Dear Mark, the i686 was used to address Pentium Pro or better systems. If you are running 64 bit then the system is better. The i686 are for the 32 bit applications. If the 32 bit and the 64 bit libraries are not the same exact version of each other on the 64 bit machine, that might be a problem. Or maybe your 32 bit applications really need an older 32 bit library. So far in the work I am doing with testing installing certain applications on a RHEL5.3 box I am finding the RHEL5.3 releases of 32 bit libraries to work just fine whether it has the designation of i386 or i686.
