Narendra, Please check out the BigAdmin tech tip (linked above), which spells out the step-by-step procedure.
Essentially, I added sun4v group-specific packages (all ending in *.v) from the DVD, to a sun4u system. Then, I tricked out the flar tools, so the resulting flash image lists both platform groups. Feel free to try it yourself, however be aware that this is not Sun supported. I don't know what patching or upgrading might do with such a system image. Thanks... -cheers, CSB This message posted from opensolaris.org
