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.

2 System Board  
Chip-Set  
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.  
30  
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).  
31  
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

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  
33  
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.  
34  
2 System Board  
Devices on the Processor-Local Bus  
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.  
35  
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.  
37  
2 System Board  
Main Memory Bus  
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.  
39  
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.

Accelerated Graphics Port (AGP) Controller  
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.

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.

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.

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.  
49  
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

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

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

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

plus a SCSI termination device; so a maximum of 4 internal wide-SCSI hard  
drives are supported.

SCSI / LAN Combo Board  
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 SCSI Configuration Utility, included in the system  
BIOS. This utility is described in more detail on page 77.  
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.  
External (8-bit) SCSI  
connector  
The Ultra narrow 8-bit SCSI connector uses addresses ranging from 0 to 7. As  
with the 16-bit internal SCSI connector, the SCSI address 0 is used by the first  
SCSI hard disk drive and SCSI address 7 is reserved for the integrated SCSI  
controller (the default for wide and narrow SCSI devices).

10BT/100TX LAN Controller  
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.

NOTE  
Refer to the User’s Guide for details concerning system configuration

Remote Power On  
Remote Power On (RPO) is available at 10 and 100 Mbits per second.  
Vstandby requirements The Vstandby requirements for HP network cards supporting RPO, is:  
supporting RPO  
• A power supply able to deliver at least 250mA on Vstandby output. This is  
the case for all HP Kayak systems.  
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.  
Flash / ROM Devices  
The 10BT/100TX card provides a PLCC 32-pin socket and any size of flash  
device can be used up to 256KB§.

10BT/100TX LAN Controller  
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/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 (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.

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.

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.  
85  
5 Power-On Self-Test and Error Messages  
Order in Which the Tests are Performed  
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  
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

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  
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.

Lights on the Hardware Control Panel  
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.

1.Interlaced mode.  
2.Higher refresh modes available with generic fix-up TSR.  
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.

1.16M colors, but with 32-bit-per-pixel format.  
2.+A indicates 16M colors + Alpha Channel  
3.Interlaced mode.  
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.
