Razer firmware archive referencing the Blade project codename spelled beffy, R6 motherboard, fcs v4, with dumps for chip positions U43, U44 and U49, in a 296 KB RAR. The small size suggests EC or other small flash contents rather than a full BIOS, so check each file against its target chip. Each U number refers to a component reference on the board, which a boardview can help locate. Program chips with a suitable programmer, backing up the originals first and confirming image sizes match chip capacities.
The button opens the matching file on RM Schematics, or a source page if it is not catalogued there yet. The original attachment is from @biosarchive. Enginerys does not host this file.
