BIOS image tagged Z30 A3667A MDK MB-17W 1402-2 for an 8MB flash chip, provided as a 3.29 MB RAR archive. The name gives no clear brand or model, only these board and project markings, so identify the device by comparing them with the text printed on the PCB. Such a dump is written to the SPI chip with a programmer to recover a board with damaged firmware. Always read and save the original chip first and confirm the extracted image is exactly 8 MB before flashing.
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.
