What is the difference between the "A" and the non-A versions?

I thing the "A" version has the KT133A chipset. But what's the difference btwn that the the non-A version? Thanks.

You're right, the 'a' version has the KT133a chipset, and the normal version has the KT133 chipset. The major difference is that the KT133a allows a fsb of 133MHz (and then some if you oc it, I've heard of some early KT133a boards doing 155+). The KT133 only allowed a 100MHz fsb, and this could only be raised to about 110 before system instability set in. This basically means greater bandwith and better performance in the KT133a boards, as data can be transferred between the cpu and northbridge at a higher rate.

KT133a also features the 686b southbridge, which has native UDMA 100 support - KT133 only had UDMA 66 support, so you needed an extra ATA100 contoller on the board.
