UEFI Support

Introduction

Some devices have firmware bugs which mean they do not include a valid ESRT table in old firmware versions.

Create a 'fake' UEFI device with the lowest possible version so that it can be updated to a version of firmware which does have an ESRT table.

GUID Generation

All the HwId GUIDs are used for the fake UEFI device, and so should be used in the firmware metadata for releases that should recover the system.

Vendor ID Security

The vendor ID is set from the BIOS vendor, for example DMI:LENOVO

External interface access

This plugin requires no extra access.
