Product Features
Product Features
Processor-Local Bus Devices
• Intel PentiumTM II microprocessor (single or dual)
• Intel 440LX AGPsetTM
Intel Pentium II
microprocessor
Single or dual Pentium II processors are used in all models. Both the
microprocessor and 512 KB of Level II cache memory are contained within
the single integrated circuit package. Dual processor upgrade kits include the
Pentium II processor, heat sink and VRM.
AGP Graphics
Subsystem
Matrox Millennium II AGP graphics controllers are standard for all models
(refer to page 12 for details). The AGP is an extension of the DIB (Dual
Interface Bus) Pentium II processor architecture.
PCI Bus Devices
• Ultra SCSI I/O subsystem
• HP FastRAID Accessory Kit (some models)
Ultra SCSI I/O
Subsystem
Based on two separate Adaptec® SCSI controllers:
• 16-bit Wide Ultra SCSI controller, based on the Adaptec® AIC7880 chip,
provides transfer rates of up to 40 MB/s, and is entirely dedicated to inter-
nal hard disks.
• 8-bit Narrow Ultra SCSI controller, based on the Adaptec® AIC7860 chip,
provides transfer rates of up to 20 MB/s, and is used to control other in-
ternal and external devices.
SCSI accessories can be configured using the SCSISelectTM utility,
accessible by pressing during POST. The following features may be
configured:
• SCSI boot device configuration
• SCSI device configuration (assigning of device IDs to SCSI accessories)
• Array 1000 BIOS (only available with HP FastRAID Accessory Kit)

Product Features
HP FastRAID
Accessory Kit
To enhance the performance of the 16-bit Wide Ultra SCSI channel, HP
FastRAID has been introduced as an option. HP FastRAID increases data
read/write speeds to the hard disk drives by read/write caching and disk
striping. Models with the HP FastRAID Accessory Kit have an Adaptec®
ARO-1130 PCI RAIDport adapter installed in the RAIDport connector slot.
The ARO-1130 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 reconfiguration of the FastRAID I/O subsystem is necessary
following the replacement of the ARO-1130 adapter, as all information
concerning the FastRAID configuration is stored on the hard disk drive(s).
Please refer to page 9 for information concerning the FastRAID
configuration when adding or replacing hard disk drives.
The ARO-1130 adapter and hard drive(s) come preconfigured for maximum
performance (RAID 0) but may also be configured to provide protection
against data loss (RAID 1).
The RAID 1 configuration provides software mirroring and caching. Data is
mirrored (duplicated) using a 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 ARO-1130 adapter. It
does not, however, provide the same level of throughput as the RAID 0
(default) configuration. Also, because data is mirrored, the storage capacity
of the hard drives is only half the physical capacity of the drives.
All HP Kayak XU PC Workstation models contain the FastRAID port, and
so allow for post-purchase installation of the HP FastRAID Accessory Kit. It
should be noted that use of the ARO-1130 adapter with a single drive will
still increase performance due to the read/write caching feature built into
the ARO-1130 adapter.

Product Features
Other Features
• HP TopTools
• DiagTOOLS
• Ultra-Flow Cooling System
HP TopTools Pressing the HP TopTOOLS soft key on the HP enhanced keyboard opens the
utility. HP TopTOOLS allows remote management of each client PC, in the
following areas: asset inventory (model numbers, hard disk type, CPU etc.),
remote exploring and configuration of the client PC, remote BIOS update and
hardware monitoring (failure prediction, POST errors, temperature, voltage,
etc.) with remote alerting.
Monitoring of voltage and temperature of devices on the system board is
performed by two chips on the SM Bus. The LM78 chip controls voltage for
the processor(s) and monitors temperature via two sensors (at the hard
drives and on the PCI bus). The chip actively controls the fan speed as a
function of temperature (refer to the description of the Ultra-Flow Cooling
System below for more details). In addition, failure of any of the three fans
contained in the PC Workstation will be detected by this chip. The LM75
chip monitors the output of a third temperature sensor situated at the
processor(s).
DiagTOOLS The DiagTOOLS utility must be used when changing a hardware
component. It can currently be downloaded from HP’s World Wide Web
(WWW) site (refer to page 14). In future releases, the creation of a bootable
DiagTOOLS diskette will be possible directly from the TopTools utility.
Ultra-Flow Cooling
System
The HP TopTOOLS hardware monitoring utility uses three temperature
sensors (located at the processor(s), at the hard disk drives and near the
AGP slot) to control the speeds of three fans in the PC Workstation. A fourth
fan is built into the power supply assembly and operates independently of the
temperature sensors. Air flow guides direct the movement of cooling air over
critical components such as the processor(s).
NOTE The lower front fan is integrated in a single hardware part with the internal
speaker. The fan + speaker assembly is removed by sliding the unit out of the
side of the PC Workstation chassis. Similarly, the upper rear fan is integrated
with the airflow guide, and is removed by pressing the buttons on the left and
right bezels (refer to the diagram on page 9).

New HP BIOS and Setup Utility Features
New HP BIOS and Setup Utility Features
Available Languages HP BIOS and the Setup utility are now available in 11 European languages.
Summary Configuration
Screen
A summary screen showing the PC Workstation’s configuration can be viewed
by pressing during POST.
Boot Priority The Setup utility now includes a Boot Menu, where you may 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.
Boot Priority Override An override on the boot priority can be made temporarily by pressing
during POST. A Boot Menu will appear on the screen, allowing a new boot
device to be chosen. This is only a temporary override, and the boot priority
will revert to that specified in the Setup utility for future boots.
Multiprocessing/
Uniprocessing
In dual processor models, the second processor (Processor 2) may be
disabled using the Setup utility option found in the Multiprocessing Menu,
located under the Advanced Menu.
Checking and Changing the System Configuration
HP Setup is accessed by pressing during POST when prompted. The
utility is menu-driven using the keyboard.
Flashing the Latest
Version of the System
BIOS
BIOS upgrades (English versions only) can be downloaded, onto diskettes,
from the HP World Wide Web site (refer to page 14). Multi-lingual BIOS
upgrades are available online from the Customer Support Center. Following
the instructions which you are given, you will obtain the flash utility
programs, FLASH.BAT and PHLASH.EXE, the BIOS file, and a file called
HB1xxxyy.FUL, (where xxx is the version number and yy is the language
number) on a DOS-bootable diskette. Insert the diskette into Drive A:.
Reboot the system. Enter the command: FLASH.

7
Recovery Boot Active Procedure (Force BIOS flash, Switch 10 Down Position)
Recovery Boot Active Procedure
(Force BIOS flash, Switch 10 Down Position)
If, for example, during a BIOS flash, the procedure is interrupted by a power
failure, and the system does not restart, then you can force a BIOS flash.
However, it should be noted that during the 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 device are initialized).
To force a BIOS flash, do the following steps:
1Ensure that you have created a DOS-bootable diskette (1.44 MB diskette
only). This floppy diskette contains all the recovery and system BIOS pro-
gramming software (phlash.exe, platform.bin and hb1xxxyy.Ful). Include
the flash command in the autoexec.bat, for example: phlash /mode=3
hb1xxxyy.Ful
2Turn off the computer.
3Set Switch 10 to the DOWN position (=on).
4Insert the DOS-bootable diskette.
5Power on the computer.
6During the recovery process, short beeps are emitted. The recovery
process is finished when there is a much longer beep (approximately
around 1 to 2 minutes).
7Power off the computer. Press the power ON/OFF button (for about 5
seconds), until the ON/OFF light switches off. Set the Switch 10 to the UP
position (=off).

8
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.
POST and Error Codes
A list of all POST (Power-On Self-Test) and error codes are available
through electronic files from the Support Center.
If you wish to view the POST details, press the key when the Kayak
logo is being displayed at power on, and the checkpoint code of the test
currently in progress will appear in the upper right corner of the screen.
When POST is completed, the HP Summary Screen will appear.
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. “2E1020” means data bits 12 and 5(bits 12 and5 set) have failed
in the lower 16 bits.

Installing/Replacing Processors
Installing/Replacing Processors
All models of the HP Kayak XU PC Workstation are equipped with two
processor sockets. Some models are supplied with dual processors already
installed, while in single-processor models an optional second processor
may be installed in the empty socket.
Each processor is accompanied by its own voltage regulator module (VRM).
The operating system must be configured to use the second processor. Note
that not all operating systems support two processors.
• When there is no second processor, there is a blank terminator on the pro-
cessor socket which must be removed before installing the new processor.
• When installing a second processor, make sure that it is of the same type
as the first.
• The second processor must have the same speed and cache memory size
as the first.
• If the original processor is replaced by a faster processor, the configura-
tion switches must be changed (see below). If two processors are in-
stalled, both must be set to operate at the same bus frequency and
processor frequency.
• Note that after installing a second processor, the operating system must
be reinstalled in order to benefit from the dual processor system. Refer to
page 14 for information concerning the reinstallation of the operating sys-
tem.
