Sometimes you'll get a question like "Why don't you use the x86_64 naming convention like the rest of Linux?". (There is more than one thing wrong with that question) AMD64 is what x86-64 officially became. Intel doesn't technically use AMD64, but instead uses a compatible 64 bit instruction set. As far was what the OP should use, depends on the CPU. Not all Xeon's support AMD64 but any recent ones should. I'm not all up on my Dell models, but I think the 1950 shouldn't have any troubles with AMD64. However at the end of the day your choices are AMD64 or i386 as ia64 is for itanium's. The Itanium instruction set is completely different than AMD64 and no amount of coaxing will make it work. -- Adam Vande More
