20080244252 | USING PROTECTED/HIDDEN REGION OF A MAGNETIC MEDIA UNDER FIRMWARE CONTROL - A method and firmware for accessing a protected area of a magnetic storage device via firmware control. During early system initialization, various firmware components are loaded and executed to initialize a computer system. These firmware components include a firmware driver for accessing magnetic storage devices connected to the computer system. The system firmware enables a protected area on a magnetic storage device's media to be accessed under firmware control. After firmware accesses, the protected area is closed from access by non-firmware entities (e.g., operating systems) by “hiding” the true size of the media such that those entities are unaware of this area of the media. Mechanisms are disclosed for providing firmware access to the protected area only during pre-boot, and for both pre-boot and run-time operations. The firmware-controlled media access scheme may be used to load firmware stored on magnetic media during pre-boot and to store system information in the protected area during pre-boot and/or run-time operations. | 10-02-2008 |
20090240963 | Distributed advanced power management - Power management commands from virtual machines (VMs) in a VM environment may be trapped by a VM monitor. Depending on the current power states of the other VMs in the VM environment, the VMM may emulate increase or decrease in available resources as applied to the VM issuing the power management commands. The VMM may modify the actual hardware resources available in a platform when such modification may not affect the current power states of the VMs in the VM environment. | 09-24-2009 |
20090282486 | PRE-BOOT FIRMWARE BASED VIRUS SCANNER - The present disclosure relates to allowing the utilization of a virus scanner and cleaner that operates primarily in the pre-boot phase of computer operation and, more particularly, to allowing the utilization of a virus scanner and cleaner that operates primarily during the loading of an operating system. | 11-12-2009 |
20110271347 | PRE-BOOT FIRMWARE BASED VIRUS SCANNER - The present disclosure relates to allowing the utilization of a virus scanner and cleaner that operates primarily in the pre-boot phase of computer operation and, more particularly, to allowing the utilization of a virus scanner and cleaner that operates primarily during the loading of an operating system. | 11-03-2011 |
20120163602 | Method and Apparatus for Providing Seamless File System Encryption from a Pre-Boot Environment Into a Firmware Interface Aware Operating System - Methods and apparatus for providing seamless functionality in a computer are disclosed. For example, an encrypted file system manager is included to layer an encoded File Allocation Table on top of a disk and to pass to the operating system an Embedded Root Key to provide access to an encrypted Firmware Interface System Partition. | 06-28-2012 |
20130205395 | PRE-BOOT FIRMWARE BASED VIRUS SCANNER - The present disclosure relates to allowing the utilization of a virus scanner and cleaner that operates primarily in the pre-boot phase of computer operation and, more particularly, to allowing the utilization of a virus scanner and cleaner that operates primarily during the loading of an operating system. | 08-08-2013 |
