Tested on: Supermicro H8SCM-F-O, AMD SP5100 Please note, that I did no proper code review, I only tested, so let me know if the "acked-by" sign-off should not be used here.

I have marked the chipset as tested and will commit that later together with other small changes. There are two revisions of your board: 1.0: http://www.gigabyte.com/fileupload/product/2/3854/4279_big.jpg and 1.3: http://www.gigabyte.com/fileupload/product/2/3974/4929_big.jpg They look almost identical and are probably indistinguishable from each other for flashrom, but for the record I'd like to know which one you got? -- Kind regards/Mit freundlichen Grüßen, Stefan Tauner
