2 System Features Main Memory
There are two 168-pin DIMM slots on the system board for installing main memory. You can install 133MHz SDRAM modules. These are available in 64, 128, 256 and 512 MB memory modules. You can install only one 512 MB module. A maximum of 512 MB is supported. You can use ECC or non-ECC memory modules. However, single/multiple biterror processing is not done by the 815 chipset.

Processors

The VL400 is equipped with either a single Socket 370 Intel Celeron or socket 370 Intel Pentium III processor. Socket 370 is a conversion of Slot 1 (used previously by Celerons and Pentium IIs) to a socket, running at the same bus protocol as the Pentium II (the GTL+ bus protocol). The processor is connected to the system board through a Plastic Pin Grid Array (PPGA) 370 Socket. The reduction in size achieved by the Socket 370 Celeron is due to the integration of the L2 cache on the processor die. Like the Celeron processor, the Pentium III comes in a 370-pin socket (PGA370) package. To find out more about Socket 370 Celeron technology, refer to the Technical Reference Manual - Vectra Technology.

BIOS Overview

This chapter describes the BIOS features for the HP Vectra VL400 PC models.
4 BIOS Overview BIOS Summary

BIOS Summary

HP Vectra VL400 PCs contain a Phoenix BIOS (Basic Input Output System), which was customized by Phoenix for use on the VL400. The system ROM contains the POST (power-on self-test) routines, and the BIOS: the System BIOS, video BIOS, and 3Com LAN boot ROM. The system BIOS is identified by the version number IP.xx.xx. The latest BIOS version for your PC and instructions for updating the BIOS can be downloaded from the HPs Support Web site at: www.hp.com/go/vectrasupport. This section covers: The BIOS Setup program Power saving BIOS addresses The order in which POST tests are performed Beep codes.
Using the HP Setup Program
Press F2 to run the Setup program, when the HP logo is displayed immediately after restarting the PC. Press F8 to enter the Boot menu. Use the boot menu to select the order of the devices the PC will use to start (boot) from. 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. The Setup screen offers five menus: Main, Advanced, Security, Boot, Power and Exit. These are selected using the left and right arrow keys.

Protection Against Viruses
The VL400 has several features to protect it from viruses: Hard Drive Master Boot Sector Protection: It is impossible to write on the boot sector or to format the hard disk when this feature is enabled. This protection is enabled in the Security - Hardware protection menu of the Setup program. PC Boot Block Protection: The boot block is protected by a physical switch on the system board (switch 4) and a software switch. When flashing the BIOS, the switch must be closed; HPs BIOS flash program closes the software switch before flashing the BIOS. BIOS Flash Protection: BIOS flashing is protected by two software switches.

Boot Menu

The QuickBoot Mode option allows the system to skip certain tests while booting. This decreases the time needed to boot the system. The Boot-time Diagnostics screen enables the user to display either the HP logo or diagnostics screen during POST. Boot Device Priority allows you to select the order of the devices from which the BIOS attempts to boot the operating system. During POST, if the BIOS is unsuccessful at booting from one device, it will then try the next one on the list until an operating system is found. Hard Disk Drives allows you to choose the hard drive you want to boot from. Removable Devices allows you to choose which drive letters you want to assign to removable devices.

Power Menu

The Power menu has the following fields: State After Power Failure. This field allows you to select the state that the PC will place itself into after a power failure. For example, if you set this field to Off, the PC will not start up after a power failure. Setting this value to Auto means that the PC will return to the state it was in before the power failure took place. Advanced Power Management (APM) fields. These fields allow you to set APM features, such as the timeout before the PC goes into suspend mode, and whether the PC will wake up (or power on) from modem or network card activity. Advanced Configuration and Power Management (ACPI) field. It allows you to enable or disable the Suspend to RAM feature available with ACPI operating systems (such as Windows 2000).
4 BIOS Overview Power Saving and Ergonometry
Power Saving and Ergonometry

Soft Power Down

Soft Power Down is available with the Windows NT operating system. If users want to shut down their PC, they are able to do so directly from the Windows NT interface. There is no longer any need to physically switch off the PC. The hardware to do this is contained in the ICH chipset. This chipset is described in detail in Technical Reference Manual - HP Vectra Technology.

Safe Off

Safe Off is available with the Windows 95 and Windows 98 operating systems. If users attempt to shut down the operating system when an application is open and has not been saved, they are requested to save their work before the computer can be powered off. In Windows 2000, the equivalent to HPs Safe Off is provided by the operating system. The hardware to do this is contained in the ICH chipset. This chipset is described in detail in Technical Reference Manual - HP Vectra Technology.

Power Management

You can reduce the PCs overall power consumption by using Power Management to slow down the PCs activity when it is idle.
Operating System Power Management
Operating systems such as Windows 98 SE, Windows NT 4.0 and Windows 2000 differ in their power management capabilities. Refer to your operating system documentation for more information.
APM Power Management Modes
Suspend In Windows 95 for example, you can enter this low power state by clicking Start Suspend. You can also set the timeout value (time of inactivity before going into Suspend mode) in the PCs Setup Program. In this mode, the LED on the PCs font panel blinks green.
ACPI Power Management Modes (Windows 2000 and Windows98 SE only)
Standby In Windows 2000 for example, you can enter this low power state by clicking Start Shut Down, then selecting Stand by and clicking OK. In this mode, the LED on the PCs font panel blinks green. There are two forms of Standby: normal (s1) and Suspend to RAM (s3), which is a lower power consumption state than normal Standby. You can use Suspend to RAM by enabling this feature in the PCs Setup Program. To do this, press F2 during startup, then set Suspend to RAM in the Power menu to enabled. If this feature is disabled, the normal (s1) Standby is used. Hibernate (s4) This is available in Windows 200 only and is lower power state than Standby. In Windows 2000, you can enter this low power state by clicking Start Shut Down, then selecting Hibernate and clicking OK. In this mode, the LED on the PCs font panel is off.
4 BIOS Overview BIOS Addresses

BIOS Addresses

This section provides a summary of the main features of the HP system BIOS. This is software that provides an interface between the computer hardware and the operating system.

System Memory Map

Reserved memory used by accessory boards must be located in the area from C8000h to EFFFFh.
- 0000 03FF - 0000 04FF - 0009 FCFC00 - 0009 FFFF 000A_0000 - 000B_FFFF 000C 0000 - 000C 7FFF 000C 8000 - 000F FFFF 000E 0000 - 000F FFFF - FF FFFF - 1FF FFFF -3FF FFFF -1FFF FFFF FFF80000 - FFFF FFFF Real-mode IDT BIOS Data Area Used by OS Extended BIOS Data Area Video RAM or SMRAM (not visible unless in SMM) Video ROM Adapter ROM, RAM, memory-mapped registers System BIOS (Flash/Shadow) Memory (1 MB to 16 MB) Memory (16 MB to 32 MB) Memory (32 MB to 64 MB) Memory (64 MB to 512 MB) 512 KB BIOS (Flash)
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 64 KB of addressable I/O space comprises 8-bit and 16-bit 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.
I/O Address Ports 0000 - 000F 0020 - 0021 002E - 002F 0040 - 0043 0060, - 0081 - 0083, 008F 0092 00A0 - 00A1 00C0 - 00DF 00F0 - 00FF 0170 - 0177 01F0 - 01F- 027F 02E8 - 02EF 02F8 - 02FF 0372 - - 037A 03B0 - 03DF 03E8 - 03EF 03F0h- 03F5 03F6 03F7 03F8 - 03FF 04D0 - 04D- 067B 0778 - 077B 0CF8 - 0CFF Function DMA controller 1 Master interrupt controller (8259) NS364 Configuration registers Timer 1 Keyboard controller (reset, slow A20) Port B (speaker, NMI status and control) Bit 7: NMI mask register RTC and CMOS data Manufacturing port (POST card) DMA low page register PS/2 reset and Fast A20 Slave interrupt controller DMA controller 2 Co-processor error IDE secondary channel IDE primary channel LPT 2 Serial port 4 (COM4) Serial port 2 (COM2) IDE secondary channel, secondary floppy disk drive LPT1 VGA COM3 Floppy disk drive controller IDE primary channel Floppy disk drive controller COM1 Interrupt edge/level control LPT2 ECP LPT1 ECP PCI configuration space

DMA Channel Controllers

Only I/O-to-memory and memory-to-I/O transfers are allowed. I/O-to-I/O and memory-to-memory transfers are disallowed by the hardware configuration. The system controller supports seven DMA channels, each with a page register used to extend the addressing range of the channel to 16 MB. The following table summarizes how the DMA channels are allocated.
DMA controller Channel Free Free if not used for parallel port in Setup Floppy disk controller Free if not used for parallel port in Setup Used to cascade DMA channels 0-3 Free Free Free Function

Interrupt Controllers

The Interrupt Requests (IRQ) are numbered sequentially, starting with the master controller, and followed by the slave.
IRQ (Interrupt Vector) INTR IRQ0 IRQ1 IRQ3 IRQ4 IRQ5 IRQ6 IRQ7 IRQ8 IRQ9 IRQ10 IRQ11 IRQ12 IRQ13 IRQ14 IRQ15 System Timer Keyboard Controller Used by serial port if enabled Used by serial port if enabled Free if not used for parallel port or audio Floppy Disk Controller LPT1 RTC Available for PCI devices, if not used by ISA board or USB port Available for PCI devices, if not used by ISA board or USB port Available for PCI devices, if not used by ISA board or USB port Mouse Co-processor IDE Primary channel IDE Secondary channel. Free unless disabled
Interrupt Request Description
PCI Interrupt Request Lines
PCI devices generate interrupt requests using up to four PCI interrupt request lines (INTA#, INTB#, INTC#, and INTD#). PCI interrupts can be shared; several devices can use the same interrupt. However, optimal system performance is reached when minimizing the sharing of interrupts.
4 BIOS Overview Order in Which the POST Tests are Performed
Order in Which the POST Tests are Performed
Each time the system is powered on, or a reset is performed, the POST is executed. 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. Note, though, that 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.

Checkpoint Code 02h 03h 04h 06h 08h 09h 0Ah 0Bh 0Ch 0Eh Verify Real Mode Disable Non-Maskable Interrupt (NMI) Get CPU type Initialize system hardware Initialize chipset with initial POST values Set IN POST flag Initialize CPU registers Enable CPU cache Initialize caches to initial POST values Initialize I/O component POST Routine Description

4 BIOS Overview HP e-DiagTools Preboot Diagnostic (Beep Codes)
HP e-DiagTools Preboot Diagnostic (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 PCs monitor. If, however, your PC is unable to display an error message (for example, when you graphics controller has failed), it will emit a buzzing sound. This is the eDiagTools preboot diagnostic. 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.
Number of Beeps Meaning System OK Processor absent, not correctly connected or ZIP socket not closed Power supply is in protected mode No memory, bad memory modules, incompatible memory module Graphics card 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, then listen for the signal again. The e-DiagTools preboot diagnostic, as well as emitting a beep sequence, also encodes troubleshooting information (such as the PC models, serial number, and failing component) 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.
