Hi Tom: I think what you may be looking for is the rdev command. If you are going to place a kernel on a floppy then use rdev on an image to set the root device and then move it to the floppy with 'dd if=kernelfile of=/dev/fd0'. Man rdev will give you the various arguments you can use. Kirk -- Kirk Reiser The Computer Braille Facility e-mail: kirk at braille.uwo.ca University of Western Ontario phone: (519) 661-3061
