Internal flashing |
after flashing coreboot |
The SPI flash can be accessed using flashrom. By default, only the BIOS region of the flash is writable:
flashrom -p internal -N -w coreboot.rom --ifd -i bios
If you wish to change any other region, such as the Management Engine or firmware descriptor, then an external programmer is required. More information about this here.
