	I am looking for information on setting a pixel without 
using BIOS calls. Even after setting the following, pixel is not
getting reflected on the screen. My program is in assembly language
and is for a 80386 machine.

	1 Bitmask (mask)
	2 SetReset register( with color)
	3 Enable SetReset register(with planes)
	4 Dummy read before the write



I am trying that for mode 12( Hex) of VGA. 
I am following the method given in the book by Richard F. Ferraro,
Addison-Wesley," Programmers Guide to the EGA and VGA cards.
Can anybody advise me of the possible mistake I am making ? If you 
have please pass on code upto the extent needed for explanation.

Thanks in advance,

Seshu
