In the research that I had done about this, I had found the following material.


The FreeBSD Foundation is pleased to announce that Benno Rice has been
awarded a grant to implement the ability to boot FreeBSD in the
Unified Extensible Firmware Interface (UEFI) boot environment.

The work to be done includes a new version of the loader, kernel
modifications to support starting from a UEFI environment and the
ability to create install media for pure UEFI systems.

“UEFI support is critical for FreeBSD’s future on the amd64 platform
and I’m really pleased to be able to ensure that FreeBSD gains support
for it,” said Benno.

This project is expected to be completed in March 2013.

I think an error may exist, regarding the post publishing date, and
its relationship to the expected date of completion of the project.

But, because of what I understand to be the relationship between
FreeBSD and PC-BSD, I assume that a development such as the one
mentioned in that article, would impact on PC-BSD.

Please advise regarding that, and, whether anything is known of any
progress in the project "to implement the ability to boot FreeBSD in
the Unified Extensible Firmware Interface (UEFI) boot environment".

Thank you in anticipation.
