I too have found the RUNT boot image and have curiosly considered into modify it to boot USB Drives (KNOPPIX/Linux system) on computers that don't support USB booting in the BIOS. I think it's clearly possible but haven't had time to make serious effort. It boots with USB support ( from Floppy/CD?) and then waits for a moment to allow the USB drive to come available. If anyone is looking into this keep the posts coming. I think this would have real possibilities. This would make a real portable system in your pocket. And would allow you to modify pakages and drivers without remastering and burning CDs. Always adaptable and with no size restrictions.
