BIOS image package for the ECS H61H2-M6 motherboard, revision 2.0 according to the name, packed as a 2.87 MB RAR. This Intel H61 board appeared in OEM desktops, so dumps of it circulate under several labels. The file is intended for reprogramming the SPI flash chip with an external programmer when the board fails to post due to damaged firmware. Confirm that the PCB is marked version 2.0, as earlier revisions may differ, and read a backup of the original chip before you write.
