No you cant install Opensolaris 2008.05 on SPARC. You can install Solaris eXpress Community Edition which has a SPARC version and is supposed to work with UltraSparc-II chips and newer. Right now SXCE is at Build 90. whilst opensolaris has not been updated from Build86 as yet.
Click on the Download Icon at the right hand corner here on the opensolaris.org site to download SXCE for SPARC. //Lars This message posted from opensolaris.org
