A friend of mine accidentally played with my unit (actually a iMac DV 400se). This is what he did: - pressed down the programmer's swtich while pressing the power on switch. >From my understanding, this is only used for updating firmware. But the thing is, there was no firmware file update loaded. It did work. After typing reset-all the OS boot properly to OS9. But after I restarted the unit, the open firmware came back with the terminal window. I type "reset-all" again..but now, it doesn't want to boot properly anymore. What are the causes? Defective motherboard? Ram? Brian Michael Lim Principal / EchoGrafika Brian, When this same thing happened to me, I was advised to zap the PRAM. Once I did that, everything went back to normal operation. __________________________________ Dwight Cendrowski Dwight Cendrowski Photography LLC 2870 Easy St Ann Arbor, MI 48104-6532 Voice: 734 971-3107 Cell: 734 330-5230 Fax: 734 971-9232 e-mail: dwight at cendrowski.com web: http://www.cendrowski.com
