System Overview Power Consumption As an ENERGY STAR partner, HP has determined that this product meets the ENERGY STAR guidelines for energy efficiency (Windows 2000 and Windows 98 only). This value is only achieved when “Suspend to RAM” (S3 mode) is enabled. To enable Suspend to RAM, enter the PC’s Setup program by pressing F2 during startup and select the Power menu. In normal mode power consumption will be around 45W.

The Nvidia GeForce3 Ti200 card has 2 outputs, VGA and DVI. Either the VGA or the DVI output can be used, the outputs cannot be used for dual-monitor displays (unlike the GeForce2 MX). For more information, refer to the Technical Reference Manual - HP Business PC Technology available in PDF (Acrobat) format from www.hp.com/go/vectrasupport.
System Features ATI Rage 128 Pro and ATI Rage 128 Ultra Graphics Card Some Vectra VL420 PC models are supplied with an ATI Rage 128 Pro or Ultra graphics card. The ATI Rage 128 Pro has 16MB of video memory. The ATI Rage 128 Ultra is identical to the ATI Rage 128 Pro except that it has 32MB of video memory. A low profile version of both of these cards is also available for the VL420 small form factor, the only difference between the standard and low profile version is the height of the bracket.
System Features Audio The audio solution on the VL420 is the Analog Devices AD1885 integrated AC’97 audio solution. The AD1885 interfaces directly with the South Bridge chip and performs all digital operations, such as sample rate conversions and synthesis, as well as mixing and processing the analog signals. An optional Sound Blaster Live 5.1 audio card is also available for the minitower. All models have a Line In jack, Line Out jack and Microphone In jack connector located on the rear panel.
System Features Network All models have an Integrated Intel® Pro/100 VE Network Adapter (10 Base-T/100 Base-TX LAN Interface). An optional 3COM LAN card is also available, a low profile version is available for the small form factor. If you install a LAN card, integrated LAN is not automatically disabled. However you can disable the integrated LAN controller in the PC’s Setup program. The Intel LAN boot ROM setup can be launched by pressing CTRL-S while booting your PC.

4 BIOS Overview This chapter describes the BIOS features for HP Vectra VL420 PCs.
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.
BIOS Overview Advanced Menu The Advanced menu allows you to configure the setting of all motherboard components such as IDE devices, LAN, audio and I/O ports. Security Menu In the Security menu you can configure your password settings. Boot Menu In the Boot menu you can change your boot settings, including enabling/disabling quickboot mode.
BIOS Overview BIOS Addresses This section provides a summary of the main features of the HP system BIOS. System Memory Map Reserved memory used by accessory boards must be located in the area from C8000h to EFFFFh.

BIOS Overview PCI Interrupt Request Lines PCI devices generate interrupt requests using up to eight PCI interrupt request lines. PCI interrupts can be shared; several devices can use the same interrupt. However, optimal system performance is reached when minimizing the sharing of interrupts.
BIOS Overview Checkpoint Code POST Routine Description D6 Control is in segment 0. To check key and verify main BIOS checksum. If either is pressed or main BIOS checksum is bad, go to check point E0 else go to check point D7. D7 To pass control to Interface Module. D8 Main BIOS runtime code is to be decompressed. D9 Control to be passed to main BIOS in shadow RAM. Boot Block Recovery Code Check Points. E0 OnBoard Floppy Controller (if any) is initialized.
BIOS Overview Checkpoint Code POST Routine Description 24 To do any setup before Int vector init. 25 Interrupt vector initialization about to begin. To clear password if necessary. 27 Any initialization before setting video mode to be done. 28 Going for monochrome mode and color mode setting. 2A Different BUSes init (system, static, output devices) to start if present. 2B To give control for any setup required before optional video ROM check.
BIOS Overview Checkpoint Code POST Routine Description 59 Hit message cleared. message displayed. About to start DMA and interrupt controller test. 60 DMA page register test passed. To do DMA#1 base register test. 62 DMA#1 base register test passed. To do DMA#2 base register test. 65 DMA#2 base register test passed. To program DMA unit 1 and 2. 66 DMA unit 1 and 2 programming over. To initialize 8259 interrupt controller. 7F Extended NMI sources enabling is in progress.
BIOS Overview Checkpoint Code POST Routine Description AA Initialization after E000 optional ROM control is over. Going to display the system configuration. AB To build MP table if needed. AC To uncompress DMI data and execute DMI POST init. B0 System configuration is displayed. B1 Going to copy any code to specific area. 00 Copying of code to specific area done. Going to give control to INT-19 boot loader.
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.
The Technical Reference Manual contains the following documents downloadable from the web site www.hp.com/go/support in PDF format: • Introduction & HP Business PC Overview Describes how to use the Technical Reference Manual and provides a brief overview of the most recent HP Business PCs. • Product Description The document you are reading.
