Full SPI flash image for the Star X 99 Laser receiver, read from a Winbond W25Q64 chip. At 8 MB it matches the 64 Mbit part exactly and should be written as a whole-chip image, not loaded as a USB upgrade file. The mk suffix in the name is unexplained. Typical use is reviving a unit frozen on its logo or looping at power-up. Dump and keep the existing chip contents before erasing, and check that your board really carries a 64 Mbit memory, because a smaller chip cannot hold it.
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 @tamirkaran_chanel. 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 →
