[installnic concerns xNBA, doesn't it] ?
the behavior is determined by the "boot order" in bios settings, if the selected network boot device("installnic" you mentioned) is not available, the next boot device specified in "boot order" will be tried, this is the behavior of bios, not xNBA.
"xNBA" is a patched version of ipxe/gpxe, which complies with the PXE specification,

For instance you set up BIOS to PXE on (what the OS will call) eth2 but
installnic in noderes is set to eth1.
For instance you set up BIOS to PXE on (what the OS will call) eth2 but
installnic in noderes is set to eth1.
The network boot device specified in BIOS, eth2 in your example, will send out dhcp discover packet, however, since nodders.installnic is set to eth1, hence the management server(DHCP server) side only presents dhcp lease for "eth1", "eth2" cannot obtain lease from management server(if no dhcp range configured),the network boot will fail, and the next boot device specified in bios "boot order" will attempt.
If you did not specified any specific NIC as the network boot device, all active NICs will send out DHCP discover, it is another story.

Or, to state it differently : if for some reason installnic is not
available, does xNBA fallsback to whatever works (in BIOS order) ?
[installnic concerns xNBA, doesn't it] ?
Thanks.
