Oh, and another unrelated question:
Would I better off using OpenSolaris or Solaris Community Edition?
I suspect SCE has more drivers (though mayby in a more beta state?), but its
huge download size (several days in backward New Zealand, thanks Telecom NZ!)

I'm going the other route here, and using a Intel small server

I'm currently trying the Supermicro X7SBE, which supports a non-Xeon
CPU, and _should_ actually use the (unbuffered) ECC RAM I have in it.
It can also support a network KVM IPMI board, which is nice (though not

Which mode woud you use? Max seems the most appealing, why would anyone use

I am glad this
More choice is good!
It seems Intel's server boards sometimes accept desktop CPUS, but don't support
speedstep. Is all OK with those?

Note that the 'ecccheck.pl' script depends on the 'pcitweak' utility
which is no longer present in OpenSolaris 2009.06 and Ubuntu 8.10
because of Xorg changes.
This is exactly the kind of hidden trap I fear. One does everything right and
then discovers that xx is missing or has been changed
i7 doesn't support ECC even motherboard supports it, you need XEON W3500 which
costs the same as i7 to support ECC.

Good news; the manual for the M4N78-VM mentions ECC and gives the following
BIOS options: disabled/basic/good/super/maxi/user.
Unsure what these mean but that's a start.
