Fanoush: I GOT IT TO WORK! I rechecked my bootmenu.conf file in /mnt/initfs and noted that I had inadvertently retained an ext3 designation from your example file when I adapted it. I changed that (second) designation to ext2, put my bootable card once again in the external slot, the unconfigured card in the internal slot, then when booting up I chose the external menu item, and it booted fine. Sorry to have troubled you. Now, when I format the unconfigured card, I'll do it from the internal slot, then switch it to the external slot when the configuration is entirely finished. I'm assuming that I'm not going to be able to configure it in the external slot (unless I leave the internal slot empty???). Thanks again, Jim.
