Configuration
Disable Secure Boot
To disable Secure Boot, the following steps must be performed:
- Enable UEFI-only loading (no legacy support)
- Set an administrator password
- Disable secure boot
LTE modem
The modem is FCC locked.
Queltec
A script to enable the radio is installed by net-misc/modemmanager, but a link to it must be manually created:
root #
mkdir -p /etc/ModemManager/fcc-unlock.d
root #
ln -s ../../../usr/share/ModemManager/fcc-unlock.available.d/2c7c:030a /etc/ModemManager/fcc-unlock.d/
