 In order to complete this process, you will need the following from the
 `OSREV/hp300' directory of the distribution:
 
 	SYS_UBOOT	The unified boot block file.

 To boot SYS_UBOOT via the network, you will need a system capable of
 handling boot requests for an hp300.  If you will use this method, see
 the special note below.
