True - but the experience is better with F2 (on "normal" computers/non-Chromebooks).

We've got a lot of feedback, and for most, people turn on their computers and start tapping Escape when they want Grub. If it's mapped, this gets intercepted by UiApp. Even if they exit, with BGRT in the equation, it requires fairly precise timing to access Grub.

Grub runs later. Then what does “conflict” mean?

We would prefer to keep PCD, as Esc can conflict with Grub on normal (not Chromebook) devices

 

Thank you

Can you just map both ESC and F2 to the UI? So that PCD is not needed.

Thanks,

Subject: [PATCH] UefiPayloadPkg: Make Boot Manager Key configurable

Provide a build option to use [Esc] instead of [F2] for devices
such as Chromebooks that don't have F-keys.
