-=====.configs=====+=====building coreboot for x230 with FHDmod=====
  
-FIXME allow txt file upload, plz!+These steps should create a bootable coreboot-image for the x230 with seabios.
  
-tbd+:!: This image will only work with a the FHD-mod.
  
 +:!: LVDS-output will not be available.
 +
 +If/when the fhd-mod gets accepted into coreboot, you can skip steps #2 & #3.

 +git rebase master FETCH_HEAD
 +
 +# 4. get the submodules
 +git submodule update --init --checkout
 +
 +# 5. build coreboot crosscompiler environment (may take a while)
 +make crossgcc-i386 CPUS=4
 +
 +# 6. create x230 specific defconfig (remove comments in the last 5 lines if you want to add optional secondary payloads)
 +cat << EOF > config/defconfig
