Hello helpful people,

I have just received 3x Lenovo 01GR250 CX4 2x25Gb cards. Is there an idiots guide out there to flash these to MCX4121A-ACAT firmware which is what they are under the skin :) ??

I searched the forums but couldn't see anything for Connectx 4 other than someone trying to hack a 50Gb to 100Gb.

Any help gratefully received!

Alex

I used the same procedure to flash a hpe card (825110-B21) to a vanilla mellanox nic (MCX455A-ECAT) as with the connect-x3 cards.

Thank you It did work with a bit of modifying, for any one wondering:
