    41     <note><para>Most newer systems now come with system firmware that is in
    42     UEFI (Unified Extensible Firmware Interface) mode by default. To boot LFS
    43     on these systems using the instructions here, the UEFI Mode and Secure Boot
    44     capabilities need to be turned off. There are ways to boot with these
    45     capabilities still enabled, but then are not covered here. For details,
    46     see <ulink

     43        To boot LFS on host systems that have UEFI enabled, the kernel needs to
     44        have been built with the CONFIG_EFI_STUB capabality described in the
     45        previous section.  However, LFS can be booted using GRUB2 without such
     46        an addition. To do this, the UEFI Mode and Secure Boot capabilities in
     47        the host system's BIOS need to be turned off.  For details, see <ulink
