The installation program looks for Windows. By creating "Windows" and
"WindowsSystem" folders, and "fake" system.ini and win.com files, it can
be fooled into working.
From DOS, type:
COPY CON SYSTEM.INI
(type some random text to continue)
(you will see "1 file(s) copied")
COPY CON WIN.COM
(again, type some random text to continue)
Installation should now run smoothly. If you plan to install Windows, be
sure to remove the fake Windows directory.
