摘要： Aspects for increasing control information from a single general purpose input/output (GPIO) mechanism are described. The aspects include establishing a plurality of voltage levels to indicate a plurality of states for association with installed options on a computer system planar. Further included is the determination of which of the installed options is present via the single GPIO. An analog-to-digital (A/D) converter is also included and converts a voltage level signal indicative of installed options on the computer system planar, while a resistor network is utilized to establish the plurality of voltage levels.

摘要： A data processing system and method are disclosed for providing an access connector which limits access to a network to only authorized client computer systems. The network is controlled by a server computer system. The access connector is provided for physically coupling a client computer system to the network. The access connector is physically coupled to the network. Prior to permitting the client computer system to attempt to establish a client communication link with the network, the client computer system attempts to authenticate itself to the server computer system. In response to the client computer system being unable to authenticate itself to the server computer system, the access connector prohibits the client computer system from establishing a client communication link between the client computer system and the network.

摘要： A system and method for storing adapter card Option ROM BIOS extensions on the system's DASD and, more particularly, on a partition of the DASD that is generally inaccessible to the operating system. The system may partition the system DASD into a user partition and a hidden partition where the hidden partition is preferably inaccessible to the operating system. BIOS extensions files are stored in the hidden partition. The system BIOS, when executed, identifies the peripheral devices on the system and interrogates the hidden partition for BIOS extension files corresponding to each of the identified devices. If the hidden partition contains a BIOS extension file corresponding to an identified peripheral device, the file is verified for authenticity. If the verification completes successfully, the BIOS extension file is copied into shadow RAM and control is passed to it. In one embodiment, each BIOS extension file are downloaded to the system's DASD using a standards-based update process that is independent of the vendor or adapter card type.

摘要： A method and system are disclosed for dynamically loading selected BIOS modules and settings from a server computer system to a client computer system according to an identity of a user who is currently utilizing the client computer system. The client computer system is coupled to a server computer system via a network. Selected BIOS modules and settings are associated with a particular user. These BIOS modules and settings are those preferred by the particular user to use in order to customize the client computer system when the client computer system is used by the particular user. The associations among the particular user and the selected BIOS modules and settings are stored in the server computer system. The selected BIOS modules and settings are downloaded from the server computer system to the client computer system when the particular user causes the client computer system to start booting, i.e. when the particular user is the current user. The client computer system is then booted utilizing these downloaded BIOS modules and settings. The client computer system is booted utilizing BIOS modules and settings received from the server computer system in order to customize the client computer system according to the current user's preferences.

摘要： A data processing system and method are described for providing a dynamically assigned network address to a client computer system. The data processing system includes a server computer system coupled to the network. An access port is provided which is coupled to the network. The computer system is coupled to the network utilizing the access port. The computer system is then powered on. The computer system requires a network address in order to communicate utilizing the network. The computer system initially has no stored network address each time prior to being powered on. A dynamic network address is provided to the computer system utilizing only the access port each time the computer system is powering on.

摘要： A data processing system and method are disclosed for permitting only preregistered client computer hardware to access a service executing on a remote server computer system. A log-in token is established including a unique identifier which identifies a particular client computer hardware. The client computer hardware logs-on to the server computer system. Subsequent to the client computer hardware logging-on to the server computer system, the client computer hardware attempts to access the service. During the attempt, the client computer hardware transmits the log-in token to the server computer system. The server computer system utilizes the unique identifier included within the log-in token to determine if the client computer hardware is registered to access the service. In response to a determination that the client computer hardware is registered to access the service, the server computer system permits the client computer hardware to access the service. In response to a determination that the client computer hardware is not registered to access the service, the server computer system prohibits the client computer hardware from accessing the service.

摘要： A data processing system and method are described for permitting a portable computer to automatically detect the presence of a printer within a remote area, and responsive to the detection, automatically establishing a communications link with the printer. The portable computer is physically disconnected from the printer. The portable computer transmits a wireless query signal to the remote area. In response to a printer physically located within the remote area receiving the wireless query signal, the printer transmits a wireless reply signal to the remote area. In response to the portable computer receiving the wireless reply signal, the computer automatically establishes a communications link with the printer so that the computer may utilize the printer to print information. The communications link may be established with a printer for which the computer does not include a printer driver necessary for communicating with the printer.

摘要： A data processing system and method are disclosed for prohibiting access to a SCSI bus prior to a correct entry of an access password. The system includes a plurality of internal SCSI bus devices coupled to the SCSI bus. The system also includes an external SCSI connector for coupling external SCSI devices to the SCSI bus. The access password is established and stored within the system. The plurality of internal SCSI bus devices and the external devices are prohibited from accessing the SCSI bus prior to a correct entry of the access password. The SCSI bus includes a busy signal line. Prior to a correct entry of the access password, the system asserts the busy signal line, indicating that the SCSI bus is busy. Both internal and external devices are prohibited from accessing the SCSI bus while the busy signal line is asserted.
