@george1421 Hi, thank you for your advise. I will contact the vendor to access the list of approved NICs.

We are running the dhcp within the fog server. It is a CentOS 7 system. I will modify the dhcp settings to use snponly.efi to try boot from the add-in card as soon as we source a compatible one.

Thanks again for your help.

@hybride Hi, I am on the same boat regarding the built-in NIC on the Lenovo P620. I would like to explore the option you suggested with the add-in PCIe NIC card.

Pressing F12 to bring up the boot menu I cannot see listed the add-in 1GBe card. Did you have to take extra steps on the UEFI bios to make it show up on the boot menu?

Please would you mind sharing with me the model of 1GBe card that worked for you.

When you mentioned to put snponly.efi on option 67. Please could you give me extra details on where to put this file and how to perform this change.

Thank you in advance for your help.
