Tested working BIOS for Quanta board DA0P5HMB8F1, revision F, as stated in the name. No laptop brand or model is given, so match it by the board number printed on the PCB. The 6.45 MB RAR should hold a flash image for reprogramming the BIOS chip with an SPI programmer after corruption. DA0...MB numbering is used by Quanta, which builds boards for several brands. Save the original chip contents first and confirm the image size matches the flash chip before writing.
