compiling kernel

[Lazar Fleysher <fleysher@chudo.lanl.gov>]

Hi everyone!

I am trying to compile 2.217 kernel and I am offered to choose the CPU
family. Could someone, however, explain the difference between 
-- "586" for generic Pentium CPUs, possibly lacking the TSC 
and 
-- "Pentium" for the Intel Pentium/Pentium MMX, AMD K5, K6 and K6-3D

and how to check if my CPU supports TSC?

Thank you,

Lazar
