Abstract
A method and apparatus for providing configuration information is provided in a network computing environment having a plurality of hosts and at least one Gateway attachment and a channel interface, using a QDIO device. A set of special tables and commands are provided at initialization time over the channel interface which provide all configuration information. The tables can map any Host images and Host Device Addresses which will be using the QDIO Interface to the specific bits defined in a SIGA vector, the SIGA Vector giving initiative to said QDIO connected Gateway device.
