No idea - although I'd _really_ like to have NetBSD on it, I prefer the =
improved performance the new firmware gives me in firewire target disk =
mode.

There's a 2.7 firmware available for firewire equipped powerbooks on asu.=
info.apple.com that looks to support all the same machines as the 4.1.8 =
installer does apart from the Ti powerbook. You might want to give it a =
shot, although I wouldn't recommend it. And I don't really expect the =
installer to run on your machine either.

Is this even when trying to boot MacOS? From a CD? Even the hardware test =
CD?

This could be your out - if the machine seems dead take it back for =
service. Depending on Apple's service policy in your part of the world it =
may have to be processed as a whole-unit replacement, in which case you _=
may_ get a new unit in return.

Along that line, the install docs mention that setting load-base (or is it =
real-base) on OF3 machines will ruin them requiring a return to Apple. If =
you really _really_ can't wait for these machines to become properly =
supported you could kill the 'book that way and try to get it replaced =
under warranty. But I never told you that. Much less recommended it.

Offer what assistance I can in fixing this broken-ness.

If you want to run MacOS, it's 4.1.8 and you get it from asu.info.apple.=
com

If you want to run NetBSD, it appears to be the version that comes =
installed from Apple, and you get it pre-installed. :)
