Comment 2 for bug 1382259

For the vast majority of systems, we can't control the boot order of bare metal systems. Automated IPMI configuration is not a part of Fuel at this time, so this responsibility is on the local administrator to enable proper PXE boot behavior.

The documentation related to this is here: http://docs.mirantis.com/fuel/fuel-5.1/user-guide.html?highlight=boot#boot-the-node-servers
