	Some notes should be made here:

	ethdev.sys is about 6-7K plus user defined buffer space.
		In the numbers above, the user has selected 20K of
		buffer space. We find that most applications can
		run with about 10K of buffer space. This reduces the
		memory require to 62,352.

	Also there is an error in the number for TCPIP.SYS, the actual amount
	of memory required is 15968 bytes reducing the total bytes by 3888.
	(it should be noted that when driver sizes are calculated, the last
 	 driver loaded in config.sys usually has an incorrect size associated
	 with it. I always load ansi.sys last in my config.sys to determine
	 the dirver sizes).

	Thus the size for the above configuration is: 58464 bytes. This
	number is also dependant on the particular ethernet adaptor used.
