You can run Solaris 8 Interactive Installation Program (and the Device Configuration Assistant) two ways, as a:
Graphical user interface, which requires a local or remote CD-ROM drive or network connection, video adapter, keyboard, and monitor
Character-based user interface, which requires a local or remote CD-ROM drive or network connection, keyboard, and monitor; you can run the Solaris 8 Interactive Installation Program's character-based user interface with tip(1)
The content and sequence of instructions in both the graphical user interface and the character-based user interface are generally the same, with only slight differences.
If the Solaris 8 Interactive Installation Program detects a video adapter for the system, it uses the graphical user interface, and if it does not, it uses the character-based user interface.
