I chose to boot from DVD.I chose installing fedora from the first screen then a black window contains lines I didn't understand appeared then after a long time another screen appeared says what language to use..until I reached to the a screen asks me where do you want to install packages from when I chose disk driver nothing happened and it went back to point to choose a driver there were 5 drivers in the list I choose one at a time a blue screen appeared says welcome to ferora9 and then nothing happened can you sole it to me?

Have you read this?

Welcome to LQ.

1) Fedora 9 is obsolete and unsupported, no more updates.
Fedora 12 was released a week ago.
The long term supported version is CentOS (Redhat) 5.4 .

2) I have never installed any drivers in any Linux at
install time. Everything is included for an install.
Drivers needed for very special things can be installed
(much) later, after you have seen your install work.

I have always used redhat. however since moving from fedora 7 to 9 many applications ( APPGEN UNFORM VSIFAX ) are no longer supporting the fedora versions. You mentioned centos. I have read that centos is compatible with hedhat enterprise 5 ( which is acceptable to these applications).
I also want to migrate from 32 to 64. Is Centos the way to go?

It seems that you reached the graphical login screen. Try to log in with the username that Fedora required to be created by you during installation.

CentOS 5.4 is a free copy of Redhat EL 5.4 .
No difference.
Redhat EL is only supported by a paid subscribtion,
but is open source, so exact copies exist as
CentOS and Scientific Linux ( + a few more.)
