   Ditch your fancy new SVGA cards, install an old MDA card, and 
	   mov ax,b800h
	   mov ds,ax
	   mov ax,'eH'
	   mov [0],ax
	   mov ax,'ll'
	   mov [2],ax

     OK, I'm a bit rusty, but you get the idea.

IIRC, the segment base for MDA is 0xb000, not 0xb800 (CGA), but, as
with you, it's been a while.
