@pojo: Thank you very much for your solution!
I just had the same exact problem with an ABIT BH6 board. I got the same exact error message and everything when using AWDFLASH version 8.99.
Like you, I also read through the entire manual looking for the solution to find no answers at all.
I just downloaded and used the older AWDFLASH version 8.23 and everything went as smooth as butter!
The funny thing is that this 1 post was the only result that came up on a Google search out of the entire internet. Now if anyone in the future has this problem with an ABIT BH6 board, they will know that this solution will work for that board as well. 😀
