„I do not own a Mac (yet) but I do administrate some at work and have used this list a number of times. Macs dont have a %u201Cbios%u201D per se but they do have keyboard shortcuts that can kick off various functions during boot. I%u2019ve used the %u201CT%u201D one to boot from an ipod once (I had to install Tiger on a machine that didn%u2019t have a DVD drive).
I%u2019ve found two lists, one for Mac and one for Mac Intel machines.

* C – Start up from a CD that has a system folder
* N – Attempt to start up from a compatible network server (NetBoot)
