If you have one of these new macs, or know about EFI, can you tell us if they still have a bios and EFI or is that replacing the bios and the bios gone completely?

Nevermind, I found the answer when i was searching for linux distro that has grub2 already on it,



"Trying to translate the above into plain English, the main problem with MacBook Pro is that it no longer uses BIOS (Basic Input/Output System); instead, it ships with the new EFI (Extensible Firmware Interface), developed by Intel, to perform all the early communication between different hardware parts. Although EFI does have BIOS emulation support, Apple has reportedly decided to remove it from their MacBooks.

The second issue is GPT (which stands for GUID Partition Table, with GUID being an acronym for Globally Unique Identifier), which is effectively a replacement for the MBR (Master Boot Record) in EFI-based systems. Among the popular boot loaders, neither LILO, nor GRUB 0.9x support GPT, although the new GRUB 2 (currently in alpha development) does include support for the new standard. Unfortunately, not a single Linux distribution has been bold enough to switch to GRUB 2, but it is possible that more effort will go into this area in the coming months, especially if EFI-based motherboards become widespread.
