 	   4 are used to identify and configure the board. With the advent of PnP,
 	   these first 4 addresses have become obsolete, and software applications
 	   only use the last 4 addresses to control the codec chip. Therefore, the
 	   base address setting "skips past" the 4 unused addresses.

	A. WSS I/O requires a block of 8 I/O addresses ("ports"). Of these, the first
	4 are used to identify and configure the board. With the advent of PnP,
	these first 4 addresses have become obsolete, and software applications
	only use the last 4 addresses to control the codec chip. Therefore, the
	base address setting "skips past" the 4 unused addresses.
