Raw 4 MB binary dump labelled Tokyosat TS 3221, most likely firmware for a satellite receiver of that brand. The name gives no board number, revision or chip type. A 4.00 MB size corresponds to a 32 Mbit SPI flash, so the chip being written should have that capacity. Technicians write such images with a programmer such as a CH341A or RT809H to recover a unit stuck on boot. Read the original chip contents first and confirm that the hardware version matches before writing.
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 @hashmielecom. Enginerys does not host this 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 →
