Undefined Terminal Types
If an undefined terminal type from the DEFINE TERMINAL option menu is entered,
the menu prompts the user to enter a valid terminal type, and the menu is redis-

Resetting the Terminal: If the user enters a terminal type that is valid
(according to the DEFINE TERMINAL option menu) but is not the correct type for the

the Diagnostic Operating Instruction panel is displayed, and the user is required
to go through the DEFINE TERMINAL process again.

been turned off and then turned on (standalone mode) or after the diagnostics
program has terminated (Online concurrent mode).
The CD-ROM drive from which diagnostics were loaded cannot be tested.
The SCSI adapter (or circuitry) controlling the CD-ROM drive from which diag-
nostics were loaded cannot be tested.
Running Online Diagnostics
Consider the following when you run the Online Diagnostics from a server or a disk:
The diagnostics cannot be loaded and run from a disk until the AIX operating
system has been installed and configured. After the AIX operating system has
been installed, all three modes of operation are available.
The diagnostics cannot be loaded on a system (client) from a server if that
system is not set up to boot from a server over a network. When the system is
