How to know if my BIOS supports UEFI?

Just watched the Win8 keynote thing, and seemed like the fast boot times required something called UEFI(?). What is that? How do I know if I have it? And if I do have support for it, do I have to do something to enable it, or is it "already there" sort of?

If you do not have it there is no way to add it. –  Moab Sep 13 '11 at 20:06

This is the successor of the good old BIOS.

Many modern servers already have UEFI, there mostly resulting in longer boot-times. Mac-systems (with Intel-Processors) also rely on UEFI.
