IBM RS/6000 Server User Manual


 
In the case of AIX this is a supported option only for the CHRP compliant version. If
you receive a message saying:
No Operating System Installed
information in non-volatile storage could have been lost, as would happen if the
battery had been removed. In order to recreate this value issue the bootlist command
under AIX with the appropriate parameters as to the location of the operating system
in a particular Hard disk. Please see the explanation of the bootlist command in your
AIX documentation.
The Software Default option, if supported by the operating system, lets you select
the default operating system to start the system. This option may not be supported
by all operating systems.
The Install From option produces a list of devices, for example the CD-ROM, where
the operating system is installed from. You select one of the devices and the system
searches the device for an operating system to install and if supported by the oper-
ating system in that device, the name of the operating system displays.
The Boot Sequence option provides a list of devices that can be selected for the
boot list. Up to five devices are supported.
The Multiboot Startup option toggles between OFF and ON and selects if the Multi-
boot menu invokes automatically on startup or not. To toggle, select the Multiboot
Startup option, then press the Enter key.
This selection enables you to view and change the custom boot list (the sequence
used to search devices for operating system startup code).
