MATH COPROCESSOR OR ERROR KR-04


What to do if you have problems with spreadsheets, databases, or with the calculator, or if you see error KR-04


General Information

If you are experiencing problems with spreadsheets or databases, or if Calculator fails, but the other programs in NewDeal work fine, the problems might be caused by your math coprocessor. Math coprocessor errors range from inability to load the progrm at all to random crashes while working in one of the programs. System error KR-04 is caused by a problem with your math coprocessor or RAM chips, or by a software conflict.

If you have a Math Coprocessor

NewDeal software can only use Intel® or 100% Intel-compatible math coprocessors. Errors could be caused by a coprocessor that is not 100% Intel-compatible, or by a defective math coprocessor.

NewDeal only uses the math coprocessor in spreadsheets and databases, and in the Calculator, so if you are having problems with those programs, your math coprocessor could be at fault.

Disabling the Math Coprocessor

The easiest solution for this problem is to tell your NewDeal software not to use your math coprocessor. To do this, edit your GEOS.INI file. Find the [math] section and change the line immediately following the section header to read:

coprocessor = none

For example, if your current GEOS.INI file reads:

[math]
coprocessor = intx87ec.geo

You would change it to:

[math]
coprocessor = none

If there is no [math] section in your GEOS.INI file, add both lines to the end of the GEOS.INI file.

NewDeal only uses the math coprocessor in spreadsheets and databases and in the Calculator, so turning off the coprocessor recognition will not slow down most operations.

If You Do Not Have a Math Coprocessor

    • The problem might be caused by a TSR program that is conflicting with NewDeal. The easiest way to test this is by entering

      NEWDEAL /nomem

      to start NewDeal. If you do not get the error message, you are loading a program in your AUTOEXEC.BAT or CONFIG.SYS file that conflicts with your NewDeal software. To find out which program is causing the problem, you will need to edit these files and try removing or REMarking lines, rebooting, and restarting NewDeal (without /nomem).

    • If you get the error when you launch NewDeal using NEWDEAL/nomem , try booting from a floppy disk with no AUTOEXEC.BAT or CONFIG.SYS file on it. To do this, put a blank floppy disk in your A: drive and enter

      FORMAT A: /S

      at any DOS prompt. Leave the diskette in the drive and reboot your computer.

    • If booting from a floppy disk does not help, one or more of your memory chips is probably defective and you may need to have your computer’s memory chips checked by a computer service center.

ANSI.SYS

A customer was getting a „Coprocessor Memory Parity Error“ message. When we removed ANSI.SYS from the CONFIG.SYS file, the problem stopped.
