I have no idea why, but perhaps it's to do with getting Linux's and Wine's memory layout models to coexist in the same space. They are mutually incompatible to Wine has to do some amazing stuff to get it to work. Perhaps 64 bit presents a saner linear memory model than 32 bit and so Wine has more breathing wrong.

You do. It's called x86_64 in kernel-speak :-) gentoo calls it amd64 These days the 32 and 64 bits x86 trees have been merged into one, called x86. The vast majority of the trees were the same with a few differences here and there so a merge was appropriate and easier to maintain. 64 bit x86 is really just an extension of 32 bit in terms of the C code, it certainly isn't, and doesn't warrant, a different arch -- Alan McKinnon alan dot mckinnon at gmail dot com -- gentoo-user@lists.gentoo.org mailing list

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,

Let's say this processor supports 64 bits, what whould I gain from
migrating to x86_64 I mean would it be faster??? I've never
owned/worked on a 64bit machine before so excuse my lack of knowledge
:)
The primary advantage is larger memory space, and more native use of the
entire processor. I'm running it b/c I want to be - not b/c I need the
memory space, I'm not pushing 4GB for Physical RAM which is primarily
what it is about.
From my understanding, you won't gain much if any in speed. The
processor is still the same clock rate. 64-bit programs may (not sure,
someone verify?) be bigger as the opcodes are larger.
You can run any of the following configs:
1) pure 32-bit
2) pure 64-bit
3) mixed 32-64 bit (multi-lib)
HI again,
the T2250 is a Core Duo and not a Core 2 Duo. It only supports 32 bits
instructions.

regards,

Well here you go, thanks for clearing this up.
#3 will be the largest install as you have a lot of duplications since
you are hosting both a 32-bit and 64-bit environment. However, with #2
you might not get a lot of programs since there are quite a few that
have not been fully ported to 64-bit modes. You're running #1 now.
So not much is gained for now.

I'm sorry but I'm just used to call it this way, most of distros I have tried in the past call it this way, anyway I'll try to memorize it. Cool. Nothing worse than composing a decent post, only to then have to explain that you weren't using THIS definition but rather THAT one. It's an easy enough error to make (do it myself too) so no worries sorry for the question: why does #ls /usr/src/linux/arch/ show alpha/ blackfin/ h8300/ m32r/ mips/ ppc/ sh64/ um/xtensa/ arm/ cris/ i386/ m68k/ parisc/s390/ sparc/ v850/ avr32/ frv/ ia64/ m68knommu/ powerpc/ sh/ sparc64/ x86_64/ but not amd64? kh So, the only good reason to move to amd64 is when you buy a 64 bit machine I have 1G RAM and it's a laptop doesn't serve huge databases so I guess despite if my CPU is 64 or 32 bits, I'll just stick with the 32 version, works great... Agreed. You have no obvious benefits from a 64 bit arch. You also get to not have to struggle with flash wondering if it will work this time or not ;-) -- gentoo-user@lists.gentoo.org mailing list
Re: [gentoo-user] Which arch do I have ?
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.
