An apparatus for accelerating data transfer between a host computer and a peripheral, wherein the peripheral is compatible with IDE/ATA standards, said apparatus comprising: host interface circuitry that is compatible with IDE/ATA standards and that is connected to said host computer; means for requesting a first set of data to be transferred from the peripheral to the host interface; buffer means for storing the first set of data within the peripheral; communication means for communicating to the host interface that the first set of data is ready to be transferred from the peripheral; communication means for communicating to the peripheral that the first set of data is ready to be received by the host interface; means for tri-stating the IORead connection at the host interface so that the peripheral can drive the IORead connection; wherein said first set of data is transferred from the peripheral to the host interface as the peripheral asserts the IORead signal for each word of data sent from the peripheral; means for transferring the first set of data from the host interface to the host; means for requesting a second set of data to be transferred from the peripheral to the host interface; and means for transferring the second set of data from the peripheral to the host interface when the IORead signal is strobed by the host.
