Occasionally, NetBSD refuses to boot on my AV Mac. Is there a remedy?
Yes. You need to zap the PRAM by holding down Command-Option-P-R while booting into the MacOS. For some reason, the AV Macs (i.e. Quadra 840AV and Quadra/Centris 660AV) are more susceptible to this problem than other classes of machine. However, zapping the PRAM seems to cure most of the problems. Thanks to Dave Huang (khym@bga.com) for this information.
