Firmware archive labelled G41MXE rev 1.2, presumably a desktop motherboard based on the Intel G41 chipset, though the board maker is not named. The small 521 KB RAR likely holds a BIOS image for the board's SPI or LPC flash chip. Use it to recover a board that will not POST after a failed update, writing it with a programmer. Check the model and the 1.2 revision on the PCB, read the original chip first, and make sure the image size equals the chip capacity.
