I'm having the same problem with the dvd rebooting soon as it begins to load. but Zephyroth's 10.5.1 amd, did work for me just couldn't get the diskutil to partition my SATA HD. it could see it and display info about it, but couldnt modify it. any help would be great.

what is EFI, i know it has something to do with BIOS and booting. is it something i have to install or change my partition to BEFORE trying to boot this DVD?
