BIOS archive labelled Q1X0MS with a 16 MB image size, and no brand or model in the name. Another file links a similar code, 1Q1X0MS, to the Lenovo ThinkStation P310, but confirm that against your hardware. The 8.87 MB RAR should extract to a 16 MB image for a 128 Mbit SPI chip, and an image of a different size will not fit. Read the original chip with a programmer and keep the backup before writing, so unique system data 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.
