Duplicate of a compressed firmware package for the Envy 4 line, labelled ok to indicate a working dump, 3.39 MB as a .rar archive. Neither the board revision nor the exact chip type is mentioned, so inspect the archive contents after unpacking with 7-Zip or WinRAR. Such packages are used to restore BIOS or EC chips on boards that no longer start. Make sure the extracted image size matches the flash capacity and the PCB number matches before writing, and save the original data first.
