I'm working w/ sun support on this issue but still gaining no progress. The bootparams is fine. Replacing the boot image from 10 to 9 works without a hitch, even sees the rules.ok. But for some strange reason Solaris 10 08/07 will not see the rules.ok file. Is there something different about Solaris 10 08/07 that I don't know about? I downloaded a free copy off of Sun's site.
