-====== OS Install: PXE Boot ======
-**General Information**
-In order to install an OS via PXE boot, a TFTP and DHCP server are required.\\
-Using PXE allows for clients to begin a network installation without any net-install ISO.
-**Checklist**
-  * Distro: Enterprise Linux 7
-  * Installation Server Created (NFS/HTTP/FTP) that is hosting the install DVD and kickstart file
-----
-====== TFTP Server ======
-  * Install the required packages<code bash>yum install tftp-server xinetd</code>
-  * Allow TFTP access (set disable = no)<code bash>vim /etc/xinetd.d/tftp
-service tftp
-{
-  ....some other variables...
-  disable = no
-  ....some other variables...
-}</code>
-  * Start and Enable xinetd<code bash>systemctl start xinetd
-systemctl enable xinetd</code>
-  * Allow through firewall (if enabled)<code bash>firewall-cmd --permanent --add-service=tftp
-firewall-cmd --reload</code>
-----
-====== DHCP Server ======
-  * Install required package<code bash>yum install dhcp</code>
-  * Edit DHCP config and customize per your network<code bash>vim /etc/dhcp/dhcpd.conf
-subnet 192.168.1.0 netmask 255.255.255.0 {
-  option routers 192.168.1.254 ;
-  range 192.168.1.240 192.168.1.250 ;
-  next-server 192.168.1.150 ;
-  filename "pxelinux/pxelinux.0" ;
-}
-</code>
-    * subnet => specify the network
-    * netmask => mask for your network
-    * option routers => gateway for the network
-    * range => start and ending IP to hand out via DHCP
-    * next-server => IP of the TFTP server
-    * filename => file that should be offered to systems doing PXE boot (relative to the TFTP server's root)
