uname -a will do it - will tell you if you're running a 32 or 64 bit kernel.
To check the processor's ability (regardless of the kernel being run), grep "lm" /proc/cpuinfo. If your cpu has the "lm" flag (long mode), it's 64-bit. You should download the IDE that matches your kernel. When in doubt, you may be able to run the 32 bit version on a 64 bit system without problems. On Wed, Sep 22, 2010 at 1:46 AM, "J.
