Further exciting 😉 EFI news.
[Option] still brings up the boot chooser. Sparkly big (really big) new icons.
[N] still netboots (Big new globe icon)
[C] does CD/DVDNot sure about any of the other keys.
Also – how do you set the “open firmware password” to stop the user doing the above?
Was on the floor at Macworld and spoke to one of the Apple people huddled protectively around the new iMacs – while the Help Viewer docs still say Command-Option-O-F, he told me that you access EFI while holding down the “X” key at boot.
Of course, he wouldn’t let me try it (“can’t reboot these iMacs on the floor!”), but I’d love to see what it looks like.
The OS X Security session Apple presenter told us that the EFI interface doesn’t look too different from Open Firmware – “don’t look for anything too new or shiny in there” – and confirmed that NetBoot and NetRestore work BETTER with the new firmware.
Anybody had a chance to actually look at this?
Went to Durham, NC Apple Store and they did not have nay out according to the clerk. They said sometime next week they would stock/sell/demo the new iMacs. I will try this and report back.
There is no EFI shell on the new Intel-based Macs.
Firmware password can be set by the new password utility included on the system media with the Intel-based Macs in /Applications/Utilities, which supports Open Firmware as well as EFI passwords.
All normal boot modfiers work:
C – boot from optical media
D – boot from diagnostic partition (Apple Hardware Test) (new)
T – target disk mode
opt – a new Startup Manager
F1 or N – network boot
cmd-S – single user mode (before which an EFI console screen is briefly present)
cmd-V verbose modeThe X key does NOT boot into EFI.

http://das.doit.wisc.eduApparently, the iMac prototypes allowed the use of the X key to boot into an EFI shell, but this does not work on production models. Also, there appears to be no EFI shell included on the production machines.

actually…
C – boot from optical media
D – boot from diagnostics on optical media if present (Apple Hardware Test) (new)
There isn’t a separate partition for this
T – target disk mode (Firewire)
opt – a new Startup Manager
F1 or N – network boot
option-n – netboot from the netboot server’s default imagecmd-s and cmd-v are both part of the OS X booter, not EFI…
From the terminal:
sudo nvram boot-args=”-v”
will enable verbose booting on the new Intel iMacs.
