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, 320 W power supply, one hard disk drive, graphics card, LAN card).

All information in this section is based on primary power consumptions.

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.

PCI Slot 2

PCI Slot 3

PCI Slot 4

PCI Slot 5

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.

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.

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.

Arbitration:

•

❒ Distributed Arbitration Model for Optimum Concurrency

Support.

❒ Concurrent operations of System, hub interface, AGP and

memory buses supported via a dedicated arbitration and data buffering logic.

Input/Output Device Support:

•

❒ Input/Output Controller Hub (ICH2). ❒ PCI 64 Hub (P64H).

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.

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:

FRAME-based AGP. Only the PCI semantics are: 66 MHz, 32-bit, 1.5 V,

•

266 MB/s peak transfer rate. AGP 1X with pipelining, sideband addressing can be added: uses 66 MHz,

Main Memory Controller

The main memory controller is integrated in the MCH supporting two primary rambus channels (A and B).

DRAM Interface

The MCH provides optional System bus error checking for data, address, request and response signals. Only 400 MHz Direct Rambus devices are supported in any of 128 or 256 Mbit technology. 128 Mbit RDRAM uses page sizes of 1 kbytes, while 256 Mbit devices target 1 kbyte or 2 kbyte pages.

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.

2 System Board

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.

2 System Board

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

System Clocking

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).

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).

2 System Board

The Input/Output Controller Hub 2 (82801BA)

The ICH2 is encapsulated in a 360-pin Enhanced Ball Grid Array (EBGA) package and is located on the system board just underneath the AGP connector. It provides the interface between the PCI bridge (PCI Rev. 2.2 compliant with support for 32-bit 33 MHz PCI operations), PCI-to-LPC (Low Pin Count) bridge, IDE controller, USB controller, SMBus controller and Audio Codec ’97 controller.

The ICH2 functions and capabilities are discussed in detail later on in this section. The following figure shows an example of the system block diagram using the ICH2.

ICH2 Architecture

ICH2 PCI Bus Interface

SMBus Controller

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.

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

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.

for ICH2 interrupts.

Low Pin Count Interface

Enhanced USB Controller

Refer to page 47 for information on the MaxiLife ASIC.

The ICH2 implements the LPC interface 1.0 specification.

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.

AC’97 Controller

IDE Controller

DMA Controller

This is the single-chip CS4299 audio controller that provides full audio features for the Kayak XU700.

Refer to page 46

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.

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 seven DMA channels can be programmed to support fast Type-F transfers.

for allocated DMA channel allocations). Any two of the

Interrupt Controller

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.

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.

Timer/Counter Block

Advanced Programmable Interrupt Controller

Real Time Clock

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.

Incorporated in the ICH2, the APIC can be used in either single-processor or multi-processor systems, while the standard interrupt controller supports only single-processor systems.

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.

The SMBus is a subset of the I2C bus. It is a two-wired serial bus which runs at a maximum speed of 100 kHz. It is used to monitor some of the hardware functions of the system board (such as voltage levels, temperature, fan speed, memory presence and type), both at system boot and during normal run-time. It is controlled by the SMBus controller located in the ICH2.

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.

Each DIMM socket is connected to the SMBus. The 168-pin DIMM modules include a 256 byte I 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.

Serial EEPROM

LM75 Temperature Sensor

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.

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 I

C 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 I

C 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 I via the ICH2. Its I

C cell may operate either in Slave or Master mode,

C bus),

switched by firmware, or automatically in the event of ‘Arbitration’ loss.

Test Sequence and Error Messages

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.

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.

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

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.

Processor Clock

Bus Frequencies

Voltage Regulation Module (VRM)

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).

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.

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.

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

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 asso-

ciative.

A 256KB L2 cache. The L2 cache is 8-way associative.

(APIC

modes)

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.

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 interrupts.

SCSI Adapter Cards

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.

onnector

Connector

Here is a description of connectors one through four.

Connector 1 68-pin external connector for LVD SCSI devices

Connector 2 68-pin internal connector for LVD SCSI devices

Connector 3 68-pin internal connector for Wide SE SCSI devices

Connector 4 50-pin internal connector for Narrow SE SCSI devices

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

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 Description

Double Transition Clocking

Cyclical Redundancy Check

Domain Validation Tests networks, cables, backplanes, terminators,

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.

Provides extra data protection for marginal cables that are connected to external devices. The Ultra3 SCSI cyclical redundancy check detects all:

• Single error bits

• Double bit errors

• Odd number of errors

• Burst errors up to 32-bits long

and hard disk drives to ensure that the 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

If for some reason the BIOS is corrupted and the standard flash cannot be used, use the BIOS Recovery Mode (exceptional BIOS recovery operation) to restore the BIOS. To do this:

Obtain a bootable DOS floppy disk.

Copy the BIOS files on to the floppy disk.

How to download the system BIOS is described on page 87 Create (or edit) the file, AUTOEXEC.BAT

This should contain a single line of text: “

phlash /c /mode=3 /s IX.W1.XX.FUL

” (rename the BIOS filename with the one on the floppy disk). Shut down the PC Workstation.

Power off the PC Workstation and remove the power cord.

Remove the cover.

Set switch 7 to the ON position.

Insert the floppy disk into the floppy disk drive.

Reconnect the power cord and switch on the PC Workstation.

The PC Workstation boots from the floppy disk, then flashes the BIOS.

However, it should be noted, that during the flash process, the screen remains blank. The recovery process is finished when there is one very long beep.

Power off the PC Workstation. Remove the floppy disk from the drive.

Remove the power cord. Set switch 7 back to the OFF position.

Replace the cover, reconnect the power cord, then reboot the PC

Workstation.

HP I/O Port Map (I/O Addresses Used by the System1)

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).

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 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.

Presence of processor, or

MaxiLife Test Sequence and Error Messages

Post Test Sequence and Post Error

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 status panel.
