i386 vs. X86_64
I'm going to be downloading Fedora Core 4 for my desktop PC.
I was curious what the difference is between i386 and X86_64?
I have a P4 3.ghz pc. So would I need the X86_64 because I run an Intel?
Any help would be greatly appreciated!
Wes

The x86_64 version is for 64bit processors. You'll want the i386 version.

SRPM= Source RPM. RPM = installed files with no source.
FYI, if given the option you want i686 over i386, 486, and 586. 686 is closer and will optimize your speed more, but you can any any (3-6)86 to successfully install.

Well right now I'm downloading the SRPM Fedora Core 4 cds to install. They don't have them in i686.
Will the SRPM cds work just as good as the rpm?

For an install? I would think so, but the end result will be alot bigger as you save the source for everything and then compile it all from said source. SRPMs normally install SPEC, then they are built from source, unlike normal RPMs which are binary. I would doubt on an install you would be doing this yourself, but the end effect would be a longer installtion, I would think. But you would end up with a more optimized install and all the sources installed too.
Maybe someone with more than a general knowledge of deora/red hat installs can verify this or supply correct info.

Yeah. I'm not to worried about space. I got a 160GB hard drive so I'm sure I will have tons of space.
Now I currently have a couple partitions I want to keep. It is possible to install Fedore Core 4 over my current Whitebox install without having to format all partitions right? Theres actually just one partition I need to keep which has all my websites, email and music.

AFAIK, most linux flavors will install "over the top" by default. SuSE and most others I have used do this unless you specifically tell them to side by side.

Cool, well I plan on doing a full install anyways. I got tons of space and I'm not going to be putting more much on except my websites and music. So I don't mind if it takes up a bit of space, I'm sure its not going to go over 5GB - but I'm not Linux expert
