Indeed : http://removers.free.fr/wikipendium/wakka.php?wiki=Super%28%29
But the thing is, you only need to go in supervisor mode when installing your $70 routine. Once installed, it will be executed in supervisor mode because $70 is an interrupt vector.
So you could simply use the XBIOS Supexec(my_installer_routine). See: http://removers.free.fr/wikipendium/wakka.php?wiki=Supexec%28%29
But you actually need not go supervisor to set-up some vector. Sounds like you only need to call the Setexc BIOS function like this: Setexc($70/4, my_vbl_routine). The simpler solution, by far.
See http://removers.free.fr/wikipendium/wakka.php?wiki=Setexc%28%29

What's the anti-troll code?
That's your personal code to be able to add comments and messages on the dhs.nu site.
Don't have a code or forgot it? Fix it here.
