Booting in ONIE Update Mode

© Copyright Lenovo 2017
ONIE update mode installs a new version of ONIE on the switch, including the
Linux kernel. It works similarly to the ONIE install mode, except the discovery
process searches for an ONIE image instead, and not a NOS image.
Notes:
 This only upgrades the ONIE partition on the switch and does not affect the
NOS image.
The ONIE updater image is called
onie-updater-x86_64-lenovo_ne2572-r0.
 After updating ONIE, the boot priority must be changed from the BIOS menu to
enable the switch to run Cloud NOS:
You can interrupt the startup process of the switch and enter the BIOS menu

from the serial console port. When the system displays the following
message, press Delete or Esc.
Press <DEL> (Terminal Not applicable) or <ESC> to enter setup...
The BIOS menu appears.
