ABSTRACT:
The invention relates to a method for computer signal processing data and command transfer over an interface and more particularly to a communication between peripheral firmware and a host processor or Basic Input/Output System (BIOS) on a Peripheral Component Interconnect (PCI) bus. In one embodiment, a device and method for reducing the load on the PCI Bus is described. In yet another embodiment, a device and method is described for constructing a variable length command block comprising message frames and aligning all message frames for a particular command block that are contiguous in memory.
