[求助]什麼是EFI （Extensible Firmware Interface）可擴充韌體介面？

想說用了Intel的CPU
是該要多了解一下硬體的時候了 （玩那麼久的Mac還是硬體白癡）
找到了些有用的Intel中文官網的CPU core dual資料

剛好看到 一個新軟體叫 rEFIt
http://refit.sourceforge.net/
rEFIt is a boot menu and maintenance toolkit for EFI-based machines like the Intel Macs. You can use it to boot multiple operating systems easily, including triple-boot setups with Boot Camp. It also provides an easy way to enter and explore the EFI pre-boot environment.
