I know 2 possibilities:
	1. Switch off all interrupts. In this case all keyboard things
	   have to be done manually by direct keyboard matrix access.
	2. Allocate memory, and tell the I/O, that this should be your
	   video-RAM. (The tios will continue to output busy indicator
	   &co to the normal (dummy) screen, that isn't displayed
	   any more)
