– Enabling the Boot to SMS Menu option
Causes the system to automatically stop at the System Management Services
menu during the boot process. Enabling this option is equivalent to pressing 1 on
the attached ASCII terminal (or F1 on a graphics terminal) while the system
initialization indicators display on screen.
– Enabling the Service Mode Boot from Saved list option
This selection causes the system to perform a service mode boot using the
service mode boot list saved in NVRAM. If the system boots AIX from the disk
drive and AIX diagnostics are loaded on the disk drive, AIX boots in service mode
to the diagnostics menu.
Using this option to boot the system is the preferred way to run online diagnostics.
– Enabling the Service Mode Boot from Default List option
This selection is similar to "Service Mode Boot from Saved List", except the
system boots using the default boot list that is stored in the system firmware. This
is normally used to try to boot customer diagnostics from the CD-ROM drive.
Using this option to boot the system is the preferred way to run standalone
diagnostics.
– Enabling the Boot to Open Firmware Prompt option
Causes the system to automatically enter open firmware prompt (also called the
OK prompt). This option should only be used by service personnel to obtain
additional debug information.
