+== Needed Files ==
+Syslinux [[http://www.kernel.org/pub/linux/utils/boot/syslinux/Testing/syslinux-3.73-pre7.tar.bz2]][[BR]]
+
+Everything below is only Needed if your following the boot method of the build.
+
+NASM [[http://voxel.dl.sourceforge.net/sourceforge/nasm/nasm-2.05.01.tar.bz2]][[BR]]
+
+== Changes for Cross-Tools Section ==
+
+This build is only required if your using the Boot Method of the build.
+
+=== Build Nasm ===
+
+./configure --prefix=/cross-tools &&[[BR]]
+make &&[[BR]]
+make install[[BR]]
+
+== Changes for Boot Section ==
+
+This build is only required if your using the Boot Method of the build. 
+You can also skip the building of Grub or Lilo.
+
+=== Build Syslinux ===
+
+make CROSS_COMPILE=${CLFS_TARGET}- installer&&[[BR]]
+install -d -m 755 /cross-tools/usr/bin&&[[BR]]
+install -m 755 mtools/syslinux /cross-tools/usr/bin&&[[BR]]
+install -d -m 755 /cross-tools/sbin&&[[BR]]
+install -m 755 extlinux/extlinux /cross-tools/sbin&&[[BR]]
+install -d -m 755 /cross-tools/usr/share/syslinux&&[[BR]]
+install -m 644 mbr/mbr.bin /cross-tools/usr/share/syslinux[[BR]]
+
+=== Configure Extlinux ===
+
+First we erase the current MBR on the disk, next we will install the MBR for Extlinux on
+the Primary Boot rive. I will assume the Primary Boot Drive is /dev/sda.[[BR]]
+
+dd if=/dev/zero of=/dev/sda bs=446 count=1[[BR]]
+dd if=/cross-tools/usr/share/syslinux/mbr.bin of=/dev/sda[[BR]]
+
+Second we will installed the Extlinux.sys file for bootup. This is the bootloader.[[BR]]
+install -d ${CLFS}/boot[[BR]]
+extlinux --install ${CLFS}/boot[[BR]]
+
+Now we will create our extlinux.conf file. Change root_device to your root partition of your
+Primary Boot Drive.[[BR]]
+
+cat >> ${CLFS}/boot/extlinux.conf << "EOF"[[BR]]
+default boot[[BR]]
+prompt 0[[BR]]
+timeout 10[[BR]]

+label boot[[BR]]
+        kernel clfskernel-boot[[BR]]
+        append rw root=root_device[[BR]]
+EOF[[BR]]
+
+== Changes for Final-System Section ==
+
+=== Build Nasm ===
+
+./configure --prefix=/usr&&[[BR]]
+make &&[[BR]]
+make install[[BR]]
+
+
+=== Build Syslinux ===
+
+Now we will build the final version of the Syslinux, and we will copy the menu.c32 file
+over so we can have a menu at bootup.
+
+make installer&&[[BR]]
+make install&&[[BR]]
+cp -ar /usr/share/syslinux/menu.c32 /boot[[BR]]
+
+=== Configure Extlinux ===
+
+First we erase the current MBR on the disk, next we will install the MBR for Extlinux on
+the Primary Boot rive. I will assume the Primary Boot Drive is /dev/sda. We repeat this
+step from above. Reinstalling this ensures us that we are using the currently built
+version of the file. When Syslinux is cross-compiled, some files are not made and
+the premade ones are. This will ensure that we use the ones we just built.[[BR]]
+
+dd if=/dev/zero of=/dev/sda bs=446 count=1[[BR]]
