Anybody know any sample code for floppy DMA transfers?
And possibly just regular code.

Looking for code that uses the ports only instead of int 13 and int 21.
Pretty well got the IDE working, so now to the floppy.

This has some good floppy code.

Excellent reference, thank-you. The code should give me a start.

Hopefully I can use my books on DMA to understand it a bit. I personally don't think the code will work, but who knows. He disabled DMA 2 right after he set the count value, so this is why I don't think it would work.

Thanks again though,

PS: How is your OS comming? I found my little real mode switch program doesn't work too well when himem.sys isn't loaded and using hardware interrupts(like disk or the timer tick).

SolOS Floppy driver code works ok.

Thanks Bogdan, your OS is an inspiration to us all.
I like the organization of the directories on your source code.
Look forward to seeing when it gets to a stage that I would do some programming for it.
The forth thing should be interesting even though it is way off in the future.

I'll have a look at your floppy code. It is pretty long, and the floppy driver isn't a high priority for me now. The other docs will help me understand what you are doing.
