You can't use uppercase "U" in your open firmware password on most modern macs. Lowercase "u" and anything else is fine apparently. How weird is that. Not that it matters, who is using it anyway? Except to clear the nvram and as a poor mans System Profiler I haven't even booted Open Firmware since '97 when you had to do odd hacks to boot Linuxppc.
(Hold down command-option-O-F just after turning the computer on to boot into Open Firmware; it's fun! Programmable in Forth and all.)
Ah, you can set the password with a nifty tool. Brave new world.
PC Magazine are reviewing the giant 17" laptop I made fun of a while ago. "Pushes the Limits of Portability" they say. I thought even the 17" Powerbook did that! I need to stop mentioning powerbooks in every entry I make here.
