Presuming you haven't updated your firmware with Apple's 4.1.7 or
4.1.8 OF patch.

(Which, apparently, will also get you disappearing RAM if its even
slightly out of tolerance--or just doesn't know how to operate at
CL-3, and, on some machines, make your CD tray eject, even if empty,
on every reboot.)

Is it only the tiBook where we have these problems, or does that
firmware version cause problems for desktop G4s too?

(It'd be nice if our FAQ were a little more clear about exactly
what the deal is with Apple's wacky firmware update scheme.)

So are there one or two different iBooks in the above?

The iBook2/iBook (Dual USB) is the new white model, right?

Is the iBook (Firewire) an old(er) clamshell iBook, but with
firewire? (If so, why aren't we calling it the iBook1.5. ;^>)

Also, ADB really *is* working on all machines now? For sure? Bob
Nestor says (on port-mac68k) that it's broken in -current for
certain mac68k machines and was wondering if that breakage was
releated to the B&W macppc breakage. Is it, instead, perhaps related
to the fix for us? (Is ADB support even in the architecture
independent branch? It really should be... at least next68k can
probably use the same stuff too, on ADB-based machines, at least.
And the nebulous, not-yet-extant ppc-without-OF port would be able
to too.)

I think all you can do is be noisy in INSTALL itself that it realy
does work for the 1.5.1 release, as long as we remember to change
that again should the situation change again.

I'd say that's a good idea.
