Still another note on this. the last part for making an image won't work. The method I gave will work if you have a local machine where you make the disk floppy directly. To duplicate it you'd have to format a new floppy to 1680K, mount the image and copy the files to the new floppy.
If you want to make a more convenient, transportable floppy image, then do as above except format the floppy to 1440K (fd0u1440). the image will then be writable directly to floppy with rawrite or linux 'dd'.
This still should work for kernels up to 1417K. You should be able to get syslinucx.cfg, message.txt, and f1.txt in there, but probably not the config file. You may be able to get the system.map in by copying it in BEFORE unmounting and running syslinux. I haven't checked to be sure, but it seems that, MAYBE after running syslinux, you get 'Device Full' errors.
You can make any kernel default to booting a root floppy, but you need to be sure and set the other rdev flags first, plus have the syslinux.cfg set up for it.
Bonecrusher, I'll happily make your bootdisk available for download at amigolinux.org iy you like. I'd like, at least, to have a copy of your config file. My distro can't use 2.6.x directly, since 2.6.x doesn't support umsdos. However Amigo Linux can be easily 'migrated' to a linux partition and could then use a 2.6.x kernel. Your bootdisk might be useful for that.
