+Installing ONIE on DELTA agcv208sv1 Switch (CPU Module : Intel Deverton CPU Module)
+================================================================================
+
+Cross-Compiling ONIE
+====================
+
+To compile ONIE first change directories to ``build-config`` and then
+type ``"make MACHINEROOT=../machine/delta MACHINE=delta_agcv208sv1 all"``.  For example::
+
+  $ cd build-config
+  $ make -j4 MACHINEROOT=../machine/delta MACHINE=delta_agcv208sv1 all
+
+When complete, the ONIE binaries are located in
+``build/images``::

+Cross-Compiling the DEMO OS
+===========================
+
+To compile the demo OS first change directories to ``build-config``
+and then type ``"make MACHINEROOT=../machine/delta MACHINE=delta_agcv208sv1 demo"``.  For example::
+
+  $ cd build-config
+  $ make -j4 MACHINEROOT=../machine/delta MACHINE=delta_agcv208sv1 demo
+
+When complete, the demo OS installer is located in ``build/images``::

+
+Installing ONIE on a Blank Machine
+==================================
+
+To install ONIE on a new machine use one of the onie-recovery images.
+
+Overview
+--------
+
+An "ONIE recovery image" is used for:
+
+1. installing ONIE on a blank machine, i.e. what manufacturing would
+   use.
+
+2. recovering a destroyed ONIE system.
+
+The recovery image is:
+
+. <machine>.iso       -- a hybrid ISO image.
+
+ISO Recovery Image
+------------------
+
+You can use the .iso image to create a bootable USB memory stick.
+Use ``dd`` to copy the .iso image to a USB stick and boot from that::
+
+  dd if=<machine>.iso of=/dev/sdX bs=10M
+
+Find the correct ``/dev/sdX`` by inspecing the ``dmesg``
+output after inserting the USB stick into your work station.
+
+To enable booting from USB in the BIOS:
+
+1. Insert the USB stick (needs to be in before configuring BIOS)
+
+2. Power on the S6010 and enter the BIOS configuration
+
+3. Set the USB device to "Hard Disk"::
+
+  Advanced-->USB Configuration-->Mass Storage Devices:
+      <Name of your device>    [Hard Disk]
+
+  <Name of your device> might be something like "SanDisk 1.26".
+
+4. Set the hard drive boot order::
+
+  Boot-->Hard Drive BBS Priorities-->Boot Option #1
+
+  In "Boot Option #1" select the device that corresponds to your
+  device.
+
+5. Save and Exit the BIOS configuration
