After a reset on a bus, the topologies of nodes on the bus before and after the reset are accessed to identify nodes that are new to the bus. A host identifies itself in both the new topology data and the old topology data. Referring to the connectedness between ports of a node and other ports in the new topology, similarly connected nodes in the old topology are identified as matching. Identifying data present in the old data can be assigned to the corresponding node in the new data. Any nodes in the new tree lacking a matching node will require requests over the bus to obtain its identification data.

Method and program code for identifying new nodes on a bus following a reset

A method for linking work requests in a work queue with entries on a queue of completed requests. For each work queue, a tracking list is created. Each tracking list is linked to one queue of completed requests. When a work request is added to a given work queue, an entry is added to the associated tracking list. The entry in the tracking list contains all of the information needed to uniquely associate a completion queue entry to the work request that caused the completion queue entry. When a completion queue entry is retrieved from the completion queue, the tracking list for the work queue is searched for an entry corresponding to the completion queue entry. The work request that caused the completion queue entry is then identified from the information in the tracking list entry.

A system for permitting remote user access to regions of memory that have been exported for remote direct memory access purposes. The system supports dynamically changing access privileges to remote users without requiring intervention from an operating system. The system may include a memory region table and a memory window table for supporting address translations. Entries in the memory window table may include a region remote access key and a window remote access key. The memory region table may include fields for a physical address, an access value, a protection domain value, and a length of memory region.

A method of reading configuration ROM in a serial bus device reads only portions of the ROM that are organized in a directory structure. Typically, the configuration ROM follows the IEEE 1212 and/or 1394 standards and uses an IEEE 1394 bus. Based on the information read from the configuration ROM, a connecting computer can determine the appropriate device driver to use for communications with the device.

Methods, systems, and software for installing and operating selected software applications on a client computer that is in communication with a server computer on a computer network is described. In one aspect, a method for installing and operating a selected software application on a client computer that is in communication with a server computer across a computer network. In one embodiment, browser software is provided on the client computer that includes a browser user interface and is effective to identify and download selected software applications from the server onto the client computer for execution thereby. A data transfer communication link is established between the client and server computers across the network, a desired software application is selected using the browser, and the desired software application is transmitted across the network from the server to the client. The browser user interface is then transmuted into the user interface of the desired application to allow operation of the downloaded software application using the transmuted browser user interface. Using the methods, systems, and software described herein, software can be distributed to client computers without the installation and other management difficulties common with managing software on multiple computer systems. More importantly, the methods, systems, and apparatus provided by the present invention allow for the distribution of software that is platform-independent; thereby freeing network and system administrators--and users--from the frustrations and difficulties created by the need to manage various platform-dependent versions of software.
