Sorry, I already believe that like taking the system installed in the Compact 
Flash:

In psbdboot. 
* kernel name: /netbsd
* Frame Buffer:Mobilepro 780 
* Options: - b=wd0 
it makes the mapping of the memory, begins to read and when appears "execute 
kernel " it stops.

The system I believe that this installed good, I have at least not seen 
error message. 
Some suggestion,? He is correct what I make to take the system? 

Thanks.
