How to crossflash intel X710 OEM cards

Disclaimer

ONLY do this if you understand what this script does and when you are sure that this method is applicable to your card!!!

I'm not responsible for your doings! You are flashing the firmware of your ethernet card, in the worst case you endup with a soft- or even hardbricked card! Also this might void your warrenty.

Having said this, if you are uncertain if this will work for your card be sure to dump the ROM with a RPI, RPI Pico or 3.3v moded SPI-Flash Programmer:

sudo flashrom --programmer ch341a_spi -c "W25Q64BV/W25Q64CV/W25Q64FV" -r lenovo_X710-DA2_FW9.3.bin

Repeate this at least 3 times and check that all three dumps have the same checksum, use e.g. sha256sum

Why crossflash

Many OEM (lenovo/dell/hp) ethernet x710 cards have some features disabled, in my case my LENOVO INTEL X710-DA 00YK615 doesn't support SR-IOV.

This guide tells you how to flash the original intel firmware and boot image on your card to enable all features.

Flash

You need to run all of this as root:

$ sudo -i

Download the latest intel-ethernet-adapter-complete-driver-pack, e.g. version 29.0, update the link if a newer versions exist:

$ WORKDIR=/opt/intel_x710_ethernet_fw && \
  mkdir -p $WORKDIR/download_pkg && \
  cd $WORKDIR/download_pkg && \
  wget https://downloadmirror.intel.com/816410/Release_29.0.zip

Unzip and prepare files:

$ unzip Release_*.zip && \
  rm Release_*.zip && \
  cd NVMUpdatePackage/700_Series && \
  tar -xf 700Series_NVMUpdatePackage_v*_Linux.tar.gz && \
  cd $WORKDIR && \
  VERSION=$(cat download_pkg/NVMUpdatePackage/700_Series/700Series/Linux_x64/version.txt) && \ 
  mv download_pkg/NVMUpdatePackage/700_Series/700Series/Linux_x64 $VERSION && \
  mv download_pkg/APPS/BootUtil/Linux_x64/DRIVER $VERSION/ && \
  mv download_pkg/APPS/BootUtil/Linux_x64/bootutil64e $VERSION/ && \
  rm -rf download_pkg && \
  chmod +x $VERSION/nvmupdate64e && \
  chmod +x $VERSION/bootutil64e && \
  chmod +x $VERSION/DRIVER/install

You may need to install the kernel headers if they are not present on your system:

  • debian: apt install linux-headers-amd64
  • proxmox: apt install pve-headers
  • ubuntu: apt install linux-generic
  • rocky: dnf install kernel-headers-$(uname -r)

Install the QV driver, it is needed to flash the card.

$ cd $WORKDIR/$VERSION/DRIVER && ./install
Extracting archive...OK!
Compiling the driver...OK!
Directory for driver installation does not exist...need to create it.
Directory for driver installation created successfully.
Skipping removing QV driver - it does not exist...
Copying iqvlinux.ko driver file to /lib/modules directory...OK!
Driver installation verification...Installed!

Check which is the right card:

$ cd $WORKDIR/$VERSION && ./bootutil64e

Run ethtool on your nic to get the ETrackID, here it is 8000ee1c:

$ ethtool -i enp1s0f0
driver: i40e

supports-test: yes
supports-eeprom-access: yes
supports-register-dump: yes
supports-priv-flags: yes

Backup the default config file:

$ mv nvmupdate.cfg nvmupdate.cfg.bak

and create your own, put your ETrackID into the REPLACES block.

$ cat <<EOF > nvmupdate.cfg

Now update the Firmware, the -rd flag resets the vendor settings:

$ ./nvmupdate64e -rd

I do have a Dell X710-DA2 with latest firmware and etrackid 0x8000e9c2.

Flash X710DA2_9p56_CFGID7p2_J51959_Retail_8M.bin or X710DA2_9p56_CFGID7p2_OEMGEN.bin ?

I had to upgrade 4 X710-DA2. 3 were 80003751, one was 800034E9. Based on NVM v6 and PBA, all these AI LLM pointed to an Intel card. Even though they had the dell part number sticker on them .
I used EFI mode. Put the bootutil, nvmupdate, nvmconfig, BootImg, the firmware file and UEFI shell on a FAT32 USB. On 3 of them I had to run the bootutil update.
This how they looked before upgrade

this was my config I used. After the first card, nvmupdate had some issue finding them. So I add the combinations of subdevice and EtrackId.
