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
XA-s Minitower, XU Series 03xx, and XW Series U3 and W3 PC
Workstations.
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 XA-s, or XU, or XW) BIOS version,
serial number, the number of processors and speed, size of memory
for each DIMM socket.
Use this button to scroll
through the menu items
Use this button
to validate a
menu item

12
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).

13
HP MaxiLife Utility
Test Error Code Action to Take
1When pressing one of the LCD status
panel buttons, nothing is displayed.
2When the system is powered on, nothing is
displayed.
LCD status panel is
blank
• Check that the two cables to the LCD status panel are properly
connected (refer to the system board layout for position).
• Check that the PC’s power cable is plugged in.
Presence of either CPU or Terminator in the
processor slot.
CPU SOCKET • Check CPUs and Terminator and VRM of installed processor.
Control of some voltages: VRMs, 12V POWER SUPPLY • Check the power supply connectors, VRM, CPU. In a single
processor system, check that the VRM is not plugged into the
terminator socket.
The error message could also show: Power CPU1 and Power
CPU2.
Number of installed DIMMs NO RAM • Check that the memory module is correctly installed in the
memory socket.
Compatibility of DIMMs. The BIOS checks that
the inserted DIMMs are both compatible with
one another, and compatible with the Front Side
Bus frequency.
RAM TYPE • Check the installed memory modules. This error occurs when
mixing incompatible memory modules, for example, when
installing a 66 MHz DIMM on a 350 MHz or higher system, or
when mixing Unbuffered and Registered memory modules.
Check the system board clock generators (PLL). BOARD PLL • Check the power supply connector.
• Replace the system board (PLL clock generator).
Test of the correct power signals to the CPU.
The power supply may be OK, whereas the VRM
is not.
POWER • Check that the VRM, processor and terminator are correctly
installed.
• Check that the VRM is not plugged on a socket with a
terminator (this could be the likely cause).
• Check or replace the VRM.
• Check the power supply unit connectors.
Availability of video controller. It is also checked
by the BIOS. If an error is detected, it is not a
fatal one and the BIOS will continue its
execution normally.
NO VIDEO • Check that the video controller is correctly installed.
Note: No error is detected if a monitor is not connected to an
installed video controller.
In order to detect whether the CPU is able to run
a given code, HP MaxiLife waits for a
synchronization event from the BIOS. Any failure
that prevents the execution of the firmware will
trigger an error.
BIOS • Flash the latest version of the system BIOS by using the system
recovery procedure. Set switch 10 to the down position.
• Check that the RAM is correctly installed.
• Check that the CPU is firmly inserted.

14
HP MaxiLife Utility
Special Cases 1If a CPU is not installed correctly.
Either the “Power CPUx” or “CPU socket” or “BIOS” message may
appear. This will depend on which end of the CPU connector is not
correctly inserted.
2If a VRM is installed and there is a terminator in the associated
CPU socket.
MaxiLife displays “Power” error message and the system does not
start
3Only one pre-boot error reported on the system.
Hidden errors will be revealed when the current error has been
fixed.
4If a “No Video Error” message is displayed, even though the video
is working correctly.
With some specific add-on boards (for example, 1540 from
Adaptec with SCSI BIOS), this error may appear while the system
is fully working. To check if this is the case, remove all add-on
boards from the basic system configuration.
1. Special cases: Board PLL = System board needs replacing. CPU error = Reset or power off the system to recover.
The BIOS then executes the Power On Self Test
(POST) sequence. In this phase, HP MaxiLife
waits for any error messages that the BIOS may
issue.
POST XXXX • If the screen is working, you can obtain the signification of the
error by typing “Enter” at the end of the POST. Or, you can
check the list of errors that are available on the HP World-Wide
Web support page.
During normal usage of the PC, HP MaxiLife is
always checking vital parameters of the system.
If an error should occur, a message would be
automatically displayed on the LCD panel.
FAN CPU • Check the connection of the corresponding component, which
could be: “Temp IO slot”, “Power errors, “Fan CPU”, “Board
PLL”, “Temp disk”, “Temp CPU”, “Fan disk”, “Fan IO slot”, “CPU
error”.1

can be checked through the System Info menu.

17
Checking the Display Screen
Checking the Display Screen
When the PC is turned on, the HP MaxiLife diagnostics utility will first check
the system components before it initiates the system startup sequence. If it
detects an error at this stage of the pre-boot checks, an error screen will be
displayed on the LCD status panel. If no errors are found, another screen
with a “smiling icon” will be displayed.
Following the pre-boot checks, the POST sequence is then initiated. If an
error is detected, a POST Error code is displayed. Refer to the POST error
codes table contained in the Service Handbook for further explanation.
I have turned on the PC Workstation, but nothing appears on the
screen. How can I find out what the problem is?

MB modules are non-buffered ECC SDRAM modules, while the 256 MB
modules are registered ECC SDRAM modules. Refer to the table on page 5
for details on how much main memory can be installed on each PC
Workstation.
Mixing Memory Modules
Unbuffered and Registered ECC modules are not compatible with each
other, and cannot be mixed. If these have been mixed, this will be
detected in the basic pre-boot tests when you boot the system for the
first time. The BIOS checks that the inserted DIMMs are compatible with
one another, and if it detects an error, it is reported to the HP MaxiLife.
The error message (shown on the left) will then be displayed on the LCD
status panel. Refer to the following table for DIMM compatibility rules.
1. All DIMMs will function as Non-ECC.
HP XU and XW PC Workstations support only ECC DIMMs.

The PC Workstation has 64 MB of Non-ECC SDRAM main memory
installed in one DIMM slot. Can a 256 MB ECC SDRAM memory
module be added to a second DIMM slot to upgrade the memory?
No. To upgrade the memory, you can use 64 MB or 128 MB
memory modules (either ECC or Non-ECC). Or, alternatively,
replace the existing 64 MB memory module and install a 256
MB ECC SDRAM memory module.

Installing the OpenGL Graphics Drivers
Installing the OpenGL Graphics Drivers
On the HP Kayak XW Series U3 and W3 PC Workstation
OpenGL graphics drivers are available for both the AccelEclipse and
Visualize FX4 video controllers for use under Windows NT4.0 only. Without
the appropriate drivers, the PC Workstation will only operate in VGA mode,
meaning that the 3D hardware accessory will not be available.
NOTE Graphics drivers are regularly updated by Hewlett-Packard for feature and
performance improvements. When installing a driver, or diagnosing an error,
you are strongly recommended to check that you have the latest driver
version. These can be found on the HP World Wide Web site:

Installing the OpenGL Graphics Drivers
Installation of the drivers is done through the standard process:
Display Properties / Settings / Display Type
Configuring the AccelEclipse OpenGL Driver
Once the driver is installed, an ‘AccelEclipse’ tab is added to the Display
Properties dialog box.
