Maybe.  I mean my external (USB) optical drive - also a SuperMulti drive.

I'm playing around with grub.efi on a USB drive as we speak.  I built it as
described here:

 http://grub.enbug.org/TestingOnMacbook

rEFIt sees it no problem and the minimal grub shell actually works!!! :)

When I type 'ls' I get the following:

 (hd0) (hd1) (hd1,gpt2) (hd1,gpt1) (cd0) (cd1)

cd0 is the broken internal optical drive and cd1 is the external drive.

I suppose hd0 is the EFI partition and hd1 the main 300GB (MacOSX) partition.

No idea what to do next.  When I type 'boot cd1' I get a message saying 'no
loaded kernel'?

Needless to say, I'm way out of my depth, but having fun nonetheless.
