 The file undionly.kpxe is located in the /tftproot/ folder. The file undionly.kpxe is located in the /tftproot/ folder.
 +To build undionly.kpxe run:
 +    wget http://​kernel.org/​pub/​software/​utils/​boot/​gpxe/​gpxe-1.0.1.tar.bz2
 +    tar jxf gpxe-1.0.1.tar.bz2

 +    make DEBUG=http,​iscsi,​tftp,​dhcp bin/​undionly.kpxe&&​sudo cp bin/​undionly.kpxe /​tftproot/​undionly.kpxe
 +==== Using pxelinux, menu.c32 and dnsmasq to chainload gPXE ====
 +If you want to test gPXE but you are using extensively pxelinux and you do not want to break the rest of your configuration,​ you can add a menu entry to load gPXE.
 +The ''/​etc/​dnsmasq.conf''​ should contain something like:
 +    #DHCP
 +    domain=mydomain
 +    dhcp-range=,​,​,​30m
 +    dhcp-option=option:​router,​
 +    dhcp-authoritative
 +    ​
 +    # TFTP part
 +    enable-tftp
 +    tftp-root=/​tftproot
 +    # PXE
 +    dhcp-boot=/​tftproot/​pxelinux.0
 +    # required by old versions of gPXE (e.g. the one that comes with OracleVM)
 +    dhcp-no-override
 +The ''/​tftproot/​pxelinux.cfg/​default''​ should contain:
 +    DEFAULT menu.c32
 +    PROMPT 1
 +    ​
 +    LABEL gpxe
 +    MENU LABEL gPXE - chainload gPXE from a PXE capable NIC
 +    KERNEL undionly.0
 +On an Ubuntu system install ''​syslinux''​ package and make ''/​tftproot/​pxelinux.0''​ symlink to ''/​usr/​lib/​syslinux/​pxelinux.0''​.
 +The file ''/​tftproot/​undionly.0''​ is a symlink to ''/​tftproot/​undionly.kpxe''​.
