I would love to try your modded bios. I will send you a PM. I will post the exact model of the motherboard Monday when back at work. I did backup my current bios and used the tools you mentioned in your post, but with my inexperience with bios modding, I did not make any changes yet.
Long time lurker and first post.
I purchased an 1155 Inventec server board for $16 eBay link
Once I received the board, powered on and I can login to the BMC.
While waiting for my E3-1270, I popped in a Pentium G2030 Ivy that supports ECC and it boots!
