floppy driver

[gmoney]

does anyone know a site that shows you how to make / create a generic floppy driver

[bubach]

No, but i got a bunch of snippets and the intel manuals..

thanks man

[gmoney]

but to be honest with you i was looking for more of a c++ approch to it cause im no good at asm

[bubach]

can't help you then. try downloading a couple of small os'es that other members made, and look at their source?

Converting asm into C++ shouldn't be too daunting of a task assuming your OS has some form of DMA abstraction and simple port I/O.

If I were you, I'd take a look through the various asm snippets and grab the pieces you need and apply them appropriately to your C++ abstractions. The asm should be fairly straight forward (esp. those with good comments) and if you need help, there's a bunch of good Intel opcode references online now-a-days. Should definitly be do-able.

Cheers,
Jeff

Look at my homepage and find a FD-driver in my OS, written new from scratch. Additionally You should find the:
82077AAFloppyControllerDatasheet.pdf
from Intel on the net (or contact me at

...and I will send it to You)
my homepage is:

I don't know why I had trouble with this one either.

It looks like you have to have a lot setup already with your kernel including a timing driver, possibly a scheduler, and some working memory code to copy data from the floppy to memory.

I never got this working, but I have some notes:

floppy.c

bulbach may i have a copy of your floppy source code

I sent you an email with FDD.INC from Dex4u that is heavily commented. It should help you out.
