The second try with a working Core WAN NIC went slightly better. Wound up at a Failed to Start X error. No problem, dove into the wiki here:
http://wiki.linuxmce.org/index.php/ZOTAC_ION. Down at the bottom is says to set your xorg.conf to 'vesa' from 'nv'. Much easier said than done.
Logging into the MD left me at a prompt as the sambahelper user. That's where I am stuck. Every time I try doing anything it says I don't have permissions and every time I try logging in as root...I don't know the password and the one I have on the core doesn't seem to work. I even managed to get into vim and fumble around enough to change 'nv' to 'vesa' but I couldn't save. Permissions forbade me. Some prodding or help is politely asked for from the community.
PS...according to the wiki the default password for sambahelper is nothing or just hit enter. Says I have the wrong password when I try that.
I had a similar issue on my Zotac 330 Ion. I couldn't use sudo on the MD because sambahelper told me I had the wrong password. To get around this I had to set an actual root password for the MD.
When you log into the MD your prompt should tell you what moon# the MD is... remember the number.
On the core/hybrid you need to open a terminal in KDE or press Ctrl-Alt-F1 to get tty1. Login with your username and password. Then to become superuser type:
$ sudo su -
and enter your password. Change directory to /usr/pluto/diskless and chroot into the MDs structure. Once you have done this you can change the root password for the MD with the passwd command.
# cd /usr/pluto/diskless
# chroot XX <-- replace XX with the moon number (device number) of your MD.
# passwd
Enter new UNIX password:
Enter the root password for the MD and then exit the chroot environment and give up superuser by typing 'exit' twice.
# exit
# exit
$
Now you can login as root on the MD with the password that you just set and you will be able to edit your xorg.conf file.
