PREMIUM II 486SX/20 AND LOTUS 123 RELEASE 3.1
|
||
|
|
|
||
|
|
|
||
|
|
SYMPTOM: Unable to input numeric values into the Lotus 3.1 worksheet.
|
||
|
|
The numeric values appear only as zeros while alphanumeric
|
||
|
|
values are fine.
|
||
|
|
|
||
|
|
PROBLEM: Lotus 3.1 recognizes that the system has a 80486 Processor and
|
||
|
|
assumes that there is a Math Coprocessor available. This is
|
||
|
|
true for the 80486DX Intel Chip but not for the 80486SX. When
|
||
|
|
a Math Coprocessor is present, Lotus passes on the tasks of
|
||
|
|
numeric calculations to the Math Coprocessor which is not
|
||
|
|
available in the Premium II 486SX/20 as a standard option.
|
||
|
|
This can be checked by accessing the Worksheet Status Menu
|
||
|
|
option which will show the system information such as;
|
||
|
|
Available memory, Processor type, Math Coprocessor type and
|
||
|
|
other Lotus configuration information.
|
||
|
|
|
||
|
|
SOLUTION: By typing "123 -s" at the Lotus 3.1 prompt the Premium II
|
||
|
|
486SX/20 system will be recognized as a 80386 system with no
|
||
|
|
Math Coprocessor, enabling Lotus to handle the numeric
|
||
|
|
calculations. The "-s" switch instructs Lotus that the
|
||
|
|
system has a 386 Processor with no Math Coprocessor instead of
|
||
|
|
a 486 Processor. This will allow the Premium II 486SX/20 to
|
||
|
|
be able to input numeric data.
|
||
|
|
|
||
|
|
Lotus is also aware of this issue and customers can contact
|
||
|
|
Lotus at (800) 343-5414 and order the Lotus 3.1 update which
|
||
|
|
resolves this problem. With this update the Lotus program
|
||
|
|
will no longer assume that the 80486 Processor has a built-in
|
||
|
|
Math Coprocessor and the "-s" parameter will no longer be
|
||
|
|
necessary.
