Screwed Up a Sonnet G4 ZIF Install

[spincast111]

I just installed a G4/800 ZIF processor into my B&W and it freezes on startup.

Now here's the kicker...I skipped the part where you install the OS X software before restarting OS 9 (OS 9 software was successfully installed w/ BIOS update) then I switched to OS X using the SYstem Preferences Startup Disk panel. I assumed the OS X tune-up needed to be installed in OS X. Now when I turn the system on I just get the grey screen with the Apple and no progress wheel.

I figure I need to restart into OS 9 somehow. Can't boot CD. Can I change the boot flag somehow, maybe from onther system? ie Pull the drive and do it in another system.

Thanks.

Hold down the option key at startup. You should then get a choice of System folder from which to start up. If that doesn't work, why don't you just pull the ZIF update, put the original processor back in. Then boot into 9 (or even X) and install rest of the software.

Fixed it.

The problem with Sonnet upgrades in B&W is that you can not boot from an OS X CD. The option key startup also does not work, and I was flagged to boot into a non-working OS X, even with the old CPU back in place.

I thought the no CD boot, was for all CDs. Turns out I could boot from an OS 9 CD. I installed the proper software, and everything works fine now.

Thanks for the suggestion though.
