Embodiments provide a data processing system comprising first initialisation software to initialise the data processing system, means to access storage comprising a first region and a second region comprising first software; the system further comprising second initialisation software arranged, using information associated with the second region, to access the second region to launch the first software.

Data processing system and method

A system () and a method () for managing boot errors. When errors occur during boot, the errors may be recorded in non-volatile storage (). The errors in the non-volatile storage () may be retrieved, decoded, and displayed in a form more understandable to the user. Also, tie errors may be analyzed to efficiently detect and correct the causes of the errors. In addition, the analysis may be used to prevent errors altogether.

Managing boot errors

The present invention relates to a method of operating a data processing system, having a system context, comprising a first storage medium having a current system memory context, which includes data relating to the system context, and a second non-volatile storage medium; the system being operable in a plurality of states, each state having an associated level of system power consumption; and a power management system for saving the current system memory context to the second non-volatile storage medium in preparation for entering at least one of the plurality of states; the method comprising the steps of: storing an indication of whether the system has been shutdown correctly or incorrectly; outputting, during a working state of the plurality of states, data representing at least a portion of the current system memory context for storage on the second storage medium; determining, upon initialisation of the system, from the indication of whether the data processing system was shutdown correctly or incorrectly that the data processing system was shutdown incorrectly and recovering, in response to that determination, the data from the second storage medium and restoring the system memory context using the recovered data.

Data processing system and method for data transfer to a non-volatile memory in case of power failure

Devices connected to a communications bus are selectively accessed to the bus that communicates between one or more devices and a host machine. On the basis of analyzed device characteristics, communication between the device and the host machine via the bus is enabled or disabled. Filtering software intercepts the results of a GET_DESCRIPTOR function and compares same with the contents of a disallowed device characteristic list. If the device is disallowed, data flow is remapped to a generic driver which halts configuration or communication on the bus. Alternatively, configuration/communication on the bus is halted for that device.

Bus function authentication method, apparatus and computer program

The present invention relates to a data processing system method and, more particularly, to a system and method for manipulating CMOS parameters that are stored within a CMOS memory, via a user interface other than the conventional BIOS set up program. Embodiments of the present invention use a Root System Description Table Pointer as prescribed by the Advanced Configuration and Power Interface specification to read an operating system accessible table contained within conventional memory. The table stores access data to allow access to at least a subset of the BIOS CMOS parameters. Advantageously, since the access data for the CMOS parameters are stored within conventional memory, a user interface that is more sophisticated than a conventional BIOS set up program user interface can be used for manipulating those values. Still further, tokens are used to present a system independent way of representing the CMOS parameters to higher level programs. These tokens may remains constant regardless of underlying changes to the CMOS parameters.
