^1.Note that even though the desktop power supply is autoselect, it is not a full range power supply.

It works in 2 input voltage range and not in one big 90 V to 240 V range.

^2.On minitower models, always check the voltage switch position at first power-on.

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 PC

Workstations), will cause the overload protection in the power supply to be

triggered, and the PC Workstation could fail to boot.

Both power supplied on the desktop and minitower models are new

compare to the ones used on previous platforms (Vectra VL 6/xxx and XA 6/

xxx). The difference is at the V standby level, which has been extended to

deliver 300mA instead of 100mA. This extra current is required by the

100TX hardware layer so it can perform a remote power-on at reception of a

magic frame. Using an older power supply for a repair will prevent a remote

power-on at reception of a magic frame.

NOTE

When the PC Workstation is turned off with the power button on the front

panel, the power consumption falls below 5 Watts, but is not zero. The special

on/off method used by this PC Workstation extends the lifetime of the power

supply. To reach zero power consumption in “off” mode, either unplug the PC

Workstation from the power outlet or use a power block with a switch. You

should be aware that the PC Workstation will lose its time settings within a

few days if you unplug the PC, or switch off the PC Workstation at the power

block.

Operating temperature and humidity ranges may vary depending upon the

mass storage devices installed. High humidity levels can cause improper

operation of disk drives. Low humidity levels can aggravate static electricity

problems and cause excessive wear of the disk surface.

2 System Board

Chip-Set

The Intel AGPset is comprised of two chips. The 440LX PAC chip and the

PIIX4chip.

• The PAC chip (440LX) is the bridge between four buses: the PL (GTL)

bus, the main memory bus, the PCI bus and the AGP (graphic) bus.

• The PIIX4 chip is the bridge between three buses: the PCI bus, the SM bus

and the ISA bus. In addition, it contains the IDE controller, USB

controller and Power Management logic

The PAC Chip (440LX)

The PAC chip, called the Intel 440LX AGPset, is contained in a Ball Grid

Array (BGA) package, giving a smaller footprint and higher reliability.

The PAC chip integrates a Host-to-PCI bridge, optimized DRAM controller

and data path, and an Accelerated Graphics Port (AGP) interface. The AGP

is a high performance, component level interconnect, targeted at 3D

graphics applications.

PL Bus Interface

PCI Bus Interface

The PAC chip monitors each cycle that is initiated by the processor, and

forwards those to the PCI bus that are not targeted at the local memory. It

translates PL bus cycles into PCI bus cycles.

The chip can support one or two Pentium II processors, at up to 66 MHz FSB

clock frequency. Refer to page 35 for a description of the devices on the

Processor-Local Bus.

The PCI bus interface is PCI 2.1 compliant.

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.

The PCI arbiter supports PCI bus arbitration for up to six masters using a

rotating priority mechanism. Its hidden arbitration scheme minimizes

arbitration overhead. Additional logic on the PC Workstation extends the

number of fully supported masters to seven (440LX master not counted).

Refer to page 39 for a description of the devices on the Processor-Local Bus.

2 System Board

Chip-Set

AGP Bus Interface

A controller for the AGP (Accelerated Graphics Port) slot is integrated in the

440LX PAC chip. The PAC chip supports only a synchronous AGP interface,

coupling to the host bus frequency. The AGP characteristics are described in

detail in “Accelerated Graphics Port (AGP) Controller” on page 41.

Main Memory Controller The main memory controller supports three DIMM slots. Each slot can host

a 168-pin unbuffered SDRAM module, running at 66MHz, for a total of up to

348 MB of dynamic random access memory (ECC SDRAM).

The memory bus is 72-bits wide, comprised of 64 bits of data and 8 bits of

ECC. Refer to “Main Memory Bus” on page 38, for more detail on the main

memory.

Read/Write Buffers

System Clocking

The PAC chip 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).

The PAC chip operates the host interface at 66MHz, PCI at 33 MHz and AGP

at 66/133 MHz. Coupling between all interfaces and internal logic is done in a

synchronous manner. The PAC chip is not designed to support host bus

frequencies lower than 66 MHz. The clocking scheme uses an external clock

synthesizer (which produces reference clocks for the host, AGP and PCI

interfaces).

2 System Board

Chip-Set

The PIIX4, PCI/ISA Bridge Chip (82371AB)

The universal host controller interface (UHCI) chip, known as PIIX4, is

encapsulated in a Ball Grid Array (BGA) package.

The PIIX4 chip is a multi-function PCI device implementing a PCI-to-ISA

bridge function, a PCI IDE function, a Universal Bus host/hub function, and

an Enhanced Power Management function.

The following figure shows an example of the system block diagram using

the PIIX4 chip.

PCI Bus Interface

ISA Bus Interface

This part of the chip is responsible for transferring data between the PCI bus

and the ISA expansion bus. It performs PCI-to-ISA, and ISA-to-PCI bus cycle

translation. It supports the Plug-and-Play mechanism. Data buffers are

provided, to isolate the PCI and ISA buses. Refer to page 39 for a description

of the devices on the PCI Bus.

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. It can

directly support six ISA slots without external data or address buffering.

Refer to page 45 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

PIIX4 controller. It runs at a maximum of 16 kHz. The bus monitors some of

the hardware functions of the main board, both during boot-up and run-time.

All accesses to the SM bus are handled by the main processor, via the PIIX4

SM bus registers. Refer to page 43 for a description of the devices on the SM

(System Management) Bus.

IDE Controller

USB Controller

The PCI master/slave IDE controller, supporting four devices, two on each of

two channels, is described on page 39.

The PCI USB (Universal Serial Bus) controller, supports two stacked USB

connectors on the back panel. These ports are built into the PIIX4

controller, as standard USB ports. The USB is described in detail on page 40.

Ultra 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 page 82). 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

The interrupt controller incorporates the functionality of two 82C59

interrupt controllers. The two controllers are cascaded, supporting 15

interrupts (edge/level triggered). A table on page 83 shows how the master

2 System Board

Chip-Set

and slave controllers are connected.

Counter / Timer

Serial EEPROM

The chip contains a three-channel 82C54 counter/timer. The counters use a

division of the 14.318 MHz OSC input as the clock source.

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 on page 43.

Cache Memory

There are two integrated circuits sealed within a single Pentium II package.

One of these contains the Level-2 (L2) cache memory chip; the other

contains the processor, which itself includes two banks of Level-1 (L1)

cache memory.

The L1 cache memory has a total capacity of 32KB (16 KB data, 16 KB

instruction). The L2 cache memory has a capacity 512 KB, 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 for each transaction.

The amount of cache memory is set by Intel at the time of manufacture, so

cannot be changed.

2 System Board

Devices on the Processor-Local Bus

The Processor-Local (PL) bus of the Pentium II processors, also referred to

as their FSB (Front Side Bus), is implemented in the GTL+ technology. This

technology features open-drain signal drivers that are pulled-up to 1.5 V

through 56 ohm resistors on both ends of the bus; these resistors also act as

bus terminators, and are integrated in the Pentium II processors.

The supported operating frequencies of the GTL+ bus are 60 MHz and

66 MHz. The width of the data bus is 64 bits, the width of the address is 32

bits.

The control signals of the PL bus allows the implementation of a “split -

transaction” bus protocol. This allows the Pentium II processor to send its

request (such as asking for the contents of a given memory address) and

then to release the bus, rather than waiting for the result, thereby allowing

to accept another request. The 440LX 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.

Intel Pentium II Microprocessor

The Pentium II processor has several high-performance features that

enhance performance:

• Dual Independent Bus architecture, which combines a dedicated 64-bit

L2 cache bus (supporting level cache sizes of 256K or 512K), plus a 64-bit

system bus with ECC that enables multiple simultaneous transactions (re-

fer to above “split -transaction”).

• Intel MMX technology, which gives higher performance for media, com-

munications and 3D applications.

• Dynamic execution to speed up software performance.

The Pentium II processor and level-2 cache memory are packaged in a self-

contained, pre-sealed module, installed in a socket on the system board.

2 System Board

Devices on the Processor-Local Bus

The heat-sink is supplied with the processor, and is bolted to it by the

manufacturer. The module is held in place by a bracket. There are two

plastic clips, one on the top of each pillar of the bracket, to hold the

processor module in place.

To remove the old processor module:

1 Press the two plastic clips towards each other.

2 Carefully pull the processor module away from its connector on the

system board.

Only upgrades, pin compatible with the original processor, manufactured by

Intel, are supported.

Bus Frequencies

There is a 14.318 MHz crystal oscillator on the system board. This frequency

is multiplied to 66 MHz by a phase locked loop. This is further scaled by an

internal clock multiplier within the processor.

For example, the Pentium II 300 MHz processor multiplies the 66 MHz

system clock by 4.5. Switches 1 and 2, on the system board switches, set the

frequency of the Processor-Local bus, which for all HP Kayak XA PC

Workstation models, is 66 MHz. Switches 3, 4 and 5 set the clock multiplier

ratio.

^1.Processor bus frequency is always set at 66MHz for all XA PC Workstations models.

^2.Switches are provided to match the system board to processor frequency when a

system board repair is performed.

The computer may execute erratically, if at all, or may overheat, 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.

Setting the switches to operate at a slower speed, than the processor is

capable of supporting, can still cause erratic behavior in some cases, and

would reduce the instruction throughput in others.

2 System Board

Main Memory Bus

The memory bus is 72-bits wide, comprised of 64 bits of data and 8 bits of

ECC. It is connected to the Main Memory and to the PAC (440LX) chip.

There are three 168-pin DIMM slots on the system board for installing main

memory; slots A, B and C. All HP Kayak XA PC Workstation models are

supplied with one memory module (either 16 MB, 32 MB or 64 MB ECC

SDRAM) in one of the three slots, leaving the other slots free for memory

upgrades.

The slots can be filled in any order, but there is a performance advantage in

filling the slots in the order A, B, C. Memory upgrades are available in single

32 MB, 64 MB or 128 MB ECC SDRAM modules. Note that replacement of

the supplied memory module may be necessary to obtain the 384 MB

maximum memory, unless the supplied module was 128 MB.

With non-ECC SDRAM memory modules, a maximum of 192 MB can be

obtained. These memory modules can be either; 16 MB, 32 MB or 64 MB.

NOTE

If ECC and non-ECC memory modules are both installed, ECC will be

invalidated for all memory modules.

Error Correcting Code

Operation

The error correcting code (ECC) memory of the HP Kayak XA PC

Workstation 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 PAC 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).

Integrated Drive Electronics (IDE)

The IDE controller is implemented as part of the PIIX4 chip (the PCI/ISA

bridge). It is driven from the PCI bus, and has PCI-Master capability. It

supports Enhanced IDE (EIDE) and Standard IDE. 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.

2 System Board

Devices on the PCI Bus

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 determines automatically, 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 PIIX4 chip. It is accessed

through the PCI bus, and provides support for the two stacked USB

connectors on the back panel. Over-current detection and protection is

provided, but shared between the two ports.

USB works only if the USB interface has been enabled within the HP Setup

program. Currently, only the Microsoft Windows 95 and Windows NT

operating systems provides support for the USB.

The Microsoft Supplement 2.1 software called (called USBSupp.exe), which

provides support of the Universal Serial Bus, can be obtained from the

Hewlett-Packard World Wide Web site (refer to “Access HP World Wide

Web” on page 21).

Other PCI Accessory Devices

PCI accessory boards are for high-speed peripheral accessories. A network

board could already occupy one of the PCI slots. A diagram showing the PCI

slots that are available for the desktop and minitower models is on page 27.

Plug and Play

The HP Kayak XA/ PC Workstations have a “PnP level 1.0A” BIOS and

meets the “Windows 95 Required” level for Plug and Play. Accessory boards

which are Plug and Play are automatically configured by the BIOS.

2 System Board

Accelerated Graphics Port (AGP) Controller

The AGP technology was developed as a means to access system memory as

a viable alternative to augmenting the memory of the graphics subsystem

needed for high quality 3D graphics applications. All models of HP Kayak

XA PC Workstations support an AGP (Accelerated Graphics Port) device

(Laguna Graphic Controller from Cirrus).

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 allow to

implement AGP specific control and transfer mechanisms, which are:

• Pipelining and sideband addressing. These control mechanisms in-

crease the bus efficiency compared 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 these operating

modes:

• 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 dou-

ble clocked, 32 Bits, 3.3V, increased bus efficiency, 528 MB/s peak trans-

fer rate.

PLL

The System Management (SM) bus is used to monitor several of the

hardware functions (such as voltage levels, temperature, fan speed, DIMM

presence and type) of the system board. It is controlled by the SM bus

controller located in the PIIX4 chip.

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 4 Kbit of Serial EEPROM implemented within a single

512 K ✕ 8-bit ROM chip. 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.

2 System Board

Devices on the SM Bus

LM75 Chip

The LM75 chip is a temperature sensor and alarm located on the system

board. It is used to measure the temperature in one area of the PC

Workstation, and to send an alarm to the processor in case of overheating.

This chip includes a security mechanism which prevents the system fan

from being disabled using software controls so long as the temperature

measured by the sensor is above the maximum operating temperature.

Main PLL

The registers of the main PLL are accessed through the SM bus. These

registers control the PLL clock signal outputs and are write-only.

WARNING:

Writing over the SM bus may be destructive to the PC Workstation, as it

allows to access information necessary to the System BIOS, without which

the system will not run.

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 onboards resources, control and signal

interpretation, DMA selection and control logic, IRQ selection and control

logic, and all interface configuration logic.

Audio Chip

It is driven from the ISA bus, and has the following specification:

Flash EEPROM

The PC Workstation uses 256 KB of Flash EEPROM implemented using one

8-bit ROM chip. 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 in Chapters 4 and 5.

The Flash EEPROMs on the HP Kayak XA PC Workstation 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.

System Board Switches

The first two of the system board switches set the frequency of the

Processor-Local bus, and the next three the ratio of processor-frequency to

Processor-Local-bus-frequency, as summarized on page 37.

The next five switches set the configuration for the PC Workstation, as

summarized in the table below.

BIOS Update Crisis

Recovery Procedure

If, for example, during a BIOS update process, the procedure is interrupted

by a power failure, and the system does not start, then 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 dis-

kette contains all the recovery and system BIOS programming software

(phlash.exe, platform.bin and hblxxxyy.Ful). Include the flash command

in the autoexec.bat, for example: phlash /mode=3 HC1xyyzz.Ful

H = HP Professional PC

C = Kayak XA (Pentium II models)

1 = Kayak family

x = major revision

yy = minor revision

zz = language

2 Turn off the computer. Set Switch 9 to the Closed position.

3 Insert the DOS-bootable diskette.

2 System Board

Devices on the ISA Bus

4 Power 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 the switch 9 to the

Open position.

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/kayaksupport

To download a BIOS upgrade, connect to the HP Web site and follow the on-

screen instructions to download the flash utility programs (FLASH.BAT,

AUTOEXEC.BATand PHLASH.EXE), the BIOS file (HC11xx.FUL), and a file

called pfmhd106.bin, onto a bootable diskette.

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.

Little Ben

Little Ben is an HP application specific integrated circuit (ASIC), designed

to be a companion to the Ultra I/O chip, that is connected between the chip-

set and the processor. It contains the following:

• BIOS timer

❒ hardware wired 50 ms long 880 Hz beep module.

❒ automatic blinker that feeds the LEDs module with a 1 Hz oscillator

signal.

• Security protection (access, flash and anti-virus protection)

❒ For 128, 256 or 512 KB Flash EEPROMs.

2 System Board

Devices on the ISA Bus

❒ For the Ultra I/O space: the Serial EEPROM, serial port, parallel port

and mass storage drives (disable write on Flexible Disk Drive, disable

boot on any drive, disable use of any embedded drive)

• Advanced Power Management (APM) version 1.2

• Glue logic (such as programmable chip selects)

When the user requests a ShutDown from the operating system, the

environment is first cleared. Any request to turn off the PC Workstation,

from the control panel, or from the operating system, can only be granted if

the PC Workstation is not locked by Little Ben’s lock bit (otherwise the

power remains on, a red light is illuminated, and the buzzer is sounded).

Other ISA Accessory Devices

ISA accessory boards are for slow peripheral accessories. A diagram

showing the ISA slots that are available for the desktop and minitower

models is on page 27.

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) and then you can plug in your

board.

The procedure for installing an ISA accessory board that is not Plug and

Play is described in the User’s Guide that is supplied with the PC

Workstation.

NOTE

The Windows NT 4.0 operating system is not Plug and Play. Information

explained above is only applicable for Plug and Play operating systems (for

example, Windows 95).

Cirrus 5465 Graphics Controller Chip

Connectors

The Video Electronics Standards Association (VESA) defines a standard

video connector, variously known as the VESA feature connector,

auxiliary connector, or pass-through connector. The graphics controller

supports an input/output VESA feature connector. This connector (whose

pin names are listed in a table on page 71) is integrated on the system board,

and is connected directly to the pixel data bus and the synchronization

signals.

Video Memory

The HP Kayak Workstation PCs are supplied with 4 MB of video memory

integrated on the system board (revision B). There is either, an on-board

4 MB video memory soldered onto the system board. Or, 2 MB of built-in

video memory (revision A) and a 2 MB video memory module installed in

the video memory upgrade socket, giving 4 MB in total.

The video RAM (also known as the frame buffer) is a local block of 50 ns

EDO DRAM for holding both the on-screen surface (reflecting what is

currently displayed on the screen), and the off-screen surface (video frame,

fonts, double buffer).

The following diagrams show the position of the video memory module on

the minitower and desktop computers.

The soldered video memory (revision B) is located in the same area on the

system board as the video memory module.

Available Video Resolutions

The number of colors supported is limited by the graphics device and the

video memory. The resolution/color/refresh-rate combination is limited by a

combination of the display driver, the graphics device, and the video

memory. If the resolution/refresh-rate combination is set higher than the

display can support, you risk damaging the display.

SCSI / LAN Combo Board

Certain HP Kayak XA PC Workstations are supplied with an integrated

SCSI / 10BT/100TX LAN combo board. Because the SCSI / LAN combo

board includes two controllers, only one PCI slot is necessary for installing

this board. The PCI and SCSI controllers access the PCI bus through a PCI

bridge. The SCSI and PCI functionalities of the SYM8751SP are contained

within the Symbios Logic SYM5C875J PCI-SCSI I/O Processor chip.

10BT/100TX LAN Controller

Certain models of the HP Kayak XA PC Workstation are supplied only with

a 10BT/100TX LAN adapter which supports the following standards:

100 Mbits per second over 2-pair, category-5, unshielded twisted pair

(UTP), or shielded twisted pair (STP); 10 BaseT, 10 Mbits per second, ISO

8802-3 (IEEE 802.3 standard).

On the rear panel there is one RJ-45 connector. There is an LED which

indicates the LAN connection status as follows:

• Off - when there is no Autonegotiation response (for example, when the

LAN cable is not connected to the network HUB.

• Blinking - during Autonegotiation

• Green (ON) - the connection has passed the Autonegotiation and a link

has been established between the LAN adapter and the network HUB/

Switch.

The LAN adapter contains a connector to which an internal LAN cable may

be connected to the external start connector on the system board, necessary

for the use of the Remote Power On feature, described in detail in the User’s

Guide provided with the PC Workstation. The LAN adapter that uses the

Remote Power On feature must be installed nearer the processors than any

other supplementary LAN adapter card.

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

At the time this TRM was produced, there was no flashing tool available to

allow you to update the bootrom content in the flash on the LAN adapter. A

flashing tool for any AMD based card may be available, but in order to use this

tool on HP cards, only 29fxxx flash devices must be used. At present, no test

has been carried out using this tool on HP cards.

Installing Two LAN

Remote Power On Cards

From a pure network standpoint, this is supported 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. Only one card can be

attached to this cable, therefore remote manageability features are

supported only on one card.

The problem is that current BIOS and hardware implementation doesn’t

allow to identify to which card the cable is attached and this may result in

having none of the remote capabilities working properly. Also, remote boot

can only work on one card.

Therefore, if a customer wants to use two HP LAN cards without using HP

LAN enhanced features (Remote boot, Remote power on), then there is no

problem. However, if there is a requirement to use the HP LAN enhanced

features, then it is not possible, at the present time, to use the two LAN

cards on one system.

Even though it is possible to install two LAN Remote Power On cards in the

computer, only one card is seen by the operating system.

HP BIOS

The Setup program and BIOS are summarized in the two sections of this

chapter. The POST routines are described in the next chapter.

4 HP BIOS

HP/Phoenix BIOS Summary

The System ROM contains the POST (power-on self-test) routines, and the

BIOS: the System BIOS, video BIOS (for models with an integrated video

controller), and low option ROM. This chapter, and 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 HC.11.xx. The

procedure for updating the System ROM firmware is described on page 50.

Using the HP Setup Program

Press

, to run the Setup program, while the initial “Kayak” logo is being

displayed immediately after restarting the PC.

Alternatively, press

to view the summary configuration screen. By

default, this remains on the screen for 20 seconds, but by pressing

once,

it can be held on the screen indefinitely until

will cause the computer to be turned off.

is pressed again. Pressing

The band along the top of the Setup screen offers five 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 PC Workstation.

Main Menu

The Main Menu presents a list of fields, such as “System Time” and “Key

Click”.

4 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:

• Memory and Cache. Define how to configure the specified block of

memory.

• Video. Set the best ergonomic refresh rate supported by the display. This

feature, can also be used to set the preferred refresh rate for each graphic

mode.

• Flexible Disk Drives. Enable or disable the on-board flexible disk

controller.

• IDE Devices. Configure IDE Primary and Secondary devices.

• SCSI Interface. Enable or disable the integrated SCSI interface. In the

Ultra SCSI item, the Auto option will enable or disable automatically the

Ultra SCSI by the BIOS, depending on whether external SCSI devices are

detected or not.

• Integrated Network Interface. Enable or disable the integrated network

interface. This feature must be enabled when an ethernet card is installed.

• Integrated Peripherals. Enable or disable the on-board parallel and

serial ports at the specified address.

• Integrated USB Interface. Enable or disable the integrated USB

(Universal Serial Bus) interface.

• Integrated Audio Interface. Enable or disable the audio interface. This

feature is useful on non plug-and-play operating systems, because the

integrated audio chip is plug-and-play.

• PCI Devices. Enable this option if you need the BIOS to set the PCI Bus

Master bit. 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.

4 HP BIOS

HP/Phoenix BIOS Summary

Security

Sub-menus are presented for changing the characteristic and values of the

System Administrator Password, User Password, Hardware Protection and

Boot Device Security, the amount of protection against the system’s drives

and network connections, and the amount of protection against being able

to boot from the system’s drives and network connections. 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, protects stored data.

• 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 ICD

Controller, Integrated Data Communications Ports and Integrated

Interfaces.

• Boot Device Security. Select 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 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 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.

Symbios Logic SCSI Configuration Utility

The Symbios Logic SCSI Configuration Utility lets you view and change the

default configuration for the host adapter and all SCSI devices connected to

it, or for individual SCSI devices. If, while using this utility, you accidentally

disable all the controllers, pressing

during the power-on self test (after

the memory test) lets you recover and configure settings.

Default Settings You Can Change

The following two tables show the configuration settings that can be

changed. The first table shows the global settings which impact the host

Power-On from Space-Bar

The power-on from the space-bar function is enabled, provided that:

• The computer is connected to a Power-On keyboard (recognizable by the

Power-On icon on the space bar).

• The computer is running a Windows operating system.

• The function has not been disabled by setting SW-8 to open on the system

board switches.

• The function has not been disabled in the “Power” menu of the Setup

program.

Soft Power Down

When the user requests the operating system to shutdown, the environment

is cleared, and the computer is powered off. Soft Power Down is available

with the Windows NT and Windows 95 operating systems.

The hardware to do this is contained within the PIIX4. This chip is described

on page 50.

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.

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, optional system performance is reached when minimizing the

sharing of interrupts. Refer to pages 27 and 28 for the Desktop and Mini-

tower Backplane PCI Mapping tables, and page 39 for a table of the PCI

device interrupts.

Power-On Self-Test and Error Messages

This chapter describes the Power-On Self-Test (POST) routines, which are

contained in the computer’s ROM BIOS, the error messages which can

result, and the suggestions for corrective action.

5 Power-On Self-Test and Error Messages

Order in Which the 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 HP PC Workstation’s

logo when the PC is restarted. If you wish to view the POST details, press

to get the HP Summary Screen.

If the POST detects an error, the error message is displayed inside a view

system errors screen, in which the error message utility (EMU) not only

displays the error diagnosis, but the suggestions for corrective action (see

page 93for a brief summary). Error codes are no longer displayed.

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.

An example of an Error This example explains the different coding messages that appear in the lower

left corner of the screen when the POST detects an error during startup.

Code Message

For example, if the error 0101 - 52 is displayed.

• 0101 - Post Error Code failure. This error code is accompanied by short

message. For this example, the message “keyboard error” is displayed.

A table listing the error codes, causes and symptoms is on page 94.

• 52 - Post Checkpoint Code. This checkpoint code indicates that a test has

failed at this stage of the POST.

A table listing the error codes, causes and symptoms is on page 87.

5 Power-On Self-Test and Error Messages

Error Message Summary

The EMU utility (.COM application written in C language) is to provide full

screen online help messages (localized) on most common POST errors.

When an error is generated in POST during the boot process, EMU is run by

typing ENTER. The entry point of each EMU message is a 4-digits error

code generated by POST.

If the POST reports an error, one of the following four error categories will

be displayed.

Category #1: if the error requires to run Setup, the POST should prompt:

<F1= Continue>, <F2= Setup>, <Enter= View System Error>

and pause. (refer to autoconfig specification for more details on POST prompts)

Category #2: if the error is only a warning (i.e. key stuck), the POST should prompt:

<Enter= View System Error>

for 2 seconds then boot. (refer to autoconfig specification for more details on POST prompts)

Category #3: if the error is because a device has been unplugged or removed, the POST should prompt :

“If errors are reported because one or more of the listed components have been removed,

press <F4> to validate the changes.”

<F1= Continue>, <F2= Setup>, <F4= Validate Change>, <Enter= View System

Error>

and pause. (refer to autoconfig specification for more details on POST prompts)

Category #4: if the error is serious, the POST should prompt:

The BIOS has detected a serious problem that prevents your PC from booting.”

<F2= Setup>, <Enter= View System Error>

and stop. Only the setup and the EMU can be run. The BIOS must never boot on HDD.

Message

Explanation or Suggestions for Corrective Action

Operating system not found

Check whether the disk, HDD, FDD or CD-ROM disk drive is

connected.

If it is connected, check that it is detected by POST.

Check that your boot device is enabled on the Setup Security

menu.

If the problem persists, check that the boot device contains the

operating system.

Missing operating system

If you have configured HDD user parameters, check that they are

correct. Otherwise, use HDD type “Auto” parameters.

Resource Allocation Conflict -PCI

device 0079 on system board

Clear CMOS.

Video Plug and Play interrupted or

You may have powered your computer Off/On too quickly and the

failed. Re-enable in Setup and try again computer turned off Video plug and play as a protection.

System CMOS checksum bad - run

Setup

CMOS contents have changed between 2 power-on sessions. Run

Setup for configuration.

No message, system “hangs”

Check that cache memory and main memory are correctly set in

their sockets.

Other

An error message may be displayed and the computer may “hang”

for 20 seconds and then beep. The POST is probably checking for a

mass storage device which it cannot find and the computer is in

Time-out Mode. After Time-out, run Setup to check the

configuration.

Beep Codes

If a terminal error occurs during POST, the system issues a beep code before

attempting to display the error in the upper left corner of the screen. Beep

codes are useful for identifying the error when the system is unable to

display the error message.

This does not indicate an error. There is one short beep

before system startup.

^1.If the BIOS detects error 2C or 2E (base 512K RAM error), it displays

an additional word-bitmap (xxxx) indicating the address line or bits that

failed. For example, “2C 0002” means address line 1 (bit one set) has

failed. “2E 1020” means data bits 12 and 5 (bits 12 and 5 set) have failed

in the lower 16 bits.

5 Power-On Self-Test and Error Messages

Lights on the Hardware Control Panel

When the computer is first powered on, the power-on light on the status

panel illuminates yellow for about a second before changing to green. This

change of color is caused by the execution of an instruction early in the

System BIOS code.

If the light remains at yellow, therefore, it indicates a failure of the processor

or the System ROM in the instruction-fetch process. Check that the

processor is correctly seated in its socket, and that the memory DIMMS and

accessory cards are properly installed.

NOTE

An 8 x 14 font for the EGA modes can be provided with a DOS TSR

(terminate and stay resident) program. If the TSR has not been loaded when

the mode is set, the 8 x 16 font is used with the two bottom rows deleted. This

causes truncation of characters with descenders, but does not restrict

program operation. The TSR should be used for absolute compatibility with

DOS applications that use the 8 x 14 font.

NOTE

An 8 x 14 font for mode 55h is provided with a DOS TSR (terminate and stay

resident) program. If the TSR has not been loaded when the mode is set, the

8 x 16 font is used with the two bottom rows deleted. This causes truncation

of characters with descenders, but does not restrict program operation nor

does it make characters particularly difficult to read. For absolute

compatibility with some DOS applications that use the 8 x 14 font, the TSR

should be used.

It should also be noted, that some modes are not supported by all monitors.

The fastest refresh rate for that particular monitor type selected is

automatically used.
