Efi Commands - HP Integrity rx2660 User's & Service Manual

The EFI Boot Manager loads EFI applications (including operating system OS first stage loader)
and EFI drivers from an EFI-defined file system or image loading service. Non-volatile RAM
(NVRAM) variables point to the file to be loaded. These variables contain application-specific
data that is passed directly to the EFI application. EFI variables provides system firmware with
a boot menu that points to all the operating systems, even multiple versions of the same operating
systems.
The EFI Boot Manager enables you to control the server booting environment. Depending on
boot option configuration after the server is powered up, the Boot Manager presents you with
different ways to bring up the system. For example, you can boot to the EFI Shell, to an operating
system located on the network or residing on media in the server, or the EFI Boot Maintenance
menu.
The following options are available in the EFI Boot Manager menu
• Boot from File: Allows you to launch a specific application without adding it as a boot option.
When you select this option, a menu displays devices to choose your boot file from. Selecting
a disk device then displays subdirectories and executable applications on that device. Search
the subdirectories to find the correct file to boot from.If you choose a LAN device to boot
from, you can boot the file from a remote server. The remote server must be set up ahead
of time to recognize bootp requests from your server.
You can also launch a specific application without adding it as a boot option. In this case,
the EFI Boot Manager searches the root directories and the \EFI\TOOLS directories of all
of the EFI system partitions present in the system for the specified EFI application.
• Add Boot Entry: Adds a boot entry to the EFI Boot Manager. This works similarly to Boot
freom File, but adds the file to the boot menu as a new entry instead of just booting the file
once. You must specify a name for the boot entry to be added, and you can add ASCII or
UNICODE arguments to the applocation being launched.
• Remove Boot Entry: Deletes a specific boot option.
• Change Boot Order: Controls the relative order in which the EFI Boot Manager attempts to
execute boot options. For help on the control key sequences you need for this option, see
the help menu.
• Manage BootNext Setting: Selects a boot option to use only once (the next boot operation).
• Set Automatic Boot Timeout: Defines the value in seconds before the system automatically
boots without user intervention. Set this value to zero to disable the timeout feature.
• Exit: Returns control to the EFI Boot Manager menu. This displays the active boot devices,
including a possible integrated shell (if the implementation is so constructed).
