IDENTIFY is often a "special case" command, > and rarely, if ever, uses IORDY. I think you misunderstand the EDMA IORDY timer, The EDMA IORDY register defines the timeout when doing PIO data transfers and the data is not ready, for example, when doing PIO read, the CPU will access the data register to fetch the data from internal fifo, in case that fifo is emptied for too long time (the data stopped to come), the HW will release the CPU to prevent hanging the system. saeed -- To unsubscribe from this list: send the line "unsubscribe linux-ide" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
