SUMMARY
=======
Strange behavior with applications that use math coprocessors (Microsoft Excel,
for instance) can be due to the BIOS reporting the presence of a math
coprocessor when one does not exist. For example, if you have a 486SX machine
with a BIOS designed for a 486DX and you type a number in Microsoft Excel, an
incorrect floating-point number is displayed.
MORE INFORMATION
================
Windows issues an INT 11h (equipment check) function call to determine whether a
math coprocessor is present.
Do the following to determine test whether there is a coprocessor detection
problem on a computer:
1. Run Microsoft Diagnostics (MSD).
2. Choose the Computer option.
3. If a coprocessor is detected, and the machine does not have one, the BIOS
will need to be replaced with a BIOS that does not incorrectly report a
non-existent coprocessor.
