A data processing system and method are described for permitting a server computer system to perform remote diagnostics on a malfunctioning client computer system coupled to the server computer system utilizing a network. The server computer system transmits a diagnostic command to the malfunctioning client computer system utilizing the network. A network adapter operating as a bus controller for an internal bus within the malfunctioning client computer system executes the diagnostic command. The network adapter transmits a result of the execution of the diagnostic command to the server computer system. In this manner, the diagnostic command is executed within a malfunctioning client computer system by a remote, server computer system.

A system and method for connecting a computer terminal (e.g., a personal computer) to a data transmission network with the appropriate settings for connection obtained from the network if the terminal has been moved and the settings are not appropriate for the new location. The system and method involve detecting that the terminal has been removed from the data transmission network, and, if the terminal has been moved, checking to determine whether the previous settings are appropriate for use in the new location. If the settings are appropriate, then the previous settings are used; if not, new settings for the terminal are obtained from the network, using a program such as the IBM's Dynamic Host Connection Program (DHCP), with the details on the settings (or connection) maintained at both the network and the computer terminal and updated when a new or changed connection to the data transmission network is made.

A data processing system and method are disclosed for authenticating a client computer system to a secure network prior to permitting the client computer system to attempt to log-on to the network. The secure network is controlled by a server computer system. A unique identifier is established which identifies the client computer system. The unique identifier is encrypted. Prior to permitting the client computer system to attempt to log-on to the secure network, the client computer system transmits the encrypted identifier to the server computer system. Also prior to permitting the client computer system to attempt to log-on to the network, the server computer system utilizes the unique identifier to determine whether to permit the client computer system to attempt to log-on to the network. The client computer system is authenticated prior to permitting the client computer system to attempt to log-on to the network.

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.

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.

A client on a network is provided with auxiliary low power logic, at the network adoptor, that is always active and simulates network traffic (e.g., Ethernet format) normally sent under control of the main client system processor(s). This logic collects client status information and reports to the network manager, even when the system CPU is powered down, information which allows the network manager to exercise broader control and perform maintenance and upgrades which would otherwise require a dialog with the user and/or limit maintenance and reconfiguration of the client system to off-hours activity.

A method, computer program, and system for paging platform configuration registers in and out of a trusted platform module. In a trusted computing platform, an unlimited number of platform configuration registers can be obtained through paging. The trust platform module encrypts and decrypts platform configuration registers for storage outside the trusted platform module.

When a flash unlock routine unlocks the flash memory to permit updating of a BIOS image, a message is left in secure non-volatile memory, such as a EEPROM. Upon the next re-boot, the boot block code will detect the special message in the non-volatile memory and perform a signature verification of the next block of code that is to be executed during the POST process. This code block will check the remainder of the BIOS image before POST proceeds.

The hard disk drive of a computer system is loaded with a preloaded image including an operating system, a number of application programs, and a device driver installation routine, all of which are not dependent on the hardware configuration of the computer system. A hidden partition of the hard disk drive is also loaded with a number of device drivers, which are dependent upon the hardware configuration. During the first boot only of the preloaded image, the device drivers are installed by the device driver installation routine.

A method for associating a pass phrase with a secured public/private key pair is disclosed. A user public/private key pair is first established for a user. The user public/private key pair includes a user public key and a user private key. Then, the user public/private key pair is encrypted along with a random password, utilizing a chip public key. Next, a first symmetric key is generated. The random password is encrypted utilizing the first symmetric key. A first password is generated by hashing a first pass phrase. Finally, the first password is encrypted along with the first symmetric key, also utilizing the chip public key. As a result, a user can access the user private key to perform an authentication function by providing the first pass phrase.
