Firmware dump for the Biostar TB85 motherboard, version 6.0, marked as tested and working, although the catalogue lists ECS as the brand. Version 6.0 may refer to the board revision. The RAR archive is 5.01 MB and is intended for restoring the SPI BIOS chip with an external programmer when the board will not post. Confirm the model and revision printed on the PCB, read and save the existing chip contents, and verify that 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 @biosarchive. Enginerys does not host this file.
