In the process of configuring an old G3 all-in-one running OSX, I've
lost the ability to boot up from the hard drive.
The drive has OSX installed, and was booting OK. I had a few problems
with icons not showing, but updating to the latest 10.2.x seemed to cure
that. I cleared out some old accounts, and for tidiness sake I also
zapped the PRAM and then tried to do an open firmware reset. Which is
where my troubles began. CMD-OPT-O-F gave me nothing but a black screen.
I rebooted, and now the hard drive refuses to load the system.
