To select a boot mode, select a number and press Enter. The item corresponding to
the selected number toggles from disabled to enabled. If the same number is
selected again, the item toggles from enabled to disabled. If a boot mode is enabled,
the boot mode selected is performed, and the disabled/enabled selection is reset to
disabled. Following is a description for each boot mode:
– Boot to SMS Menu
When this selection is enabled, the system boots to the System Management
Services (SMS) menu.
– Service Mode Boot from Saved List
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.
– Service Mode Boot from Default List
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.
– Boot to Open Firmware
When this selection is enabled, the system boots to the open firmware prompt.
This option should only be used by service personnel to obtain additional debug
information.
