Personally, I would follow Sun Microsystem's (and now Oracle's) procedure.
 Or, at least, your Sun support vendor.  SunHelp won't come to your shop and
fix it if it doesn't work.

Sun Microsystems does not approve of the above method.  They explicitly
discourage doing this NVRAM hack in their hardware support courses.  Sun
Support or your Sun support vendor can provide a working NVRAM chip if the
server is under contract.
