Sorry, I hit the send by mistake before finishing. Here's the whole panic message. panic(cpu ) caller 0x002E0EBC) : Unable to find driver for this platform: "PowerBook4,3". Latest stack backtrace for cpu 0: Backtrace: (a series of numbers here) Proceeding back via exception chain: Exception state (sv=0x00r29A00) (a series of equations like the sv one here) Kernel version: Darwin Kernel Version 8.8.0: Fri Sep 8...root: xnu-792.12.6.obj~1/RELEASE_PPC No debugger configured - dumping debug information MSR=00001030 That's the whole message. A guy at freegeek tried to help me, but only could direct me to your list. We tried to reset Power Management, but then found out there was no reset on my model. One time using control/function/shift/power then waiting 5 seconds and powering up, the harddrive logo with two options came up, but then we couldn't get it back after clicking one of them. It just went bakc to the panic state. Hope this helps. Let me know if any more info needed. Thanks again for your help. Wilf -------------- next part -------------- An HTML attachment was scrubbed...
