Firmware archive for the P8Z77-V DELUXE desktop motherboard, packaged as a 4.17 MB RAR with no version number given in the name. The larger size suggests a full dump or several files, so inspect the contents after extraction before choosing what to write. A technician would use it to reprogram the BIOS chip when the board is dead or stuck in a boot loop. Match the PCB model marking carefully, save a copy of the original chip with a programmer, and confirm the image size equals the flash capacity.
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 @afsbiosfree. Enginerys does not host this file.
