Hi all,
A few days ago I wrote a small assembly program, which hangs the computer if I boot it. I wanted to test it, so I used dd to writeit in the first sector of my disk,

dd if=/home/xxx/2.bin of=/floppy/2.bin bs=512 count=1

i tried to boot with that floppy but nothing happened....

How can I put a .bin file in a floppy and make it bootable with dd?
Thnks

dd doesn't need the floppy to be mounted. Just dd to the device directly:

dd if=/home/xxx/2.bin of=/dev/fd0/2.bin bs=512 count=1

Actually, the output file should just be the disk itself.

indeed. thanks matir.

No problem. I wonder what it takes to make bootable assembly code...

Hi Matir,

I don't mean to be offtopic but since the original question was already answered I thought
I'd answer yours.

Writing a very basic bootloader is really very easy. I've played around a bit with it myself.
Instead of going through it here I found a website that explains the concept very well.

And this page is talking about writing an OS in a emulated environment which may also be
interesting to some.

I'm not sure the original posters reasons but IMO since grub and lilo are both already so good, I would just use one of them.

It's great for learning though, and that's always a good reason.

Cool, thanks for the links. As you say, all I want to do is learn.
