No IP Adress - likely missing ethernet driver

Actually, I may just have solved my own problem... it looks like the I210 and I211 series NICs use the same driver, and you have this in the custom nvme kernel (which coincidentally, I also need as I am using one of these - the install previously erased my music storage drive which is an m.2 SSD - doh!)

Yup. The same driver will work.

As for it erasing your music storage drive. That will only happen if you're install your OS on that same SSD? If you go through the installation, there should be a screen that says existing data will be wiped. The reason why I go with this complicated installation process and not a one click install is to prevent exactly this.

Hope you have a backup of your music?

If you want to keep your data on the existing SSD safe, use the advanced partition manager, a writeup is included here.
