Systems and methods for injecting an overlay into a video framebuffer memory by a Basic Input / Output System (BIOS) without triggering a host Operating System (OS) error. An Information Handling System (IHS) includes a processor and a memory coupled to the processor. The memory stores program instructions that, upon execution, cause the processor to receive a command from an Embedded Controller (EC) and create an Advanced Configuration and Power Interface (ACPI) table with a video framebuffer memory location usable to store an overlay. The EC issues the command in response to the IHS returning from a selected power state or determining that the IHS is in a selected posture. The overlay may include a software keyboard icon or an Original Equipment Manufacturer (OEM) splash screen. The host OS checks the ACPI table during boot and allows the BIOS to write to the video framebuffer memory location without triggering an error.

Systems and methods for cross operating environment diagnostic operations with context resume. An Information Handling System (IHS) includes a processor and a memory coupled to the processor. The memory stores program instructions that, upon execution, cause the IHS to receive a command at a Basic Input / Output System (BIOS) from an Embedded Controller (EC) to perform a deep scan diagnostic operation. The command is received in response to a request by a host Operating System (OS) application. The BIOS executes the deep scan diagnostic operation and stores the result in an Advanced Configuration and Power Interface (ACPI) table. The host OS retrieves the result from the ACPI table and validates the result. The system enables comprehensive diagnostics by leveraging the BIOS environment, ensuring seamless context resume.

The embodiment of the invention discloses an ACPI table updating method and related equipment, the method and the equipment are used for computer equipment, the computer equipment comprises a first storage space and a second storage space, and table structure information of each sub-table in an ACPI table and corresponding first content are stored in the first storage space. The method comprises the following steps: firstly, writing table structure information of each sub-table in M sub-tables and corresponding second content into a second storage space; when a creation instruction for the ACPI table is received, the first table structure information can be queried in the second storage space based on the creation instruction. If the query succeeds, the BIOS creates a first sub-table based on the first table structure information in the second storage space and the corresponding second content; and if the query fails, creating a first sub-table based on the first table structure information in the first storage space and the corresponding first content. Therefore, a developer does not need to flash the BIOS file and only needs to update the content of the sub-table in the second storage space, so that the efficiency is improved, and the computing power consumption is reduced.
