Firmware archive for a Pegatron-built Turbox A15YA board at revision 2.1, tagged Q2542 and labelled for Windows 8. The ZIP most likely holds a BIOS image for reprogramming the SPI flash with an external programmer after a failed update or corruption. Pegatron is an ODM that produces boards for several brands, so check the model and revision printed on the PCB against A15YA rev 2.1. Back up the original chip contents before writing, and confirm the image size equals the chip capacity.
