i think if your network card has "UEFI secure boot" you have done something wrong. probably a lot of things

i counted at least 6 different pieces of firmware when looking at it component by component (if you can call a 128 GB eMMC with Ubuntu on it "firmware")

i thought this network card runs linux

i was wrong. it runs TWO copies of linux

@whitequark Is it like cisco's UCS systems where the firmware comes in pairs? one live an the other cold where you update the cold one and reboot into it, leaving a working backup. Or did they do something monstrous like having separate instances for each 200Gb interface, with some sort of sync/interconnect API?

@whitequark Both the controller and the BMC are running Linux!?!? No wonder the firmware update is cursed.
