Hello Erik,
the problem is not in transmission speed of network.
mine is based on 9front.
messages that come from booting process is as follows:
(1) the content in plan9.ini.
(2) then single letter hexadecimal messages 0 1 ... a b .. f 0 1 ...
(3) and then "boot". the message comes from bootfat.
(4) finally "Plan9" message from the loaded kernel.
the message (2) is very slow and takes much time to finish.
I suspect bootfat takes too much time to find a specified kernel in fat partition.
the time is mother board dependent.
my new one is sufficiently fast, but old one (GA-G31M-S2L) is irritatingly slow.
Kenji Arisawa
P.S.
I accessed http://ftp.9atom.org/other/9paecpu to try your 9atom.
however I got "Object not found".
