If it has something called CSM, it should be able to boot FreeBSD: http://www.apcmag.com/apc/v3.nsf/0/64E7EA353646669ECA2570F50012430B In fact, Intel has been using EFI on recent motherboards such as SE7520AF2: http://www.intel.com/design/servers/boards/se7520af2/index.htm They didn't say it on the web page but it does have EFI. If the Apple hardware doesn't have CSM, then we have to make 'EFI-aware' boot loader chain and add EFI interface (instead of vm86 bios calls) to i386 kernel. :-( Jung-uk Kim PS: Sorry to bring up Linux here but Linux won't have the problem because Intel has added EFI support for i386: http://marc.theaimsgroup.com/?l=linux-kernel&m=105848983307228&w=2 and EFI LILO (for both i386 and ia64) is here: http://elilo.sourceforge.net/ Just FYI...
