The image extracted from the updater contains not only the firmware image but also configuration files and executables.
The files that we just copied need to be extracted before we can use them to flash. At this point the updater program can be closed which will result in the temporary directory being deleted. They usually have an extension of '.fd', '.bin', or '.rom' and should have a similar size to the ROM on the actual board. In the temporary directory locate the image files and copy them to another location. With some versions of Insyde Flasher executables it is possible to open the program directly with something like 7-Zip and extract the files without going through the trouble of running the program. Extracting the ExecutableĮxecutable updaters for Insyde firmware are best extracted by opening the updater, ignoring the error that will pop up on an unsupported machine, keeping the error message open, and locating the folder that is decompressed into the temporary file directory (%TEMP%) which typically starts with the prefix '7z'. Most Acer firmware updates are delivered in the form of the Insyde Flash Firmware Tool. Executable updates for Insyde firmware are easily identified by the application icon and commonly used across many different brands of computers.
