As the current RHEL release (4) is only available in CDs, not in DVD but it is possible to create a RHEL bootable DVD ISO from these CDs using Chris Kloiber’s mkdvdiso.sh script file.
You have to follow some simple steps to create a RHEL bootable DVD ISO.
Step-1: Download mkdvdiso.sh from the below mentioned path.
http://mirror.centos.org/centos/build/mkdvdiso.sh
Step-2: Install the anaconda-runtime prerequisite package and its dependencies and run as described.
# rpm -q anaconda-runtime || yum -y install anaconda-runtime
Step-3: Put all the CD ISO files and mkdvdiso.sh in a specific directory and run the mkdvdiso.sh script to create RHEL bootable DVD ISO.
Step-4: But before running this script, change ISO files name like disk1.iso, disk2.iso, disk3.iso, disk4.iso and disk5.iso
# ls -1
mkdvdiso.sh
disc1.iso
disc2.iso
disc3.iso
disc4.iso
disc5.iso
Step-5: The following command will create a RHEL bootable DVD ISO named RHEL-U4-i386-AS-dvd.iso
# ./mkdvdiso.sh . $(pwd)/RHEL-U4-i386-AS-dvd.iso
These 5 steps will create your 5 RHEL CD ISO to single RHEL bootable DVD ISO.
