Summary of the HP/Phoenix BIOS
Power Saving and Ergonometry
The network chip sends a signal over the External Start connector, where it
is received by the special network remote power chip. This in turn switches
on the main power supply.
The PC starts normally from whatever operating system is installed, just as if
the power supply had been switched on from the external power switch.
The display does not itself need to have RPO. If a password has been set, the
Start with keyboard locked
option must be enabled, to allow the oper-
ating system to boot.
Activity within the Setup Program
Since the user is not physically present, the level of security must be tighter.
There must be a distinction between the user-boot process, and the RPO-
boot process. HP provides all the necessary
Setup
options to keep users
from interfering with the computer during the remote session.
Administrators can set the management package to toggle on options like:
•
Keyboard lock mode: This offers the same suite of security features as the
external “keyboard lock” button (keyboard, mouse, reset and power but-
ton disabled).
•
Floppy disable: this makes sure the computer cannot be disrupted by re-
booting from a diskette.
RPO is available when the POST routines have finished executing. It is
initialized by an SMI signal which is triggered from the mains power button.
A power failure when the computer is in RPO mode will deactivate the RPO
feature. RPO is intended for resource management (such as virus cleaners,
nightly backups, etc.), not for crisis management (thunderstorm recovery,
power failure, etc.).
