ipxe on intel i210-at

[robinsmidsrod]

Did you try to just build ipxe.usb and boot that to verify the hardware works? If that works then you should build bin/VVVVDDD.rom and flash that. If your NIC is onboard then you need to flash the motherboard, with a modified firmware for the motherboard. That is not recommended, and can easily cause your motherboard to be bricked. Unless you're experienced with these things I would recommend you PXE boot from a tiny usb stick with ipxe.usb instead of flashing the motherboard.
