If you want to know if it is a 64 bit or 32 bit cpu you can check cat /proc/cpuinfo and look for the flag lm (not lahf_lm that is something completely different)

 $ cat /proc/cpuinfo | grep lm


* FW4L    - CPU : 2nd Generation Intel® Atom Dual Core D525

Support for 64-bit OS and 4GB
Please note though that as no 64-bit video drivers are available, 64-bit installations will use generic drivers meaning limited screen resolutions and no video acceleration.



* Mini PC - CPU : 3rd Generation Intel® Atom Dual Core D2550

Support for 64-bit OS and 8GB Memory: Intel Atom operates in 32-bit mode only and officially only supports 4GB. Intel's support for this chipset is limited to 32-bit Windows (which can only address 3.5GB memory). However the board will address 8GB of memory (as 2x 4GB DDR3 SODIMMs), and 64-bit support is enabled in the BIOS. Please note though that as no 64-bit video drivers are available, 64-bit installations will use generic drivers meaning limited screen resolutions and no video acceleration.
