My mother board is Asus P4P800-Delux, and after I tried to install Red Hat 9.0 I noticed it gave me two options to boot from as if I had dual boot setup. Both options were Red Hat 9.0. Also I could not install RPMs correctly.

I don't think your problem are related w motherboard. Please post your /etc/lilo, and some more details about you system, is windows installed?
Also give more details about your trouble w rpm install.

Okay, I thought it was my motherboard because in this thread http://www.linuxquestions.org/questi...hreadid=197176 the guy is having the same problems I think. I didn't have windows installed. When I double click on an RPM Itloads files then just quits. Usually they promt for options and things right?

Things on Linux are a bit different from Windows!

Open a terminal, and do the following:
(type): su - it will be asked the root password, type this password, you will be as superuser, and the prompt will be changed to a # sign.
(type): rpm -i package_file.rpm [enter]

This will install the package in your system. Could happen some issues related with dependencies a true nightmare for newbies (like I). If you have this kind of problems, ask in the forum and someone will help you. Or try to install Mandrake it is a good distribution related to this problem because there is a tool (urpmi - Mandrake exclusive) to solve this dependencies issues.
