+                    D16 and D8 doesn't boot with GRUB payload, see

+                    - workaround: seabios as main payload, compress grub and put that in cbfs too, configure
+                    seabios with 0s delay (no interface) and set it to boot grub from cbfs by default.
+                    Some notes, courtesy of tpearson on IRC:<br/>
+                    <strong>create a binary file with the single byte value numeric 0 in it, then add it to CBFS as 'etc/show-boot-menu'</strong> for 0s delay.<br/>
+                    <strong>compress grub.elf with cbfstool and have seabios load that, or grub-mkstandalone can compress the resulting GRUB image<br/>
+                    <strong>Create a text file in CBFS called &quot;bootorder&quot;, contents &quot;/rom@img/grub2&quot;</strong><br/>
+                    <strong>Use cbfstool to add the GRUB ELF image as a raw file with name &quot;img/grub2&quot;</strong>
