Recently i tried to install latest Solaris SPARC build using DVD written by nero on my laptop.. Bingo !!! no use – boot cdrom command always showed
Can’t read disk label. Can’t open disk label package . Did all kind of troubleshooting and wasted 4 DVDS. Later i used alcohol 120% – thats it worked. www.alcohol-soft.com/
So burn your Sparc ISO image on your x86 laptop/system using alcohol 120% burning software. It will work.
