HP/Phoenix BIOS Summary
The System ROM contains the POST (Power-On Self-Test) routines, and the BIOS: the
System BIOS, video BIOS, and low option ROM. This chapter, together with the following
one, give an overview of the following aspects:
• menu-driven Setup with context-sensitive help, described next in this chapter.
• The address space, with details of the interrupts used, described at the end of this
chapter.
• The Power-On-Self-Test or POST, which is the sequence of tests the computer performs
to ensure that the system is functioning correctly, described in the next chapter.
The system BIOS is identified by the version number
HO1xyyzz
(refer to the section “BIOS
Update Crisis Recovery Procedure” in the chapter “System Board” for a definition). The
procedure for updating the System ROM firmware is described in the section “Updating
the System ROM” in the chapter “System Board.”
Note that the messages in this section make reference to the “HP Kayak Workstation.” For
an explanation of this, see the section “Special Notice for Users” in the Preface of this
document.
Using the HP Setup Program
To run the Setup program, press
F2
while the initial “Kayak” logo is displayed immediately
after restarting the Personal Workstation.
Alternatively, press
Esc
to view the summary configuration screen. By default, this
remains on the screen for 20 seconds, but by pressing
F5
once, it can be held on the screen
indefinitely until
F1
is pressed again.
The band along the top of the Setup screen offers the following menus: Main, Advanced,
Security, Boot, Power and Exit. These are selected using the left and right arrow keys.
For a more complete description, see the User’s Guide that was supplied with the Personal
Workstation.
Main Menu
The Main menu presents a list of fields, for example, “PnP Operating System” (selects
whether the BIOS or Plug and Play operating system configures Plug and Play devices);
“Reset Configuration Data”; “System Time” “System Date” and “Key Click”.
By default the “Reset Configuration Data”, item is set to No. Selecting Yes, will clear the
system configuration data.
