LAN Boot Select
The LAN boot, i.e., Preboot eXecution Environment (PXE)
allows you to boot computers using a network interface
independently of data storage devices (like hard disks)
or installed operating systems. Enable or disable this
function on the management port (LAN1 to LAN8 on the
front panel) with this option here.
