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
