    TROUBLESHOOTING AN ERROR MESSAGE AFTER INSTALLING A MATH COPROCESSOR

    
       After installing your Intel Math CoProcessor, you may receive one of the
    
       following error messages. Use the suggestions below each error message
    
       to correct the problem: 
    
    
    
    

    WEITEK COPROCESSOR NOT INSTALLED

    
       An error message saying "Weitek coprocessor not installed" may appear on
    
       some systems after you install an Intel math coprocessor. The system
    
       passes all Intel diagnostics and runs all applications flawlessly. This
    
       error is generated because certain Weitek enabling switches were set by
    
       EMM386. 
    
    
    
                 EMM386 [on|off|auto] [w=on|w=off]
    
    
    
       on|off|auto: these parameters activate the EMM386.EXE device driver (if
    
       set to on), or suspends the driver (if set to off).
    
    
    
                 [w=on|w=off]
    
    
    
       If the w=on parameter is specified and the off parameter (different from
    
       the w=off parameter) is not, EMM386 enables the Weitek coprocessor
    
       support. The high memory area (HMA) must be available to enable the
    
       Weitek coprocessor support. If you specify the w=on or w=off parameter
    
       and no Weitek coprocessor is installed in your computer system, MS-DOS
    
       displays the following error message:
    
    
    
                 "Weitek Coprocessor not installed."
    
    
    
    

    OS2 1107 ERROR

    
       When you attempt to run the Intel Math CoProcessor diagnostics on a
    
       system running OS/2 versions 2.0 or 2.1, the following error message
    
       appears: 
    
    
    
                 OS2 1107 
    
    
    
       This error occurs because the Intel math coprocessor diagnostics do not
    
       run under OS/2 versions 2.0 and 2.1. To test the math coprocessor,
    
       insert the diagnostics diskette into your computer's floppy drive, boot
    
       your computer with a DOS system diskette and type the following command:
    
    
    
                 mcpdiags
    
    
    
    

    162 ERROR IN IBM PS/2* MODEL 50,60 & 70

    
       When you install an Intel Math CoProcessor in an IBM PS/2 Model 50, 60
    
       or 70 system, then boot the system, the following message may appear as
    
       the system boots:
    
    
    
                      Error 162  
    
    
    
       The error message occurs because you did not run your computer's
    
    
    
       reference diskette after the math coprocessor was installed in the
    
       computer. To eliminate the error message, boot from your IBM reference
    
       diskette and run the setup program. Select "Automatic" if you haven't
    
       changed the configuration of any add-in cards, and the computer
    
       configures itself to run correctly with the math coprocessor.
    
    
    
    

    "CONFIGURATION ERROR" AFTER REMOVING 80287 FROM IBM PC/AT

    
       If you remove an Intel Math CoProcessor from an IBM PC/AT computer, do
    
       not  rerun your computer's SETUP program to show a change has been made,
    
       and reboot the system, the following message appears:
    
    
    
                 Configuration Error 
    
    
    
       The error message occurs because the computer cannot find the chip.  
    
    
    
       To solve this problem temporarily, unplug the battery from the system
    
       board, run setup and manually enter all the information about your
    
       system.  Note that this process loses all SETUP information, so be sure
    
       to write down the hard drive type, floppy drive type, memory and video
    
       configurations before unplugging the battery. This information is
    
       critical in correctly reconfiguring your computer.
