UEFI firmware file with the .fd extension, 2 MB, labelled PEW52113, apparently build 113 of the same BIOS line as the PEW52114 release. No model or board number is given, so identify the target by comparing the PEW prefix with the BIOS version shown in setup or printed on the flash label. Images of this kind can be opened in UEFITool to check their structure. Some may need a capsule header stripped before an SPI programmer writes them to the chip. Back up the original first.
