Select Boot Device - IBM 265 Service Manual

Software Default: This option is used when more than one operating system is
installed on the same disk drive. AIX does not support multiple operating systems on a
single disk drive. Multiple AIX images can be installed on separate disk drives; the
desired disk drive can be selected for booting using the Select Boot Device function in
System Management Services or the AIX diagnostic service aid Display or Change
Bootlist.
If Software Default is chosen from this menu, a line similar to the following is
displayed:
–> 1
This indicates the current version of AIX that is installed on the system.
If you are running on AIX and you receive the following message:
No Operating System Installed
this indicates that information in nonvolatile storage could have been lost, as would
happen if the battery had been removed. To re-create this value, run the Select Boot
Device option on this menu.
Select Install Device: Produces a list of devices, for example the CD-ROM, from which
the operating system is installed. Select a device and the system searches the device
for an operating system to install and if supported by the operating system in that
device, the name of the operating system displays.
Select Boot Device: Provides a list of devices that can be selected to be stored in the
boot list. Up to five devices are supported.
OK Prompt: Provides access to the open firmware command prompt. This option
should only be used by service personnel to obtain additional debug information.
Multiboot Startup: Toggles between OFF and ON and selects whether the Multiboot
menu invokes automatically on startup.

Select Boot Device

Select this option to view and change the custom boot list, which is the sequence of
devices read at startup.
