I'd like to upgrade my FreeNAS 8.2.0 (BSD based) and wanted to double check which disk image (32 bit or 64 bit) to download – I'm 90% sure that my hardware (dual core Atom board bought about 2.5 years ago) is 64 bit but I'd really like to confirm what's there right now.
I've tried dmesg and uname -a but neither gives me a reassuring confirmation of which architecture I have running at the moment!
Is there a way I can check?

"uname -a" gives you some information about the kernel image you are running. If you get x86_64 in the output, you are running 64-bit kernel and this means that your CPU is 64-bit capable.
To see information about your CPU, execute:
cat /proc/cpuinfo
Sometimes you will get all necessary information straight away from the output, but in other cases some further googling may be necessary.

Thanks - I think on freenas it's actually sysctl -a, which I found by googling the above on freenas when it didn't work - I found it says "kernel.ident: FREENAS32" - which looks worthy of further investigation. Thanks. – phatmanace – 2013-05-28T17:07:06.027
I don't know what BSD puts in here, and also, this is what the processor can support, not necessarily what the kernel is built as. – Rich Homolka – 2013-05-30T16:12:47.083

In FreeNAS 8, the System Information tab in the web-based GUI lists the FreeNAS Build, which identifies whether the image is 32-bit or 64-bit.
For example, *-x86 (32-bit) is shown as:
And for *-amd64 (64-bit):

mine says thisFreeNAS-8.3.0-RELEASE-p1-x86 (r12825) - so I guess 32 bit? – phatmanace – 2013-05-28T20:46:58.147
Yes, that sounds right. If you look at the hosted images for that release, there are separate folders for 32-bit and 64-bit. The x86 version is compiled for older 32-bit machines (but will also run on 64-bit architectures).

What does uname -m say? From my FreeBSD info, it should be either i386/i686 (32 bit) or amd64 (64-bit).
The 'FREENAS32' you found is a kernel/system build config file name. It does not necessarily indicate the bit size (though you hope the FreeNAS folks are consistent with their naming conventions).
