OSDev.org

OK my OS is good and working!, but until now I have been ruining it live with no file system I know what I'm doing, but I have never worked with file systems if anyone know any good sites that can teach me FAT32 and how to use it in my OS that would be great or any other pointer or examples thanks

Before you decide to use fat32 you may want to ask yourself, on which media I'm working? Because it's a bit difficult (and pointless) to fit a fat32 on a floppy. If you are working with hard disks this is better. I suggest you the brokenthorn tutorials. They are on fat12 but it explain well how fat works and than it is easy to write fat16 and fat32 drivers. You may want to write also a long name support. In this case I suggest you the specs in the osdev resource center (notdot.org i think).

Yes I will be working with HD and Live/installation CD's

For CDs, you will be working almost exclusively with the ISO9660 filesystem, sometimes with various extensions for additional functionality (El Torito, Juliet, etc).
