    The server we are running is RedHat Enterprise 4 i686 and the updates we are getting from Cpanel are rhel-i386-es-4.

    Does this sound correct to you guys?

    The "i386" is a platform that encompasses everything from the 386 to the high end non-64bit chip AMD and Intel processors. However you can run the i386 on the 64bit processors in standard 32 bit mode. "i386" is widely used to describe the intel/AMD chip based world that runs DOS and Windows operating systems.

    As my wife says "same smell, different nostril" ...

    i386 and i686 are 2 ways of denoting the same thing!

    The old original 80386 computers from more than 2 decades ago
    had software listed at "i386" to indicate it was for the Intel 80386
    and that designation was carried to refer to all PCs through the
    present even though the 80386 is long since history.

    A newer designation is "i686" which is just more modern updated
    way to refer to PCs (80686 refers to Pentiums and beyond).

    The i386 and i686 designations in software basically just refer
    to code written for PCs whether that be Intel based or compatible
    such as AMD processors, etc.

    Now the i686 should not be confused with i64 which is something
    entirely different completely. The newer i64 designation refers
    to 64 bit code for only the very newest 64 bit processors.
