Pentium 3 cache latency: odd results

[Eva_Unit_0]

So I've been playing around on my dual P3 box and I decided to run cpu-z's cache latency tool, and it gives some interesting results. These are coppermines with 32kb L1 and 256kb full-speed L2. It reports those two cache sizes correctly, but it also reports a 128kb cache in between the two. Also, the latencies seem odd...it says the latency to the 256kb cache is 20 clocks which is far too long for P6 (my mobile P2, which is essentially the same core just without sse and a larger process size, gets 11 clocks to the L2) Does anyone know what's going on here? Why is it reporting 3 cache levels...is it something strange with SMP that I've never seen before?
