Abstract: A method and system for bootstrapping a processor from a volatile memory device connected to the processor is disclosed. The first processor is bootstrapped from flash device. The reset lines of the second processor are asserted. The boot code for the second processor is loaded from the flash device into the volatile memory device. The reset lines of the second processor are de-asserted, wherein the processor then boots from the boot code stored in the volatile memory device. The same boot strapping method can be extended to multi-drop systems where number of secondary processor can be more than one. A switchable means for the second processor to boot from volatile memory as described or from flash memory. A method also describes a mechanism to boot from synchronous volatile memory devices.

Abstract: A method and apparatus for temporarily deferring transmission of packets/frames to a destination port in a buffered switch is disclosed. When a request for transmission of at least one packet/frame to the destination port is received, it is determined whether the destination port is available to receive the at least one packet/frame. The transmission of the at least one packet/frame is deferred when the destination port is not available to receive the at least one packet/frame. The packet/frame identifier and memory location for each deferred packet/frame is stored in a deferred queue and the process then repeats for the next packet/frame. Periodically, the apparatus attempts to transmit the packets/frames in the deferred queue to their respective destination ports.

Abstract: An apparatus and method for domain name services (DNS) for resources in a mainframe environment. The apparatus includes a locally managed DNS server and a DNS protocol to allow a client to request a mainframe resource. In response to the request, the DNS server returns the selected address of a client. Furthermore, the DNS server chooses an available resource most capable of handling the request based on resource performance characteristics.
