Default Optimizing for CPU architecture: unknown Intel

I just installed Prime95 on my new Gateway netbook. It has an Intel Atom N2600 processor, which is supposed to be dual core hyperthreaded with L2 cache size of 1MB. Prime95 tells me "unknown Intel L2 cache size 512K, Logical CPUs 1,2 form one physical CPU, Logical CPUs 3,4 form one physical CPU." Why does Prime95 not recognize my Atom N2600 processor? Do I need to tell Prime95 that my L2 cache size is 1MB? Thanks.

I don't think prime95 will select a different FFT implementation with the correct L2 cache size info, but it won't hurt to set CPUL2CacheSize in local.txt (see undoc.txt).

I don't expect great performance on an Atom processor.
