Hmm. That is an interesting though. The machine I am looking at I know has a 64bit processor, but I installed the 32bit kernel, and finding something that sticks out is proving to be difficult. Here are the results of what most sites suggest: [EMAIL PROTECTED] ~]# uname -m i686 [EMAIL PROTECTED] ~]# getconf LONG_BIT 32 Both of these would indicate I have a 32bit processor, but this is only what the kernel is reporting, not what is truly there. As far as /proc/cpuinfo, the only 64 listed is in the clflush size. Maybe this is a good indicator. The AMD processors are so much easier as they all say "Athlon 64" in the model name. Intel is not quite so nice in this regard.
