Thanks for the tip, but it does not work. # dd if=/dev/zero of=disk bs=1024 count=6144 # ls -al -rw-r-r 6291456 disk # dd if=/dev/fd0 of=disk bs=512 count=1 -rw-r-r 512 disk # this means my image is overwritten I use coreutils-4.5.3-19 Do you have another hint for me ? Or other question for this case, if I boot from an image of my bootable floppyimage (dd if=/dev/fd0 of=image.img bs=1024) -rw-r-r 1474560 image.img How can I extend this image (without deleting) to a size of e.g. 6MB ?
