 * Problemas:
   * Não consegui iniciar um sistema com GRUB em modo FDE (Full Disk Encryption). Notas do ThinkWiki sobre "On booting":
     * The X220 cannot/will not boot GPT disks using Legacy BIOS, you must setup UEFI.
     * The X220 will not boot /efi/*/*.efi unless "signed"(?) into BIOS, you have to copy it to /efi/boot/bootx64.efi.
     * Disabling the BIOS setting "USB UEFI BIOS Support" disables *all* USB booting, ie, both UEFI and legacy BIOS.
