=Setup Disk array=


The SAS hard drives are not recognized when the computer is first taken out of the box

You need to enter the '''Configuration Menu''' from the '''BIOS''' by hitting Ctrl-S.  You get to this point during the boot process by hitting any key after the computer has done a self diagnostic.

The Startup Splash screen takes a while to come up and looks like this

After the above is setup, the standard installation procedure from a Live DVD can be used to install CentOS 7

=Window manager=
== Install FVWM==

KDE was very slow so I installed FVWM using 

as root

 yum install fvwm

I then set the runlevel to 3 

 systemctl set-default multi-user.target


you then login as daq and create the file ".xinitrc" with the line entry

exec /usr/local/bin/fvwm


this will launch fvwm for you if you type the folowing on the command line

 ssh-agent startx


==Install Xfce==

did not use Xfce as a window manager but used fvwm above


 yum install epel-release

 yum --enablerep=epel -y groups install "Xfce"

then setup the graphical target


 systemctl isolate graphical.target


to keep it as the default

<pre>
sudo systemctl set-default graphical.target
rm '/etc/systemd/system/default.target'
ln -s '/usr/lib/systemd/system/graphical.target' '/etc/systemd/system/default.target

</pre>

the command below will check which GUI is used

 ls -l /etc/systemd/system/display-manager.service
