I'm trying to get my iso ready for my newbuild that doesn't have an o/s, but can't find the right download for my new processor.   When I download from my old computer the file name includes the processor (AMD 64) on this computer, which, I don't think would work on the new one (i7) I want it for.  How can I find the right one, please? Thanks

What is the difference between 32-bit and 64-bit Ubuntu? I've heard the 64-bit platform performs better and can detect more than 4GB of RAM. Also, while some apps haven't ported to 64-bit yet, ia32-libs lets a 64-bit machine run them.  If so, why not promote 64-bit over 32-bit?

The error message is      This kernel requires an x86-64 CPU,but only detected an i686 CPU. Unable to boot - please use a kernel appropriate for your CPU.   How can I overcome this?

Why is it that:   a 32-bit OS, when installed on a 64-bit CPU, can run old 16-bit applications,  but if you install a 64-bit OS it can't run those applications directly and need some sort of emulation (that doesn't always work perfectly)?     To be more specific, I have an 64-bit processor (Intel Core 2 Duo). When I had Windows XP and Windows 7 (both 32-bit) installed, they could run old DOS and 616-bit Windows applications.   Now I have installed the 64-bit edition of Windows 7. Why can't it run those same applications anymore?

I have a 32-bit system which runs on a 64-bit processor. How do I convert it to be all-64-bit, without re-installing? I have seen somewhere that it is doable as a result of .

lead me to be quite shocked with my current system. The CPU in my workstation is an i7 with hyperthreading enabled, and cat /proc/cpuinfo produces 4 'cpu's.  That all given, my PC can generate over a 16 in all the load average slots from 1 minute to 15 minutes while compiling packages for Gentoo, but still be working perfectly for all other tasks as well. I've even seen it as high as 24, though it was starting to slow down at that point. How does this work, if 1.0 is supposed to represent one core at full utilisation?

I have an AMD laptop, which has AMD APU (e1-2500). I don't really like the speed of it and would love to upgrade to faster APU. There are some AMD APUs available in ebay. So the question is:   What do I need to check to be sure that a new APU will work without problems?

I recently purchased an HP Stream 7, which I was led to believe would have Windows 8.1 64-bit installed. However, it has 32-bit Windows, even though it has a 64-bit processor. Installing 64-bit has been problematic, and I found the reason is the 32-bit UEFI. Is there a way to change it or replace it with a 64-bit UEFI? Are there any other options for installing Windows 8.1 64-bit? Or is this impossible presently?  Thank you.

I have a Dell Studio 17. It's a few years old, and I wanted to upgrade the processor. It currently has an Intel Core 2 Duo T5750 @ 2.00GHz  My question is how can I find out which processors are compatible?

I have just ran lshw to get some information about  a machine I know nothing about, and I just wanted to confirm something.  Does this basically mean it is a dual core 64 bit processor that is installed?  *-logicalcpu:0     description: Logical CPU           physical id: 0.1               width: 64 bits               capabilities: logical        *-logicalcpu:1                 description: Logical CPU                physical id: 0.2                   width: 64 bits                capabilities: logical   Looking further down I see this    *-cpu:1       physical id: 1       bus info: cpu@1       version: 6.7.6       serial: 0001-0676-0000-0000-0000-0000       size: 3150MHz       capabilities: vmx ht       configuration: id=0     *-logicalcpu:0          description: Logical CPU          physical id: 0.1          capabilities: logical     *-logicalcpu:1          description: Logical CPU          physical id: 0.2          capabilities: logical   Which makes me almost certain it is dual core but not convinced on the 64 bit.  Any help for this n00b would be greatly appreciated!

I'm confused. Running Fedora Linux, lscpu yields:  Architecture:            i686 CPU op-mode(s):          32-bit, 64-bit ...   But when I try to install a 64-bit program (Chrome) I get error like:     Package /....x86_64.rpm has incompatible architecture x86_64. Valid architectures are ['i686', 'i586', 'i486', i386']   I'm less interested in being able to install Chrome and more interested in why lscpu says that my CPU can run in 64-bit mode; clearly this can't mean I can run 64-bit programs. Can anyone clarify?

I am trying to use a file repository for updating linux/ubuntu on a non-connected machine. The architecture for this machine (uname -a):  x86_64 GNU/Linux   The results of dpkg --printarchitecture are:  amd64   It is a Trusty Tahr amd64 machine, and it specifically says this, for example, in the aptitude sources.list file. Also, the "About this Computer" in ubuntu specifically says the machine is 64-bit. So, I installed the amd64 packages on the machine. However, when I try to do apt-get update, I get errors such as:  W: Failed to fetch file:/var/spool/apt-mirror-trusty/mirror/archive.ubuntu.com/ubuntu/dists/trusty/main/binary-i386/Packages  File not found   So, in other words, even though it is a 64-bit machine, apt is inexplicably trying to read i386 packages. Why is it doing this and how can I make it use the 64-bit packages?  Note that there is nothing in sources.list that specifies i386.  The only uncommented line in the sources.list file is:  deb file:///var/spool/apt-mirror-trusty/mirror/archive.ubuntu.com/ubuntu trusty main restricted universe multiverse

I'm running  on a Windows 7 (RTM) 64-bit host. When I create a new virtual machine and try to install 64-bit Windows 7 on that VM, I get "this CPU is not compatible with 64-bit mode."  Is there a way to create 64-bit virtual machines?

I have a 64-bit (amd64 a.k.a. x86_64) Debian or Ubuntu installation. I need to run 32-bit (i386/i686) programs occasionally, or to compile programs for a 32-bit system. How can I do this with a minimum of fuss?  Bonus: what if I want to run or test with an older or newer release of the distribution?

I've got a 32-bit Ubuntu installation running on 64-bit hardware. Now that , I would like to switch to 64-bit without having to reinstall the OS.  This is one of the :  Shawn installed his system using the 32-bit version of Ubuntu, but his hardware is 64-bit and he wants to switch over. He manually installs the amd64 versions of dpkg and apt, replacing the i386 versions and changing which architecture is used as the default; then he installs the amd64 ubuntu-minimal package; then he installs the amd64 ubuntu-desktop package. Over time the remaining i386 packages are replaced automatically on upgrade.  However, when trying to follow the instructions in there, I cannot find any 64-bit version of dpkg or apt.  Did this user story got implemented in a different way in the final spec, or do I need to do something differently?  In short, how can I switch my 32-bit installation to 64-bit?

This  gives this comparison chart for the four Windows 8 Editions (Core is usually just called Windows 8). I notice specifically, about half-way down, the max physical processors is listed as 1 for "Core" and 2 for all other.  In the second image i see physical processors listed as 8 in a Windows 8 Task Manager.  My question is, what is the limit then? Can anyone verify the article or the screenshot?  Was this a mock-up? Another Edition? (Server perhaps?)      To clarify, i am looking for links to official microsoft.com articles detailing these specifications.  I have been unable to find any.
