Abstract
A method and apparatus for reducing the disk drive data transfer interrupt service latency penalty is described. The method comprises beginning a data transfer between a disk drive and a host system, issuing an interrupt before the transfer is complete, and then completing the data transfer. This method may be implemented on a computer assembly that includes a processor, an input/output controller, and a scatter/gather list, which is stored in memory, that includes an entry that will cause the input/output controller to generate the interrupt.
