Fiano: Go Forth and Modify

In this talk we present Fiano, Go-based tools created at Google and Facebook for manipulating UEFI images. Fiano is fast, scriptable, easy to use, and most importantly, does not require you to have UEFI source -- you can modify UEFI ROMs, remove DXEs and, if desired, replace them with a Linux kernel.

Fiano puts you in control of your systems firmware. Even if your BIOS is a blob and outside your control, these tools will help you inspect your firmware (for example, malware analysis) and improve your security.

Fiano can also improve build times, making it possible for individual DXEs to be compiled and inserted into a prebuilt image, avoiding the need to rebuild the entire firmware image.

In the future, we hope to see more systems with a fully open-source firmware stack. Until such time, tools such as Fiano are necessary to give you freedom and act as a stepping stone to bring open-source into your firmware.
