Code in the boot rom.  Plus, they likely do much more.  YAMON does lots
of board specific initialization, so when porting Linux to an Au1xxx 
that doesn't
use YAMON, you are going to have to add to the Linux initialization 
functions
for the board.  U-Boot is a popular boot monitor that is now finding 
it's way
to the Au1xxx processors.

Yes, they usually do that.
