Thank you for replying.
I followed instructions on this site for the initial install:
http://blog.codefront.net/2007/06/26...newbies-guide/
So to install it I ran " apt-get install ubuntu-xen-server "
The install seemed to complete ok but then I rebooted and my D600 was stuck in a never ending loop. The last line would complain about PAE not on a PAE capable CPU (the same error as originally posted here).
I then followed instructions found here:
http://www.howtoforge.com/ubuntu_7.0...m_repositories
I retraced my steps went back through the install again and configured the config files as recommended. My D600 still loops on boot and the only past is to hit ESC and select a different kernel boot. Doing this messed up a number of things on my desktop like my screenlets for some reason all initialize on bootup into the GUI and I have to restart compiz everytime. THings have not been the same since the attempt to play around with XEN.
At this point I just want to remove so I can get everything else working properly again.
To your other request here is my menu.lst output.

## default num
# Set the default entry to the entry number NUM. Numbering starts from 0, and
# the entry number 0 is the default if the command is not used.
#
# You can specify 'saved' instead of a number. In this case, the default entry
# is the entry saved with the command 'savedefault'.
# WARNING: If you are using dmraid do not change this entry to 'saved' or your
# array will desync and will not let you boot your system.
default 0
## timeout sec
# Set a timeout, in SEC seconds, before automatically booting the default entry
# (normally the first entry defined).
timeout 3
## hiddenmenu
# Hides the menu by default (press ESC to see the menu)
