* __microcode update__: revision `20` from 2018-04-10 (includes mitigations for Spectre Variant 3a and 4)

### release images to choose from
We release multiple different, but _very similar_ images you can choose from.
They all should work on all versions of the X230/X230T. These are the
differences; (xxxxxxxxxx stands for random characters in the filename):
* `x230_coreboot_seabios_xxxxxxxxxx_top.rom` includes the _proprietary_
[VGA BIOS](https://en.wikipedia.org/wiki/Video_BIOS) from [Intel](https://www.intel.com/content/www/us/en/intelligent-systems/intel-embedded-graphics-drivers/faq-bios-firmware.html)
which is non-free software. It is executed in "secure" mode.
* `x230_coreboot_seabios_free_xxxxxxxxxx_top.rom` includes the
[VGA BIOS](https://en.wikipedia.org/wiki/Video_BIOS)
[SeaVGABIOS](https://www.seabios.org/SeaVGABIOS) which is free software.
While technically more interesting, visually this is currently not as
beautiful:
* The [bootspash image is not shown](https://github.com/merge/skulls/issues/59).
* Early boot console messages (after your HDD's bootloader has started a kernel) might be [missing](https://github.com/merge/skulls/issues/46).

sudo ./external_install_top.sh -k <backup-file-to-create>
Select the image to flash and that's it. The image named "free" includes
[SeaVGABIOS](https://www.seabios.org/SeaVGABIOS) instead of
[Intel's VGA Bios](https://www.intel.com/content/www/us/en/intelligent-systems/intel-embedded-graphics-drivers/faq-bios-firmware.html).
Select the image to flash and that's it.
Keep the backup safe, assemble and
turn on the X230. coreboot will do hardware init and start SeaBIOS.
