I just did this one.
While Apple refused to comment on the issue, the 1.1 upgrade was issued to correct PCI card timing issues and insert code to prevent the B&W from starting with a G4 CPU installed. Heh, 1.1 =was= a fix. Perhaps Apple would rather sell new G4 machines, than allow people to pop an upgrade CPU in their G3.
Anyhow... the folks that provide CPU upgrade kits also provide a patch to remove the G4 block. Pretty simple... run the patch and restart the machine while holding down the "Programmer's Button". You should get a small finder window saying your machine is G4 ready. Install the new CPU, start it up and rock 'n roll!
Bruce (my B&W) is a 300mHz Rev 1 model, running 10.2.8, 1GB ram, with the original 6GB plus a 60GB IDE drive. I just installed an XLR8 MACh Speed G4 Zif 466 mHz and it's working great. (Note: In the B&W machines, the XLR8 upgrades run a little slower than their advertised speed. My 466 runs at 450.)
So... sure you can run a G4 in your machine... just takes a little preparation!

Hi all,
To you old hands at this I'm sure you are tired of hearing it but...what's with the firmware 1.1 not letting you use G4 zifs in a B&W? Was there ever a fix?
I'm on a B&W Rev 2 running OS 10.2.8. Checking the system profiler it says, "boot ROM info 1.1 f4." Does the "f4" mean anything in this context? Will I be able to use a G4 zif in this machine?
TIA, Anand
