                                                  The root cause of this problem appears to be the software
                                                  libraries that come with the compiler. Any compilers that
                                                  are dependent on software-based timing loops are affected,
                                                  but this issue is specifically known to affect Borlands
                                                  TurboPascal compilers.

                                                  If you have a piece of software that was compiled on a
                                                  Borland Turbo Pascal compiler, you will likely encounter
                                                  this problem when run at speeds of 233 MHz and higher. One
                                                  possible solution is to contact your software vendor to
                                                  see if they have a newer version of that software that is
                                                  not dependent on timing loops.

                                                  Intel is also aware of two patches for this problem, one
                                                  for programs that have been compiled with a Borland
                                                  TurboPascal compiler, and one that will patch the software
                                                  libraries of the compiler itself.

                                                  Intel has worked with Inprise (formerly Borland), and
                                                  Inprise has communicated that there is more information
                                                  about this problem on the Inprise Developer Support web
                                                  site.
