Current UEFI based firmware stores its configuration data in the SPI flash next to the firmware code. Since you're supposed to copy your firmware image to somewhere safe to have a way to recover, that will also contain the latest configuration.

Hi,
Does flashing coreboot/tianocore payload change the settings options
available in the BIOS setup of a device? I'm talking about the
device/hardware config options (e.g. enable/disable Secure Boot,
enable/disable hardware devices etc.) that can be accessed pre-boot by
pressing a dedicated key.  If it does make changes to this, is it
possible to know in advance which options will be available after flashing?

I looked around and couldn't find anything relating to this topic.
Perhaps flashing coreboot doesn't have any effect at all on BIOS setup
options, I'm not sure.

Thanks.
