Raw binary BIOS or firmware dump with an uninformative name, ZQS, that identifies no brand, model or board number. The file is exactly 4.00 MB, which matches a 32 Mbit SPI flash chip. Such dumps are written to the chip with a programmer such as a CH341A or RT809 when recovering a board. Without a clear origin, open it in a hex editor or a firmware tool to look for vendor strings and the board ID before use. Always read and save the original chip contents first, and make sure the chip capacity matches.
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 @bioshub. Enginerys does not host this file.
How to open a .bin file
A raw, byte-for-byte image of a flash chip: the main BIOS / UEFI, the embedded-controller (EC) firmware, or both.
Back up your own chip before writing any dump, and match the full board number and revision. Flashing guide →
