Hi guys, i'm trying create a floppy driver. Why doesn't access to the DMA buffer? I rely on you.

FDC code

Thanks all

Up!

Please don't kick posts like that; not only is it rude, there really isn't any need to do so, especially after only four hours. The traffic on this forum isn't so great that your post is going to get lost after a few hours, and frankly, most of the regulars here would not have had time to read your post yet. In the time since you posted, only two other threads had been posted to, so anyone able to give a useful answer to your post would have been able to see it easily enough.

Also, please be more detailed in your questions.

Because is the only question that i haven't received answer... anyway my question is clear, i wrote a floppy driver but i have problems to the DMA, in real mode is fine but not in protected mode. I thought to the 'interrupt handlers', can this be the problem of the failure? Or nothing to do? I already posted the code before.

I took a look at your question, and it violates forum rules. I took a look at your code and it violates all the basics about bootloaders - including undefined registers and writing into reserved memory.

Please use your mandatory week off to actually read the forum rules and all the documentation, and learn to be patient.
