EFI: Target Disk Mode, Firewire Booting, Single User Mode - What's the Deal?

59031 · Jan 11, 2006, 04:17 PM

Hold down the T key at start up, Hold down the N key at start up? Command + S at start up and all those Open Firmware commands we know and love..what's the deal now? How do you boot into Single User Mode on the new Intel Core Duo Macs? Target Disk Mode? I don't think this was dicussed at the keynote, was it?

Steve no like getting too technical with that sort of stuffs in those keynotes of he's. Could be the same as PPC Macs, or we might see Ctrl-Alt-Delete added as a hidden feature for developers.

Why would Steve discuss that as part of the keynote? It's not exactly headline grabbing stuff is it. Target disk mode at least has been confirmed.

So Target Disk Mode works, but we have no confirmation on anything else....I don't like that....

This was funny:

"Too bad it's only Firewire 400... wtf were they thinking? And no dual layer DVD burner? And smaller screen res than the previous 15-inch? No 17inch? No Modem?

MacBook Semi-Pro"

Single user mode is a fnuction of the OS (i.e. OSX) not Open Firmware or EFI so that will work too.

This item on the Apple Developer Connection site pretty much says that booting from FireWire (or USB!) harddrives is supported.

Other tidbits--From the online version (PDF) of the iMac (early 2006) User's Guide it looks like:

"Zapping PRAM" is still something you can do as part of troubleshooting (page 81).
You can still hold down the mouse button while rebooting to eject disks (page 85).
You hold down "D" while restarting to boot from a CD (page 87).

What did/does holding down "N" at startup do?

Start up from Network Volume.

P.S. Hold down "D"??? Why would they change that from "C"???

Yeah pretty much everything is still there but their are added bells and whistles. You can boot directly to the AHT now instead of having to chose the drive you mount off of, and you can boot right into the network utility.

Plus the interface is better and more streamlined

USB booting? I want an MBP now! That is totally awesome.

Ah, you might be correct. Though I guess that would count on people not thinking of the hard drive as a disk.

Ctrl-Alt-Delete? yuck!! Don't need that on my Mac! I deal with that almost everyday at work and school on Windows machines. Besides I like Command-Alt-Escape much better as it requires only one hand to do in a much more ergonomic L shape form of the left hand.
