  • Patent number: 11010152
    Abstract: Systems and methods to stage firmware capsule package for an external device in a firmware client system. The firmware client system may include a basic input/output system (BIOS) and an operating system (OS). The BIOS may create a virtual device. The OS may download a virtual device driver package associated with the virtual device from an update service. The virtual device driver package may include a first virtual device driver and a first external device firmware. The OS may also install the first virtual device driver of the virtual device driver package, stage the first external device firmware on a storage device, and execute the first virtual device driver. The first virtual device driver may, when a first external device associated with the first external device firmware is available, deliver the first external device firmware to the first external device using an update firmware mechanism.

  • Patent number: 10971114
    Abstract: Upon detection of a change in resolution from a first resolution to a second resolution, one or more user interface elements may be dynamically scaled based, at least in part, on the detected change in resolution. The user interface elements may be dynamically scaled in such a way as to maintain an aspect ratio of each of the user interface elements while adjusting a resolution of each of the user interface elements to the second resolution. After the user interface elements are dynamically scaled, a user interface, at the second resolution, may be presented on a display of an information handling system.

  • Patent number: 10838785
    Abstract: A BIOS of an information may transmit information regarding events detected by the BIOS to an OS of an information handling system for logging in an OS event log. A BIOS of an information handling system may detect an event and may log information regarding the event in a memory of an information handling system. An OS of the information handling system may retrieve at least a portion of the information regarding the event from the event log and may add at least a portion of the retrieved information to an OS event viewer.

  • Publication number: 20200334045
    Abstract: Systems and methods are provided for supporting use of system BIOS components (e.g., such as BIOS debug messages, debugger firmware, UEFI drivers, etc.) that are stored separately from the remainder of system BIOS firmware for an information handling system. The system BIOS components may represent only a portion of the total BIOS firmware, and may be selectively retrieved and loaded from the separate storage into system memory when needed by the system BIOS for operating purposes (e.g., such as debugging operations).

  • Patent number: 10795769
    Abstract: The identification and loading of an appropriate service operating system can be facilitated when a main operating system fails. To facilitate the identification of which main operating system failed, an agent can create a UEFI variable that is specific to each main operating system on a client. These OS-specific UEFI variables can be employed to identify which main operating system has failed to boot. When a main operating system fails to boot, a UEFI preboot application can be configured to access the UEFI variables to identify which main operating system has failed. The UEFI preboot application can also obtain characteristics of the failed operating system from the UEFI variable and include such characteristics in a vendor extension of an SLP request. A server can employ the characteristics defined in the vendor extension to identify and send an appropriate service operating system to the client.

  • Publication number: 20200250314
    Abstract: UEFI images can be securely loaded at runtime so that it is unnecessary to flash the entire platform firmware whenever a UEFI image is added or updated. The platform firmware can include an OEM file list that maps file GUIDs to public keys. When it is desired to add a UEFI image, the OEM can employ one of the file GUIDs in the OEM file list and a private key corresponding to the mapped public key to create the UEFI image. During the PEI phase of the boot process, a verification module in the platform firmware can verify any added UEFI image using the OEM file list. Additionally, to ensure that the added UEFI images will pass the subsequent Secure Boot verification, a sync module can add custom Secure Boot keys for the added UEFI images to the Secure Boot databases during the DXE phase of the boot process.
