ring0 access

ring0 access

[Jason Roberts]

I have a desire: switch cpu context to real mode from pm
I have written really cool music that works through BIOS--
unfortunately, the only way I can get it to work is through
a bootsector,i.e.hook code before OS boots--
is there any way at all possible to use interrupts, set up my own
handlers, or do any real direct hardware access through
32-bit mode,i.e. while in running KDE or Gnome???
Appreciate any advice...what would really be nice is
a cool set of functions like : enter_ring0() ... back_to_pm()
Thankyou,
Paul

Paul,

    Have you got any answers to this question?... I am very curious too,
but i really believe that is not possible; pm would be few meaningless if
that was....
