You are welcome. You may run into another G5 (PowerPC64) problem that I've not reported = because I've so little evidence and it has been very intermittent. Also = it is a normal boot issue, not an installation-media specific issue. Normally one goes through open firmware and either types boot or one = lets it autoboot (explicit return or timed out) and the screen changes = to black and the white text starts to show up, starting with the = copyright notice. But some of the time on the G5's it instead hangs after going black but = before any part of the copyright text shows up. This has happened on all = 3 G5's, two being 7,11's (NVIDIA video) and one being a 7,2 (Radeon = video). The fans gradually wind up when this happens. (Unlikely if only = the video display was messed but it actually went through the normal = steps otherwise.) I've had a wild mix: At times I've gone bunches of boots without the = problem. On rare occasion I've had to reboot up to a dozen times to = finally not have it hang. Normally once the problem happens I have to = retry at most a few times. [I do not have access to a single-processor PowerMac G5 system. So I can = not compare/contrast behavior with those. All my PowerMac G5 notes are = multi-processor G5 notes.] =3D=3D=3D Mark Millard markmi at dsl-only.net On Jul 26, 2014, at 11:40 PM, Nathan Whitehorn <nwhitehorn@freebsd.org> = wrote: Interesting.
