On a lark, I just tried booting the 1.5.2 miniroot on an Ultra-30.

I didn't expect much, since the Ultra-30 isn't on the supported
hardware list anyhow, but here's the result of the boot, below.

Is Ultra-30 support expected in a future release, say, 1.5.3?

What is the lineage of the Ultra-30 motherboard?  What's its
closest relative?  Ultra-60?  E250?  Netra-T1?


Regards,
Mike
