Yes, this is a very common problem and I've had basically the same
experience as you.  Finding tons of messages asking for help, no
replies with any definitive.  It would be great if someone who has
this working writes up an _explicit_ howto.  I know about a million
users would greatly appreciate it.  Btw, my ion system is a Zotac
IONITX-C-U..  Not that it matters, everyone is having the same
problem.
