Backup the cards current board definition file just in case

flint -d /dev/mst/mt4099_pci_cr0 dc orig_firmware.ini

Flash the FCBT image to the card

flint -d /dev/mst/mt4099_pci_cr0 -i fw-ConnectX3-rel-2_42_5000-MCX354A-FCB_A2-A5-FlexBoot-3.4.752.bin -allow_psid_change burn

Reboot

start mst service again

mst start

Get detailed firmware info

mlxfwmanager --query

Get the device ID again:

mst status

Use it to see the cards current configuration:

mlxconfig -d /dev/mst/mt4099_pci_cr0 query

Switch ports from VPI/Auto to Ethernet only:

mlxconfig -d /dev/mst/mt4099_pci_cr0 set LINK_TYPE_P1=2 LINK_TYPE_P2=2

Turn off bootrom crap

mlxconfig -d /dev/mst/mt4099_pci_cr0 set BOOT_OPTION_ROM_EN_P1=false
mlxconfig -d /dev/mst/mt4099_pci_cr0 set BOOT_OPTION_ROM_EN_P2=false
mlxconfig -d /dev/mst/mt4099_pci_cr0 set LEGACY_BOOT_PROTOCOL_P1=0
mlxconfig -d /dev/mst/mt4099_pci_cr0 set LEGACY_BOOT_PROTOCOL_P2=0

Optional: delete bootrom off the card, so it doesn't slow down boot by popping up crap (safe & supported)

flint -d /dev/mst/mt4099_pci_cr0 --allow_rom_change drom
