Is it possible from ring0 access change masks via 21h and a1h ports
to dissable devices assosiated with bit flags and prevent windows change
values in these ports after terminating from ring0

Ring 0 is kernel mode code execution which i mean to say OS ( Windows ) and other VxD's runs in that mode.

And in this mode you can very well read or write anywhere in memory or port but with care because a single instruction make you compu hang!!!
