KT133A chipset barely supports first Athlon XPs(Palomino and T-Bred), it might take a Barton, but it would be safe to test that cpu somewhere else before saying it's bad
Well I said it seems to be defective, couse of these reasons:
1) every revision of KT7A (even V 1.0) can at least POST with a barton:
http://www.motherboardpoint.com/kt7a-raid-barton-xp-2500-333-works-ok-t437.html(note that this is not the only guy on the net with successful barton experience
There are many, many others according to google)
2) mobile barton and a normal one are 1:1 the same architecture and pin-to-pin compatible. Mobile ones are just cherry picked ones that work on lower voltage:
http://en.wikipedia.org/wiki/Athlon#Barton_and_Thorton Quote:Mobile Athlon XPs (Athlon XP-M) are identical to normal Athlon XPs, apart from running at lower voltages, often lower bus speeds, and not being multiplier-locked.
Therefore, CPU must have been defective.
