This section outlines the differences between the Red Hat Enterprise Linux 6 and Red Hat Enterprise Linux 5 installation procedures. Depending on which release of Red Hat Enterprise Linux 5 you are migrating from, not all of the options and techniques listed here may be relevant to your environment, as they may already be present in your Red Hat Enterprise Linux 5 environment.
2.1. Kernel and Boot Options
You may perform memory testing before you install Red Hat Enterprise Linux by entering memtest86 at the boot: prompt. This option runs the Memtest86 stand alone memory testing software in place of the Anaconda system installer. Once started, Memtest86 memory testing loops continually until the Esc key is pressed.
The rdloaddriver kernel parameter is now needed to define the order of module loading, instead of the old scsi_hostadapter option.
