@dg1972 :
Attached are 2 different AMD AHCI drivers, which have been customized by me to make them usable with your on-board AMD AHCI Controller and Windows XP, but I cannot give you any guarantee, that any of them really will work for you.
Please try them both and report, whether they work or not.
