Incorrectly Detected Coprocessor May Cause Improper Display (84166)
The information in this article applies to:
- Microsoft Windows 3.0
- Microsoft Windows 3.1
- Microsoft Windows 3.11
This article was previously published under Q84166 SUMMARY
If a computer's BIOS incorrectly detects a math coprocessor when one
is not present, improper information may be displayed in areas such as
the title bar of the Microsoft Windows Calculator program and in other
Windows-based programs.
Phoenix technical support has confirmed that some system manufacturers
might have incorrectly shipped BIOS that supports the Intel 80486DX
only, not the BIOS that also supports the Intel 80486SX chip. This
situation causes the erroneous reporting of a math coprocessor on the
80486SX when there is none, and may produce these errors.
MORE INFORMATION
The incorrect detection of a math coprocessor can cause problems in
Windows. The value "-1" may be displayed for the cursor position.
Strings such as "sin:" or "sqrt:" may be displayed randomly in title
bars and other places. The value "-1#.QNAN" might be displayed if the
Clear button is chosen in Calculator.
To resolve this problem, contact your computer manufacturer, not
Phoenix for the correct BIOS for your computer system.

vendors independent of Microsoft; we make no warranty, implied or
