Hello
I’ve a 6 month old HeroBox with Intel Network Adapter on Board (I think it is Intel 225V on Board).
I’ve installed a KVM (Proxmox) in the HeroBox and it runs for about 6 month perfectly. Now after reboot the Proxmox-OS cant detect the network adapter anymore. At the boot screen i can see that the linux driver for the network adapter (igc) shows the message “NVM checksum is invalid”. Googling the web tells me to flash the NVM from the network adapter.
Can you support me with any tools to flash the network adapter. Would be great to use the herobox longer then 6 month 
BR
Eric
