Install newest firmware prior to 10.2 update
Authored by: loucks on Jan 13, '04 10:27:59PM

IMac firmware fix:

So you tried to install os X 10.2 without updating your firmware to 4.1.9 and now you don't have any video…. and to top it off you have a 350 with no DB15 vga connector. Well here's what I did to fix my iMac.

First I removed the hard drive from the iMac and plugged it into my G3 B&W tower.

I loaded a clean install of OS 9.1 and downloaded VNC (chromatix) and the updated firmware (4.1.9)

I installed a VNC Server(chromatix) and copied it to the startup folder so it would start everytime I booted the iMac.

I put the hard drive back in the iMac and booted it up.

I VNC'd into the iMac with my powerbook and ran the firmware update.

I shutdown the iMac and turned it back on with the programmers button held. Released when the long tone sounds. The iMac did the firmware update and made the startup sound a couple times. I then powered off the iMac and Zapped the PRAM (hold command option P R and I held it for 3 cycles). Let go of the keys after the third cycle and WOO HOO I got video again and the computer boots and tells me that the firmware update was successful.
