Nope [since system.ini applies only to 16-bit code]
<<<<<<<<<<<<<<<<

I was referring to the above statement.  SYSTEM.INI began with Windows 3.1 and
was carried over to Windows 9x.  Windows 3.1 is a 16-bit O/S.  Win9x is (mostly)
a 32-bit O/S.  Since many commands in SYSTEM.INI still control Win9x
system-wide, the SYSTEM.INI commands also apply to 32-bit code.

Cheers,
Daniel.
