x86_64 is the common set of configurations and libraries for 64-bit computers. You should be able to look up the model number of your computer, or the motherboard and BIOS at boot time. Or you can grab a live CD, such as the CentOS 5.4 or Ubuntu live CD, and boot with the 64-bit live CD to determine if it's compatible with your system. If you can, use 64-bit operating systems. There are some lingering compatibility issues, but you can make much more full use of your hardware with a 64-bit operating system, and virtualize a 32-bit operating sytem if you need it. You cannot do the reverse. There are other architectures, which a home PC is unlikely to have. These include ARM (common in some fascinating netbooks and smartphones) and sparc (no longer in production, Sun computers got bought). _______________________________________________ CentOS mailing list [email protected] http://lists.centos.org/mailman/listinfo/centos
