I checked out edison in poky in meta-intel and built core-image-minimal for n450. By default it builds GRUB 2, which after install boots to a GRUB prompt with no menu. Using the PREFERRED_PROVIDER method above with the edison branches results in a GRUB 1 menu after install. -- Darren > > Tom > >> The answer might be "we need for time than is available in the 1.1 >> release to fix it" but I'd at least like to see the answer to the >> question before we start with workarounds. >> >> Cheers, >> >> Richard >> > > -- Darren Hart Intel Open Source Technology Center Yocto Project - Linux Kernel
