>Release:        FreeBSD 2.2.1-RELEASE i386
>Environment:

	Pentium with SMC Ultra Elite at I/O address x240, IRQ 11,
	memory buffer at xC8000

>Description:

	The 2.2.1 kernel configuration editor has mysteriously the
	ability to edit the third parameter required for the ed0
	device, namely the memory buffer address.  This loss of
	function, which was available as late as 2.2, is a step
	backwards.

	Note that since some drivers (OS/2 NDIS) automatically read
	the card for the buffer address, the loss of the buffer
	address from the editor might imply to the naive amongst
	us that the value is automatically determined.

>How-To-Repeat:

	Attempt to boot a machine with the install floppy for network
	installation.

>Fix:

	As a work-around, install from local media and then regen kernel,
	or reconfigure card to conform.
	
	Back out whatever change dropped the buffer parameter from the
	kernel editor.
