The PC running Solaris has on the first hard disk OpenSolaris and on the second (through chainload) OpenSolaris. At home I gave a third computer with three drives: Solaris 10, SXDE and OpenSolaris. I have never tried a single disk dual boot for multiple Solaris OS.
The laptop I mentioned has XP and BSD on one and the same disk. This message posted from opensolaris.org
