Dear Bob, The question is not stupid. However, I have searched the webpage before I install SL and found that AMD Sempron 2600+ is a 64bit CPU.... I think AMD Sempron 2600 (without +) is a 32bit CPU indeed. I don't really know the names of these CPU, actually. The story is that I have a fixed amount of money and I ask the company to give me the best CPU I can buy so they decide that SPN2600+ with 512MB ram is the best I can buy. Then I started to figure out what version of SL I should install... I do not know whether this "64bit" in the webpage only means that it can work with 64bit address space like xeon EM64T.... Thanks a lot and I look forward to your further input.
