If the instructions in the PATCH87.DOC file for using PATCH87.EXE
are followed through Step 4 of the "Do I Need to Use This Program?"
section, and the diagnostic test results in a "Cannot open IO.SYS"
message, then you must contact the original equipment manufacturer
(OEM) for more information. It is likely that the IO.SYS file has been
renamed in the provided version of DOS.
