Abstract: Certain aspects of the disclosure relates to a system and method of performing virtual media redirection. The system includes a baseboard management controller (BMC) connected to a host computing device through a communication interface, and a client computing device communicatively connected to the BMC through a network. In operation, the BMC emulates a virtual media for a media device, and establishes a virtual media connection to the client computing device through the network. Then the BMC stores the data from the media device in a host cache at the BMC and in a client cache at the client computing device by sectors. When the BMC receives a request from the host computing device through the communication interface to retrieve sectors from the media device, the BMC redirects the sectors being requested to the host computing device depending on where the requested sectors are stored.

Abstract: Technologies are provided for multi-redundant digital signage. A video server computer connected to one or more digital displays is configured to receive one or more videos and content, such as an image or a video, from a content server. A video player application executes on the video server computer to display the video received from the content server on the digital displays. An operating system executing on the video server computer is also configured to present the content as a desktop background. If execution of the video player application fails, the desktop background is presented, thereby displaying the content received from the content server. Additionally, the content may be stored in a non-volatile memory of the one or more digital displays. If a video signal from the video server computer is lost, the digital displays may present the content automatically or in response to a manual user input.

Abstract: Technologies are provided herein for automated operating system installation on multiple drives. A device switch connects a mass storage device to a test control system (“TCS”) or a system under test (“SUT”). When connected to the TCS, the mass storage device is mounted with a disk image containing an installer program for an operating system. When the mass storage device is connected to the SUT, the installer program is executed to install the operating system onto an activated drive connected to the SUT. Multiple operating systems can be installed in a similar fashion by mounting a corresponding disk image for an operating system onto the mass storage device and by installing from the mass storage device the operating system onto a corresponding drive connected to the SUT. Errors generated during the automated installation process can be analyzed and utilized to identify and correct errors in a computing system firmware.

Abstract: In one aspect, a system includes a service processor (SP), having a processor, a non-volatile memory and a communication interface. The SP receives a component information of components of a host computer from a basic input/output system (BIOS) being executed at a central processing unit (CPU) of the host computer through the communication interface, and stores the received component information in the non-volatile memory. When the SP receives an instruction to display a physical layout of the components of the host computer, the SP retrieves the component information for each of the components stored in the non-volatile memory, and generates corresponding display information for each of the components based on the retrieved component information. Then the SP may send the display information to a remote management computer to display a graphical diagram of the physical layout on a display device at the remote management computer.

Abstract: Aspects of the disclosure relate to systems and methods of recording video frames from a computing device by a management device. The management device may receive video frames from the computing device. In response to receiving the video frames, the management device may process the video frames in a first-in-first out (FIFO) order to generate processed video frames according to a recording method, store the processed video frames in the FIFO order in the memory of the management device, and then release the memory occupied by some of the processed video frames in the FIFO order based on a memory releasing condition defined by the recording method to store the processed video frame. The memory releasing condition is determined by multiple optimized parameters of the recording method. The recording method may be a sliding window recording method, a multiple-window fixed size recording method, or a multiple-window dynamic size recording method.

Abstract: A computing system firmware is provided that includes functionality for securely authenticating a user of the computing system prior to allowing the user, through an application running on an operating system, to invoke firmware functions and to access and modify firmware variables. The authentication may use the same authentication credentials used to access firmware utilities during the computing system's power-on self-test (POST) phase. Upon receiving requests to access firmware assets, an authentication service determines whether the access has been authenticated for the user. If so, access to the firmware assets is granted. If access has not been authenticated for the user, the authentication service attempts to authenticate the user by verifying the authentication credentials passed along with the request.

Abstract: A computer system firmware is provided that includes functionality for allowing a calling application to invoke firmware functions through the use of firmware services for getting and setting firmware variables. Firmware functions may be defined and mapped to firmware variable names. When a request is received by the firmware to get or set a value for a particular firmware variable, the firmware determines whether a custom firmware function has been defined that corresponds to the requested firmware variable. If a custom function has been defined that corresponds to the requested firmware variable, then the corresponding custom function is executed rather than the requested get or set operation. A firmware setup application might utilize this mechanism to obtain information from a firmware for use in modifying the configuration of a computer system that would not otherwise be available to the setup application.

In operation, the IoT tap device requests and receives the temperature signal from the temperature sensor, and determines the environmental temperature based on the temperature signal. When the environmental temperature is at or below a threshold temperature, such as a freezing point of water, the IoT tap device controls its tap to switch to the open state such that water flows or drips out from the tap.

Abstract: In one aspect, a system includes a service processor (SP), having a processor, a non-volatile memory and a communication interface. The SP receives a component information of components of a host computer from a basic input/output system (BIOS) being executed at a central processing unit (CPU) of the host computer through the communication interface, and stores the received component information in the non-volatile memory.

Once the component information is updated, the SP may, in response to receiving the component information from the BIOS, send the updated component information back to the host computer through the communication interface.
