The timing in Bochs can be funky. In my bxrc file, I have set the IPS to 4000000 and the clock synchronization method to realtime, if that helps.

Hi guys, i'm solved executing 'sti' into reading floppy and DMA. I think that problem is due to hardware interrupts for the activation of devices, in fact using the instruction 'sti' activates the IRQ lines, creating a device driver :D . Thanks all for your help. :wink:
