BIOS dump labelled M3500QA for board revision 2.1, a 16 MB image compressed in a ZIP of about 15 MB. The name gives no brand, so check that the model and the 2.1 revision printed on your board match before writing it. A 16 MB file is intended for a 128 Mbit SPI flash chip, typically reprogrammed with a CH341A, RT809 or similar tool after reading the original. Keep a backup of the existing contents, because serials and system identifiers stored in the flash can be lost when a foreign dump is written.
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.
