DOS interrupt 10 is the software interrupt dedicated to Video BIOS.  The 
trap vector executed when the interrupt is called depends on the value(s) 
stored in other registers. To set the video mode,  you set the high byte of 
AX to 0x00 and copy the desired mode into the low byte of AX. I suggest that 
you check out Ralph-Browns interrupt list:
            http://www.ctyme.com/intr/rb-0068.htm
I am not sure if there is a standard mode that supports 256 colors in 
640x480, so you may have to consider a tweeked mode......
