Re: How do I determine if the hardware of redhat server is 64 or 32 bit

x86info might get you what you need.

Or looking through dmesg or /proc/cpuinfo. 

You should be able to at least cross-reference the CPU model detected with the list on intels/amds site.

I had a 64 bit box running a 32 bit OS, but I recently upgraded, so I can't check for you.
