how to creare floppy images


hi everybody,

i am new to linux and learning kernel development and it is required to create a bootable floppy again and again which is frustrating. is there any way to create bootable floppy images directly with out making one from a real floppy so that it can tested on bochs.
if i am not wrong it is possible making links of /dev/fd0 but i am not sure how to do it.
any help is appreciated.
thanks in advance for help.

I'm just guessing, but try

cat /dev/fd0 > floppy.img

or

dd if=/dev/fd0 of=floppy.img

yeah you are right but i dont want this way.
what i want is that i create a floppy image of data on the hard disk itself, the same way as mkisofs is used to create a iso image on hard disk.
main purpose of doing is to be able to test the floppy images on bochs.

any help??
thanks in advance.

better latter than never, that's how to do this with a single floppy drive:

1) copy your data to the floppy

cd /your_data_directory
mount -t ext2 /dev/fd0 /mnt/floppy (adapt /dev/fd0 to where your floppy is located on /dev)
cp -R * /mnt/floppy

I check the data went well on to hte floppy, then

2) Make an image of the floppy :

umount /mnt/floppy
cat /dev/fd0 > /where_you_wanna_put/floppy.img
or
dd if=/dev/fd0 of=/where_you_wanna_put/floppy.img
As dracolich said

3) Copy the floppy image to another floppy :
cat /where_is_your/floppy.img > /dev/fd0
or
dd if=/where_is_your/floppy.img of=/dev/fd0
