    Abstract: Method and system aspects for securely transferring a computer system are described. A computer system is disabled at a shipping point via an RFID (radio frequency identification) interface and re-enabled at a receiving point via the RFID interface. Disabling the computer system includes selecting a boot password, writing the boot password to storage in the computer system via the RFID interface, and setting a disable bit in the storage via the, RFID interface. Re-enabling the computer system includes entering the boot password via the RFID interface and clearing the disable bit.

    Abstract: A data processing system includes a processor for accessing a memory in either a direct mode or an indirect mode. The memory includes at least two memory banks and two decoders for decoding bank addresses. The decoders produce bank select signals. In direct mode, the decoder outputs are generated according to which bank is addressed. In interleave mode, the two decoder outputs are ANDed to select both banks covering the address range of the selected banks.

    Abstract: A data processing system includes a memory controller for accessing a dynamic memory having a plurality of SIMMs that differ in size and speed of operation. The memory controller is operable in response to a request to access a given SIMM to read a SIMM definition register and dynamically produce memory access signals in accordance with the timing requirements of the particular SIMM being accessed. Such signals are set each time a SIMM is accessed. The signals provide different clock periods of RAS precharge time, RAS to CAS time, and CAS pulse width.

    Abstract: A wireless network access point is described which provides the resources of a backbone network to wireless clients. The access point is able to detect a degraded condition on the backbone network. Upon detecting the degraded condition, the access point transmits or broadcasts a reassociation request to one or more clients associated with the access point. In addition, the rate at which new associations are made is halted or reduced during the degraded backbone condition. In one embodiment, the association rate is reduced by increasing the interval between beacons transmitted by the access point which identify the access to the backbone network.

    Abstract: A data processing system and method are described for permitting a server computer system to remotely access asset information stored within one of a plurality of client computer systems. The client computer systems are coupled to the server computer system utilising a network. Asset information is stored in a storage device within the particular client computer system. The asset information includes information identifying a plurality of components of the client computer system. The server computer system transmits a message to the client computer system while the client computer system is powered-off. A network adapter is included within the client computer system. The network adapter accesses the storage device to obtain the asset information while the client computer system is powered-off.
