Seem to be a few start-up options in OSX that are key driven. Anyone care to add to this list....

Command + Option + P + R = Reset PRAM
Command + Option + O + F = Open Firmware
Option = Select Startup Disk
Command + V = Start up in Verbose mode
Command + S = Start up in Single User Mode
X = Force OSX to boot up if startup disk was set to OS9
C = Boot from CD
N = Boot from NetBoot Server
T = Boot in Target Disk Mode


Any others.... (any corrections!)

[Edit: fixed the command for boot in OS X]

I dunno what the exact key combo is but: shift-cmd-opt-ctrl will boot you in 'Safe Boot' in Jag.

[Anomalous]

Command + Option + Shift + Delete = Ignore internal hard disk for booting purposes

[Art Vandelay]

Command + Option + Shift + Delete + n where n equals a SCSI ID number will boot your mac from the device at that ID number for Macs with internal SCSI.

wow. Thats a lot of key combos I never knew.

Hold down X to boot to OS X (I don't think you need to hold Opt)

[Geobunny]

To access safe boot, hold the Shift key during startup. The Shift key should be held as soon as possible after the startup tone (but not before). You can let go as soon as you see then grey spinning cogs. When you are booting in safe boot, you will see "Safe Boot" on the Mac OS X startup screen.

* It runs fsck on startup
* It seems to LOAD a minimal set of Kernal Extensions
* It seems to run a minimal set of startup scripts.
* It does not launch your startup items

Click and hold mouse button to eject CD from internal CD drive.

I hear if you hold down every single key it'll boot System 6.0.1.

Seems like a weird feature, but there it is...

is there a combination for stopping login items from opening?

If you hold shift while logging in it should prevent the login items from running. If your machine is set to autologin then you want to hold shift after the machine has started to display the Welcome to Macintosh screen, but before it actually logs you in (the timing can be a bit tricky). If you press it too early you'll do a full safe-boot. If your not set to autologin just hit shift after you hit the button to login.

You can modify the Non-Volatile RAM for the Open Firmware to change the startup behavior. Type nvram -p to see your current parameters.

And then type, for example, nvram boot-args="-v" to always startup in Verbose Mode.

I suspect you can seriously mess up your box this way too, so use with caution.

Great tip on the setting Verbose mode!!

If you do muck up the NVRam you can boot into open firware and issue the following command.
reset-nvram

There is also a reset-all command but I am not entirely sure what that does. During my recent purge of a G4 I did that and it mentioned something about flashing memory before the screen went blank and the system rebooted. I suspect it returns the system to it's default state. The time and date were reset after that.

On my G4 cube, I get the following:

0 > nvram -p
nvram, unknown word
ok

The text at the top reads:
Apple PowerMac5,1 4.1.9f1 BootROM built on 09/14/01 at 13:18:04

Any ideas?

None of those are specific to OSX... they work with all recent macs, regardless of the operating system.

ROFL!!!!!!!!!!!!!!!!!!!!!
