摘要： A method for using an operating system device for non-operating system uses. A false event signal is generated to indicate that a device should be shut down. After this is accomplished, the device is used for a different purpose while the operating system thinks it is inoperative. Once the other use is completed, another false event signal is generated so that the device is activated again and returned to use in the operating system in normal fashion.

摘要： Technologies to generate an error record are described herein. A method includes performing a scan of one or more error logs to identify a source of data in response to an attempt to access the data, determining whether an amount of time to complete the scan will exceed a threshold value, and generating a notice that the error record will be deferred based on the determination. A system includes a data collector to scan one or more error logs to identify a source of data in response to an attempt to access the data, a controller to determine whether an amount of time to scan the error logs to identify the source of data will exceed a threshold value, and a signal generator to generate a signal indicating that the error record is to be deferred based on the determination.

摘要： In some embodiments, the invention involves using a policy engine during boot, in the driver execution environment (DXE) phases to authenticate that drivers and executable images to be loaded are authenticated. Images to be authenticated include the operating system (OS) loader. The policy engine utilizes a certificate database to hold valid certificates for third party images, according to platform policy. Images that are not authenticated are not loaded at boot time. Other embodiments are described and claimed.

摘要： In some embodiments a Trusted Platform Module (TPM) manages a first flag that identifies whether a secure environment has ever been established. A chipset manages a second flag that identifies that there might have been secrets in memory and a reset or power failure occurred. At least one processor and/or the chipset lock, maintain a lock, and/or unlock a memory in response to the second flag. Other embodiments are described and claimed.

摘要： Disclosed is a method, apparatus, and system in which a basic input/output BIOS is run and a non-volatile memory coupled to the BIOS is read. The BIOS determines if legacy partition address data is not present for a disk partition identified in the non-volatile memory, and if legacy partition address data is not present for the disk partition, the BIOS causes the execution of a Legacy OPROM. The execution of the Legacy OPROM causes legacy partition address data for the disk partition that does not have associated legacy partition address data to be obtained. The non-volatile memory as well as the disk drive is updated with the legacy partition address data.

摘要： Methods and apparatus to enable console redirection in a multiple execution environment are disclosed. In an example method, at least one periodic interrupt in a first basic input/output system (BIOS) execution environment of a local console is initiated. Data associated with a second BIOS execution environment of the local console is retrieved. The data associated with the second BIOS execution environment is communicated to a remote terminal.
