the reassurance that FPUFIX is working you can ask your application to perform the following calculation both without running FPUFIX first, then after running FPUFIX: (4,195,835/3,145,727) x 3,145,727= if you get an answer like 4,195,579, then the FPU is in error if you get 4,195,835, then FPUFIX is working. FUNCTIONS (DOS command line for FPUFIX.EXE): FPUFIX.EXE /R Register.
