ASUS P8H61-M LE R2.0 desktop motherboard BIOS archive, firmware version 1408, in RAR format. The board is built on the Intel H61 chipset for LGA1155 processors. ASUS distributes such updates as CAP files which include a capsule header, and a raw SPI image may need that header removed before programming with an external tool. Read and keep a copy of the original chip contents, and confirm the board is the R2.0 variant before flashing.
