Selectable boot settings

When you set the Selectable Boot Settings option to Enabled, you can select the
worldwide port name of the fibre-channel hard disk from which you want to start up
(boot). When this option is set to Enabled, the node starts from the selected
fibre-channel hard disk, ignoring any IDE or SCSI hard disks that are attached to
your server. When this option is set to Disabled, the Boot ID and Boot LUN
parameters have no effect.
The BIOS code in some new systems supports selectable start up, which
supersedes the Fast!UTIL selectable start up setting. To start from a fibre-channel
hard disk that is attached to the DS4000 FC2-133, select the attached fibre-channel
hard disk from the system BIOS menu.
Note: The Selectable Boot Settings option for the DS4000 FC2-133 applies to only

Restore default settings

You can use the Restore Default Settings option to restore the DS4000 FC2-133
default settings and NVRAM.

an NOVRAM update operation was run from the BIOS Update Utility program
(option U or command line /U switch). If the BIOS Update Utility program has not
been used to update the default NOVRAM settings since the adapter was installed,
the factory settings are loaded.
