MCP Installation Troubleshooting: Software Does Not Function
Contents:
TROUBLESHOOTING PROBLEMS WITH SOFTWARE AFTER INSTALLING AN INTEL MATH COPROCESSOR
Use the following solutions with software after installing an Intel math
coprocessor
SYMPHONY @NA FUNCTION & LOTUS 1-2-3
The @NA function in Lotus 1-2-3 v2.01 and early versions of Symphony
does not work correctly on a system with an Intel387 DX installed. The
problem has been corrected in Lotus 1-2-3 v2.2. The phone number for
Lotus Development is 617-253-9150.
CADKEY
CadKey released a 32-bit version of their 3D CAD software, which can
cause errors while drawing arcs and redrawing images. Contact CADKey
technical support at 800-CADKEY0 FAX: 203-649-8231
ASYST AND THE INTEL387 DX MATH COPROCESSOR
ASYST Rev 1.56 and earlier are not compatible with the Intel387 DX Math
Coprocessor. Contact ASYST for a patch which fixes the problem.
LOTUS 1-2-3: GARBAGE IN CELLS
A defective math coprocessor can cause unpredictable values in number
cells. Test your math coprocessor with Intel's CHKCOP program. Download
the program with your modem available through Intel's online services or
contact Intel Customer Support.
BASIC INTERPRETERS SUPPORTING THE 8087
The PC Tech Journal, June 1986 issue compared seven versions of Basic.
Here is their chart on math coprocessor support taken from page 52 of
that issue. Better Basic was judged the best in the review.
PRODUCT: VERSION 8087 / 80287 SUPPORT
BASICA 3.0 NO
BETTER BASIC 2.0 OPTIONAL
BUSINESS BASIC 7.3 NO
MEGA-BASIC 5.23 NO
PRO. BASIC 2.04 OPTIONAL
TRUE BASIC 1.0 YES
WATCOM BASIC 2.5 YES
TURBO BASIC` YES (BORLAND)
QUICKBASIC YES (MICROSOFT)
LOTUS 1-2-3 REL3.1 AND INTEL486 SX CPU
Running Lotus* 1-2-3 rel3.1 on a machine installed with an Intel486(TM)
SX CPU can cause zeros or "err" to appear in the cells. The problem
occurs because the Lotus software interprets the Intel486 CPU as
containing a built in math coprocessor, which is not true for the
Intel486 SX CPU. To correct the problem, call Lotus Development Corp.
to request an update kit for rel3.1.
MICROSOFT FORTRAN COMPILER V 4.0
Microsoft Fortran* v4.0 is not compatible with the Intel387 Math
Coprocessor. It works fine with the 80287. Contact Microsoft for more
information.
