Zip archive of 2.29 MB for the P8H61-M LX3, an ASUS micro ATX desktop board based on the Intel H61 chipset as the model naming indicates. The contents are not described, but a package of this size usually holds a BIOS image for the board's SPI flash. It can be used to recover a board that fails to POST after a bad update. Read and keep the original chip contents with a programmer before writing, and confirm the exact model variant on the PCB, as several P8H61-M versions exist.
