I used x86 - bzImage to boot my machine and 'uname -a' shows this :- Linux phx4 3.7.1 #3 SMP Sun Dec 23 16:28:20 IST 2012 x86_64 x86_64 x86_64 GNU/Linux where I see x86_64 arch (and not x86_64) ??? What is the difference between arch/x86 and arch/x86_64 ? -- Shraddha
x86 is a 32-bit Processor architecture. x86_64 is the 64-bit Processor architecture. Software (including Linux kernel) designed for a 32-bit processor can run on both a 64-bit as well as a 32-bit processor, however software designed for 64-bit processor can't be executed on a 32-bit processor. ~Gaurav On Sun, Dec 23, 2012 at 4:58 PM, Shraddha Kamat <sh2008ka@gmail.com> wrote:

Very old days gone by , 32bit systems was known as 'i386' and 64bit system was called x86_64. ( If at all there were 64bit systems). Then we moved into and started calling x86 (32-bit system ) and x86_64 (64-bit system) Then kernel Dev's have got rid of this distension and name everything as x86. That is within, src/arch folder you will only find x86 folder. Thanks.
