Re: Booting FreeBSD 10 from grub on Solaris 11.1 (grub 1.99)

[address@hidden]

Hi,

  If you can try this from qemu, you can get down to the machine level to 
figure out what's going wrong.  Booting FreeBSD is something we never really 
tested unfortunately but if there are issues that perhaps existed in the trunk 
at the point we forked grub for Solaris, we might need to add some patches. If 
you can help to figure out which those are, I'll get those integrated.  Sorry 
about the inconvenience!

  Thanks,
  --S
