just wanted to know if anyone has found it useful ?
or if anyone else has gotten it to work or has had trouble with it ?

[Pype.Clicker]

it seems fine, but i didn't found the time to test it in my OS already ...
anyway, it seems there's a missing stuff with include files (io.h, common_types.h, etc )

I might test it when I get my IDT working and my C++ kernel out the door ( changed plans... C++ first with a better printf and THEN a IDT. )

[ncsu121978]

you should have a working idt tom since you kept emailing me asking me for my code and i finally sent it to you

[Tom]

That's the one I'm about to test tonight!

So what's the problem ncsu121978 ?????

[ncsu121978]

well you can tell me what it is doing (or not doing as the case may be).....b/c i am honestly not going to look through all those source files you put in that zip.

make sure you have interrupts enabled....
make sure you run floppy_init() somewhere before you try to use it.
make sure you install the floppy interrupt which is IRQ6 and from within the isr call the floppy_interrupt_handler().....because the init function doesnt install a handler for you.....either install the handler to be this function, or call this function from your own handler

I've putted the right functions in the interrupt handler. The floppy drive stops after 2 seconds (so that's ok). I'm trying to read a sector by :

y=(char*) kmalloc(512*sizeof(char));
floppy_read_block(0,1,y);

And there, there is nothing at y...
More;, I've found that the int floppy_getbyte() always returns -1 !!!

[ncsu121978]

make sure you set all the timeout values according to your timer interrupt frequency
right now mine runs at 100 Hz so alot of the values i set depend on that
also the getbyte always returning -1 means that the function timed-out before there was a byte to read....again this might have something to do with your timer running at a different frequency then mine

[Zi]

It doesn't work again... I've putted the same frequency as you, and putted all like in your OS, but floppy_getbyte() returns -1 again... Or do you have some documentation to make floppy drivers ?
