Writes to the hard disk drive boot sector can be disabled, for instance as a protection against
viruses.
Under the “Start-Up Center” sub-menu, the Setup program not only allows the user to select
which devices are enabled or disabled for booting up the system, but also indicates their order
of precedence when more than one is enabled: network, flexible disk drive, CD-ROM drive, or
hard disk drive.
POWER MENU
The “Power” menu allows the user to set the standby delay. It also allows the system
administrator to decide whether the network, serial ports, mouse, or space bar are enabled as a
means of reactivating the system from
Standby or Suspend. It is also possible to specify
whether the network is enabled as a means of reactivating the system from Off, using the
remote power-on (RPO) facility (as described in the next Chapter).
HP/PHOENIX BIOS DESCRIPTION
The System ROM contains the BIOS (System BIOS, video BIOS and low option ROM), an the
power-on self-test routines that allows you to view the results of the diagnostics as well as a
corrective action message (error message utility).
This chapter and the following two chapters give an overview of the HP/Phoenix BIOS. The
information is divided into three main sections:
• The Remote Power-On (RPO), which is the mechanism for turning on the PC remotely
from the network; and the Desktop Management Interface (DMI), which is the new method
for storing and accessing information about the PC, described in Chapter 5.
• The Power-On-Self-Test or POST, which is the sequence of tests the PC performs to
ensure that the system is functioning correctly, described in Chapter 6.
• menu-driven Setup with context-sensitive help (in US English only), described earlier in
this chapter.
• The address space, with details of the interrupts used, described next.
The system BIOS is identified by the version number GW.07.xx. The procedure for updating
the System ROM firmware is described in Chapter 2.
Summary configuration screen
You can press [F2] while the initial “Vectra” logo screen is being displayed to run the
Setup
program (as described in the previous sub-sections). Alternatively, you can press [ESC] to view
the summary configuration screen, an example of which is depicted on the next page. By
default, this remains on the screen for 20 seconds, but by pressing [F5] once, it can be held on
the screen until [F5] is pressed again, or until [F1] is pressed. Pressing [F10] will cause the PC
to be turned off.
