Special Notice for Users

The HP VISUALIZE Personal Workstation is made from a combination of high performance
Industry Standard components (for example, the Intel Pentium III processor) and desired HP
value added technologies (for example, HP VISUALIZE fx+ graphics cards). The HP VISUALIZE
Personal Workstation also shares some important technologies with the HP Kayak Workstations,
including certain processor system board features. Since these common technologies are used by
the HP VISUALIZE Personal Workstations and the HP Kayak Workstations, your HP VISUALIZE
Personal Workstation will occasionally make reference to “HP Kayak PC Workstations,” “HP
Kayak XU,” or “HP Kayak XW.” This is particularly true during the initial Power-On Self Test

and when you see MaxiLife LCD messages.

1. PCI and AGP power electrical specifications must be respected. For example, the maximum power
consumption for the PCI slot is 25 W. The total power PCI consumption must never exceed 85 W. For the
AGP slot, 2 A maximum at +5 V.

An attempt to draw too much current (such as, a short circuit across edge-connector pins, or an
accessory board that is not suitable for these Personal Workstations), will cause the overload
protection in the power supply to be triggered, and the Personal Workstation could fail to boot.

NOTE

When the Personal Workstation is turned off with the power button on the
front panel, the power consumption falls below the low power level (refer to
Table 1-5), but is not zero. The special on/off method used by this Personal
Workstation extends the lifetime of the power supply. To reach zero power
consumption in “off” mode, either unplug the Personal Workstation form the
power outlet or use a power block with a switch.

AGP Slot

The Accelerated Graphics Port (AGP) bus, provides a high performance graphics interface.
It uses a 66 MHz base clock, and provides a peak bandwidth of 528 MB/second.

AGP supports several modes, which are listed below. In its basic mode, AGP is very much like a 66 MHz
PCI bus; in a more advanced mode, pipelining is added along with special sideband signals, thereby
improving the bus performance. A double-clocking mechanism enables data transfers on both rising and
falling edges of the clock, which brings the maximum bandwidth to 528 MB/s: 66 MHz x 2
(double-clock) x 4 (bus width = 32 bit).

The different AGP modes include:

• Basic AGP: 66 MHz, PCI-like. Bandwidth: 265 MB/s.

• Pipelined AGP: 66 MHz + pipeline.

• Sideband AGP: 66 MHz + pipeline + sideband signals.

• Full AGP: 133 MHz equivalent (66 MHz with double clocking) + pipeline + sideband
signals. Bandwidth: 528 MB/s.

The AGP bus interface is explained in the section “Accelerated Graphics Port (AGP)
Controller.”

32 Chapter2

System Board

Accessory Board Slots

PCI Slots

There is a total of five Peripheral Component Interconnect (PCI) connectors on the system
board. From top to bottom, the PCI slots are numbered 1 to 5 (refer to the diagram on the
previous page). The third PCI connector has a special extension called ARO or FastRaid
connector (refer to the section “FastRAID Port” for details about this connector), into which
the HP FastRAID accessory board can be installed. The fifth PCI connector shares the
corresponding slot with an ISA connector. This slot is called a Combo (Combination) slot,
since a PCI board or an ISA board can be installed in it.

The system board and BIOS support the PCI specification 2.1. It fully supports PCI-to-PCI
bridges and multi-function PCI devices, and each of the five PCI slots has Master
capabilities.

The maximum supported power consumption per slot is 25W, either from the 5V or the

3.3V supply and must respect the electrical specifications of the PCI 2.1 specification. Total
power consumption for the PCI slots must not exceed 85W.

The power consumption of each PCI board is automatically reported to the system through
the two Presence Detect pins of each PCI slot. These pins code the following cases:

• No accessory board in the PCI slot.

• 7W maximum PCI board in the PCI slot.

• 15W maximum PCI board in the PCI slot.

• 25W maximum PCI board in the PCI slot.
This information is reported in the BIOS setup screen. If the total power used in the PCI

slots exceeds 85W, the BIOS will display a warning during the boot sequence.
In addition to these PCI slots, there are three other devices connected on the PCI Bus:

• 440GX AGPset chipset, bridge between the Processor Front Side Bus (FSB) and the PCI
bus.

• PIIX4E chip, bridge between the PCI and the ISA, USB and IDE buses.

• AIC 7880 chip from Adaptec, PCI to SCSI (wide) controller.

Devices on the PCI bus are explained in the section “Devices on the PCI Bus” in this
chapter.

ISA Connector

There is only one ISA connector provided on the system board. The corresponding slot is
shared with the PCI connector (Combo slot).

In addition to this ISA slot, the following devices (refer to the section “Devices on the ISA
Bus” in this chapter for more details about devices on the ISA bus) are also connected to
the ISA bus:

• Ultra I/O (NS 97317), which integrates one parallel port, two serial ports, a keyboard
and mouse controller (8042), a floppy controller and a battery backed-up Real Time
Clock + CMOS (RTC).

Chapter 2 33

System Board

Accessory Board Slots

• PIIX4E chip, bridge between the PCI and the ISA, USB and IDE buses.

• Two flash ROM sockets for 256 KB or 128 KB ROMs.

• Audio chip (AD1816 from Analog Device).

• IO APIC interrupt controller (Intel 82093).
The ISA bus interface is explained in the section “ISA Bus Interface” in this chapter.

FastRaid Port

A FastRaid port is provided on the system board through the ARO (RAIDport) connector.
This connector, aligned with the PCI slot 3, is to be used by a specific PCI accessory board,
called the ARO board. This board uses the ARO connector on the system board to directly
connect a SCSI hardware accelerator to the embedded Adaptec AIC 7880 controller. The
SCSI hardware accelerator chip, located on the ARO board, uses local memory to perform
hardware caching and also accelerates SCSI data striping when two hard disk drives are
used.

38 Chapter2

System Board

Chipset

Host Bridge Interface

The Pentium III Xeon processor supports a second level cache via a Dual Independent Bus
(DIB). All control for the L2 cache is handled by the processor. The Host Bridge provides
bus control signals and address paths for transfers between the processors FSB (host bus),
PCI bus, AGP and main memory. The Host Bridge supports a 4-deep in-order queue (i.e.,
supports pipelining of up to four outstanding transaction requests on the host bus). Due to
the system concurrency requirements, along with support for pipelining of address
requests from the host bus, the Host Bridge supports request queueing for all three
interfaces (Host, AGP and PCI).

Host-initiated I/O cycles are decoded to PCI, AGP or PCI configuration space.
Host-initiated memory cycles are decoded to PCI, AGP (prefetchable or non-prefetchable
memory space) or DRAM (including AGP aperture memory). For memory cycles (Host, PCI
or AGP initiated) that target the AGP aperture space in DRAM, the Host Bridge translates
the address using the AGP address translation table. Other host cycles forwarded to AGP
are defined by the AGP address map.

PCI and AGP initiated cycles that target the AGP graphics aperture are also translated
using the AGP aperture translation table. AGP initiated cycles that target the AGP
graphics aperture mapped in main memory do not require a snoop cycle on the Host bus,
since the coherency of data for that particular memory range will be maintained by the
software.

The chip can support one or two Pentium III Xeon processors, at up to 100 MHz FSB clock
frequency. Refer to the section “Host Bus” in this chapter for a description of the devices on
the Host Bus.

PCI Bus Interface

The Host Bridge/Controller provides the interface to a PCI bus interface operating at 33
MHz. This interface implementation is compliant with PCI Rev 2.1 Specification,
supporting up to five external PCI masters in addition to the PIIX4E Bridge chip and the
Adaptec AIC 7880 16-bit SCSI controller. The PCI-to-DRAM interface can reach a transfer
rate of over 100 MBytes/sec for streaming reads and over 120 MBytes/sec for streaming
writes.

Sequential PL-to-PCI memory write cycles are translated into PCI zero wait state burst
cycles. The maximum PCI burst transfer can be between 256 bytes and 4 KB. The chip
supports advanced snooping for PCI master bursting, and provides a pre-fetch mechanism
dedicated for IDE read.

Refer to the section “Devices on the PCI Bus” in this chapter for a description of the devices
on the PCI Bus.

AGP Bus Interface

A controller for the AGP (Accelerated Graphics Port) slot is integrated in the Host
Bridge/Controller. The AGP Bus interface is compatible with the Accelerated Graphics
Port Specification, Rev 1.0, and it can support up to 133 MHz data transfer rates. The Host
Bridge/Controller supports only a synchronous AGP interface, coupling to the host bus
frequency. AGP characteristics are described in detail in the section “Accelerated Graphics
Port (AGP) Controller” in this chapter.

Chapter 2 39

System Board

Chipset

Main Memory Controller

The main memory controller supports four DIMM sockets; Mem 1, Mem 2, Mem 3 and
Mem 4. Each socket can host a 168-pin SDRAM memory module, running at 100 MHz, and
can support unbuffered and registered memory modules. Each DIMM socket is connected
to the SMBus.

The Intel 440GX AGP set provides DIMM plug-and-play support via the Serial Presence
Detect (SPD) mechanism using the SMBus interface. The Host Bridge provides optional
data integrity features including ECC in the memory array. During reads from DRAM, the
Host Bridge provides error checking and correction of the data. The Host Bridge supports
multiple-bit error detection and single-bit error correction when the ECC mode is enabled
and single/multi-bit error detection when correction is disabled. During writes to the
DRAM, the Host Bridge generates ECC for the data on a QWord basis. Partial QWord
writes require a read-modify-write cycle when ECC is enabled.

The memory bus is 72-bits wide, comprised of 64 bits of data and 8 bits of ECC. Refer to the
section “Main Memory Bus” in this chapter for more detail on the main memory.

Read/Write Buffer

The Host Bridge defines a data buffering scheme to support the required level of
concurrent operations and provide adequate sustained bandwidth between the DRAM
subsystem and all other system interfaces (CPU, AGP and PCI).

System Clocking

The Host Bridge operates the host interface at 100 MHz, PCI at 33 MHz and AGP at
66/133 MHz. Coupling between all interfaces and internal logic is done in a synchronous
manner. The clocking scheme uses an external clock synthesizer (which produces reference
clocks for the host, AGP and PCI interfaces).

I/O APIC

I/O APIC is used to support dual processors as well as enhanced interrupt processing in
the single processor environment. The Host Bridge supports an external status output
that can be used to control synchronization of interrupts in configurations that use PIIX4E
with stand-alone I/O APIC components.

The PIIX4E, PCI/ISA Bridge Chip (82371EB)

The PCI-to-ISA/IDE Xcelerator chip, known as PIIX4E, is encapsulated in a 324-pin Ball

PCI to ISA/EIO Bridge

PIIX4E compatible with the PCI Rev. 2.1 specification, as well as the IEEE 996
specification for the ISA (AT) bus. On PCI, PIIX4E operates as a master for various
internal modules, such as the USB controller, DMA controller, IDE bus master controller,
distributed DMA masters, and on behalf of ISA masters. PIIX4E operates as a slave for its
internal registers or for cycles that are passed to the ISA or EIO buses.

ISA Bus Interface

As well as accepting cycles from the PCI bus interface, and translating them for the ISA
bus, the ISA bus interface also requests the PCI master bridge to generate PCI cycles on
behalf of a DMA or ISA master. The ISA bus interface contains a standard ISA bus
controller and data buffering logic. Refer to the section “Devices on the ISA Bus” in this
chapter for a description of the devices on the ISABus.

SMBus Controller

The System Management (SM) bus is a two-wire serial bus provided by the PIIX4E
controller. It runs at a maximum of 16 kHz. The SMBus Host interface allows the CPU to
communicate with SMBus slaves and an SMBus Slave interface that allows external
masters to activate power management events. The bus also monitors some of the
hardware functions of the main board, both during boot-up and run-time. All accesses to
the bus are handled by the main processor, via the PIIX4E SMBus registers. Refer to the
section “Devices on the SMBus” for a description of the devices on the SMBus, or to the
section “HP MaxiLife Utility” in this chapter for information on the MaxiLife ASIC.

IDE Controller

The PCI master/slave IDE controller (Bus Master capability and synchronous DMA mode),
supporting two devices is described in the section “Integrated Drive Electronics (IDE)” in
this chapter.

Chapter 2 43

System Board

Chipset

Enhanced USB Controller

The USB (Universal Serial Bus) controller provides support for the Universal Host
Controller Interface (UHCI). This includes support that allows legacy software to use a
USB-based keyboard and mouse. The USB supports two stacked connectors on the back
panel. These ports are built into the PIIX4E controller, as standard USB ports. The USB is
described in detail in the section “Universal Serial Bus (USB) Controller” in this chapter.

DMA Controller

The seven-channel DMA controller incorporates the functionality of two 82C37 DMA
controllers. Channels 0 to 3 are for 8-bit DMA devices, while channels 5 to 7 are for 16-bit
devices (see the section “DMA Channel Controllers” in the chapter “HP BIOS”). The
channels can be programmed for any of the four transfer modes: the three active modes
(single, demand, block) can perform three different types of transfer: read, write and verify.
The address generation circuitry supports a 24-bit address for DMA devices.

Interrupt Controller

Based on two 82C59 interrupt controllers. The two interrupt controllers are cascaded so
that 14 external and two internal interrupts are possible. In addition, PIIX4E supports a
serial interrupt scheme. It also supports the onboard I/O APIC controller 82093AA. A table
in the section “Interrupt Controllers” in the chapter “HP BIOS” shows how the master and
slave controllers are connected.

Counter / Timer

The chip contains a three-channel 82C54 counter/timer. Three counters are combined to
provide the system timer function, refresh request, and speaker tone. The counters use a
division of the 14.318 MHz OSC input as the clock source.

Serial EEPROM

This is the non-volatile memory which holds the values for the Setup program (they are no
longer stored in the CMOS memory). The Serial EEPROM is described in the section

“Serial EEPROM” in this chapter.

Hot Bus

Hot Bus

The Host bus of the Pentium III Xeon processors, also referred to as the FSB (Front Side
Bus), is implemented in the AGTL (Assisted Gunning Transceiver Logic)+ technology. This
technology features open-drain signal drivers that are pulled-up to 1.5 V through resistors
at bus extremities; these resistors also act as bus terminators, and are integrated in the
processor. If only one processor is installed, a terminating board must be installed in the
second processor slot.

The supported operating frequencies of the AGTL+ bus is 100 MHz. The width of the data
bus is 64 bits, while the width of the address is 32 bits.

The control signals of the Host bus allow the implementation of a “split -transaction” bus
protocol. This allows the Pentium III Xeon processor to send its request (for example, for
the contents of a given memory address) and then to release the bus, rather than waiting
for the result, thereby allowing it to accept another request. The Intel 440GX, as target
device, then requests the bus again when it is ready to respond, and sends the requested
data packet. Up to four transactions are allowed to be outstanding at any given time.

For the Host bus to run at 100 MHz while respecting the specified signal and timings, a
distributed mechanism is used on each AGTL+ signal. The following termination resistors
are used: 150 ohm on the system board (close to the 440GX), 85 ohm on the system board
between the two processor slots. The bus is routed with a star topology.

Intel Pentium III Xeon Processor

The Pentium III Xeon processor has several features that enhance performance:

• Single Edge Contact Cartridge (S.E.C.C) package technology first introduced on the
Pentium II processor. This packaging technology allows Pentium III Xeon processors to
implement the Dual Independent Bus Architecture and have up to 2 MB of level 2
cache. Note that like the Pentium Pro and Pentium II Xeon processors, level 2 cache
communication occurs at the full speed of the processor core.

• MMX™ technology instructions, which gives enhanced media and communication
performance.

• Streaming SIMD Extensions for enhanced floating point and 3D application
performance.

The Pentium III Xeon processor (core and cache memory) is packaged in a self-contained
Single Edge Contact (SEC) cartridge installed in a Slot 2 processor slot. The SEC cartridge
requires a 330-contact Slot 2 connector on the system board. It includes a processor chip,
tag and data SRAMS, and AGTL+ termination resistors, SMBus ROM, and SMBus
thermal sensing device.

The Pentium III Xeon processor requires two different voltages to supply the CPU core and
L2 cache. Each processor codes through Voltage Identification (VID) pins with the required
voltage level being 1.8 to 3.5V. Two VID sets are provided, one for the CPU core, and one
for the L2 cache. Each VID set is decoded by a Voltage Regulation Module (VRM), installed
in a VRM socket on the system board, which supplies the required power voltage to the
processor.

Chapter 2 45

System Board

Hot Bus

On HP VISUALIZE Personal Workstations there are two Slot 2 processor slots, along with
three VRM sockets. A single Pentium III Xeon processor for Slot 2 must be accompanied by
two VRMs inserted in VRM sockets 1 and 2 (from left to right). Single processor models
can be upgraded to a dual processor system by installing a second processor accessory in
the vacant slot. The second processor must be a Pentium III Xeon processor for Slot 2 of
the same speed and Level 2 cache memory capacity as the first, and same Level 2 cache
voltage. The VRM that was supplied with the second processor must be installed in the
vacant third VRM slot.

NOTE

When upgrading from a single processor to a dual processor with the
Hewlett-Packard processor accessory kit, you only need to check the processor
frequency speed and Level 2 cache memory capacity. This information can be
obtained by checking the label on the upper side of the processor. Processors
supplied with the Hewlett-Packard accessory kit are checked to ensure that
the Level 2 cache voltage is the same for all processors, and they have the
same frequency speed and Level 2 cache memory size.

It should be noted that Pentium III processors for Slot 1 are not compatible with Pentium
III Xeon processors for Slot 2. This means that you cannot upgrade a processor from a Slot
1 system to Slot 2.

The following table shows a comparison between the Pentium III Xeon processor for Slot 2
and Pentium III processor for Slot 1.

Bus Frequencies

There is a 14.318 MHz crystal oscillator on the system board. This frequency is multiplied
to 100 MHz by a phase-locked loop. This is further scaled by an internal clock multiplier
within the processor.

For example, the Pentium III Xeon 400 MHz processor multiplies the 100 MHz system
clock by 4. Switches 2, 3, 4 and 5 set the clock multiplier ratio.

this chapter. A table summarizing switches six through to ten is shown in the section
“System Board Switches” in this chapter.

The computer may execute erratically, if at all, or may overheat, or won’t boot if it is
configured to operate at a higher processor speed than the processor is capable of
supporting. This can cause damage to the computer.

If the switches are set to operate at a slower speed than the processor is capable of
supporting, this may also cause erratic behavior in some cases and would reduce the
instruction throughput in others.

Cache Memory

There can be either two integrated circuits (core + 1 cache = 512 KB L2 cache) or three
integrated circuits (core + 2 cache = 1 MB L2 cache) sealed within a single Pentium III
package. One of these contains the Level-2 (L2) cache memory chip; the other contains the
processor, which itself includes Level-1 (L1) cache memory.

The L1 cache memory has a total capacity of 32KB (16 KB data, 16 KB instructions). The
L2 cache memory has a capacity of 512 KB or 1 MB, and is composed of four-way
set-associative static RAM. Data is stored in lines of 32 bytes (256 bits). Thus two
consecutive 128-bit transfers with the main memory are involved in each transaction.

The amount of cache memory is set by Intel at the time of manufacture, and cannot be
changed.

Chapter 2 47

Optional Second Microprocessor

HP VISUALIZE Personal Workstations have dual processing capability. Installing a second
processor is only advantageous when the software can make use of parallel activity. In
particular, you need to be running a multi-threaded operating system that supports
multiprocessing (one that is MPS-ready), such as Windows NT. The Windows NT operating
system makes the best use of the Pentium III’s 32-bit architecture (though other operating
systems will also show some benefit if 32-bit application programs are run).

The following table summarizes the supported operating systems:

The two processors must be operating at the same processor speed, and both, or neither,
must support the processor internal ECC functionality.

Configuring Setup for Multi-Processing

HP V

ISUALIZE Personal Workstations support Symmetric Multi-Processing (SMP). When

adding a second processor, you must ensure that: (a) the “multi-processing” choice has
been made in the system Setup; (b) the operating system supports multi-processors.

In the case of Windows NT, it might be necessary to perform an upgrade from the MPS
uniprocessor to the MPS multi-processor version.

NOTE

The system Setup allows a choice between “mono or multi-processing”
operations. The “mono-processing” mode has been implemented in order to
support operating systems that rely on the “legacy” interrupt controller
82C59 and are not aware of I/O APIC controller 820093AA operation. Refer to
the section “Interrupt Controllers” in the chapter “HP BIOS” for further
details.

Main Memory Bus

Main Memory Bus

The memory bus is 72-bits wide, comprised of 64 bits of data and address information, and
8 bits of Error Correcting Code (ECC). The bus is connected to the Main Memory and to
the Host Bridge (Intel 440GX) chip.

HP V

ISUALIZE Personal Workstation models are supplied with a 128 MB unbuffered ECC

SDRAM memory module in one of the four DIMM slots, leaving the other slots free for
memory upgrades. If additional memory is required, up to 1 GB (4 x 256 MB) of unbuffered
memory may be installed. Memory upgrades are available in single 64 MB, 128 MB or 256
MB unbuffered ECC SDRAM modules.

Or, alternatively, the existing unbuffered memory modules may be replaced by Registered
ECC SDRAM memory modules. Memory can be upgraded to a maximum of 2 GB using
multiples of 512 MB Registered or unbuffered ECC SDRAM memory modules (4 x 512
MB). Both the 512 MB Registered and unbuffered memory modules were not available at
the time of introduction of the HP V

ISUALIZE Personal Workstations

NOTE

Unbuffered and Registered ECC memory modules are not compatible with
each other, and cannot be mixed.

Refer to the section “DIMM Sockets” in this chapter for information about the DIMM
sockets.

Mixing Memory Modules

Unbuffered and Registered ECC modules are not compatible with each other, and cannot
be mixed. If they have been mixed, this will be detected in the basic pre-boot tests when
you boot the system for the first time. The BIOS checks that the inserted DIMMs are
compatible with one another and, if it detects an error, reports it to MaxiLife. The error
message (shown below) will then be displayed on the LCD status panel.

Error Correcting Code Operation

Error correcting code (ECC) memory allows any single-bit error that occurs in any 72-bit
line of memory (64 data bits plus 8 parity bits) to be corrected (automatically and
transparently) by the host bridge chip.

The ECC detects single- and dual-bit errors. It can correct single bit errors during SDRAM
reads. The corrected data is transmitted to the requester (PCI or CPU) but not written
back to the SDRAM. A double-bit error would cause an NMI to be generated, and the PC
Workstation to be halted.

If more bits are faulty within any given 72-bit line, the effect is the same as it would have
been without error correction. The effect of executing a faulty instruction is always
unpredictable, and might cause the program to ‘hang’. The effect of reading a faulty data
word is often similarly unpredictable, but can sometimes be tolerated (for instance, it

might merely appear as a corrupted pixel on a video display).

Ultra-Wide (16-bit) Small Computer System Interface (SCSI)
Controller

The Adaptec AIC-7880 Ultra-wide SCSI PCI controller is integrated on the HP VISUALIZE
Personal Workstation system board. Data is transferred at 40 MB/s on 16-bit wide,
single-ended bus. The controller is fitted with a 16-bit SCSI flat cable with five connectors,
plus a SCSI termination device; so a maximum of five internal wide-SCSI hard drives are
supported.

By default, the internal SCSI bus is configured to run in Ultra-SCSI mode (providing a
maximum band-width of 40 MB/s). The user may configure the SCSI system using the
SCSISelect utility, included in the system BIOS. This utility is described in more detail in
the SCSI User’s Guide.

Chapter 2 51

System Board

Devices on the PCI Bus

SCSI-configured-automatically (SCAM) support is provided at level 2, for Plug and Play.
However, hot swap is not supported. The controller is BBS compliant.

The Ultra-wide SCSI controller and cable supports RAIDport PCI devices such as the HP
FastRAID solution (refer to the section “HP FastRAID2” in this chapter).

Integrated Drive Electronics (IDE)

The IDE controller is implemented as part of the PIIX4E chip. It is driven from the PCI
bus, and has PCI-Master capability. It supports Enhanced IDE (EIDE) and Standard IDE
channels. It also supports data rate up to 33 MBytes/second (Ultra DMA 33 mode). To use
the Enhanced IDE features the drives must be compliant with Enhanced IDE.

The IDE controller supports two devices (one master and one slave) connected to a single
channel. The channel is fitted with an IDE cable with two connectors.

It is possible to mix a fast and a slow device, such as a hard disk drive and a a CD-ROM, on
the same channel without affecting the performance of the fast device. The BIOS
automatically determines the fastest configuration that each device supports. However, in
general, the IDE cable is recommended for CD-ROM drives, and the SCSI cables for hard

disk drives.

Universal Serial Bus (USB) Controller

The USB controller is implemented as part of the PIIX4E chip. It is accessed through the
PCI bus, and provides support for the two stacked USB connectors on the back panel
individually. Over-current detection and protection is also provided.

Because the AGP connector defines a USB connection, it is possible to redirect one of the
two USB ports to the AGP connector. In this case, the second external USB port is
disabled. The over-current detection is shared between the second external USB port and
the AGP connector.

USB works only if the USB interface has been enabled within the HP Setup program.
Currently, only the Microsoft Windows 95 and Windows 98 operating systems provide
support for the USB.

The Microsoft Supplement 2.1 software (called USBSupp.exe), which provides support for
the Universal Serial Bus for Windows 95 Software Release (SR) 2.0, can be obtained from
the Hewlett-Packard WorldWideWeb site (refer to the section “AccessHP World Wide Web

Site” in the chapter “System Overview.”

Accelerated Graphics Port (AGP) Controller

Accelerated Graphics Port (AGP) Controller

The AGP technology was developed to provide a dedicated bus for the graphics subsystem,
in order to meet the needs of high quality 3D graphics applications. The HP V
Personal Workstation is equipped with an AGP graphics controller.

The AGP bus is based upon a 66 MHz, 32 Bit PCI bus architecture, to which several signal
groups have been added. These additional signals provide AGP-specific control and
transfer mechanisms:

• Pipelining and sideband addressing. These control mechanisms increase the bus
efficiency in relation to the PCI protocol.

• Double clocking (2x mode). This is a transfer mechanism that doubles the peak transfer
rate to 528 MB/s, as two 32-Bit words are transferred in each clock period (2 x 32 bits x
66 MHz).

AGP specific transactions always use pipelining. The other two mechanisms can combine
independently to pipelining, which leads to the following operating modes:

ISUALIZE

• FRAME based AGP. Only the PCI protocol is used: 66 MHz, 32 Bits, 3.3V, 264 MB/s
peak transfer rate.

• 1 X AGP with pipelining, sideband addressing can be added: 66 MHz, 32 Bits, 3.3V,
increased bus efficiency, 264 MB/s peak transfer rate.

• 2 X AGP with pipelining, sideband addressing can be added: 66 MHz double clocked, 32
Bits, 3.3V, increased bus efficiency, 528 MB/s peak transfer rate.

Devices on the SMBus

The SMBus is a subset of the I2C bus. It is a two-wired serial bus which runs at a
maximum speed of 400 kHz. It is used to monitor some of the hardware functions of the
system board (such as voltage levels, temperature, fan speed, DIMM presence and type),
both at system boot and during normal run-time. It is controlled by the SMBus controller
located in the PIIX4E chip.

• One LM75 temperature sensor.

• MaxiLife for hardware management, bus master controller 400 kHz

• CPUs serial EEPROM - Processor Information ROM (“PIROM”).

• CPUs thermal sensors.

Chapter 2 55

System Board

Devices on the SMBus

An isolation mechanism is implemented, so that the LM75 temperature sensor, MaxiLife
monitoring chip, and the Serial EEPROM can be accessed even when the computer is
turned off. These devices are powered through Vcc standby. The PIIX4E and MaxiLife are
the two master devices.

PIIX4E SMBus Master Controller

The PIIX4E chip provides an intelligent processor-to-SMBus controller. All access is
handled by the processor through the PIIX4E SMBus interface. Typically, the processor

has access to all the devices connected to the SMBus.

DIMM Sockets

Each DIMM socket is connected to the SMBus. The 168-pin DIMM modules used on HP
V

ISUALIZE Personal Workstations include a 256 byte I2C Serial EEPROM. The first 128

bytes contain general information, including the DRAM chips’ manufacturer, DIMM speed
rating, DIMM type, etc. The second 128 bytes of the Serial EEPROM can be used to store
data online. This will be used to store such information as ECC errors and possibly some

manufacturing related data (date module built or first installed, etc).

SDRAM Clock Buffer

The I2C port of the SDRAM clock buffer is connected to the SMBus. It can be used to stop
the unused clocks.

Serial EEPROM

This is the non-volatile memory which holds the default values for the CMOS memory (in
the event of battery failure).

When installing a new system board, the Serial EEPROM will have a blank serial number
field. This will be detected automatically by the BIOS, which will then prompt the user for
the serial number which is printed on the identification label on the back of the PC
Workstation.

The computer uses 16KBytes of Serial EEPROM implemented within two chips. Serial
EEPROM is ROM in which one byte at a time can be returned to its unprogrammed state
by the application of appropriate electrical signals. In effect, it can be made to behave like
very slow, non-volatile RAM. It is used for storing the tatoo string, the serial number, and

the parameter settings for the Setup program and also MaxiLife firmware.

Xeon Thermal Sensors

These sensors are located within the Single Edge Contact (SEC) cartridge. They are used
to measure temperature within the CPU, and this information is used to regulate the CPU
fan speed.

56 Chapter2

System Board

Devices on the SMBus

LM75 Temperature Sensor

The LM75 temperature sensor and alarm are located on the system board. The sensor is
used to measure the temperature in various areas of the system board. This information is
used, with other information, to regulate the hard disk drive fan and to send an alarm to
the processor when the temperature is above maximum and programmed minimum

thresholds.

Main PLL

The registers of the main PLL are accessed through the SMBus. These registers control
the PLL clock signal outputs and are write-only.

WARNING

Writing over the SMBus may be destructive to the PC Workstation as
it allows access to information necessary to the System BIOS,
without which the system will not run.

HP MaxiLife Utility

MaxiLife is a hardware monitoring chip which is resident on the system board. Its
responsibility includes On/Off and reset control, status panel management (Lock button,
LEDs), hardware monitoring (temperature and voltage), early diagnostics (CPU, DIMMs,
PLLs, boot start), run-time diagnostics (CPU errors, package intrusions), and other
miscellaneous functions (such as special OK/FAIL symbols based on a smiling face).

The integrated microprocessor includes a Synopsys cell based on Dallas “8052” equivalent,
a 2 KB boot ROM, 256 bytes of data RAM, an I2C cell, an Analog-to-Digital (ADC) with 5
entries, and an additional glue logic for interrupt control, fan regulation, and a status
panel control.

MaxiLife downloads its code in 96 milliseconds from an I2C serial EEPROM. The total
firmware (MaxiLife 8051-code, running in RAM) size is 8 KB. As it exceeds the 2 KB
program RAM space, a paging mechanism will swap code as it is required, based on a 512
byte buffer. The first 2 KB pages of firmware code is critical because it controls the initial
power on/reset to boot the system. This initial page is checked with a null-checksum test
and the presence of MaxiLife markers (located just below the 2 KB limit).

If the boot block has been corrupted, which prevents the system from powering on, the
Firmware can start from its ‘crisis’ block. To do this, set the System board switch 10 to the
On position. In order to reset the MaxiLife ASIC, unplug the power cord for more than 30
seconds before plugging it back in. Then power on the Personal Workstation and use the
BIOS bootblock recovery feature that is described in the section “BIOS Update Crisis
Recovery Procedure” in this chapter.

MaxiLife is partially replacing HP ASIC (Little Ben), and provides the necessary hardware
monitoring control. However, MaxiLife is not accessible in I/O space or memory space of
the system platform, but only through the SMBUS (which is a sub-set of the I2C bus), via
the PCI/ISA chipset (PIIX4E South Bridge). Its I2C cell may operate either in Slave or
Master mode, switched by firmware, or automatically in the event of ‘Arbitration’ loss.

Chapter 2 57

System Board

Devices on the SMBus

As a monitoring chip, MaxiLife reports critical errors at start-up, and is therefore powered
by Vstandby (3.3V) power. For MaxiLife to work correctly, the Personal Workstation must
always be connected to a grounded outlet. This enables the Personal Workstation’s
hardware monitoring chip to be active, even if the system has been powered off.

Test Sequence and Error Messages

Refer to the section “MaxiLife Test Sequence and Error Messages” in the chapter “Tests
and Error Messages” for detailed information about the different test sequences and error
messages.

MaxiLife Architecture

The MaxiLife chip continuously monitors temperature and voltage sensors located in
critical regions on the system board. This chip receives data about the various system
components via a dedicated I2C bus, which is a reliable communications bus to control the
integrated circuit boards.

The LCD Menu

To access the LCD main menu, press one of the LCD keys. This menu is composed of
several menu items which are displayed two at a time on the LCD screen. The following
menus are available:

• System Info. Obtains information from the BIOS and the system’s Serial EEPROM
from a previously successful boot. This information includes: product name, BIOS
version, serial number, the number of processors and speed, size of memory for each
DIMM socket.
The BIOS logs information in the serial EEPROM with SYSINFO.COM at the end of
the boot.

• Boot Steps. Shows the Power-On Self-Test (POST) codes during the system start-up.
The POST code is provided by the BIOS and is displayed on the LCD panel as soon as it
is available. If the system stops during the
start-up, the last successful boot step POST code is displayed on the LCD.

• Diagnostics. Runs a set of diagnostics assessing the system’s components (CPU
presence, CPU power errors, power supply, clocks, and DIMM presence). To view the

test results for each system component, press button. If no errors are detected, a
screen will display a smiling face. If an error is detected, an error screen appears
indicating the problem.

Using MaxiLife When the Computer Is Powered Off

NOTE

MaxiLife is powered by VSTBY. This means that it is functional as soon as
the power cord is plugged in. For MaxiLife to work correctly, the Personal
Workstation must always be connected to a grounded outlet.

Even if the computer is powered off (the LCD status panel will be blank), MaxiLife is still
running and monitoring the state of the LCD buttons. From this state, the diagnostics
program can be run by pressing one of these buttons. When the Power on option is
selected, the main power supply is started, enabling the hardware monitoring chip to
access the status of the computer’s components. Although the main power supply has been
started, the computer does not continue to complete a normal boot.

The system components are tested in sequence (press the Next button to move on to the
following test). When the diagnostics tests are complete, one of the following screens will
be displayed:

Diagnostics:
Done FAIL

Exit

Diagnostics:
Done OK

Exit

Chapter 2 59

System Board

Devices on the SMBus

If no errors are detected, you can exit the test session, and the main power supply will be
turned off and the LCD status panel will become blank.

If an error is detected, a short message is displayed on the LCD status panel describing the
type of error (memory, processor) that occurred. For example, the message DIMM FOUND: 0
would be displayed if no memory modules could be located. You can then choose whether to
continue viewing the results of the remaining tests.

NOTE

If the Diags program is run when the system is off, it returns to the Off state
when exiting the test session. On/Off transitions are accompanied with a
‘Please wait’ screen to allow MaxiLife to power on and off correctly.

Ultra I/O 2Eh 2Fh

The Super I/O Controller (NS 97317)

The Ultra I/O chip (NS 97317) provides the control for two FDD devices, two serial ports
and one bidirectional multi-mode parallel port.

Serial / parallel communications ports

The 9-pin serial ports (whose pin layouts are depicted in the section “Socket Pin Layouts”
in the chapter “Interface Boards and Mass-Storage Drives”) supports RS-232-C and are
buffered by 16550A UARTs, with 16-Byte FIFOs. They can be programmed as COM1,
COM2, COM3, COM4, or disabled.

The 25-pin parallel port (also depicted in the section “Socket Pin Layouts” in the chapter
“Interface Boards and Mass-Storage Drives”) is Centronics compatible, supporting IEEE

1284. It can be programmed as LPT1, LPT2, or disabled. It can operate in the four

following modes:

• Standard mode (PC/XT, PC/AT, and PS/2 compatible).

• Bidirectional mode (PC/XT, PC/AT, and PS/2 compatible).

• Enhanced mode (enhanced parallel port, EPP, compatible).

• High speed mode (MS/HP extended capabilities port, ECP, compatible).

FDC

The integrated flexible disk controller (FDC) supports any combination of two of the
following: tape drives, 3.5-inch flexible disk drives, 5.25-inch flexible disk drives. It is
software and register-compatible with the 82077AA, and 100% IBM-compatible. It has an
A and B drive-swapping capability and a non-burst DMA option.

RTC

The real-time clock (RTC) is 146818A-compatible, with an accuracy of 20ppm (parts per
million). The configuration RAM is implemented as 256 bytes of CMOS. The RTC operates
on a 32.768 kHz crystal and a separate 3V goldcap that provides up to 3 weeks of
protection when the power cord is unplugged.

The century is stored in a register of the RTC and will automatically change from 1999 to
2000 (without BIOS intervention).

Keyboard and Mouse Controller

The computer has an 8042-based keyboard and mouse controller. The connector pin
layouts are shown in the section “Socket Pin Layouts” in the chapter “Interface Boards and
Mass-Storage Drives.”

Audio Controller

HP VISUALIZE Personal Workstations have an audio chip (AD1816) integrated on the
system board. This single chip is a Plug and Play multimedia audio subsystem for
concurrently processing multiple digital streams of 16-bit stereo audio.

Host Interface

The AD1816 audio chip contains all necessary ISA bus logic on chip. This logic includes
address decoding for all onboard resources, control and signal interpretation, DMA
selection and control logic, IRQ selection and control logic, and all interface configuration
logic.

Audio Chip Specifications

The audio chip is driven from the ISA bus, and has the following specifications:

Flash EEPROM

System Board

The PC Workstation uses 512 KB of Flash EEPROM implemented using two 8-bit ROM
chips. Flash EEPROM is ROM in which the whole memory can be returned to its
unprogrammed state by the application of appropriate electrical signals to its pins. It can
then be reprogrammed with the latest upgrade firmware.

The System ROM contains the LAN boot firmware and the system BIOS (including the
boot code, the ISA and PCI initialization, the Setup program and the Power-On Self-Test
routines, video BIOS, plus their error messages). These are summarized the chapter “HP
BIOS” and the chapter “Tests and Error Messages.”

The Flash EEPROMs on HP V

ISUALIZE Personal Workstations implement a bootblock

feature which allows recovery from a failed attempt at updating the System BIOS. The
bootblock contains the minimum system BIOS information necessary to reprogram the
Flash EEPROM.

Updating the system ROM

The System ROM can be updated with the latest BIOS firmware. This can be downloaded
from HP’s World Wide Web site:

http://www.hp.com/go/visualizesupport

To download a BIOS upgrade, connect to the HP Web site and follow the on-screen
instructions to download the flash utility programs.

Before updating the System ROM, it is necessary to disable the “PSWRD” switch on the
system switches (SW-7), and to type in the System Administrator’s Password when
starting up the computer. The PCI and PnP information is erased in the process.

Do not switch off the computer until the system BIOS update procedure has completed,
successfully or not, otherwise irrecoverable damage to the ROM may be caused. While
updating the flash ROM, the power supply switch and the reset button are disabled to
prevent accidental interruption of the flash programming process.

BIOS Update Crisis Recovery Procedure

If, for example, during a BIOS update process, the process is interrupted by a power
failure, and the system does not start, you can still recover the situation of a destroyed
system BIOS. However, it should be noted that during the recovery procedure, there is no
image on the screen, nor access to the keyboard or mouse (only “vital” devices that are
required to boot on the floppy are initialized). Follow these steps to recover the BIOS:

1. Ensure that you have created a DOS-bootable diskette. This floppy diskette contains all
the recovery and system BIOS programming software (phlash.exe, platform.bin and
HO1xyyzz.Ful). Include the flash command in the first line of autoexec.bat, for example:

phlash /c HO1xyyzz.Ful

H = HP Professional PC
O = HP V

ISUALIZE Personal Workstation (Pentium II Xeon models)

1 = HP Division that provides the platform. In this case, it is PDCO
x = major revision
yy = minor revision
zz = language

NOTE

Setting Switch 10 to the Closed position also enables the MaxiLife firmware
‘crisis’ block if the power cord is unplugged (after approximately 30 seconds).
In this case, the LCD status panel is not available and the screen is blank.

2. Turn off the computer. Set Switch 10 to the Closed position.

3. Insert the DOS-bootable diskette.

4. Turn on the computer.

5. During the recovery process, short beeps are emitted. The recover process is finished
when there is a much longer beep (after approximately 1 to 2 minutes).

6. Power off the computer. Press the power ON/OFF button (for about 5 seconds), until the
ON/OFF light switches off. Set switch 10 to the Up position.

Other ISA Accessory Devices

ISA accessory boards are for slow peripheral accessories. A diagram showing the ISA slots
that are available for the HP V
Board Slots” in this chapter.

Plug and Play

All PCI accessory boards are Plug and Play, although not all ISA boards are. Check the
accessory board’s documentation if you are unsure.

In general, in a Plug and Play configuration, resources for an ISA board have to be
reserved first (using the Setup utility). Then you can plug in your board.

Optional BootROM Socket

It is possible to add a flash device on the network card socket with a specific LAN
BootROM code. This new BootROM code will be seen and mapped automatically by the
system BIOS instead of the embedded version (system BIOS).

NOTE

If you are looking for a specific or a new version of the BootROM, refer to the
LANWORKS web site at: http://www.lanworks.com.

Flash / ROM Devices

The 10BT/100TX card provides a PLCC 32-pin socket, and any size of flash device can be
used up to 256 KB.

Installing Two LAN Remote Power On Cards

From a network standpoint, it is possible to install two LAN RPO cards, and both cards
will be functional (for example, from the operating system, it will be possible to have two
LAN cards up and running at the same time).

However, there are restrictions due to the remote manageability boot features
implementation. To support these features, an internal cable is required between the LAN
card and the system board. However, only one card can be attached to this cable, so that
remote manageability features are supported on one card only.

The problem is that with the current BIOS and hardware implementation, it is not
possible to identify which LAN card the cable is attached to, and this may result in having
none of the remote capabilities working properly.

Even though it is possible to install two LAN Remote PowerOn cards in the computer, only
one card is seen by the BIOS setup. In conclusion, when installing two LAN cards, always
remember that it is very difficult implement the RPO functionality on a LAN card.

NOTE

Administrative tools (for example, TopTool Openview) are not capable of
identifying which network board WOL is connected to.

HP FastRAID2

HP FastRAID2

To improve performance of the 16-bit Wide Ultra SCSI channel, the new generation of HP
FastRAID is available as an option. Both HP V
of supporting the HP FastRAID2 Accessory Kit. When installing HP FastRAID2, please
refer to the Installation and Configuration Guide supplied with the HP FastRAID2
Accessory Kit for instructions.

ISUALIZE Personal Workstationsare capable

WARNING

HP FastRAID2 and HP FASTRAID1 software (BIOS, drivers and HP
Raid device manager) are NOT compatible.

Figure 3-6. HP FastRAID2 Board

The HP FastRAID2 solution (or Accessory Kit if ordered after purchase) includes an
Adaptec ARO2 PCI RAIDport adapter and five disks containing configuration utilities,
drivers and the CI/O Array Management software. Note that the CI/O Array Manager is
also known as the HP RAID Manager, and contains the ArrayConfig utility imbedded in it.
The Accessory Kit, along with the RAIDport connector and firmware on the system board
of the PC Workstation, provide the components necessary to implement FastRAID2.

The ARO2 adapter increases the performance of the PC Workstation’s hard drives by
accelerating data storage and retrieval. Part of this hardware acceleration is due to the
read and write cache options available with the ARO2 adapter. Using the write cache,
when the memory is flushed to the SCSI devices (hard drives), reduces the idle time is to
one tenth of the idle time without the FastRAID2 option. For certain applications, read
caching (i.e. pre-emptive reading and caching of sequential sectors of data, to have ready to
use if needed) can accelerate operations.

Chapter 3 81

Interface Boards and Mass-Storage Drivers

HP FastRAID2

Read/write caching is an advantageous option, but the primary function of the FastRAID2
solution is to provide enhanced hard drive performance through two supported modes:

• Raid0 (default configuration): This configuration provides data read/write acceleration
using one or two hard drives (of the same capacity and speed) through disk striping. In
general terms, data blocks are divided and stored between two hard drives using a
method called disk striping. It is important to point out that there is no redundancy of
data storage, and the RAID 0 mode does not, in any way, reduce the necessity of backing
up stored data.

NOTE

To obtain the benefits of read/write caching using the ARO2 adapter in a
system with only one hard drive, it is necessary to select the RAID0 mode.

• Raid1 configuration: This configuration provides software mirroring and caching. Data
is mirrored (duplicated) using a hard disk pair. If one disk fails, the data is still
available on the mirrored drive. The RAID 1 configuration also provides an
improvement in performance using the cache on the ARO2 adapter. It does not,
however, provide the same throughput as the RAID 0 configuration. In addition,
because data is mirrored, the storage capacity of your drives is only half of the physical
capacity of the drives.

One of the above modes may be selected using the ArrayConfig utility. This utility is
described in detail in the User’s Guide supplied with the Personal Workstation.

The ARO2 adapter and hard drive(s) come pre-configured for maximum performance
(RAID 0) but may also be configured to provide protection against data loss (RAID 1).

CAUTION

Configurations RAID5 and RAID10 are not supported.

The ARO2 adapter is supplied with 16 MB SIMM installed in the adapter memory slot. If
the adapter must be replaced, do not remove the SIMM because the replacement adapter
will be supplied with its own SIMM. In addition, no re-configuration of the FastRAID2 I/O
subsystem is necessary following the replacement of the ARO2 adapter, as all information
concerning the FastRAID2 configuration is stored on the hard disk drive(s).

HP BIOS

HP/Phoenix BIOS Summary

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

Torun the Setup program, press F2 while the initial “Kayak” logo is displayed immediately
after restarting the Personal Workstation.

Alternatively, press
remains on the screen for 20 seconds, but by pressing
indefinitely until

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.

Esc to view the summary configuration screen. By default, this

F5 once, it can be held on the screen

F1 is pressed again.

98 Chapter4

HP BIOS

HP/Phoenix BIOS Summary

Advanced Menu

The Advanced menu does not have the same structure as the Main menu and Power
menu. Instead of presenting a list of fields, it offers a list of sub-menus. The Advanced
menu contains the following sub-menus:

• Processors, Memory and Cache. Configures processor, memory caching, and
processor cache error correction (if supported by the supplied processor).

• Flexible Disk Drives. Enables or disables the on-board flexible disk
controller.

• IDE Devices. Configures IDE devices.

• Internal SCSI 16bits (Adaptec). Enables or disables the 16-bit Adaptec integrated
SCSI interface (refer to the section “Sub-BIOS Systems for SCSI Controllers” in this
chapter).

• Integrated I/O Ports. Enables or disables the on-board parallel and
serial ports at the specified address.

• External and Internal SCSI 16/8-bit (Symbios) Interface. Enables or disables the
integrated SCSI Symbios interface (refer to the section “Sub-BIOS Systems for SCSI
Controllers” in this chapter).

• Integrated Network Interface. Enables or disables the integrated network interface.
This feature must be enabled when an ethernet card is installed.

• Integrated USB Interface. Enable or disable the integrated USB (Universal Serial
Bus) interface. You can also redirect the second USB connection to a special AGP board
(for example, a USB monitor).

• Integrated Audio Interface. Enables or disables the audio interface. This feature is
useful on non plug-and-play operating systems, because the integrated audio chip is
plug-and-play.

• PCI Slot Configuration. Sets the PCI Bus Master bit through the BIOS. This could be
necessary for some older PCI accessory boards.

• ISA Resource Exclusion. Reserves interrupts for legacy ISA devices to prevent
conflict with PCI/PnP devices.

Chapter 4 99

HP BIOS

HP/Phoenix BIOS Summary

Security

Sub-menus are presented for changing the characteristics and values of the System
Administrator Password, User Password, Hardware Protection and Boot Device Security.
The Security Menu contains the following sub-menus:

• User Password. This password can only be set when an administrator password has
been set. The User Password prevents unauthorized use of the computer.

• Administrator Password. This password prevents unauthorized access to the
computer’s configuration. It can also be used to start the computer.

• Hardware Protection. The following devices can have their accesses unlocked/locked:
Integrated Flexible Disk Controller, Integrated IDE Controller, Integrated Data
Communications Ports.

• Boot Devices Security. Selects whether the computer can be started over the
network. It also selects which devices are to be used for booting up the system. The
option Disabled prevents unauthorized use of a device to start the computer.

Boot Menu

Select the order of the devices from which you want the BIOS to attempt 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 Boot Device Priority list until an operating system is
found.

The QuickBoot Mode option allows the system to skip certain tests while booting. This
decreases the time needed to boot the system.

Power Menu

This menu allows you to set the standby delay. It also allows the system administrator to
decide whether the mouse is enabled as a means of reactivating the system from Standby.
It is also possible to specify whether the space-bar is enabled as a means of reactivating
the system from Off.
