You should choose the type of processor u have. SMP is for 2 processors i686 for p4 and newer amds and i386 for pentiums and equivalents.

basically i386 means that the code shall run on all Intel CPUs starting from 80386 DX and also AMD CPUs.

However,compiled code can be optimized for a certain target architecture.

i686 means optimized for Intel Pentium II (PII including PIII based Celerons and Xeons) and above.

K7 means optimized for AMD Athlon/Duron.

SMP means Symmetric Multiprocessing and you shall use this kernel *only and only* if
you have 2 or more CPUs in your machine.

If you have only a *single* CPU then do *not* use SMP kernels.

Although the compiler optimization for a certain CPU type perform optimization,
the performance benefit, if at all, is not that high.

When in doubt: use always i386. This will work and in most cases there isn't that much
performance difference between i386 and optimized code.
