I put this in config.sys and I'm still getting the error:
config.sys:
SHELL=C:\FDOS\BIN\CMDXSWP.COM /F /P=C:\AUTOEXEC.BAT
TIA for any help with this.

Turbo C code:

disable();
OrigCritErrHandler = getvect(24);
setvect(24, NewCritErrHandler);
enable();

disable();
setvect(24, OrigCritErrHandler);
OrigCritErrHandler = NULL;
