Re: [coreboot] coreboot on Thinkpad T420 : Ctrl and Fn key swap

Hi,
There is a CMOS option called "fn_ctrl_swap", you can set it with
nvramcui payload or with nvramtool.

coreboot on Thinkpad T420 : Ctrl and Fn key swap

[Angel Pons]

Hello Mathias,

The prebuilt images are older than two years. My advice would be to build
coreboot from source, from either master or 4.8.1 (4.8 is broken). To use
the fn/ctrl swap, enabling "Use CMOS for configuration values" in Kconfig
is needed.

Note that using nvramtool as Evgeny stated should be possible with the old
image though.
