That's why we need to write another installer for installing Win95 on top 
of opendos when and if it works. There shouldn't be any problem with 
IO.SYS (which BTW is like an INI file) because opendos calls it 
IBMBIO.COM. A special installer that wouldn't install MS-DOS 7, but would 
install any special drivers required for opendos to boot would be 
nessecessary.
