Hi everyone

Long time ago we received this e-mail at our edk2 mail list (later moved
from sourceforge).
The question was about adding accessibility at pre-OS environment.

Since I was looking for some new challenge I accepted this as one, and
started my mastering degree studies with focus on creating the foundations
of accessibility at pre-OS, by creating a simple HdaLib.

As soon as I conclude my Msc, on wednesday, I'll translate my thesis to
English and ad it to my github account (currently it's in Portuguese if
someone would like to have access before the translation).

The result of this work can be found here:
https://github.com/RafaelRMachado/Msc_UefiHda_PreOs_Accessibility
And here: https://www.youtube.com/channel/UCStjmPCMfi4Vqw-v3j8s8Fg

The initial steps for accessibility at pre-OS are there for the community.
There is a lot of work to be done yet, but doing it together we can make it
work.

Hope you like it.
Any question please let me know.

Thanks and Regards
Rafael R. Machado
