================================================================================
  QuantaMesh COME CPU board (Broadwell-DE)
================================================================================

  QuantaMesh switch which supports modularized CPU board design, have a
non-programmable H/W component for mother board detection. For motherboard
detection, please refer to ``busybox/miscutils/mb_detect.c``

  Supported Platforms
=======================
 - T7040-IXAE (cpu module)
   40x100G QSFP28 ports

 - T7080-IXA (cpu module)
   80x100G QSFP28 ports

 - For more detail product information, please refer to
   https://qct.io/

  Specification
=================
 - Modularized CPU board design
 - 1 RJ-45 out-of-band management port (10/100/1000M)
 - 1 RJ-45 console port
 - 1 2x16GB DDR4 SDRAM
 - 1 M.2 NVMe SSD 128GB, maximum to 2x256GB
 - 1 USB 2.0 port

+Installing ONIE on Quanta COME CPU board
+============================================================
+
+Cross-Compiling ONIE
+====================
+
+To compile ONIE first change directories to ``build-config`` and then
+type ``"make MACHINEROOT=../machine/quanta/ MACHINE=quanta_come all"``.  For example::
+
+  $ cd build-config
+  $ make -j4 MACHINEROOT=../machine/quanta/ MACHINE=quanta_come all
+
+Or, change directories to ``machine/quanta/quanta_come`` to compile ONIE,
+use ``build.sh`` to compile ONIE. For example:
+
+  $ cd machine/quanta/quanta_bwde
+  $ ./build.sh all
+
+When complete, the ONIE binaries are located in
+``build/images``::
