# crossflash-x710-da2
# 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](https://wiki.flashrom.org/RaspberryPi), [RPI Pico](https://libreboot.org/docs/install/spi.html#raspberry-pi-pico) or [**3.3v moded** SPI-Flash Programmer](https://wej.k.vu/electronics/ch341a-mini-programmer-fix/):
```shell
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:
```shell
$ sudo -i
```
Download the latest [intel-ethernet-adapter-complete-driver-pack](https://www.intel.com/content/www/us/en/download/15084/intel-ethernet-adapter-complete-driver-pack.html), e.g. version 29.0, update the link if a newer versions exist:
```shell
$ WORKDIR=/root/x710-crossflash && \
mkdir -p $WORKDIR/download_pkg && \
cd $WORKDIR/download_pkg && \
wget https://downloadmirror.intel.com/843839/Release_29.5.zip
```
Unzip and prepare files:
```shell
$ 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 | tr -d '\r') && \
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.
```shell
$ 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:
```shell
$ cd $WORKDIR/$VERSION && ./bootutil64e

Look which nic is the X710, here it is NIC 2 and 3. Now flash the cards boot image.
```shell

Run `ethtool` on your nic to get the ETrackID, here it is `8000ee1c`:
```shell
$ ethtool -i eth1
driver: i40e
version: 6.5.13-1-pve
firmware-version: 9.30 0x8000ee1c 1.2890.0

bus-info: 0000:01:00.0
supports-statistics: yes
supports-test: yes
supports-eeprom-access: yes
supports-register-dump: yes
supports-priv-flags: yes
```
Backup the default config file:
```shell
$ mv nvmupdate.cfg nvmupdate.cfg.bak
```
and create your own, put your `ETrackID` into the `REPLACES` block.
```shell
$ cat <<EOF > nvmupdate.cfg

```
Now update the Firmware, the `-rd` flag resets the vendor settings:
```shell
$ ./nvmupdate64e -rd

Now reboot
```shell
$ reboot

After reboot your card is now crossflashed!
```shell
$ ethtool -i eth1

All functions should be available, in my case SR-IOV:
```shell
