Firmware archive with a very uninformative name, z6000, giving no brand, board number or chip details; it is an 11.6 MB RAR filed as BIOS or firmware. Before use, extract it and inspect the contents to work out what device and flash chip the image is intended for, for example by checking embedded strings with a hex editor. Only program it when the image size equals the target chip capacity, and always read and save the existing chip contents with an SPI programmer first so the original can be restored.
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.
