My X230 tablet Coreboot rom
first time flash: Flash the corresponding bios chips with these commands. Keep in mind that if you don´t use ch341 programmer (Beaglebone or Rpi) you have to swap the name of the programmer.
sudo flashrom -p ch341a_spi -w top.rom
sudo flashrom -p ch341a_spi -w bottom.rom
to flash (with coreboot already installed):
sudo flashrom -p internal:laptop=force_I_want_a_brick -w name_of_the_rom.rom
