Chainload iPXE using dnsmasq

This information pertains to FOG 0.33 and the new iPXE boot method.

In order to continue to use dnsmasq to dole out ip addresses and to help find the boot file, some changes need to be made to force the boot file to load the iPXE boot file.

The old pxelinux.0 file is still included in the fog installation. We need to rename it to meet the naming scheme set forth by dnsmasq, but the file still exists.

Open a command line and navigate to the tftpboot folder:

cd /tftpboot
sudo mv /pxelinux.0.old pxelinux.0

Now create a default file for pxelinux.0 to load (you may substitute gedit for your favorite text editor):

sudo mkdir pxelinux.cfg
cd pxelinux.cfg
sudo gedit default

Now insert the following lines and edit the server ip address to reflect your own fog server:

DEFAULT vesamenu.c32
LABEL fog
    MENU DEFAULT
    kernel ipxe.krn dhcp && chain http://(fog-server-ip-address)/fog/service/ipxe/boot.php?mac=${net0/mac}
PROMPT 0
