[newbie] Rpm designations

[Myers, Dennis R NWO]

Title: Rpm designations

Can somebody explain the difference in .i386 and .i586 designation in rpms    Sometimes you have a choice and I'm not sure but I think that this is referring to processor class. I have a AMD K-6 II 400 and I think the .i586 is ok for that processor?  Somebody educate me here.  Thanks, Dennis
