Ok thank you. But actually, it's not what I'm looking for.
I use freebsd on a macbook. On this macbook, I already have a gpt,
refit, mac os x and some linux partitions. The problem is freebsd, which
doesn't recognize partitions after the fourth one (but my gentoo linux
Then, I suppose freebsd use the mbr partition table (synchronized from
the gpt one using refit) to populate the /dev, but partitions after the
fourth, which are those I want to use, are only indexed in the gpt.
Finally, I want to force freebsd to use the gpt on my hard drive to
allow it to see others partitions.
I don't want to destroy my actual gpt, maybe one day, but no right now.
Tell me if my english is too bad to be understood.
I just want to precise that I use pcvbsd 7.0, so the kernel
configuration might be different than the freebsd generic one.
Thank you for your answers.
