Are there any good floppy disk tutorials

[earlz]

I have looked all over and have not seen 1 floppy disk tutorial
all i have seen is datasheets which are quite hard to understand IMHO

edit:
i am using protected mode with no bios

Here is the pmode floppy driver from Dex4uOS
http://www.dex4u.com/images/FloppyDriver.zip
Here is a pdf doc on the floppy controler, by intel
http://www.osdever.net/documents/82077A ... ?the_id=41
You will find the above source code commented to go with the pdf flowcharts, the pdf will tell you what needs to be done and the code will show you how to do it.
The above code is self contaned and only needs linking into you timer and floppy IRQ, for it to work.

Also when searching for the PDF this link came up may help: http://inglorion.net/documents/tutorial ... ut/floppy/

Thank you so much

I'm not a big asm coder but this is easy to understand thanks to the function info

edit:
I'm having a bit of some problems

i am getting @@ redefined and the little macros you made in fddinfo are giving a parser error


edit2:
Because nearly all of my OS is C i am converting it to C
plus i will learn what it does better

Dex4u: You might want to add a link to your implementation to "Reference Implementations" and link that FAQ page when the topic comes up again.
