Abstract: A computer device driver comprises a computer operating system including a structure configured to communicate with a device driver interface using a predefined protocol, and a device including a memory storing an embedded driver with device information. In one aspect, the memory is configured to store physical information and functional information regarding the device. In another aspect, the operating system is configured to import at least a portion of the device information and build a device driver. In another aspect, the memory is configured to store a driver for each of a plurality of operating systems. Advantages of the invention include flexible device driver implementation and deployment across a wide range of computing operating systems and environments.

Abstract: A peripheral device to generate read and write cycles on a PCI bus comprises a PCI bus interface. A control unit has a data pattern generator to source a data pattern to a target via the interface during a write operation and to verify an incoming data pattern from the interface during a read operation.
