x86_64 packages on Pentium D 945: why?
Hi
Why installing SuSE 9.3 or SuSE 10.x on a PC with a Pentium D 945 I get installed as default the x86_64 instead of the i586/i686 packages? Is the Pentium D 945 a 64 bit processor? Shouldn't it be a 32 bit processor? Thanks Enrico |
If the x86_64 packages are working then you have a 64bit CPU. The Pentium D range has EM64T which translates to 64bit.

Pentium D was released when Intel already had EMT64 standard. You wouldnt be able to install X86_64 packages unless you installed linux using an X86_64 Distro disc. Once you install a X86_64 Distro any extra programs you install are X86_64 by default. |

The Linux Kernel developers appear to be very proud the fluent ability to use x86 (32bit) packages. Most noteably OpenOffice, Java and flash Firefox plugins are only available in 32bit packages. you need 32bit as well as x86_64 X packages to use Nvidia Drivers. But dont forget where ever possible x86_64 packages are better Does such a mixed system works well? Mostly yes since the 32bit and x86_64 programs work well together, some problem occur when you manually install programs from source of installing from rpm command use yast whereever possible. |

it has /usr/lib (32-bit) and /usr/lib64 (default 64-bit) subsystems If you want pure 64-bit, then simply uninstall (using Yast, don't try to delete folder as this will cause a lot of problems) 32-bit libs/apps on 64-bit system kernel is 64-bit (you can't run 32-bit drivers) Quote:
as i mentioned before thanks to 32-bit subsystem suse 64-bit will run 32-bit apps without any problem. |

The NVIDIA .bin compiler need 32bit libraries your right you do still need to use the x86_64 drivers 32bit ones dont work suse rpms dont need them though |
