Identifying the Latest Kayak XU PC Workstation
Identifying the Latest Kayak XU PC Workstation
As well as the above-mentioned differences between the two HP Kayak XU
models, the Kayak XU Series 0441 model incorporates the new HP designed
system board based on the Intel®440GX AGPset supporting up to 2 GB of
Registered memory modules.
The following table shows the comparison between the HP Kayak XU
models.

frequency of 400 MHz or 450 MHz on a 100 MHz
system bus.
Pentium II Slot 1 processor(s) with an operating
frequency of 350 MHz or 400 MHz on a 100 MHz
system bus.

GLoria Synergy video controller.
How can I distinguish the difference between the latest HP Kayak
XU model Series 0441 and the previous HP Kayak XU models Series
0301 and Series 0303?
There are three simple and quick ways to identify the latest HP
Kayak XU model. First, the label on the side of the newer Kayak
XU indicating “Series 0441”. Secondly, the processor is an Intel
Pentium II Xeon, and finally the system package with
reinforced processor cage.

Preparing to Remove the System Board
Preparing to Remove the System Board
Due to the fact that the Intel Pentium II Xeon processor weighs about 1 kg,
the system board can be damaged because of vibration if it is not securely
set in place.
The system board on the Kayak XU Series 0441 PC Workstation is secured to
the PC chassis by seven screws. These screws are longer than the standard
ones used on the PC Workstation and are not available as spare parts. If you
do lose or mislay any of these screws, there are four spare ones located on
the front of the chassis (underneath the audio front panel). These screws
are to be used uniquely to secure the system board.
Before attempting to remove the system board, you will have to first
unscrew these screws. Six of them can be accessed from the outside of the
chassis, while the seventh screw is located near PCI Slot 3.

Connecting to the LAN/SCSI Combination Board
Connecting to the LAN/SCSI Combination Board
The HP Kayak Series 0441 PC Workstation contains a SCSI/LAN
10BT/100TX combination board which is installed in PCI Slot 4. This
combination board includes two connectors:
• Wake On LAN (WOL) which enables a host computer, using Magic Packet
technology, to remotely (over the network) power on computers (Remote
Power On) or wake them up (Remote Wake Up) from energy-saving Sleep
mode.
For these functions to work, the WOL cable must be connected
between the SCSI/LAN Combination board, located at the bottom right-
hand-side corner (J8) and the WOL connector on the system board (J20).
• External Start connector which enables LAN activity, the SCSI LED
activity on the front panel for SCSI hard disk drive accesses, and external
SCSI cable detection.
The external cable must be connected to the internal connector (J4) on
the bottom right-hand-side of SCSI/LAN combination board to the HP
External Start connector (R403) on the system board.
LAN/SCSI Combination Board
NOTE Do not connect any devices to the Internal Narrow SCSI, and to the Internal
Wide SCSI at the same time. If you do, this results in a badly “terminated”
SCSI bus. In the HP Kayak XU and XW PC Workstations, only an Internal
Narrow SCSI cable is provided.

HP MaxiLife Utility
HP MaxiLife Utility
HP MaxiLife is a hardware monitoring chip which is resident on the system
board. This chip receives data about the various system components via a
dedicated I2C bus. If it detects a potential error or that a component is in an
error state (for example, there is a CPU failure), it displays a warning with a
flashing LED and message on its LCD that specifies which component has
the problem.
Due to HP MaxiLife’s system independent design, even if there is a serious
component failure, it remains in operation and is able to indicate what the
problem is via the LCD.
For the HP MaxiLife to work correctly, the PC Workstation must always be
connected to a grounded outlet. This enables the PC Workstation’s hardware
monitoring chip to be active, even if the system has been powered off.
The following diagram shows where the LCD is located on the HP Kayak
XU Series 0441 PC Workstation.
The following menus are available on the HP MaxiLife utility when pressing
the menu button:
•System Info. Obtains information from the BIOS and the system’s Serial
EEPROM from a previously successful boot. This information includes:
product name (HP Kayak XU) BIOS version, serial number, the number
of processors and speed, size of memory for each DIMM socket.

HP MaxiLife Utility
•Boot Steps. Shows the Power-On Self Test (POST) codes during the
system startup. The POST code is provided by the BIOS and is displayed
on the LCD panel as soon as it is available. If the system stops during the
startup, the last successful boot step POST code is displayed on the LCD.
Diagnostics. Runs a set of diagnostics assessing the system’s
components. Results of the tests are displayed on the LCD one after
another when the user presses the button.
Result of the diagnostics is: OK/FAIL.
Error Messages
When the PC is turned on (pressing the ON/OFF button), the system
initiates the normal startup sequence. A first diagnostic (called pre-boot
diagnostics) is run to check the presence of the processor, DIMM, VRM and
power supply.
MaxiLife does not purposely ‘freeze’ the system if an error is detected.
However, some critical hardware errors are fatal to the system and will
prevent the system from starting (for example, ‘Power’, ‘Board PLL’ are
serious malfunctions that will prevent the CPU to work correctly).
Errors that are not so critical (for example, ‘CPU Socket’ for missing
terminator, or ‘NO RAM’) are also detected by the POST and will abort its
own boot process after beeping. The ‘RAM type’ error is only detected by
POST with the same abort process.
Finally, while the PC is working, fan and temperature controls can be
reported (for example, a fan error when a cable is not connected). This type
of error disappears dynamically when the problem has been fixed (for
example, the fan cable has been reconnected).
If an error is detected, a screen appears on the LCD panel. The following
table shows the test sequence carried out, the type of error message, and
the action to take.The errors mentioned are standard error codes (they are
displayed without the need of pressing any key on the LCD status panel).
