   You can get the high-intensity palette by setting the background color
to a high-intensity color (Probably black, that's usually the most common
choice).  To do this, you use the normal BIOS call, INT 10H, with AH set to
0BH, BH set to zero, and BL set to 8 (high intensity black).  Likewise, if
BL is set to zero, you will get the low-intensity pallette.
