Thank you! Just saved my bacon with a new X10SRH-CF that came with bios v.1.0a from early 2014! WTH, this machine was just decommissioned, unreal the bios was NEVER updated! I had already installed a E5 v4 CPU on the board and the latest bios v.3.4 would not update via IPMI. Unable to find older v2.x of this bios, using your link, I found v2.0b and the update was successful with a v4 cpu on the board. According to Supermicro, any bios below v2.0 requires a v3 CPU to get up to v2.0 or above. Figured I'd go ahead and give it a shot as that was quicker than swapping in a v3 CPU. Success! Now went from v2.0b to v3.4 which is the latest and all is good! Thanks again!
