With this portable kit, you can walk up to any dead H61H2-MV system and revive it in 5 minutes. If you frequently work on ECS H61 chipsets,
Some H61H2-MV boards have ECS’s "M.I.B. III" (Motherboard Intelligent BIOS) inside the BIOS itself. You can place the .ROM file on a USB drive, enter BIOS, and choose "EZ Flash" or "BIOS Update".
