That kind of low level hands-on programming is not normally permitted
from application code - the OS is designed to prevent it. Preventing
application code from talking directly to the hardware is a large part
of what makes Win32 so much more stable than DOS or Win16.

Instead of requiring/trusting programmers to work out how to talk to
the hardware safely Win32 tries to provide everything they are likely
to need through its API.

Tell us what you are trying to achieve and we may be able to point you
to a developer-friendly API function :)
