Trouble Booting: Open Firmware error, blank screen, frozen gray screen, etc
So I got the "To continue booting, type 'mac-boot' and press return" message today when I started my computer.
I restarted and reset the PRAM.
The message still appeared after I reset PRAM so I reset the Open Firmware settings by typing "reset-nvram" and pressing return and then typing "reset-all" and press returning.
The computer restarted but still came to the "To continue booting, type 'mac-boot' and press return" message.
That's when I noticed this at the top of the screen:
DEFAULT CATCH! code: fffffff6 %RR0: ff80b260 %SRR1: 0000b030
I think I wrote all of it down correctly. 🙂
I had a mouse attached when the problem occurred the first time. I removed the mouse and restarted the computer.
The next time I started up the computer all I got was a blank (black) screen. I could hear the harddrive on, but nothing showed up on the screen. Shut it down by holding in the power button, started it again, same result. I shut it down again, held in the little reset button on the back, and started it up again and this time it worked.
A few start-ups later, I got the grey Apple screen but it froze there. I restarted and got the same result as described above, and followed the same steps as above to get started up.
Suggestions? 🙂
