As others have pointed out, shutdown -p is what you want. In NetBSD on Sun hardware with OpenBoot firmware "shutdown -h now" gets you back to the firmware prompt. The OS halts and you're dropped in "BIOS", so to speak. It works over serial too, so you can use it headless. I believe Solaris works this way too, but I haven't tried it myself. I really like the Sun Blade 100, but I'm extra sensitive to noise, so it's got to go. :I /Jonas Sundström. www.kirilla.com
