I'm developing an application that uses an EGA to do 16-color 640x350
graphics.  I also have text on the screen, and need room for more (more
lines).  [I'm using MSC 5.0] 

I get into graphics mode with:
	_setvideomode(_ERESCOLOR);
This gives me a nice 16-color 640x350 graphics screen, and I have 25
lines of text on the right side of the screen.  Needing more lines, I 
use Interrupt 0x10,  function 0x11, subfunction 0x23, with BL=0x03.  
This selects the 43-line-mode font (8x8 pixels per char instead of 8x14).

My problem is that I can't '_settextposition()' to get to lines below
the 25th.  I'm pretty sure I need to tell the EGA bios to recompute the
number of rows, but I can't find the info on how to do that anywhere...

Thanks in advance for any help...
