BIOS file for the ECS RS740M-M desktop motherboard, packed as a 598 KB RAR. The model name refers to the AMD RS740 chipset that the board is built around, and the small archive fits the compact flash chips of that generation. It is used to recover a board left dead by a failed update, either by programming the chip out of circuit or with an in-circuit clip. Check the exact board model and PCB revision, and back up the existing chip before writing the image.
