You can run the Solaris 8 Interactive Installation Program and for Intel systems, the Device Configuration Assistant, with a GUI or with a CLI.
GUI – Requires a local or remote CD-ROM drive or network connection, video adapter, keyboard, and monitor.
CLI – Requires a local or remote CD-ROM drive or network connection, keyboard, and monitor. You can run the Solaris 8 Interactive Installation Program CLI with tip(1).
If the Solaris 8 Interactive Installation Program detects a video adapter for the system, it automatically displays the GUI. If the Solaris 8 Interactive Installation Program does not detect a video adapter it automatically displays the CLI. The content and sequence of instructions in both the GUI and the CLI are generally the same.
