The HTTP dialog applies only if you are installing from an HTTP server (if you selected HTTP in the Installation Method dialog). This dialog prompts you for information about the HTTP server from which you are installing Red Hat Enterprise Linux.
Enter the name or IP address of the HTTP site you are installing from, and the name of the directory containing the variant/ directory for your architecture. For example, if the HTTP site contains the directory /mirrors/redhat/arch/variant;/, enter /mirrors/redhat/arch/ (where arch is replaced with the architecture type of your system, such as i386, ia64, ppc, or s390x, and variant is the variant that you are installing, such as Client, Server, Workstation, etc.). If everything was specified properly, a message box appears indicating that files are being retrieved from the server.
Next, the Welcome dialog appears.
Tip
You can save disk space by using the ISO images you have already copied to the server. To accomplish this, install Red Hat Enterprise Linux using ISO images without copying them into a single tree by loopback mounting them. For each ISO image:
mkdir discX mount -o loop RHEL5-discX.iso discX
