o in the default n8x0 bootmenu.conf, the external SD card defaults to ext3. Was that intentional? It caught me out as I was using Milhouse's clone script which defaults to ext2. Changing it in bootmenu.conf worked fine, of course
o timeout: changing MENU_TIMEOUT in bootmenu.conf (and reflashing) seems to have no effect, for me. Whatever it's set to (e.g 15, 20, 30), I only get about 1/2sec to hold down MENU before it boots the default flash.
