	Hello, 
	I am currently writing a graphics library that only has one 
graphics resolution. Does any one have any C code to change the resoulution
of the VGA card ? E-mail would be appreciated.
		Thanx in advance.

 Sorry, but mode each mode has only one resolution - a graphics mode is a 
definition of resolution and number of colors. To change the resolution you 
have to change the video mode (e.g. 12h is 640x480x16, 13h is 320x200x256, 
for better resolution and higher number of colors you have to use VESA 
modes).
