paulcfs,

I experienced a similar problem creating an install that would boot and run from compact flash, but I wasn't patient enough to wait 2 minutes to see if it would find the KNOPPIX image. I don't remember the exact symptoms or what specifically I did to fix it. I do have it working, however, and it doesn't hesitate on boot. I posted my documentation in the topic "Booting Knoppix without CD and with ISO image and PH?" on this forum. You may want to look it over and see if something I did might address your problem.
