Abstract: The present disclosure provides a network architecture and verification platform for analyzing the various modules of a Unified Extensible Firmware Interface (UEFI) firmware image. In one embodiment, the disclosed network architecture and verification platform obtains various UEFI firmware images, such as UEFI firmware image residing on a client device or a UEFI firmware image hosted by a hardware manufacturer. The network architecture and verification platform may then segregate the various UEFI firmware modules that make up the UEFI firmware image, and subject the modules to different types of analysis. By analyzing the UEFI firmware modules individually, the network architecture and verification platform builds a repository of Globally Unique Identifiers (GUIDs) referenced by a given UEFI firmware module, which may then be referenced in future analyses to determine whether any changes, and the extent of such changes, have been made to an updated version of the given UEFI firmware module.

Abstract: A system, method and computer program are provided in an installable file system (IFS) for a network server for enabling access to and distribution of Audio CD information over a client server network by creating a virtual directory of computer audio files from Table of Contents information read in raw sector mode from an audio CD in a CD-ROM drive, which virtual audio files appear to the server's operating system as normal files stored on a convention file system.

Abstract: The performance of a DASD having a data cache and at least one set of R/W heads is improved by implementing a replacement policy which, upon determining that a request for data in the DASD requires replacement of a data in a data cache buffer, selects cache data corresponding to data which is cheapest to retrieve from the DASD in view of a location of the DASD R/W heads and replaces the selected cache data with the requested data, thus keeping the cache filled with data which is least expensive to retrieve from the DASD. Data in the DASD is updated from the cache when it is inexpensive.

Abstract: Disclosed is a technique for overcoming the 1-Mbyte mode memory limitation associated with "real-mode" operation of certain Intel Corp. microprocessor architectures. This limitation can be overcome by altering the contents of a register portion that is computationally meaningful only in "protected mode," but which persists and exerts effects in real mode. By indirectly manipulating the contents of this register portion in protected mode in a manner that avoids disruption to the register during the switch back to real mode, access can be obtained, in real mode, to up to 4 Gbytes of volatile memory.
