I just noticed that SRM 6.0 had a timeout problem when booting from my Aspen Alpine (EB64+) whereas the same SRM 6.0 worked OK booting from my K6-2 box. This leads me to the suspicion that there is something *very* timing critical (or something close to that) on the later SRM revs. Chris, as I understand it you had NetBSD booting using bootp from SRM. Or did you use MOP maybe? IIRC NetBSD can do MOP boot serving. > "stupid, stupid, stupid."
