Hello,
I have a installation of zeroshell on a notebook with a Intel Dual Band Wireless AC 7260 chip.
This WiFi chip need the firmware file ‘iwlwifi-7260-17.ucode’ which is not included in /etc/firmware.
I copied /etc/firmware/* to /Database/etc/firmware/ and added the iwlwifi-7260-17.ucode file.
This Pre-Boot-Script:
# Pre Boot Startup Script
#
# Firmware update for iwlwifi
#
modprobe -r iwlmvm
rm -Rf /etc/firmware
ln -s -f /Database/etc/firmware /etc/firmware
modprobe iwlmvm
makes the new Intel WiFi chip work.
This way of adding firmware files should work for other firmware files too.
