   + It allows serving a whole iso via HTTP. Can we serve the lmde7 iso this way?
     + So far without success. It seems the efi files we prepped do not like to linux mint iso.
 
+
+### Working solution
+- Supply these cli options to vmlinuz: `boot=live live-config ip=dhcp fetch=http://192.168.0.1/lmde-7-cinnamon-64bit.iso live-media-path=/live`
+  + For legacy boot, in `pxelinux.cfg/default`
+    ```
+    DEFAULT install-legacy
+    LABEL install-legacy
+      KERNEL vmlinuz
+      INITRD initrd.lz
+      APPEND boot=live live-config ip=dhcp fetch=http://192.168.0.1/lmde-7-cinnamon-64bit.iso live-media-path=/live
+    ```
+   + For EFI (not tested yet)
+   ```
+   menuentry "LMDE 7 via HTTP ISO fetch" --class linuxmint {
+       set gfxpayload=keep
+       linux /vmlinuz boot=live live-config ip=dhcp fetch=http://192.168.0.1/lmde-7-cinnamon-64bit.iso live-media-path=/live quiet splash --
+       initrd /initrd.lz
+   }
+   ```
+- In dnsmasq config:
+```
+pxe-service=x86PC, "PXELINUX (BIOS)", "pxelinux.0"
+pxe-service=X86-64_EFI,"PXE (UEFI)","grubx64.efi"
+```
+- These files must be in tftp root (may be incomplete for efi as it was not tested)
+  + common to both legacy and efi (extract from the iso)
+    - vmlinuz
+    - initrd.lz
+  + legacy
+    - pxelinux.0 (get from debian netboot.tar.gz)
+    - ldlinux.c32
+      + Ensure the syslinux-common package is installed, then `cp /usr/lib/syslinux/modules/bios/ldlinux.c32 /srv/tftp/`
+    - pxelinux.cfg/default (checked into this repo)
+  + efi (follow https://ubuntu.com/server/docs/how-to/installation/how-to-netboot-the-server-installer-on-amd64/#set-up-the-files-for-uefi-booting)
+    - grub.cfg/default (checked into this repo)
+    - bootx64.efi
+    - grubx64.efi
