Yep, I've now caught at least 2 people on other lists
installing IA-64 on Dell's new EM64T systems. I guess the
influx of Dell desktops with EM64T is causing a lot of
confusion.
[ SIDE NOTE: I'm sure the fact that Debian doesn't list
AMD64 as a port on its ports page (because it's not an
official port release yet, just in test) is also causing
people to assume IA64. ]
Here's the typical names of Linux ports as they match up to
products:
Vendor Common Official ISA Products
------ ------ -------- -------- -----------------
AMD AMD64 x86-64 x86-64 Athlon/64/Opteron
Intel EM64T IA-32e x86-64** Pentium-4/Xeon-MP
Intel IA64 IA-64 IA-64 Itanium/2
AMD64 and EM64T are essentially the same, and support the AMD
x86-64 (**NOTE: what Intel calls IA-32e, a slight subset of
x86-64) instruction set architecture (ISA). In a nutshell,
Linux/AMD64 aka Linux/x86-64 releases and packages (e.g.,
.x86_64.rpm) run on _commodity_ Athlon64/Opteron as well as
newer Pentium 4/Xeon MP systems.
IA64 is _completely_different_ and only offers a subset of
x86 compatibility in hardware (and Intel has even moved to
using Digital's former FX!32 software because it's faster).
IA-64 products are _Itanium_, and _never_ Pentium series.
