I have started an OS project. I have created a simple real mode bootloader. I am still to learn coding PM and kernel. I want to use a floppy image file to store my bootloader and kernel. I have created a qemu-img file. I want to format the image file with FAT12 for which I want to write a FASM code. I have read documents on floppy disk geometry but I am looking for some example code to learn from it.

Whole operating system is in 16-bit code.

ksanjeet, I have published my old mkfloppy sources
here for some days. Search for keyword "mkfloppy" on this forum for examples.
Edited. Link updated.

It depends on the operating system that you are using. I'd recommend you check out the build scripts for MikeOS.

Thanks everyone.
MikeOS is proving to be a great help.
So far, I am using OS tools to format the images. I want to write my own code to format images.
I have downloaded ego's code from the link and will try to learn from it. Thanks and I really appreciate everyone's help.
