Thanks for quick and correct answer from some many people. Most people give me
following answers:

 1. Try "boot -r" --- it did not fix problem
 2. Sparc 5 and 20 are different architecture and can not do it. -- both acturally
are same structure (sun4m)
 3. The device tree are different and need extra work. -- it work, see
attachment.
