Firmware capsule in .fd format, 2 MB, named PEW52114, which looks like a BIOS version string ending in build 114. The .fd extension is commonly used for UEFI firmware volumes distributed by vendors, and these are often flashed with the maker's update tools. They can also be inspected with UEFITool before being written to a chip. The name does not state the device model, so match the version prefix to your machine's current BIOS ID. A sibling file from build 113 exists, which is useful when rolling back.
