Look up your motherboard here. It would help if you looked at
the motherboard itself, and read the "Rev" number in white text,
next to the motherboard name. There are several different
versions of board, like 1.04, 1.06, 2.0 and so on.

As for your upgrade, remember that the P.R. rating of an AthlonXP,
compares to a P4. Thus your current processor is the equivalent
of a P4 2.2GHz. The Sempron P.R. ratings are compared against
a Celeron, a weaker processor. A Sempron 3200+ compares to a
Celeron 3.2GHz, so you have to derate the number a few hundred
MHz to get a rating to compare to your 2200+.

I don't know if there are any issues with that version of board,
but I would research whether a AthlonXP-M can work in that board.
The forums on nforcershq.com might have some info. XP-M can be
a bit cheaper than looking for a Barton, but work every bit
as well. For example, the 2500+ or the 2600+ can be overclocked
to perform at a Barton 3200+ level, for $85 and $97 USD respectively.
Read the "Review(s)" link next to each item, to see feedback from
customers on how well it worked:

I use a 2600+ XP-M on a A7N8X-E and it runs 200x11 = 2200MHz or
barton 3200+ equivalent, at 1.65 volts. I use DDR400 CAS2 memory.

More info on overclocking can be found here.
Select "Athlon XP-Mobile 2500" or "Athlon XP-Mobile 2600"
to see how many processors made it to 200x11.

Also, your current processor is FSB266. There are a couple of
2200+ models, and this is an example spec of one. Your RAM speed
might be an issue, so think about how your RAM speed limits
meet up with any potential upgrade. If you had DDR400 RAM,
the upgrade situation is much clearer, than if you had, say,
DDR266 (PC2100) memory. A faster memory can be run at a slower
speed, but the vice versa means overclocking the memory, which
would be a lot tougher with that chipset.

1800 (2200+) OPGA 133 256   13.5x 1.60V 85oC 57.0W

133Mhz CPU clock = FSB266, matches 1:1 with DDR266 memory rate.
166Mhz CPU clock = FSB333, matches 1:1 with DDR333 memory rate.
200MHz CPU clock = FSB400, matches 1:1 with DDR400 memory rate.
