16 MB image for a Winbond W25Q128BV flash, labelled as option 1, which suggests one of several alternative dumps for the same machine. The name does not state the device or board, so identify the source from the BIOS strings in the file. When several versions exist, try one at a time and keep the original backup safe. Write it with an SPI programmer only to a 128 Mbit chip. Confirm the board matches the source machine to avoid a non-booting unit.
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 @biosfilebins. Enginerys does not host this file.
