Startup key sequence to enter EFI
The open firmware startup key sequence [cmd] [opt] [O] [F] does not enter the EFI equivalent on the Intel iMac. What is the key sequence?
Thanks!
Thanks!
15 inch Intel iMac, Mac OS X (10.4.4)

No. What they did was boot into an Intel EFi test interface that they downloaded and installed. The Mac EFI still has no user accessible interface.
Careful messing around with that. Several people have already hosed their new iMacs beyond user repair by throwing commands at the EFI firmware.
Once you break it, you are done. You can't zap your PRAM or NVRAM if the firmware that listens for those keys at startup never actually comes up. =( You are just hosed for good at that point.
When my MacBook arrives, I will not be messing with this sort of thing at all. I value my money too much to have a $2000 paperweight.
