Working BIOS for an Acer laptop on the Rayleigh_SLS mainboard, Wistron number 14302-1M, delivered as a 6.77 MB rar and labeled fully working. Wistron, an ODM for Acer, uses five-digit project numbers with a dash suffix like this on its PCBs. The dump serves to recover a board with corrupted firmware by reprogramming the SPI chip with an external programmer. Check that the PCB shows Rayleigh_SLS 14302-1M, save the original chip contents first, and ensure the image size matches the chip.
