BIOS firmware for an Acer system built on a Foxconn motherboard identified as RS690M03-8EKRF-S2H, provided as a 386 KB RAR archive. The RS690 part of the name points to an AMD 690-series chipset platform from the Foxconn board code. The small size suits older parallel or SPI flash chips of limited capacity. Use it to recover a board with corrupted firmware via a programmer, after dumping and saving the current chip contents and confirming the image size matches the chip fitted.
