NOTE The power consumption figures given in the table above are valid for the standard configuration as shipped. For more information, refer to the product’s data sheet at HP’s web site: www.hp.com/go/desktops

When the computer is turned off with the power button on the front panel, the power consumption falls below 4W, but it is not zero. The special on/off method used by these computers considerably extends the lifetime of the power supply. To reach zero power consumption in “off” mode, either unplug the power outlet or use a power block with a switch.

BIOS Overview

BIOS Summary

HP Vectra VL420 PCs contain an American Megatrends Inc. BIOS (Basic Input Output System). The system ROM contains the POST (power-on self-test) routines, and the BIOS: the System BIOS, video

BIOS, and Intel LAN boot ROM.

The system BIOS is identified by the version number BB.MM.mmLL

,where: BB = BIOS letter, MM = Major

BIOS version, mm = Minor BIOS version, LL = localization of the BIOS.

The latest BIOS version for your PC and instructions for updating the BIOS can be downloaded from HP’s

Vectra support Web site at: www.hp.com/go/vectrasupport .

This section covers:

• The BIOS Setup program

• Power saving

• BIOS addresses

• POST tests

• Beep codes.

Entering the Configuration and Diagnostics menu

To enter the Configuration and Diagnostics menu on your HP Vectra VL420 PC, restart the computer and press F8 when the HP logo screen appears. The Configuration and Diagnostics menu displays the default order of devices the PC will start (boot) from. This order can be modified in the boot menu of the Setup program, see “Using the HP Setup Program” below.

Press F12 to boot (start) on the network. This option will only work if your PC and the network is configured correctly.

Alternatively, press Esc to view the summary configuration screen. By default, this remains on the screen for 20 seconds, but by pressing the Pause key once, it can be held on the screen indefinitely until any key is pressed.

Press F10 to run HP Diagnostics.

Using the HP Setup Program

In the Configuration and Diagnostics menu press F2 to run the Setup program.

The Setup screen comprises six menus: Main, Advanced, Security, Boot, Power and Exit. These are selected using the left and right arrow keys.

A brief summary of what settings can be configured in each of these menus is described below:

HP I/O Port Map (I/O Addresses Used by the System)

Peripheral devices, accessory devices and system controllers are accessed via the system I/O space, which is not located in system memory space. The 64KB of addressable I/O space comprises 8-bit and 16bit registers (called I/O ports) located in the various system components. When installing an accessory board, ensure that the I/O address space selected is in the free area of the space reserved for accessory boards (100h to 3FFh).

Although the Setup program can be used to change some of the settings, the following address map is not completely BIOS dependent, but is determined partly by the operating system. Note that some of the

I/O addresses are allocated dynamically.

POST Tests

The POST is executed each time the system is powered on, or a reset is performed. The POST process verifies the basic functionality of the system components and initializes certain system parameters.

The POST starts by displaying a graphic screen of the Hewlett-Packard logo when the PC is started.

Devices, such as memory and newly installed hard disks, are configured automatically. The user is not requested to confirm the change. Newly removed hard disks are detected, and the user is prompted to confirm the new configuration by pressing F4 .

NOTE The POST does not detect when a hard disk drive has been otherwise changed.

During the POST, the BIOS and other ROM data is copied into high-speed shadow RAM. The shadow

RAM is addressed at the same physical location as the original ROM in a manner which is completely transparent to applications. It therefore appears to behave as very fast ROM. This technique provides faster access to the system BIOS firmware.

The following table lists the POST checkpoint codes written at the start of each test:

BIOS Overview


BIOS Overview

HP e-DiagTools Preboot Diagnostics (Beep Codes)

When your PC starts up, its BIOS performs a Power-on Self Test (POST) to test your hardware configuration for any problems. If a problem is detected during the POST, an error is displayed on your

PC’s monitor.

If, however, your PC is unable to display an error message (for example, when your graphics controller has failed), it will emit a buzzing sound. This is the e-DiagTools preboot diagnostic. In the event of a problem with your PC immediately after the buzzing sound, a series of beeps is emitted.

If you hear a series of beeps, you should count them as this will help you detect the cause of the problem.

Meaning

• If you hear the buzzing audio signal: system OK

• No buzzing audio signal: no power, PC is unplugged, power supply is down or system board has failed.

Processor absent, not correctly connected or processor socket not closed

Power supply is in protected mode

No memory, bad memory modules, incompatible memory module

Graphics solution problem

PnP/PCI initialization problem

Corrupted BIOS. You need to activate crisis recovery procedure.

Defective system board

Note that for Memory (code 3), Video Card (code 4), and PnP/PCI (code 5) errors, e-DiagTools preboot diagnostic will only detect them after a 15-second timeout.

If you miss the beep code, turn off the PC. Then press the on/off power button for five seconds or more and listen for the signal again.

The e-DiagTools preboot diagnostics, as well as emitting a beep sequence, also encodes troubleshooting information (such as the PC model, serial number and failing components) into a coded audio signal.

During a support call, this coded signal can then be decoded by the HP Service Provider to provide immediate and effective assistance.
