 ====== lilo bootloader ======
-LILO (Linux Loader) is a boot loader for Linux
+LILO (Linux Loader) is a boot loader for Linux and the default bootloader for non EFI slackware installs.
+we need multiple kernels to boot. whether you run stable or -current you want to always have a known working kernel to fall back on. first we will install the kernels of your choice using slackupdr
+[[https://wigums.ddns.net/dokuwiki/doku.php?id=slackupdr|slackupdr]]
+once your kernels are installed edit lilo.conf
+<code>nano /etc/lilo/conf</code>
+find the kernel stanza and we will expand it to include the new kernels. we are also going to add boot entries for huge versus generic kernels. find this stanza
+<code># Linux bootable partition config begins
+image = /boot/vmlinuz
+  root = /dev/sda2
+  label = huge
+  read-only</code>
+we will add stanzas for the kernels we've installed
+here is a default lilo.conf as generated by liloconfig
+<code># LILO configuration file
+# generated by 'liloconfig'
+#
+# Start LILO global section
+# Append any additional kernel parameters:
+append=" "
