How to solve the error message KR-04: Coprocessor/Memory Parity Error

This error message 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. The KR-04 error could be caused by a coprocessor that isn't 100% Intel-compatible, or by a defective math coprocessor.

The easiest solution for this problem is to tell your NewDeal 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:
coprocessor = intx87ec.geo
You would change it to:
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 software only uses the math coprocessor in NewCalc, NewFile, and Calculator, so turning off the coprocessor recognition will not slow down most operations.

If you don't have a Math Coprocessor

  1. 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 don't 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 re-entering NewDeal (without /nomem).
  2. 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.
  3. If booting from a floppy disk doesn't 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.
