I was always under the assumption that all Socket A Athlons were either T-Birds or Durons. Today I was thrown a curve ball. A neighbor has a Gateway 1100 system. It is a 1.1 gig Athlon Socket A processor on a MSI (Gateway special) motherboard using the KT133 (not Apollo) chipset. They had installed an internal IDE Zip 100 meg drive and it wasn't working so they ask if I would look at it. Well the installation seemed fine but it just wasn't being found. Then I remembered that certain VIA chipsets and 100 meg internal zip's don't get along. So going on the internet to Gateways site I was able to determine some info, but we called Gateway for some more information. According to the support person the processor is a 1.1 Gig Socket A Zif processor not a T-Bird. So I learned something new today - Not only are there Classic Slot A Athlons, but there are "classic" Socket A Athlons (I did not know that!).
Oh downloaded the new VIA 4 in 1 driver and all was well with the zip drive.
