EFI still uses a MBR though I think the format may be slightly tweaked. The EFI loader is stored in a FAT32 slice in fact, which is why there was a discussion on -ia64 recently of whether or not /boot should be a FAT filesystem. I think to maintain compatiblity with multibooting other OS's we shouldn't really claim the FAT fs, but simply let the base EFI loader load up a EFI-capable loader from FFS and boot from there, but that is another can of worms. :) -- John Baldwin <jhb@FreeBSD.org> -- http://www.FreeBSD.org/~jhb/ PGP Key: http://www.baldwin.cx/~john/pgpkey.asc "Power Users Use the Power to Serve!" - http://www.FreeBSD.org/ To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe cvs-all" in the body of the message
