I'm thinking of using a Linux payload before, but I failed to use an 8MB flash (W25Q64FVAIG) on ASRock H81M-HDS with all flash space used.
I can only use the first 4MB with the original IFD, and the board doesn't boot after I change the IFD to use the whole 8MB flash.

I don't know, but as a test, I'd be very interested to see what
happens with a linux payload. You probably don't have time for such a
thing but I had to ask :-)
