I'm guessing it's telling you your PRAM battery is dead, or nearly so?
That's entirely possible, given that I've reset the PMU 3 or 4 times,
which drains the battery, right?
After further research on PMU reason code -122, it came to light that
*external* power considerations might be causing an issue. So I
unplugged the G5 from my power strip, and hooked it directly into the
wall in a different outlet. I was then able to boot from whatever
media I like, with whatever disk in the drive I like. I was also able
to rip and transcode a DVD without any problems. So the problem seems
to be either a) the circuit is overloaded (it has 2 other PCs on it)
or b) my power strip is bad. Either way, it's a lot cheaper to deal
with than a new PowerMac PSU.
Does anyone happen to know what the power draw of a dual G5 1.8GHz is
under full load?
