a problem with the datasheets. The SB600 datasheet from AMD documents informs nothing about the PCI registers pertaining to "flash enable".
Since AMD has released detailed datasheets for a few ATI graphics cards in the last few days, I expect detailed SB600 datasheets may be on the horizon as well if we ask nicely.
@AMD: Is there any information missing from the public SB600 data sheets?
However, it is quite possible that SB600 has no flash enable and this is entirely managed by GPIOs on the SuperIO.
I see.
The only solution is to reverse-engineer a working solution, i.e. Award
Winflash to find out about it because it supports the platform. I need this because I need to test my further Winflashrom code in my testbed prior to releasing it. Unless someone would donate a motherboard with an already supported chipset ;-).
My question is, how can I provide you guys with a clean source code that would be legal?
I have quite some experience with clean room reverse engineering. Back then, it was the Nvidia network driver where we (Andrew de Quincey and me) wrote a hardware data sheet from the binary driver and someone else implemented forcedeth just by looking at the data sheet we had written.
Should I be producing a document and someone else here code it for me
and
others?
Generally, if you intend to work on the code later on or work on winflashrom at all, you should make sure somebody else does the reversing and writes the data sheet. That way, you are free to implement a clean solution from the data sheet.
I see. So, I should wait for someone else who would like to do that for the rest of us here because actually I am more to writing code for winflashrom than the reverse engineering. ( even if I'd love to reverse it myself :-) -> we should stick to the rules )
( I think this is what "clean room reverse engineering", right?)
Yes, but the recommendations above apply.
Thank you very much for the insight ;-)
