System: NetBSD 1.6_BETA4 NetBSD 1.6_BETA4 (GENERIC.cs20) #0: Tue Jul 23 00:31:11 CEST 2002 alpha
Architecture: alpha
Machine: alpha
	The NetBSD/alpha netboot code fails.	Attemts to use it on
	an Api CS20 resulted in:

P00>>>boot eia0
(boot eia0. -flags 0)

Trying BOOTP boot.

	I also hear that Nathan Williams has experienced similar
	lossage on a recent install of earlier NetBSD/alpha beta

	Try to netboot an alpha system using the 1.6_BETA4 netboot
	binary, watch it fail.

	A possible workaround is to use the netboot code from either
	1.5.2 or 1.5.3.

	Sorry, don't know how to fix this properly.
