David Brownlee writes in repsonse to Craig Beasland:
 > 	Your NVRAM is dead, and your ethernet address has been set to
 > 	'all ones', which coincidently is the ethernet broadcast address.
 > 	SunOS and early version of NetBSD use this value without testing,
 > 	which, although convenient in some cases, is Just Plain Wrong.

 > 	You will need to plug in some values using the PROM - see
