	In no way do I blame anyone for ordering the big RAM chips. I 
got the opinion from several emails that you should have 4 GB 
of RAM before using 64bit. This I have said is not the case 
since the 64bit computer I write this on is running fine with 
2 GB of RAM. I have lots of money so the issue is not important.
