Probably the only thing new is support for Model 10 Athlon XP CPU's i.e. the Barton line of CPU's
Here's what's taken from the .inf file:
%AmdK7.DeviceDesc% = AmdK7_Inst,ACPI\AuthenticAMD_-_x86_Family_6_Model_10
Any folks using older Athlon XP models viz Palomino, Tbred, etc and are saying they have experienced better stability, performance etc are only getting the "Placebo Effect" 🙂
