The BIOS settings for each server in the physical rack must match the values given below. It is a good practice to set the values in the order specified below to avoid any imaging failures.

If BIOS changes are needed to set the boot device, disable all NICs on each server except for the management port and dual port card. If the server can boot from the connected NIC cards, you do not need to disable the additional NICs.

For information on how to set the required BIOS values, refer to the vendor documentation.
