1 System Overview
HP Kayak XU700 Minitower Specifications and Characteristics
If the overload protection in the power supply unit is triggered, all power is
immediately cut. To reset the power supply unit, remove the power cord and
then determine what caused the overload and remedy it. Reconnect the
power cord, then reboot the PC Workstation. If an overload happens twice,
then there is an undetected short circuit somewhere.
NOTE
When the PC Workstation is turned off with the power button on the front
panel, the power consumption falls below the low power consumption (refer
to the below table), 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.
Power Consumption and Cooling
The power consumption and acoustics given in the below table is valid for a
standard configuration as shipped (one processor, 256 MB of memory,

AGP Slot
Minitower models of the HP Kayak XU700 are equipped with a single AGP
(Accelerated Graphics Port) graphics slot.
The AGP Pro Universal slot provides the ultimate graphics performance for
high-end graphics cards, combining AGP 4X bandwidth (with data transfer
rates up to 1056 MB/sec) with the ability to accept high-end graphics cards
drawing up to 50 W of power.
To accommodate AGP Pro cards, the AGP PRO slot connector is wider than
the standard AGP 4X connector. Additional pins have been added at both
ends of the connector to meet the increased power requirements of AGP
Pro graphics cards.
An AGP Pro card may draw power either from the existing part of the AGP
Pro connector, the extended part, or a combination of the two. In all cases,
the maximum power that may be drawn by an AGP Pro card is limited to
50 W in the Minitower models. Power on the existing part of the connector
is delivered on 5.0 V and 3.3 V rails. Power on the extension is delivered on
the 12 V and 3.3 V rails.
30
2 System Board
Accessory Board Slots
Either standard AGP graphics cards or AGP Pro graphics cards drawing less
than 50W of power can be used (below 25W a standard AGP connector may
be used), with power being provided through 3.3 V, 5 V, or 12 V power rails.
NOTE
AGP Pro graphics cards drawing more than 50W (“high-power” AGP Pro
cards) and AGP 3.3V graphics cards cannot be used in the Minitower’s AGP
slot.
The AGP Pro Universal slot is backwards compatible with both AGP 1x and
2.x modes (using 1.5 V signalling), and AGP 4x mode (where 1.5 V signalling
is required).
The AGP interface and bus are explained on page 38.
PCI Slots
There is a total of five Peripheral Component Interconnect (PCI) 32-bit,
33 MHz connectors on the system board.
The PCI slots accept 3.3 V and 5 V PCI 32-bit 33 MHz cards, and Universal
PCI cards (which are 3.3 V or 5 V compatible). Refer to the table on the
following page for the different PCI board installations.
The maximum supported power consumption per slot is 25W, either from
the 5V or the 3.3V supply and must respect the electrical specifications of
the PCI 2.2 specification. Total power consumption for the PCI slots must
not exceed 60 W.
The power consumption of each PCI board is automatically reported to the
system through the two Presence Detect pins of each PCI slot. These pins
code the following cases:
• No accessory board in the PCI slot.
• 7 W maximum PCI board in the PCI slot.
• 15 W maximum PCI board in the PCI slot.
• 25 W maximum PCI board in the PCI slot.

MCH Interface
The MCH interface provides bus control signals and address paths via the
Hub Link 8-bit access to the ICH2 for transfers between the processor on
the system bus, Dual Rambus bus and AGP 4x bus.
The MCH supports 32-bit host addresses, allowing the processor to address
a space of 4GB. It also provides an 8-deep In-Order Queue supporting up to
eight outstanding transaction requests on the system bus.
Host-initiated input/output signals are positively decoded to AGP or MCH
configuration space and subtractively decoded to Hub Link 8-bit interface.
Host-initiated memory cycles are positively decoded to AGP or RDRAM, and
are again subtractively decoded to Hub Link 8-bit interface.
AGP semantic memory accesses initiated from AGP to DRAM do not require
a snoop cycle (not snooped) on the System bus, since the coherency of data
for that particular memory range will be maintained by the software.
However, memory accesses initiated from AGP using PCI Semantics and
accesses from Hub Link interface to RDRAM do require a snoop cycle on the
System bus.
Memory access whose addresses are within the AGP aperture are translated
using the AGP address translation table, regardless of the originating
interface.
Write accesses from Hub Link interface to the AGP are supported.
37
2 System Board
Memory Controller Hub (82850)
The MCH supports one Pentium 4 processor at an FSB frequency of 100MHz
using AGTL+ signalling. Refer to page 56 for a description of the System bus.
Accelerated Graphics Port (AGP) Bus Interface
A controller for the Universal AGP (Accelerated Graphics Port) Pro slot is
integrated in the MCH. The AGP Bus interface is compatible with the
Accelerated Graphics Port Specification, Rev 2.0, operating at 133 MHz, and
supporting up to 1 GB/sec data transfer rates. The MCH supports only a
synchronous AGP interface, coupling to the System bus frequency.
AGP 4x Bus
The AGP bus is a dedicated bus for the graphics subsystem, which meets the
needs of high quality 3D graphics applications. It has a direct link to the
MCH.
The AGP bus is based upon a 66 MHz, 32-bit PCI bus architecture, to which
several signal groups have been added to provide AGP-specific control and
transfer mechanisms.
AGP specific transactions always use pipelining. This control mechanism
increases the bus efficiency for data transfer. Sideband Addressing (SBA)
may also be used by AGP transaction requests which further increases the
bus efficiency for data transfer. The supported modes are detailed below:
•
•
•
•
38
FRAME-based AGP. Only the PCI semantics are: 66 MHz, 32-bit, 1.5 V,

A maximum number of 32 Rambus devices (128 Mbit technology implies 1
GB maximum in 32 MB increments, 256 Mbit technology implies 2 GB
maximum in 64 MB increments) are supported on the Direct Rambus
channel without external logic.
The MCH also provides optional data integrity features including ECC in the
memory array. During DRAM writes, ECC is generated on a QWord (64 bit)
basis. During DRAM reads, the MCH supports multiple-bit error detection
and single-bit error correction when the ECC mode is enabled.

Memory Controller Hub (82850)
MCH will scrub single bit errors by writing the corrected value back into
DRAM for all reads when hardware scrubbing is enabled. This, however does
not include reads launched in order to satisfy an AGP aperture transaction.
ECC can only be enabled when all RDRAM devices are populated in a system
that supports the extra two data bits used to store the ECC code.
Dual Rambus Bus
The Dual Rambus bus is comprised of 16 x 2 bits of data information, and
8 bits of Error Correcting Code (ECC). The bus is connected to the RIMM
memory slots and to the MCH chip supporting two Dual Rambus channels
(A and B).
Both channels run at 300 or 400 MHz supporting up to 32 rambus devices
per channel. The maximum available data bandwidth is 3.2 GB/s at 400 MHz.
The configuration of both primary rambus channels must be symmetrical –
the memory configuration on channel A must be identical to the memory
configuration on channel B. This means the memory must be installed in
identical pairs.

Memory Controller Hub (82850)
RIMM Memory Slots
The HP Kayak XU700 PC Workstation has four RIMM memory sockets,
RIMM A1, RIMM A2, RIMM B1, RIMM B2, for installing two or four RDRAM
memory modules.
Each pair of memory sockets must contain identical memory modules
(identical in size, speed and type). That is, sockets A1 and B1 must contain
identical modules, and sockets A2 and B2 must contain identical modules
(or continuity modules).
If only two RDRAM modules are installed, use the sockets marked A1 and
B1. The other two sockets (A2 and B2) must contain continuity modules.
If only Each DIMM socket is connected to the SMBus and is described on
page 49.
Read/Write Buffers
The MCH 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).
System Clocking
The MCH operates the System interface at 100 MHz or, PCI at 33 MHz and
AGP at 66/133 MHz. Coupling between all interfaces and internal logic is
done in a synchronous manner. The clocking scheme uses an external clock
synthesizer (which produces reference clocks for the host, AGP and PCI
interfaces).

The Input/Output Controller Hub 2 (82801BA)
ICH2 Architecture
The ICH2 interface architecture ensures that the I/O subsystems, both PCI
and the integrated input/output features (for example: IDE, AC’97 and USB)
receive the adequate bandwidths.
To achieve this, by placing the I/O bridge directly on the ICH2 interface, and
no longer on the PCI bus, the ICH2 architecture ensures that both the
input/output functions integrated into the ICH2 and the PCI peripherals
obtain the bandwidth necessary for peak performance.
ICH2 PCI Bus Interface
The ICH2 PCI provides the interface to a PCI bus interface operating at
33 MHz. This interface implementation is compliant with PCI Rev 2.2
Specification, supporting up to five external PCI masters in addition to the
ICH2 requests. The PCI bus can reach a data transfer rate of 133
MBytes/sec. The maximum PCI burst transfer can be between 256 bytes and
4 KB. It also supports advanced snooping for PCI master bursting, and
provides a pre-fetch mechanism dedicated for IDE read.
Refer to the table page 59 for ICH2 interrupts.
SMBus Controller
The System Management (SM) bus is a two-wire serial bus which runs at a
maximum of (100 kHz). The SMBus Host interface allows the processor to
communicate with SMBus slaves and an SMBus Slave interface that allows
external masters to activate power management events. The bus connects
to sensor devices that monitor some of the hardware functions of the system
board, both during system boot and run-time.
Refer to page 47 for a description of the devices on the SMBus, or to page 50
for information on the MaxiLife ASIC.
Low Pin Count Interface The ICH2 implements the LPC interface 1.0 specification.
Enhanced USB Controller The USB (Universal Serial Bus) controller provides enhanced support for
the Universal Host Controller Interface (UHCI). This includes support that
allows legacy software to use a USB-based keyboard and mouse. The USB
supports four stacked connectors on the back panel. These ports are built
into the ICH2, as standard USB ports.
The ICH2 is USB revision 1.1 compliant.
USB works only if the USB interface has been enabled within the HP Setup
program. Currently, only the Microsoft Windows 95 SR2.1, Windows 98 and
Windows 2000 operating systems provide support for the USB.

The Input/Output Controller Hub 2 (82801BA)
AC’97 Controller
This is the single-chip CS4299 audio controller that provides full audio
features for the Kayak XU700.
Refer to page 46 for information about the CS4299 audio solution.
IDE Controller
The IDE controller is implemented as part of the ICH2 chip and has PCIMaster capability. Two independent ATA/100 IDE channels are provided
with two connectors per channel. Two IDE devices (one master and one
slave) can be connected per channel. In order to guarantee data transfer
integrity, Ultra-ATA cables must be used for Ultra-ATA modes (Ultra-ATA/33,
Ultra-ATA/66 and Ultra-ATA/100).
The PIO IDE transfers of up to 14 Mbytes/sec and Bus Master IDE transfer
rates of up to 66 Mbytes/sec are supported. The IDE controller integrates
16 x 32-bit buffers for optimal transfers.
It is possible to mix a fast and a slow device, such as a hard disk drive and a
CD-ROM, on the same channel without affecting the performance of the fast
device. The BIOS automatically determines the fastest configuration that
each device supports.
DMA Controller
The seven-channel DMA controller incorporates the functionality of two
82C37 DMA controllers. Channels 0 to 3 are for 8-bit count-by-byte
transfers, while channels 5 to 7 are for 16-bit count-by-word transfers (refer
to table on page 93 for allocated DMA channel allocations). Any two of the
seven DMA channels can be programmed to support fast Type-F transfers.
The ICH2 DMA controller supports the LPC (Low Pin Count) DMA. Single,
Demand, Verify and Incremental modes are supported on the LPC interface.
Channels 0-3 are 8-bit, while channels 5-7 are 16-bit. Channel 4 is reserved
as a generic bus master request.
Interrupt Controller
The Interrupt controller is equivalent in function to the two 82C59 interrupt
controllers. The two interrupt controllers are cascaded so that 14 external
and two internal interrupts are possible. In addition, the ICH2 supports a
serial interrupt scheme and also implements the I/O APIC controller. A table
on page 59 shows how the master and slave controllers are connected.
45
2 System Board
The Input/Output Controller Hub 2 (82801BA)
Timer/Counter Block
The timer/counter block contains three counters that are equivalent in
function to those found in one 82C54 programmable interval counter/timer.
These three counters are combined to provide the system timer function,
and speaker tone. The 14.318 MHz oscillator input provides the clock source
for these three counters.
Advanced Programmable Incorporated in the ICH2, the APIC can be used in either single-processor or
multi-processor systems, while the standard interrupt controller supports
Interrupt Controller
only single-processor systems.
Real Time Clock
The RTC is 146818A-compatible, with 256 bytes of CMOS. The RTC
performs two key functions: keeping track of the time of day and storing
system data.
The RTC operates on a 32.768 kHz crystal and a separate 3V lithium battery
that provides up to 7 years of protection for an unplugged system. It also
supports two lockable memory ranges. By setting bits in the configuration
space, two 8-byte ranges can be locked to read and write accesses. This
prevents unauthorized reading of passwords or other security information.
Another feature is a date alarm allowing for a schedule wake-up event up to
30 days in advance.
Enhanced Power
Management
The ICH2’s power management functions include enhanced clock control,
local and global monitoring support for 14 individual devices, and various
low-power (suspend) states. A hardware-based thermal management circuit
permits software-independent entry points for low-power states.
The ICH2 includes full support for the Advanced Configuration and Power
Interface (ACPI) specifications.
Crystal CS4299 Integrated PCI Audio
Based on the earlier Crystal audio controller, the CS4299 extends these
features to include, among many other enhancements, PC’98 and PC’99

ICH2 SMBus Master
Controller
The ICH2 provides a processor-to-SMBus controller. All access performed to
the SMBus is done through the ICH2 SMBus interface. Typically, the
processor has access to all the devices connected to the SMBus.
DIMM Sockets
Each DIMM socket is connected to the SMBus. The 168-pin DIMM modules
include a 256 byte I2C Serial EEPROM. The first 128 bytes contain general
information, including the DRAM chips’ manufacturer’s name, DIMM speed
rating, DIMM type, etc. The second 128 bytes of the Serial EEPROM can be
used to store data online.
RIMM Sockets
Each RIMM socket is connected to the SMBus. The 168-pin RIMM modules
include a 256 byte I2C Serial EEPROM. The first 128 bytes contain general
information, including the DRAM chips’ manufacturer’s name, RIMM speed
rating, RIMM type, etc. The second 128 bytes of the Serial EEPROM can be
used to store data online.
ADM1024
The ADM1024 chip is a hardware monitoring sensor dedicated to the
processor temperature. This chip uses the thermal diodes integrated into
each processor cartridge and makes the temperature information available
through the SMBus. It also monitors processor power supply voltages.
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 16KBytes of Serial EEPROM implemented within two
chips. 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 as well as MaxiLife firmware.
LM75 Temperature
Sensor
The LM75 temperature sensor and alarm are located on the system board.
The sensor is used to measure the temperature in various areas of the
system board. This information is used to regulate fans.

HP MaxiLife Hardware
Monitoring Chip
MaxiLife is a hardware monitoring chip which is resident on the system
board. Its responsibility includes On/Off and reset control, status panel
management (Lock button, LEDs), hardware monitoring (temperature and
voltage), early diagnostics (CPU, memory, PLLs, boot start), run-time
diagnostics (CPU errors), fan speed regulation, and other miscellaneous
functions (such as special OK/FAIL symbols based on a smiling face).
The integrated microprocessor includes a Synopsys cell based on Dallas
“8052” equivalent, a 2 KB boot ROM, 256 bytes of data RAM, an I2C cell, an
Analog-to-Digital (ADC) with 5 entries, and an additional glue logic for
interrupt control, fan regulation, and a status panel control.
MaxiLife downloads its code in 96 milliseconds from an I2C serial EEPROM.
The total firmware (MaxiLife 8051-code, running in RAM) size is 14 KB. As
it exceeds the 2 KB program RAM space, a paging mechanism will swap
code as it is required, based on a 512 byte buffer. The first 2 KB pages of
firmware code is critical because it controls the initial power on/reset to
boot the system. This initial page is checked with a null-checksum test and
the presence of MaxiLife markers (located just below the 2 KB limit).
MaxiLife is not accessible in I/O space or memory space of the system
platform, but only through the SMBUS (which is a sub-set of the I2C bus),
via the ICH2. Its I2C cell may operate either in Slave or Master mode,
switched by firmware, or automatically in the event of ‘Arbitration’ loss.
As a monitoring chip, MaxiLife reports critical errors at start-up, and is
therefore powered by Vstandby (3.3V) power. For MaxiLife to work, the PC
Workstation must 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.

FirmWare Hub (82802AB)
The FWH includes two hardware interfaces:
•
FirmWare Hub interface.
•
Address/Address Multiplexed (A/A Mux) interface.
The IC (Interface Configuration) pin on the FWH provides the control
between these interfaces. The interface mode needs to be selected prior to
power-up or before return from reset (RST# or INIT# low to high
transition).
The FWH interface works with the ICH2 during system operation, while the
A/A Mux interface is designed as a programming interface for component
pre-programming.
An internal CUI (Command User Interface) serves as the control center
between the FWH and A/A Mux interfaces, and internal operation of the
non-volatile memory. A valid command sequence written to the CUI initiates
device automation. An internal WSM (Write State Machine) automatically
executes the algorithms and timings necessary for block erase and program
operations.

System Bus
System Bus
The system bus of the Pentium 4 processor is implemented in the GTL
(Gunning Transceiver Logic)+ technology. This technology features opendrain signal drivers that are pulled up through resistors at bus extremities to
the operating voltage of the processor core. These resistors also act as bus
terminators, and are integrated in the processor and in the 82850 MCH.

The supported operating frequency of the GTL+ bus for the Pentium 4 is
100 MHz. The width of the data bus is 64 bits, while the width of the address
is 32 bits. Data bus transfers occur at four times the system bus, at 400 MHz.
Along with the operating frequencies, the processor voltage is set
automatically.
The control signals of the system bus allow the implementation of a “split transaction” bus protocol. This allows the Pentium 4 processor to send its
request (for example, for the contents of a given memory address) and then
to release the bus, rather than waiting for the result, thereby allowing it to
56
2 System Board
System Bus
accept another request. The MCH, 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 4 Processor
The Pentium 4 processor has several features that enhance performance:
•
•
•
•
•
•
Data bus frequency of 400 MHz.
Dual Independent Bus architecture, which combines a dedicated 64-bit
L2 cache bus (supporting 256 KB) plus a 64-bit system bus that enables
multiple simultaneous transactions.
MMX2 technology, which gives higher performance for media,
communications and 3D applications.
Dynamic execution to speed up software performance.
Internet Streaming SIMD Extensions 2 (SSE2) for enhanced floating
point and 3D application performance.
Uses multiple low-power states, such as AutoHALT, Stop-Grant, Sleep and
Deep Sleep to conserve power during idle times.
The Pentium 4 processor is packaged in a pin grid array (PGA) that fits into
a PGA423 socket (423-pin Zero Insertion Force or ZIF socket).
Processor Clock
The 100 MHz System Bus clock is provided by a PLL. The processor core
clock is derived from the System Bus by applying a “ratio”. This ratio is fixed
in the processor. The processor then applies this ratio to the System bus
clock to generate its CPU core frequency.
Bus Frequencies
There is a 14.318 MHz crystal oscillator on the system board. This frequency
is multiplied to 133 MHz by a phase-locked loop. This is further scaled by an
internal clock multiplier within the processor.
The bus frequency and the processor voltage are set automatically.
Voltage Regulation
Module (VRM)
One VRM is integrated on the system board complying with VRM
specification rev. 9.0. High-current and low voltage processors are
supported.
The processor requires a dedicated power voltage to supply the CPU core
and L2 cache. The processor codes through Voltage Identification (VID)
pins with a required voltage level of 1.30 V to 2.05 V. The VID set is decoded
57
2 System Board
System Bus
by the VRM on the system board that in return supplies the required power
voltage to the processor. It should be noted, however, that voltage may vary
from one processor model to another.
Cache Memory
The Pentium 4 integrates the following cache memories on the same die as
the processor cache:
•
A trace instruction and L1 data cache. The trace cache is 4-way set associative.
•
A 256KB L2 cache. The L2 cache is 8-way associative.
The amount of cache memory is set by Intel at the time of manufacture, and
cannot be changed.

Interrupt Controllers
The system has an Interrupt controller which is equivalent in function to
that of two 82C59 interrupt controllers. The following table shows how the
interrupts are connected to the APIC controller. The Interrupt Requests
(IRQ) are numbered sequentially, starting with the master controller, and
followed by the slave (both of 82C59 type).
59

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 interrupts are
allocated dynamically.

In PIC mode, the Interrupts signaled to the P64H are chained as INTC to the ICH2.
There are three major interrupt modes available:
PIC mode: This mode uses only the “Legacy” interrupt controllers, so that
only one processor can be supported. Because this system has dual
processor capability, this mode is not chosen by default by Windows NT.
However, during Windows NT installation, you have the possibility of
selecting this mode.
60
2 System Board
Assigned Device Interrupts
Virtual wire mode: This mode is implemented with APIC controllers in the
ICH2 and P64H and used during boot time. The virtual wire mode allows the
transition to the “symmetric I/O mode”. In the virtual wire mode, only one
processor executes instructions.
Symmetric I/O mode: This mode is implemented with APIC controllers in
the ICH2 and P64H, and allows for multiple processor operations.
NOTE
In “PIC mode” and “virtual wire mode”, the PCI interrupts are routed to the
INT line. In the “symmetric I/O mode”, the PCI interrupts are routed to the
I/O APIC controllers and forwarded over an APIC bus to the processors.
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, optimal system performance is reached when minimizing the
sharing of interrupts. Refer to page 59 for a table of the PCI device
interrupts.

Adaptec 29160 SCSI PCI Adapter Card
Your Personal Workstation is equipped with an Ultra 160/m SCSI card. The
Adaptec® SCSI card has a system bus rate of 533 MB/Sec, a SCSI data
transfer rate of 160 MB/Sec and the capability of supporting up to 15
peripheral devices.
The Adaptec SCSI card is able to connect to Low-Voltage Differential (LVD)
SCSI devices (for example, Ultra2 and Ultra 160/m) and Single-Ended (SE)
SCSI devices (for example, Ultra SCSI, Fast SCSI, SCSI-1, etc.). Examples of
single ended devices include: DAT drives, Scanners, and older hard disk
drives.

While SE SCSI devices will work when attached to connector 1 or 2, this will
limit all devices to single-ended mode. For example, this would result in the
Ultra 160/m hard disk drive performance being limited from 160 MB/second
to 40 MB/second. Therefore, it is recommended that you connect only LVD
72
3 Interface Cards
SCSI Adapter Cards
SCSI devices to connectors 1 and 2.
For information on how to connect internal an external SCSI devices, please
read your User’s Guide.
SCSI Cable Information
The intended use of the external SCSI connector is to connect Low-Voltage
Differential SCSI devices to your Personal Workstation. This section
provides you with SCSI cable information that is important for the correct
operation of your external SCSI device.
NOTE
The total length of the external SCSI cable should not exceed 10 meters
(approximately 32.81 feet) and there must be at least eight inches of cable
separating each device.
Contact you dealer to order shielded HP SCSI cables to connect external
SCSI accessories.
CAUTION:
Low-voltage differential SCSI is very sensitive to noise, and therefore, all cables on
the SCSI bus must be exceptionally high quality cables. Examples of these are given
in the following table.
Please make sure that any external hard disk enclosures are rated for low-voltage
differential SCSI use.

Additional SCSI Card Features
The Adaptec® SCSI card provides double transition clocking, cyclical
redundancy check, and domain validation.
Feature
Double Transition
Clocking
Description
Changes the digital protocol to use both edges of
the SCSI request/acknowledge signal clock. It
allows designers to use Ultra2 cables. The signal
in an Ultra2 SCSI runs a 40 MHz, while data runs
at only 20 MHz or 80 MB/second on a 16-bit wide
bus.
Using both edges of the same signal at 40 MHz the
data rate can be increased to 40 MB/second or 160
MB/second on a 16-bit wide bus.
Cyclical Redundancy
Check
Provides extra data protection for marginal cables
that are connected to external devices. The Ultra3
SCSI cyclical redundancy check detects all:
•
•
•
•
Domain Validation
74
Single error bits

Odd number of errors
Burst errors up to 32-bits long
Tests networks, cables, backplanes, terminators,

environment is operating at required specification.
If reliability is at risk the speed of transfer is
lowered.

HP BIOS
This chapter summarizes the Setup program and BIOS of the HP Kayak
XU700 PC Workstation. The POST routines are described in the next
chapter.
The BIOS is based on the core Phoenix BIOS, which includes 4 M/bits of
flash memory, support for PCI 2.2 Specification, suspend to RAM, and RIMM
or DIMM memory modules.
The BIOS includes a Boot ROM for the 3COM 3C905C and HP LAN cards.
The System ROM contains the POST (Power-On Self-Test) routines, and the
BIOS: the System BIOS, video BIOS, and low option ROM. This chapter,
together with the subsequent chapter, gives 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 IX.WM, where:
•
•
•
IX is a two-letter code indicating that it is for the Kayak XU700.
W is a one-digit code indicating the HP entity.
M is the major BIOS version.
An example of a released version would look similar to the following the
example: IX.W1.05.
The procedure for updating the System ROM firmware is described on
page 87.

BIOS Addresses
There are three major interrupt modes available:
PIC mode: This “Legacy” mode uses only the interrupt controllers.
Therefore, only one processor can be supported in this mode. This mode
can be selected upon installation of Windows NT.
Virtual wire mode: This mode is implemented using the 82C59 interrupt
and the I/O APIC controller and is used during boot time. The virtual wire
mode allows the transition to the “symmetric I/O mode”. In the virtual wire
mode, only one processor executes operations.
Symmetric I/O mode: This mode is implemented using the I/O APIC
controller and allows for multiple processor operations.
NOTE
In “PIC mode” and “virtual wire mode”, the PCI interrupts are routed to the
INT line. In the “symmetric I/O mode”, the PCI interrupts are routed to the
I/O APIC controllers and forwarded over an APIC bus to the processors.
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, optimal system performance is reached when minimizing the
sharing of interrupts. Refer to page 59 for a table of the PCI device
interrupts.

Tests and Error Messages
This chapter describes the MaxiLife firmware test sequences and error
messages, the pre-boot diagnostics error codes, 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.
MaxiLife Test Sequence and Error Messages
When the PC Workstation is turned on (pressing the ON/OFF button), the
system initiates the normal startup sequence which is composed of the
following steps:
•
•
•
•
Basic pre-boot diagnostics
BIOS launch
POST phase
Operating System boot phase
If any errors are detected during the startup sequence, MaxiLife will not
necessarily ‘freeze’ the system. However, some critical hardware errors are
fatal to the system and will prevent the system from starting (for example,
‘CPU Socket’ and ‘Power Supply’ are serious malfunctions that will prevent
the system from working correctly).
Errors that are not so critical will be detected both during pre-boot
diagnostics and POST where the BIOS boot process will return an error
code. Some errors are only detected during POST sequence, and produce
the same process.
Finally, while the PC Workstation is working, fan and temperature controls
can be reported (for example, a fan error will be reported if a fan cable is not
connected). This type of error disappears as soon as the problem is fixed
(for example, the fan cable has been reconnected).
The different diagnostics are described below.

6 Tests and Error Messages
MaxiLife Test Sequence and Error Messages
Basic Pre-boot Diagnostics
The first diagnostic (called basic pre-boot diagnostics) is run to check the
presence of the processor(s) or terminators, power supply, hardware
monitoring and thermal sensors. Simply by having a power cord connected
to the PC Workstation activates the Basic Pre-boot Diagnostics.
The pre-boot diagnostic tests are run in order of priority with respect to
their importance to computer functions.
On the HP Kayak XU700 PC Workstation, the first detected error displays
a message on the LCD status panel. If this happens, one of the following
screens could appear.

In this phase, MaxiLife waits for any error messages that the BIOS may
issue. If such an error occurs, then an error code is displayed on the monitor
screen.
On the HP Kayak XU700 Minitower PC Workstation, a screen similar to
the following example is displayed. The error code that appears on the LCD
status panel is the same as the one that appears on the monitor screen. If
the POST issues several error codes, only the last one is visible on the LCD

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. When Boot Steps
is selected, the POST step will be shown on the LCD status panel during the
subsequent boot processes.
To ensure that MaxiLife is ready to display the first POST codes as soon as
possible, the Pre-boot diagnostics are not executed when the system is
booted with the Boot Steps option selected. The following diagram shows
how Boot Steps obtains its information from the BIOS, and then displays a
POST error if needed.

Order in Which POST 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 Workstation is restarted. If you wish to view the POST
details, press Esc to get the HP Summary Screen.
If the POST detects an error, the screen switches to text mode, and a
detailed 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 (refer to page 113 for a brief
summary).
On the HP Kayak XU700 Minitower PC Workstation, the LCD status panel
displays either a message, a POST code number (refer to page 105) or an EMU
code.
Devices such as memory and newly installed hard disks, are configured
automatically. The user is not requested to confirm the change.
During the POST, the BIOS and other ROM data are 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.
The following table lists the POST checkpoint codes and their associated
beeps. Refer to page 99 for more details about pre-boot diagnostics error
codes.

If the BIOS detects error 2C, 2E, or 30 (base 512K RAM error), it displays an additional word-bitmap
(xxxx) indicating the address line or bits that failed.For example:
“2C 0002” means 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.
The BIOS also sends the bitmap to the port-80 LED display. It first displays the checkpoint code,
followed by a delay, the high-order byte, another delay, and then the low-order byte of the error. It
repeats this sequence continuously.

Error Message Summary
Error Message Summary
In the event of an error generated in POST (Power-On-Self-Test) during the
boot process, the Error Setup Manager gives access to one or more detected
errors. Each EMU error is displayed as a 4-digit code with an associated text
message on the monitor screen or/and the MaxiLife LCD panel.
Further details can be accessed by pressing ENTER. A detailed description
of the reason for the failure and how to solve the problem is displayed. The
following examples give the different types of error categories.
Category #1:
If the error is only a warning (i.e. key stuck), the POST should prompt:
WARNING1
00100
1.
Keyboard Error
After a time-out period of five seconds without any intervention, the system resumes to boot.
Category #2:
00xx
If the error is serious, the POST should prompt:
The BIOS has detected a serious problem that prevents your PC from booting

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

Clear CMOS.
Video Plug and Play interrupted or
failed. Re-enable in Setup and try again
You may have powered your computer Off/On too quickly and the
computer turned off Video plug and play as a protection.

Explanation or Suggestions for Corrective Action
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.
