Any reason I can't use that? Soyo's website seems to indicate that I can't use anything newer than a Palomino core, and the 2800+ is a Barton core. Is it simply that Soyo decided not to produce the necessary BIOS update for my old motherboard?
No, the 2800+ is not 266, but 333. There is a rare T-Bred version of the 2800+ as well as a Barton version, both of which are 333 FSB parts, but that doesn't matter. It's not the the FSB, it's the core.
There are many Soyos which can ONLY run Palominos.
There is nothing you can do, there is no BIOS update, it's a board problem, it cannot run T-Breds or Bartons...
I've experimented a lot with this and managed to get one of these Palomino-only Soyo boards to appear to start working with T-Breds but sure enough, the system ended up terribly unstable.
