Just wanted to post my experience with the Zotac ION board as an MD.
I'm running a Zotac IONITX-C-U with the brick 90W PSU and 1Gb of memory.
As a case i used the M350, which can be mounted on the wall or on the vesa mounts of the monitor. Nice little case.
My Core is an old A7N8X deluxe board on which i added a gigabit nic. I installed the June 1, 2010 snapshot on the core as a fresh start. This also went very smooth.
PXE boot as advertised, just set the BIOS options where they need to be, look in the ZOTAC ION Wiki.
After boot in my case i got a black screen and had to press 3 (and wait) to get the AVwizard to show, after this i selected hdmi2 with 1080p on 1 MD and hdmi2 with 720p on the second.
MD 1 is connected to a 47" Philips LCD (1080p max resolution)
MD 2 is connected to a 65" Hitachi DLP (1080i max resolution) connected to a Onkyo TX-SR606 Receiver
For the sound i selected hdmi and went to tty2 (CTRL-ALT-F2) and made sure that all alsamixer channels were unmuted and the volume up. I instantly had sound through hdmi, i even got the 2 "advanced" sound options.
After it all installed and the orbiter was generated i had to reboot the md to make the onscreen orbiter show up.
Now everything worked as you expect, except a few items i had to install.
1st the Medibuntu key is not installed, so doing an apt-get update will complain, just run
wget http://packages.medibuntu.org/medibuntu-key.gpg && sudo apt-key add medibuntu-key.gpg && rm medibuntu-key.gpg
2nd the libdvdcss2 package is not installed and (some) ripped dvd's will not play, just run
apt-get install libdvdcss2
mp3's played fine, but other codecs might be needed.
Overall i had a "works OOTB" experience and it's great to see it work like that.
Thanks to all who worked on this,
