>Environment:
System: NetBSD priscilla.hhhh.org 1.4.2_ALPHA NetBSD 1.4.2_ALPHA (GENERIC_MD) #0: Fri Dec 24 19:36:10 JST 1999 tsubai@mint.iri.co.jp:/usr/src/sys/arch/macppc/compile/GENERIC_MD macppc

>Description:
		When attempting to boot an iMac from a working i386 NetBSD bootp
		server, it fails its boot probe with the following messages
		(from jotted notes):

		NetBSD 1.4.2_ALPHA (GENERIC_MD) #0: Fri Dec 24 19:36:10 JST 1999
		tsubai@mint.iri.co.jp:/usr/src/sys/arch/macppc/compile/GENERIC_MD
		CPU: 750 (Revision 202)
		real mem = 134217728
		avail mem = 120975360

		trap type 200 at 275f60

		db>

>How-To-Repeat:
		Netboot an iMac.
>Fix:
		From browsing the mailing lists, it looks like this problem can
		be taken care of by adding a DELAY() somewhere in the bootstrap
		code.  This solution does not seem to have made it into the
		netbsd-1-4 branch (at least it hadn't as of the Dec 24th build
		date).  Perhaps a newer -current snapshot might also be in order?
