Precision 7920 Rack - Mellanox ConnectX-5 missing from UEFI Boot
Hello,
I have a Precision 7920 Rack that I am trying to PXE boot from a PCIe Mellanox ConnectX-5 card. I put the Mellanox card into EUFI x86 mode (Ctrl-b), and then put the BIOS into EUFI mode, but it is not listed. If I put the BIOS back into legacy mode, they are listed.
Did I forget to enable something? I don't see what I am missing.

I've got the same problem. I did do some research, and found documentation stating that you need to use `mlxconfig` to enable two options: EXP_ROM_UEFI_x86_ENABLE and EXP_ROM_PXE_ENABLE. After doing so, I see the card listed in System Setup / Device Settings, but I still do not see it as a boot option for PXE-booting.
