I would like to install Debian 8.9 (Jessie) on a HP EliteBook 840 G4 laptop.
lspci (when executed from a shell launched from inside Debian Installer) informs me that it possesses the following Ethernet device:
Ethernet Controller: Intel Corporation Device 9d21 (rev 21)
The laptop is plugged into Ethernet, and a WLAN network would be available as well.
Early on during Debian installation (at step "Detect network hardware") I run into the following problem: The installer informs me that no Ethernet card was detected and that a driver is needed for my Ethernet card. It then presents me with a long list of choices, but among them is no obvious match to
Intel Corporation Device 9d21 (rev 21).
I've tried the installation process by booting both from the
firmware-8.9.0-amd64-netinst.iso netinst images, but ran into the same problem each time.
So what is needed in order to install Debian 8.9 on that particular laptop?
