How to write a file system in assembler for your OS 16 bit?

Question

Operating Systems

So I wrote a bootloader, connected the kernel (there is nothing in the kernel yet except text output), now I want to write a file system and generally figure out what it is for and how it works, if anyone can, tell me the resources where you can read about it, well, if not too lazy , then tell yourself)))
Please answer the question.

Answer 1

Try to implement FAT16 support first. Start with the basics.

PS In my distant youth, ~96, I studied assembler from the book "Pravets-16". In particular, he wrote a resident to encrypt floppy disks (if my memory serves me, the sequence of reading sectors on a track can be set programmatically, moreover, there is a lot of interesting information in one of the service sectors). I screwed up the floppy disk while I learned it - there are two packs :) You can only find floppy disks in the museum now - so start with FAT16.
