[code fragment that fools around with interrupt vectors]

The code fragment provided in the quoted article directly manipulates
the interrupt vectors in low memory.  Please don't do this.  But if you
must, please don't ask others to do this!  User applications have no
business bypassing the standard operating system-provided interfaces.
MS-DOS provides system calls that let you change the address of the
critical error handler.  These should be used.
