if you do reinstall, you will need to install from /sys/src/boot/pc-e820
not /sys/src/boot/pc. if you leave /sys/src/boot/pc there or not doesn't matter.

i don't believe you've installed the version of 8169 in
my contrib.

that didn't come out right.  if you're using the new sd stuff, then
these command will work, and you might find them useful.
smart has a better chance of being useful than the rather esoteric
atazz.

this was just fyi.  these will be differences between the prebuilt
kernel on the iso and one you can rebuild yourself.

i forgot some things like jumbo frames, too.  this is important
for good aoe performance.  i've gotten over 1GB/s of sustaned aoe
traffic on a lowly 1.6ghz xeon 5000 machine over a myricom
10gbe card.  when i get back to working on the myricom stuff,
i will post a link to the exact setup.

again, the iso is just kind of a bandaid.  the contrib packages
are, too.  it's all quite unsatisfactory.  sorry i havn't done a better job.
i'm up for suggestions.
