Keyboard and that damn disc

Learning some stuff about my Mac this morning.

First of all, when in Mac emergency, use the wired keyboard instead of the wireless one.  I tried using the bluetooth wireless keyboard to force bootup (either by press Alt or C) and it failed.  However, using wired keyboard worked even when the wired keyboard was hooked up thru a USB hub.  So that's a good thing.

Second, you can figure out whether a disc is a self-bootable disc by checking Startup control panel and see if it shows up.  If it does, then it's a bootup disc.  Otherwise, it's not.  I knew it because I got a shitty damn so called OSX Lion preview install, but it was shit and didn't show up on Startup control panel. Sure enough I couldn't boot up that disc, and even running the executable on that disc failed.  POC.
