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. _______________________________________________ coreboot mailing list -- coreboot@coreboot.org To unsubscribe send an email to coreboot-leave@coreboot.org
