Hey Everyone,

School and work have impeded my progress. Still not booting, but it's coming along, albeit slowly. I have already emailed Sergey (forgot to cc bug-grub) and hopefully we'll be able to work together to bring this about before 5 goes stable (which should give us plenty of time =)

Hi Sergey. Thanks for your interest on GRUB, we really need help from *BSD

FYI. Grub can't download FreeBSD 5.x because it doesn't support UFS2.

We are aware of this. Chris Reichow <chris at reichow dot net> was working
on that but he hasn't reported any results so far (I'm CCing him).

His initial post has some UFS2 info you might find useful:

Unfortunately he didn't release any patches we could use. If you can help with
UFS2, that'd be much appreciated.

I tried to write support for it, but I don't know how to debug it.

When I use printf in ufs2_mount for debugging it damage booter and it reboot continuously.

I suggest you use Bochs (http://bochs.sf.net), the i386/PC emulator. Bochs
has a built-in debugger but you can also attach a GDB stub to it (see the user
documentation). I haven't tried the GDB/Bochs/GRUB combo myself but you should
be able to debug GRUB with symbols through GDB.

Can somebody write ufs2 support or may be consult me strongly?

I'm afraid I don't have time currently to work on this, but if you have
questions on GRUB internals just ask, probably someone in the list will help.

Do you have any unfinished patches? If you do please send them to the list I'd
like to have a look.
