Comment 137 for bug 576601

Hey Jan,

I couldn't get it to boot without MacOSX installed. I just resized my MacOSX
partition to something like 15GB in size and left rEFIt for what it was. It
works well enough like this although I'd love to see more EFI support soon.

Cheers,
K!

> Impact: SATA drives on the MBP 7.1 are not usable as the ahci mode is not
> working correctly.

> Fix: Two patches taken from upstream, which have also been marked for

> Testcase: See report. Disk drive not usable without the patches.
