Access BIOS/UEFI menu setting via uefi shell

问题:

I´d like to read/alter some BIOS/UEFI menu settings via a uefi shell script.

For example I´d like to change the 'CSM Support' setting (Enabled/Disabled).

Is there any way to do so?

回答1:

Inspect the uefi variables (not shell variables) before and after you change the 'CSM Support' setting, maybe this setting is stored in one of the uefi variables, you can then edit this variable from the shell or a simple shell app.
