Oracle won't start

I have a Sun box with Solaris 2.8 and Oracle 8.1.6. I have set my semaphores according to the directions as far as I can tell. My current database is a fresh test box install and has no users and nothing on it. I log in to svrmgrl and shutdown immediate. Sits there for about 2 minutes and then shuts down. Not sure why it's not quicker than that, especially with my current setup.

Anyway, when I do a startup, I sometimes get an error message, and excuse me for not listing it here, but it's not showing up right now, that basically people would respond, you do not have your semaphores set correctly. Can someone please check my settings listed below from the system file and let me know if I'm figuring things wrong? Thanks.
