Abstract: An information handling system scans an extensible firmware interface system partition for a file path. If the file path is missing, the system determines information associated with the file path, and adds an entry in an extensible firmware interface system resource table based on the information associated with the file path.

Abstract: An embedded controller locks down one or more devices within an information handling system based on a detection of an operating system crash. A processor monitors an operating system executing within the information handling system, and detects the operating system crash. In response to the detection of the operating system crash, the processor notifies the embedded controller of the operating system crash.

Abstract: A method for updating firmware on a device in an information handling system in a resilient manner is described. The method includes receiving a new firmware for updating a device; storing a current firmware image or a working copy of the current firmware of the device in a volatile memory; updating the device with the new firmware after storing the current firmware in the volatile memory; setting a first boot flag to perform diagnostics at a next reset of the information handling system based on updating the device with the new firmware; and determining, by the information handling system at the next reset in response to the first boot flag, whether the device satisfies at least one criteria indicating the new firmware is operational on the device. An information handling system that includes the device and performs the method is also described.

Abstract: An information handling system includes top and bottom housings, multiple fixed locking magnets secured within the bottom housing, multiple movable locking magnets located within the top housing, and a contracting wire in physical communication with each of the movable locking magnets. The contracting wire shrinks in length based on a voltage being applied to the contracting wire. The contracting wire exerts a force on each of the movable locking magnets as the length of the contracting wire shrinks. Each of the movable locking magnets transition from a locked position to an unlocked position based on the force exerted by the contracting wire. The top and bottom housings separate when each of the movable locking magnets are in the unlocked position.

Abstract: An information handling system includes a display device and a processor. The display device outputs pixels associated with a text font. The processor converts red, green, blue (RGB) pixels to image perspective transformation (IPT) pixels. The processor further sharpens one or more of the IPT pixels that do not have color. The sharpening of the one or more of the IPT pixels identifies edges of the text font and defines widths of the text font. The processor corrects edge overshoot and edge undershoot created by a digital filter. The edge overshoot and the edge undershoot are corrected for each IPT pixel associated with the text edges. The processor also reduces noise enhancement in the sharpened IPT pixels, retains grey text portions of each of the sharpened IPT pixels, and converts the IPT pixels to new RGB pixels. The processor outputs the new RGB pixels to the display device.

Abstract: An off-host authentication system includes an authentication information handling system (IHS) that is coupled to a network. The off-host authentication system also includes a host processing system. An off-host processing system in the off-host authentication system is coupled to the host processing system and is coupled to the authentication IHS through the network. The off-host processing system provides an encrypted primary authentication item to the authentication IHS through the network. The off-host processing system then receives an encrypted secondary authentication token from the authentication IHS through the network. The off-host processing system then decrypts the encrypted secondary authentication token to produce a decrypted secondary authentication token and uses the decrypted secondary authentication token to retrieve a tertiary authentication token. The off-host processing system then provides the tertiary authentication token to the host processing system for use in logging a user into a user IHS that includes the host processing system.

Abstract: An encryption key management system includes an encryption IHS that is coupled to a network. The encryption key management system also includes a host processing system. An off-host processing system in the encryption key management system is coupled to the host processing system and is coupled to the encryption IHS through the network. The off-host processing system provides an encryption key request to the encryption IHS through the network, receives an encryption key from the encryption IHS through the network and stores the encryption key, provides the encryption key to the host processing system in response to authenticating a user, and revokes the encryption key in response to a revocation instruction received from the encryption IHS through the network. The providing the request, and the receiving, providing, and revoking the encryption key may be performed by the off-host processing system while the host-processing system is not in an operating mode.

Abstract: An off-host authentication system includes a network. An off-host processing system is coupled to the network and sends an encrypted authentication item through the network in response to validating a user. An authentication information handling system (IHS) is coupled to the network and receives the encrypted authentication item from the off-host processing system through the network, decrypts the encrypted authentication item to produce a decrypted authentication item, validates the decrypted authentication item, and sends an approval message through the network. A directory system is coupled to the network and receives the approval message through the network and, in response, sends a user approval through the network. A host processing system, which is located in a user IHS that includes the off-host processing system and which is coupled to the network, logs a user into the user IHS in response to receiving the user approval through the network.
