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.

I was just trying to figure out why there was a specific listing for UEFI as a feature set on the ConnectX5 cards. Guess this answers my question.
