Add iPXE support for Connectx-3-Pro MT27520


I use connect-3-pro cards on hp machines to boot via ipxe but getting attached errors. Apparently, the iPXE does not support connect-3-pro cards. just wondering is there any chance to add ipxe support for the cards.



Hi Bal,

Based on the ‘flint’ output you are using a Mellanox HP OEM card (HP Ethernet 10Gb 2-port 546FLR-SFP+ Adapter (779799-B21). Based on this information, you should contact HP for support as HP is capable of changing the capabilities for this adapter.

Thanks and regards,

Hi Bal,

Thank you for posting your question on the Mellanox Community.

Based on the information provided, you maybe running an outdated version of Flexboot/UEFI on your ConnectX-3 Pro.

Please open a Mellanox Support so you can request the latest available version applicable for your ConnectX-3 Pro.

Thanks and regards,
