HP/Phoenix BIOS Summary
The System ROM contains the POST (power-on self-test) routines, and the
BIOS: the System BIOS, video BIOS (for models with an integrated video
controller), network BIOS (for models with a network controller), and low
option ROM. This chapter, and the following one, give an overview of the
following aspects:
• menu-driven Setup with context-sensitive help (in US English only), de-
scribed next in this chapter.
• The address space, with details of the interrupts used, described at the
end of this chapter.
• The Remote Power-On (RPO), which is the mechanism for turning on the
computer remotely from the network, described later in this chapter.
• The Power-On-Self-Test or POST, which is the sequence of tests the com-
puter performs to ensure that the system is functioning correctly, de-
scribed in the next chapter.
The system BIOS is identified by the version number HA.07.xx. The
procedure for updating the System ROM firmware is described on page 38.
