The FreeBSD partition fails.
Unfortunately, I get the same error as what I met when I was using the
FBSD admin MFS. This time, the grub loading is successful, it can
recognize the FreeBSD partition, but...kernel loading still fails.
Please refer to the attached "Grub load Freebsd6.4 under Linux Admin
MFS.JPG" as grub boot reorganization and the "boot Freebsd6.4 error
under Linux Admin MFS.JPG" as the error message.
The Linux partition booting is successful.
By the way, do you have a FreeBSD7.x version of generic image in Utah?
Because I have tested to install a standard FreeBSD7.2 into disk from
official distribution, and load it under both FBSD MFS and Linux MFS,
both loading succeed. But the FreeBSD6.4 does not. So I wonder if this
is a deeper bug in the version of OS, not MFS. Just guess...

Thanks. I'll take a look at this later tonight to make sure
everything looks sane.

Ah, right. I forgot about all that. Sorry. Anyway, here's how to
boot a partition manually:
1. Reboot the node and watch the console for the message 'Press ESC
for GRUB menu'. When it appears press ESC.
2. When the menu comes up press 'c' for a Grub command line.
3. At the command line, enter the following commands ('x' is the
partition number you want to boot):
set bootinfo.orig_root=hd0,x
bootinfo_magic
boot
This uses some code we added to Grub to automatically figure out what
kind of partition hd0,x is and how to boot it. the 'bootinfo_magic'
command should display some output detailing this information. If
things don't work as you expect you could send me a screenshot of
this.
I realize that currently this is a bit more awkward than typing
'part:1', but it'll hopefully be simpler soon.
I'll be in the office tomorrow, so let me know if you have any more
problems this weekend (if you're working this weekend, that is). Glad
that we've got this (nearly) working for you.
