DHCP failure with Intel I219-V

[mgperkow]

Yes, the 840 G3 does default to UEFI, but I am doing a BIOS / Legacy boot. Unfortunately, what I'm doing requires a BIOS boot.

I'm reasonably certain this is some sort of driver glitch. Looking through the intel.c source code in iPXE and reading past posts (both on this forum and elsewhere on the Internet), it seems like the I219 series adapters have had a history of presenting problems time and again. Indeed, I've successfully used this same iPXE binary with about half a dozen other network adapters where I work. The I219 is the first one that has given me such significant problems.
