To my chagrin I have discovered that the "fast-video" routines Turbo-C
uses are not fast enough for my needs, so I'm writing my own. Here's
what I think I have to do:

	- find out if the display is monochrome using BIOS Int. 11
	- if so, display starts at B000:0000
	- otherwise, display starts at B800:0000
	
Are there any hardware combinations where this _won't_ work? In other
words - are there any common display adapters that have their video
memory elsewhere? and is Int.11 reliable?

Yes, I know about snow; I will give users the ability to switch on
snow-protection.

Thanks in advance,
