I now have OpenBSD installed on my Sun Blade.

A quick search of Google revealed how to get access to the OpenBoot prompt, and then it was easy to install OpenBSD. I ran into an issue getting X up, but again Google came to my rescue. Now, it's running pretty smoothly.

I named my Blade sparky. (A SPARC-based system named sparky -- how unoriginal, I know...)

Update: I later decided to rename the host to razor. Sun Blade; razor blade... Yea...
