I have an Acer C100F3 server with i3-4150T CPU and two I210 NIC and one I217 NIC. When I use jun's loader 1.02b, it is not visible on the network after booting. I have tried the loader with or without your driver package, and it's the same result. (When I try XPEnoboot 5.2, it can be detected on the network)
And I tried loader 1.03a2, it's not visible on the network either.
And I noticed that when I boot the server with jun's loader 1.02b, the led of nic is not lighted, so I think the nic is not working. But when I edit the grub.cfg file, from
initrd $img/rd.gz $img/$extra_initrd
to
initrd $img/$extra_initrd $img/rd.gz
and boot the server with the edited loader, the led of nic is lighted, but the server is still not visible on the network.
