[SPARCbook] Sparcbook S1 OSes

[Wm. Josiah Erikson]

Hello all,
	I'm having little luck trying to figure out a decent OS I can run 
on my S1. It currently has SunOS 4.0 installed on it, and I have no 
passwords. I could root it, I suppose, but I don't really know how or 
where to go to find out :)
	I would really like to install OpenBSD, NetBSD, or linux on it. 
Does anybody know if this is possible? I've tried booting it from the 
SPARC boot disks for NetBSD and OpenBSD, and no luck - it doesn't even 
find the file to boot from for some reason. There doesn't appear to be a 
STOP key to get to the "normal" OpenBoot that I'm used to.
