Re: Installation on Macbook Pro
Here is a little update for my problem...

IIRC, you need to fiddle with ad5*. A better alternative I can

installer first, then boot with DragonFly LiveCD, and continue the

Formatting with FreeBSD worked fine. FreeBSD appeared to have
formatted the disk differently by switching the slice order. So the
165 ID (DragonFly/Free BSD) slice came before my 175 ID (HFS+) slice
even though the physical disk layout was the other way round
(Significant at all?). I now had a properly sliced drive so I rebooted
with DF which could now write to the disk :). Thank you for that,
So I rebooted and this time booted from the hard drive. Boot loader
came up! Unfortunately, it couldn't boot the DF slice. So I went back
to the CD and (this is where I got a bit stupid...) fired up fdisk to
check everything out. Nothing to odd. Had a look at gpt's output too.
Which I found to be a little odd. The DF slice shared the same index
(of 1) with my EFI slice with Mac OS X at index 2.
Let me first explain that, from what I read, in order for a computer
to comply with EFI they have to have an extra slice set aside for EFI.
On my laptop that means that I have this in the form of a 200MB slice
with the rest for whatever. Now I remember seeing when Mac OS X and
Windows was installed, I booted into the DF live CD and ran gpt. The
output that time around was EFI slice at 1, Mac OS X at 2 and Windows
at 3. Even though I don't think boot0 can boot from the GPT, I wonder
whether the FreeBSD installer changed something in a similar way to
the MBR. Very speculative, I know but I can't check out anymore
Going on my hunch that something in the MBR was wrong and was causing
boot0 to not read it properly I decided to open up fdisk and see if I
could find anything that might be a cause. I checked each slice
through using the -u option (IIRC) and when I got the the Mac OS X
slice it complained about the head boundaries being all wrong. I
rather stupidly thought that I'd let it automatically update this.
This caused nothing to boot etc. Long story short I ended wiping
everything in favour of it being quicker for me (I had deadlines to
meet...). It was all backed up so hopefully that won't keep anyone
awake at night!
I think I will come back to DF in the not so distant future but I'm
just going to let myself go on other things for now. Thanks a lot to
all you guys who tried to help me. I really appreciate it :)
P.S. Would it be possible to by pass the MBR all together in favour of
GPT by simply using another boot loader other than boot0 or would this
also require changes in the kernel or elsewhere?
