Problem with floppy. [solved]

[petrusss]

I'm trying to read some data from the floppy, I get contact and such, but when I try to read from the floppy I see that all the values below is 0!
FDD: st0 0 st1 0 st2 0 Cylinder 0 Head 0 Sector 0 Sector size 0.

I looked in the bochs log, this is what I found:

Code: Select all

00081379435e[DMA  ] write to command register: value(10h) not 0x00
00081379450e[DMA  ] write to command register: value(10h) not 0x00
00081550370e[FDD  ] io_write: 0x3f5: invalid floppy command 0x06

Do you have a clue about what I'm doing wrong?

Are my definitions wrong?

Code: Select all

#define FDC_CCR              0x3F7
#define FDC_DOR            0x3F2
#define FDC_DATA           0x3F5
#define FDC_MSR            0x3F4

And one question more: how many sectors are there per track on a floppy?

Here's the code:

OOPS!
Sorry!
I solved it Data should pass through the data-register.
I practicised some english anyway.
