The Alternative Architecture Special Interest Group (AltArch SIG) is happy to announce the release the x86 32-bit version of CentOS Linux 7. This architecture is also known as i386 or i686. You can get this version of CentOS from the INFO page.
This version of CentOS Linux 7 is for PAE capable 32 bit machines, including x86 based IOT boards similar to the Intel Edison. It joins the 64-bit ARMv8 (aarch64) architecture as a fully released AltArch version.
Work within the AltArch SIG currently continues on the 32-bit ARMv7, 64-bit PPC little-endian, and 64-bit PPC big-endian architectures.
