I'd be glad to get it to boot off a USB stick or from network, but I can't get it to to that, either. Whatever I do at boot time, it just boots straight into the nstalled MacOSX. I tried to set the startup disk in Preferences > Startup Disk; but unlike the MacOSX install CD, which appears there as an alternative, the OpenBSD install CD does not. I also tried installing NetBSD on it, with the same non-result.
