hi all,

i installed my rev1 amd version dvd to a internal sata connected through sb600 chip from ati.
i tried it already with mbr and now i'm on guid.

after reboot the system shows a blinking cursor and do nothing. i can access my system only from booting with dvd and rd=diskXsY .
what is it? i tried to install efi but it didnt work. 2 weeks ago i successfully installed the same rev1 dvd on a external usb2.0 hdd on the same machine!
and after intallation i could successfully install and config efi ! and everything worked.

whats the problem with efi now? can someone help me please. and to zeph: best mac release ever! keep up the perfect work with your team.

specs:

amd x2 am2 3800+
msi k9a platinum with sb600 southbridge
4GB ram
3 satas internal
