At 10.0 no UEFI in site, network worked fine once I convinced it it was a
hostname and hosts based lookup, although i do seem to recall blowing
away dchpdc5 or something, what ever it was that insisted my route came
from agahi. Once that was done it did everything I asked it to do for
about a month, with zero hiccups until I had to get my heart rebuilt (
new aortic valve and a bunch of stents, and the lathe running as I had to
make something that was bigger than my 7x12 could handle well.
