The first thing I'd do is update to the latest BIOS. Even that may
not be enough, the board may not POST at all, at any speed. That is
what I'd expect to happen, no post. There's a better chance it
would've worked with an XP1600 Palomino, but then that's not near as
much of an upgrade. Maybe it'll work though, but the 100MHz FSB and
PC100 memory will cripple performance.
The KT133 chipset was "originally" meant to support 133MHz (DDR266)
FSB but it never quite made it, none of those boards are stable much
over 100MHz (DDR200). You might find it's stable up to around 110MHz,
but that's about all you'll get. IF the board manages to post you
should go ahead and choose the higher multiplier it offers, but I
expect you'll have instability because a board that old isn't designed
to support the power requirements of the processor, it was doing good
to even work with the Duron 1.3GHz.
IMHO, you shouldn't even try the CPU in that board, as slightly more
modern boards, new enough to support an XP2500 are pretty cheap these
days, and give MUCH more performance per CPU MHz. Basic PC2100 memory
is pretty cheap these days too, though I hear the price is still
rising slowly.
