EFI/POSSE Commands
This section describes the EFI/POSSE commands developed for the server.
NOTE EFI and Pre-OS System Environment (POSSE) are similar. EFI is an Intel specification, whereas POSSE is
the HP implementation that aids HP support.
help
Provides information on the EFI shell commands. It also has an additional feature to aid those familiar with the BCH menus to
adjust to their equivalent functions in EFI.
Syntax
help [-b] <category>
help [-b] <cmd>
help [-b] bch <bchmenu> <bchcmd>
Parameters
-b Enable page breaking
category Category of commands to view help on commands
cmd Shell command name on which to provide verbose information
bch Display the list of BCH commands and their corresponding EFI
bchmenu BCH menu name taken from the top level of the BCH menu
bchcmd BCH command on which to display information
Operation
If help is invoked with no parameters, it displays a list of shell command categories. To list all of the commands within a
category, the user should type help <category> (see examples). If invoked with the -b switch, any output longer than one
page pauses after each page is displayed. If a shell command name is used as a parameter, verbose help is displayed for that
command.
If help is invoked with the bch option, it displays a list of BCH commands and their corresponding EFI/POSSE commands. It
instructs the user to repeat the command line followed by a menu name for more information on that menu. If help is invoked
followed by bch and a menu name, it displays a list of commands that appear under that BCH menu. The user may then
invoke help followed by bch, the menu name, and a BCH command name to display information on that command. This
would point the user to the command that has taken the place of that BCH functionality, or will inform the user that the
functionality no longer exists. As a shortcut, the user may enter help followed by bch and a BCH command name to go
straight to that command.
