Using EFI firmware in Linux guest

HI Community,

I'm using Fusion 5.0.2 and I try to create a Linux guest (Debian 6) on a EFI based VM. I added the line firmware = "efi" in the vmx configuration file of the guest and got an EFI prompt while starting the VM but the system stopped on that EFI-prompt.

Clik here to view.

What I've to do to get this setup working?

Thx in advance & Bye Tom
