ok, basically I am compiling a kernel and some modules, then I intend to boot it. The instructions here are what I'm trying to follow but they don't work. I've only gotten as far as compiling the kernel.

Exactly what instructions do not work for you?

Are you on a 32-bit or 64-bit OS?

I'm on a 32-bit system and basically all the instructions work, except for the fact that the image does not boot. qemu just seems to not even recognize the image as being bootable.

How are you checking to ensure that you have a bootable image? What is the output of
Code:
dd if=<your image> bs=512 count=1 | xxd

I used the instructions given by corona688 an obtained an image that produced this when executing the command:

Code:
#dd if=the_image.img bs=512 count=1 | xxd

But like I said I need to add files to the image, because I want to boot a kernel. However, this method does not allow me to do so.

What I usually do, instead of building bootable things from scratch, is adapt existing ones. I usually use boot ISO's, not floppies, since they can actually hold an entire kernel. Give me a bit and I'll craft an example for you.

Old 01-04-2011
That's a good option, but I'll still like you to tell me how to make one. But if you can make one for me just for me to get my project going I'd appreciate it. Here are the files to be included:
