UEFI Support
|
|
============
|
|
|
|
Introduction
|
|
------------
|
|
|
|
The Unified Extensible Firmware Interface (UEFI) is a specification that
|
|
defines the software interface between an OS and platform firmware.
|
|
With the UpdateCapsule boot service it can be used to update system firmware.
|
|
|
|
If you don't want or need this functionality you can use the
|
|
`-Dplugin_uefi=false` option.
|
|
|
|
UEFI Unlock Support
|
|
-------------------
|
|
|
|
On some Dell systems it is possible to turn on and off UEFI capsule
|
|
support from within the BIOS. This functionality can also be adjusted
|
|
from within the OS by fwupd. This requires compiling with libsmbios support.
|
|
|
|
When fwupd has been compiled with this support you will be able to enable UEFI
|
|
support on the device by using the `unlock` command.
|
|
|
|
Custom EFI System Partition
|
|
---------------------------
|
|
|
|
Since version 1.1.0 fwupd will autodetect the ESP when it is mounted on
|
|
`/boot/efi`, `/boot`, or `/efi`. A custom EFI system partition location can be
|
|
used by modifying *OverrideESPMountPoint* in `/etc/fwupd/uefi.conf`.
|
|
|
|
Setting an invalid directory will disable the fwupd plugin.
