Introduction to Linux - A Hands on Guide
This guide was created as an overview of the Linux Operating System, geared toward new users as an exploration tour and getting started guide, with exercises at the end of each chapter.
For more advanced trainees it can be a desktop reference, and a collection of the base knowledge needed to proceed with system and network administration. This book contains many real life examples derived from the author's experience as a Linux system and network administrator, trainer and consultant. They hope these examples will help you to get a better understanding of the Linux system and that you feel encouraged to try out things on your own.

my problem is on installing nvidia driver on fc12 32bit but,
first of all,as i understood the pae kernel requires more than 4gb of ram,i have a 2.2 ghz cpu with 2 gb ram,but when i run command:uname -r
it answers: 18.104.22.168-127.PAE [i have fc12 32 bit]
when we try to download linux we have a 32bit edition or 64bit edition,do we have an edition which is only for pae?
when we install for example the 32bit edition on a computer with more than 4gb of ram then the kernel automatically will change to be a pae kernel??
thanks in advance
I read a few days ago - I believe on the Ubuntu web site - that "Ubuntu 10.04 32 bit installs a PAE kernel IF it detects more than 4 GB of RAM". I have 8 GB and when I ran the installer it did - so I can use my RAM. When I installed it with 1 GB RAM it installed a non-PAE kernel. Perhaps the Fedora installer is not as "smart". However, if the PAE kernel is working on your 2 GB system, Great! If you upgrade RAM at a later date it should be ready.
As to the recommendation to use the 64 bit edition... The Ubuntu site says of the 64 bit edition
Not recommended for daily desktop usage
I would agree whole heartedly. If you do not have software which needs 64 bit, stick with the 32 bit edition. It is sad but the 64 bit versions of software are not yet ready for prime time - even though 64 bit processors have been around for quite a while. Some day things will catch up - when 256 bit processors have been around for a decade
As to the nVidia driver... If you post the version of the driver, how you installed it, what specific problems you are seeing perhaps someone will be able to help.
p.s. Just as a test I bumped the memory on my non-PAE install from 1 GB to 5 GB. The kernel is still non-PAE and only 3 GB of memory is available. So perhaps the Fedora installer is smarter after all.

Other posts in this thread seem to have corrected that misunderstanding.

A kernel is built PAE or non PAE, so if you mean that "change" phrase literally, no.
A distribution might include two or more different kernels and select between them automatically during install. The results you reported imply Fedora did not do that for PAE vs. non PAE. But some other distribution might.

Strongly disagree. I used 64-bit Debian on my laptop for a while. Everything worked, including Flash and Java. (I never got into Wine on that install but that would have been a pain on 64-bit, yes). 64-bit support is pretty damn good these days.
If you do not have software which needs 64 bit, stick with the 32 bit edition.
This is true, however I would modify it as "...and you don't have > 4GB RAM, stick..."
Most modern distro have a multilib capability available so the 32 bit apps can be run on a 64 bit.
But there are the purists still pushing 32 bit with justification. So the PAE kernel will allow a larger memory footprint on the 32 bit system. Not everyone around the world will be upgrading to a 64 bit system. Too many 32 bit systems out there that will be used for a long time.
