Solaris 10 init 0 and boot disk1 on same command line

Hello all,

       Fairly simple question here.  I know that in Solaris 10 there is a way to tell a system running solaris 10 to init 0 and then boot disk1 all in the same command line from a SSH window.  That way once you hit enter it then performs the init 0 and then does the boot disk1.  You have to seperate the commands with a special character or something but I don't remember how.  Anybody help me out with this?  Thanks in advance.

i know that:

reboot -- -s

reboots in single usermode! and this is the same as "boot -s"
try this one, should work:

reboot -- disk1

something like this:

?
