All of what I can see is after reading data, ide_transfer_start and de_set_irq are called, but then what? how data will go to the RAM? if data will be copied to the RAM implicitly through the interrupt, then where can I find the ultimate function that copies the data to the RAM. Can any body answer my question? it will be very appreciated. Thanks, ...Mohammed --
