any options that you set remain in effect
until you change them again.

When you start Windows, it consults the
system.ini file to determine a variety of
options for the Windows operating
environment. Among other things, the
system.ini file records which video, mouse,
and keyboard drivers are installed for
Windows.
Running the Control Panel or Windows
Setup program may change options in the
system.ini file. On other occasions, you
may need to change or add options to the
system.ini file manually with a text editor,
such as Notepad.

less it is the last device in the series.
However, some devices have terminators
that should never be removed or disabled.
