#		01 ==> 4 bits/pixel
#		10 ==> 2 bits/pixel

#	In 1280 mode, Zoom must be set equal to BPP.

#	Depending on the monitor you need to set the kind of sync.
#	This file is for an NEC Multisync type monitor which supports
#	CS (composite sync) so, bit B must be turned on and bits
#	A, 9, 7 must be turned off.
