I just acquired a SunPCi 400mHz inboard for my U5/400. I've got to say that I'm impressed at how well it works. For my few uses for Windows (Visio, like everybody else), it does the job very well. At $19+shipping, it was a great bargain. Has anyone tried running Solaris/x86 on one of these? I noticed that the drivers are present, but undocumented.
