The Standalone Diagnostic CDROM contains all programs and applications necessary to run Diagnostics. This includes the latest version of AIX, device drivers, device configuration methods, diagnostic applications, and ODM stanzas.
Device support that is not on the Diagnostic CDROM must be supported by Diagnostic Supplemental Media.
Starting with AIX 4.1, the Rock Ridge based CDROM File System was used for the Diagnostic CDROM. The Rock Ridge CDROM File System supports directory levels deeper than 8, mixed-case file names and a file structure similar to AIX file systems.
