nanobsd image

[Jack Mc Lauren]

hi all
the last problem solved! But i can run one of our systems  with nanobsd image but on some of them i can't and i have the following error :

a black screen with some messages like :
If you have invalid mount options, reboot, and first try the following from the loader prompt :
set vfs.root.mountfrom.options=rw
and so on ... 


Are there any options which may cause this problem and make this difference ???
