BIOS archive for a device or board identified only as A961P, marked as tested, so it is reported to have worked on real hardware. The 6.24 MB RAR gives no brand or chipset in its name, so match the identifier against the label on your board before use. Firmware dumps like this are written to the SPI flash chip with a programmer such as a CH341A when a corrupted BIOS causes no boot. Compare the image size with the chip capacity, and read and save the original contents before programming.
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 @hrtechno. Enginerys does not host this file.
