writing data to floppy

[mztan]

How can that be done? I need to use software interrupts right? I've been reading a lot about file system design and whatnot, but I can't figure out how to actually write data onto a floppy or a hard drive. Does someone have a simple C function for read and write?

Thanks

If you're in 16bit realmode then you can use the BIOS Interrupts:

If you're in protected mode then you will have to program the floppy disk controller directly.

you will find a C floppy driver for read/write floppy.
