| Did you upgrade to Leopard?
That's what screwed my Firewire on my iMac G5. I strongly suspect one of the firmware upgrades along the upgrade path to 10.5.2.
What's even worse is that I can't downgrade to Tiger, boot up off my old Tiger DVDs nor get it to boot into Diagnosis mode.
I have done a complete clean install and an archive and install, zapped the PRAM, booted into safe mode etc. Nothing works. |
