There are different versions of each Athlon chip. There are different
desktop versions (XP) and mobile versions (XP-M) .

- XP 2400+ Thoroughbred-B and Thorton cores, both 266FSB.
- XP 2500+ Barton core, 333FSB.
- XP 2600+ The (rare) 266FSB version has a Thoroughbred-B core. The
readily-available 333FSB versions come in Thoroughbred-B and Barton cores.

- XP-M 2400+
- XP-M 2500+
- XP-M 2600+ All are unlocked and 266FSB as standard, and usually default
to a low multiplier on desktops. If your BIOS doesn't have incremental
multiplier, FSB and voltage settings, you could be stuck with a very slow
CPU.

The SV266A probably doesn't have incremental settings, so an XP-M may be out
of the question. The 333FSB XPs won't be able to run anywhere close to
their abilities on a 266FSB motherboard. The 266FSB XP 2600+ is difficult
to find, so an XP 2400+ is the best option.
