ECS P67h2-a3 v1.0 need full 4MB bios rom

[zorobabel]

Hello bios modders, 

I'm trying to find a 4MB bios rom for the ECS P67h2-a3 v1.0 motherboard. The rom on the ECS website is only 2.5 MB and doesn't work by itself.

The story: I stupidly tried to flash from within W10 x64, the result was no post.
Reading through various online sources, I succeeded in making a cable for the SPI header and using SPIPGM I made a bios backup. Unfortunately I didn't verify it, so I don't know if it's good or not. I erased the chip and copied the 2.5 MB rom to it, but this results in power on/off forever. With the failed bios upgrade at least the power/fans stayed on.

Hopefully someone has this (rare) board, and is willing to make a backup of the rom, please!

Thanks
