   Not in the J90.  The J90s SPARC5 connects to the IOS processors via 
ethernet.  The only "extra" thing in the SPARC5 is a secondary ethernet 
interface, which is an unmodified Sun board.  The IOS SPARC5 processor 
(or processors, up to sixteen) netboot their loads (which is *not* 
SunOS or Solaris) from the console SPARC5.
