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.
