Always boot Mac OS X in Verbose Mode
Booting Mac OS X is attractive and all, but some users would prefer to see what’s going on behind the scenes. Verbose mode shows you what is really happening during system startup, and is great for troubleshooting. Typically if you wanted to boot in verbose mode you would hit Command-V during startup, which brings up the familiar white on black console. If you’d prefer to always see the system messages on boot, you can adjust the firmware from the Terminal with the nvram command.
To turn on Verbose booting, at the Terminal type the following:
sudo nvram boot-args="-v"
Disabling Verbose booting is just as easy:
sudo nvram boot-args=
If you’re curious what the current firmware nvram settings are, type the following:
nvram -p

I would rather just hit command-v when necessary, I prefer the bells & whistles of a nice spunky graphic splash to some scrolling greek text

For those who want to exercise geekdom without satiating their true inner geek, you can do this and a lot of other stuff using a gui util like OnyX. But this is, of course, “funner.”
