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`
