BIOS firmware package for the ASRock Z77 Extreme3 desktop motherboard, version 1.50, supplied as a 4.66 MB zip archive. The Z77 chipset places the board on the Intel LGA1155 platform. Technicians use such an image to recover a board that fails to post after a corrupted update, either through the vendor flashing utility or by writing the SPI chip directly with a programmer. Read and save the original chip contents first, and confirm the image size matches the flash capacity before writing it.
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.
