CentOS for i686 computers

Posted 10 January 2012 - 06:09 AM

Just downloaded CentOS to run on one of my servers. But when I try to install it onto my server, it tells me that my computer is i686 and the kernel is for x86_64. Is there a different download for i686? I cant seem to find one.

Yes, software like that usually comes in 32 bit (i386/i586/i686) and 64 bit (x86_64) versions.

Looking through some of the CentOS download mirrors, I found this page. It gives you a choice to download i386, which should work fine for a i686 processor (if a tad slower).

i386 and i686 are just different versions from Intel's x86 (32 bit) line of processors, all of which are backwards-compatible with each other. So as far as differences goes for the end-user, there really isn't one. Perhaps a very very slight performance edge for the higher numbers, and some added features to the actual CPU, but as far as the differences between compiled software, there none to bother talking about. - If you've got a processor build in the last 15 years, and there is a i686 version available, grab that. Otherwise i386 works fine on pretty much all PC and laptop processors.

If you want technical details on the differences, I'd suggesting just Googling for them. The Wikipedia articles should give you the basics.
