Hmm. I always hate it when that happens. I have some friends who are
working with some chipsets supposed to be involved with the
spec. Their group seems to have decided to abandon all non-MS work
though, so my interest has somewhat lapsed.

I'd heard that PCI officially specs some variation of the Sun
sbus forth as official byte code for device BIOSes. I do not know how
this and I20 interacts.
Back to serial device stuff: I would welcome pointers to work done
to rethink the serial device stuff. I read the plan9 papers a long
time ago, I'm going to reread some of that stuff, and the v8 streams
stuff if I can find it.
