Re: [gentoo-user] Which arch do I have ?

[Benjamen R. Meyer]

As you have an Intel Core Duo, you should have the EMT64E version -
Intel's version of the AMD64 instruction set - thus x86-64 compatible.

Best place to check is Intel's website - here's what I found:

http://processorfinder.intel.com/details.aspx?sspec=sl9dv
http://developer.intel.com/design/mobile/core/duodocumentation.htm

With EMT64E, you will be able to compile for 64-bit mode using the
x86-64 builds. (You can only use Intel64 if you have the Itanium procs
if memory serves.)

However, unless you specifically install the x86-64/AMD64/64-bit
version, you will have a 32-bit x86 environment and kernel. You can
upgrade if you like...see other threads for that info.

HTH,
