is a specialized firmware utility designed to update and manage BIOS/firmware on Chromebooks specifically when they are running the Windows operating system. Developed primarily by CoolStar , it serves as a bridge for users who have converted their ChromeOS devices into "Chrultrabooks" (Chromebooks running Windows) and need to maintain or update their system firmware without reverting to ChromeOS or Linux. Core Functionality

: Newer versions include support for nvram firmwares and specific hardware platforms like Braswell chromebooks.

: Extracting and migrating critical hardware variables (like serial numbers and MAC addresses) from the older firmware region to the newly flashed image so hardware functionality remained stable.

: Designed for Intel-based Chromebooks/boxes that are already running custom UEFI firmware. Important Considerations
