I would like the HID keyboard to support working in BIOS. The current built in HID keyboard does not support working in BIOS. There is this library that works for me on arduino. Specifically BootKeyboard. https://github.com/NicoHood/HID/blob/master/src/SingleReport/BootKeyboard.cpp
Is it possible to either use this library or to modify the device os to have the keyboard act like this? I think the technical ability I want is called HID_BOOT_PROTOCOL or USB HIDBP
I tried applying this patch: HID Keyboard Packets
but it is a bit outdated and doesn’t work on modern firmware and I’m not sure if that does it.
