An attempt to draw too much current (such as a short circuit across edgeconnector pins, or an accessory board that is not suitable for this PC Workstation), will cause the overload protection in the power supply to be triggered, and will shut down the PC Workstation.

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 following 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 (shown in the Environmental Specifications table) are valid for a standard configuration as shipped (one processor, 256 MB of memory, 300 W power supply, one hard disk drive, video card, LAN card).

Universal AGP Pro Slot

The Universal AGP Pro (Accelerated Graphics Port) bus, provides a high-performance graphics interface. It uses a 66.6 MHz base clock, and provides a peak bandwidth of 1064 MB/second in AGP 4x mode.

The Universal AGP Pro slot is a Universal-type connector which provides power through 3.3 V, 12 V or 5 V power rails with a maximum allocated power consumption of 50 W.

The Universal AGP Pro slot supports AGP 1x and 2x modes (uses 3.3 V or

1.5 V signals), and AGP 4x mode (1.5 V signalling is required).

2 System Board

Accessory Card Slots

AGP 4x mode transfers data at twice the speed of AGP 2x mode, which is itself twice the speed of the basic AGP 1x mode. This is achieved by multiplying the 66 MHz AGP clock frequency, so that four packets of data are transferred on each cycle (transfers on both rising and falling edges of the clock speed). Each packet of data contains four bytes, giving a transfer rate of 66.6 MHz x 4 (quad-clock mechanism) x 4 bytes, a maximum bandwidth of 1064 MB/s.

The AGP interface and bus are explained on page 38

PCI Slots

There is a total of five Peripheral Component Interconnect (PCI) connectors

on the system board:

• Three 32-bit 33 MHz PCI slots: 1, 2 and 5.

• Two 64-bit 66 MHz PCI slots: 3 and 4.

The three 32-bit/33 MHz PCI slots accept 5 V PCI cards and Universal PCI cards (support for 3.3 V or 5 V), while the two 64-bit/66 MHz PCI slots support 3.3 V PCI cards and Universal PCI cards (support for 3.3 V or 5 V).

A universal compatible 32-bit 33 MHz accessory card can also be installed in PCI slots 3 or 4. However in this case the PCI 64-bit bus will only perform at 33 MHz.

The maximum supported power consumption per slot is 25W, from the 5V and/or the 3.3V supply, and must respect the electrical specifications of the PCI 2.2 specification. 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.

If a standard AGP (Accelerated Graphics Port) card is installed in the AGP Pro slot, the maximum power consumption for the PCI accessory and AGP slot must not exceed 100 W.

2 System Board

Accessory Card Slots

If an AGP Pro card (>25 W and ≤50 W) is installed, then the PCI slot 1 is

made inaccessible as defined in the AGP Pro specification (PCI slot must be left unoccupied to provide its sources, in terms of cooling and electrical power, to the AGP Pro card. The following table shows the various PCI board installations for the different PCI slots:

A 64-bit card can be installed in a 32-bit slot. However, this card will only operate in 32-bit mode.

A 66 Mhz card can be installed in a 33 MHz slot. However, this card will only operate in 33 MHz mode.

A 33 MHz card can be installed in a 66 MHz slot, However, the card will operate in 33 MHz mode and will force all other PCI devices to operate at 33 MHz as well.

A 32-bit card can be installed in a 64-bit slot without preventing other 64-bit PCI devices to operate in 64-bit mode.

MCH Interface

The MCH interface provides bus control signals and address paths via the Hub Link 8-bit access to the ICH and via the Hub Link 16-bit access to the P64H for transfers between the processor(s) on the Host bus (FSB), Dual Rambus bus and AGP 4x bus.

The MCH supports 36-bit host addresses, allowing the processor to address a space of 64 GB. It also provides an 8-deep In-Order Queue supporting up to eight outstanding transaction requests on the host bus.

Host-initiated input/output signals are positively decoded to AGP, Hub Link 16-bit interface, or MCH configuration space and subtractively decoded to Hub Link 8-bit interface. Host-initiated memory cycles are positively decoded to AGP, Hub Link 16-bit interface, or DRAM, 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 Host 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 either Hub Link interface (8-bit or 16-bit) to DRAM do require a snoop cycle on the Host bus.

Memory access whose addresses are within the AGP aperture are translated using the AGP address translation table, regardless of the originating interface.

2 System Board

Memory Controller Hub (8240)

Write accesses from Hub Link interface (8-bit or 16-bit) to the AGP are supported.

The MCH can support one or two Pentium III processors, at FSB frequencies of 100/133 MHz using GTL+ signalling. Refer to page 64

for a description of

the Host 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 Host 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, 3.3 V,

266 MB/s peak transfer rate.

• AGP 1X with pipelining, sideband addressing can be added: uses 66 MHz,

32-bit, 3.3 V, increased bus efficiency, 266 MB/s peak transfer rate.

• AGP 2X with pipelining, sideband addressing can be added: 66 MHz

double clocked, 32-bit, 3.3 V, 533 MB/s peak transfer rate.

• AGP 4X with pipelining, sideband addressing can be added: 133 MHz

double clocked, 32-bit, 1.5 V, increased bus efficiency, 1066 MB/s peak transfer rate

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 Host bus error checking for data, address, request and response signals. Only 300 MHz and 400 MHz Direct Rambus devices are supported in any of 64, 128 or 256 Mb technology. 64 and 128 MBit RDRAMs use page sizes of 1 kbytes, while 256 Mb devices target 1 kbyte or 2 kbyte pages.

A maximum number of 64 Rambus devices (32 devices maximum per channel) is supported. Both channels must be populated with paired memory modules.

2 System Board

Memory Controller Hub (8240)

The following table shows the number of Rambus devices and memory technology available on a memory module.

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.

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 transaction.

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 Memory Expansion Card Connector 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 (individual chips) or one MRH-S (Memory Repeater Hub) per channel for DIMM sockets. The maximum available data bandwidth is

3.2 GB/s at 400 MHz.

The configuration of both primary rambus channels must be symmetrical. That is to say, whatever the configuration on channel A, the same must be on channel B.

2 System Board

Memory Controller Hub (8240)

Memory Expansion Card Connector

The actual memory array is on a Memory Expansion Card installed in a Memory Expansion Card Connector (MECC) located on the system board.

On the HP Kayak XU800 PC Workstation there are two types of Memory Expansion Cards supporting the following configurations:

Four-RIMM Memory Expansion Card

Four RIMM sockets support RDRAM ECC and memory modules installed in pairs. Any unused RIMM sockets must contain a continuity module.

RIMM SOCKET A0

RIMM SOCKET A1

Each DIMM socket is connected to the SMBus and is described on page 57

2 System Board

Memory Controller Hub (8240)

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 host interface at 100 MHz or 133 MHz, 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).

I/O APIC I/O APIC is used to support dual processors as well as enhanced interrupt

processing in the single processor environment. The I/O APIC controller of the ICH is used in conjunction with a second I/O APIC controller in the P64H.

2 System Board

PCI 64-bit Hub

The P64H is a peripheral chip that performs PCI bridging functions between the MCH and the PCI 64-bit 66 MHz bus. The P64H has a 16-bit primary hub interface to the MCH and a secondary 64-bit PCI bus interface. This controller inter-operates transparently with either 64-bit or 32-bit devices.

The following figure shows how the P64H chip is connected to the MCH via

the Hub Link 16 and to the supported devices such as those in the two PCI 64-bit 66 MHz PCI slots and AIC-7892 Ultra 160 SCSI controller via the PCI 64-bit 66 MHz bus.

Devices Supported on the PCI 64-bit 66 MHz Bus

The following devices are supported on the PCI 64-bit 66 MHz bus.

PCI 64-bit 66 MHz Slots There are two PCI 64-bit 66 MHz PCI slots (slots 4 and 5) connected to the

PCI 64-bit 66 MHz bus. These two 64-bit/66 MHz PCI slots support 3.3 V PCI cards and Universal PCI cards (support for 3.3 V or 5 V).

A universal compatible 32-bit 33 MHz accessory card can also be installed in PCI slots 3 or 4. However in this case the PCI 64-bit bus will only perform at 33 MHz.

Ultra-Wide 160 SCSI Controller

PCI slots are explained in detail on page 31

The Adaptec AIC-7892 Ultra 160 SCSI PCI controller is integrated on the system board. Data is transferred at 160 MB/s on 16-bit wide, Low Voltage Differential (LVD) bus.

NOTE If an Ultra-wide, or older SCSI device is connected on the SCSI bus, all

Ultra 160 and Ultra 2 SCSI devices will automatically be switched to Ultrawide SCSI. In this case, the LVD bus works as a single-ended bus, and data will only be transferred at 40 MB/s.

The controller is fitted with a 16-bit SCSI flat cable with five connectors, plus a SCSI termination device on the system board; so a maximum of five internal SCSI internal devices are supported. Additional devices can be added outside the PC Workstation by connecting directly to the rear panel SCSI connector. The external connector allows up to ten external devices to be connected. This gives a maximum of 15 (internal + external) devices that can be connected.

The last connector on the SCSI cable is connected to the external SCSI connector on the rear chassis. The connector before this is connected to the onboard SCSI terminator (located behind the processor).

By default, the internal SCSI bus is configured to run in Ultra 160 SCSI mode (providing a maximum band-width of 160 MB/s). The user may configure the SCSI system using the SCSISelect utility, included in the system BIOS. Refer to page 99

for details about the SCSISelect utility. This utility is also

described in more detail in the SCSI User’s Guide.

The Adaptec AIC-7892 Ultra 160 SCSI PCI controller is BBS compliant, but does not support Hot Swap.

2 System Board

The Input/Output Controller Hub (82801AA)

ICH Architecture The ICH 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 ICH interface, and no longer on the PCI bus, the ICH architecture ensures that both the input/ output functions integrated into the ICH and the PCI peripherals obtain the bandwidth necessary for peak performance.

ICH PCI Bus Interface The ICH 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 six external PCI masters in addition to the ICH requests and AC’97 controller. 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 68

for ICH 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 55 for information on the MaxiLife ASIC.

for a description of the devices on the SMBus, or to page 58

Low Pin Count Interface The ICH 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 two stacked connectors on the back panel. These ports are built into the ICH, as standard USB ports.

The ICH 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 and Windows 98 operating systems provide support for the USB.

2 System Board

The Input/Output Controller Hub (82801AA)

AC’97 Controller This controller, even though available in the ICH, is not used. The HP Kayak

PC Workstation uses the dedicated dual chip PCI solution of the CS4280

audio controller and the CS4297 Codec Audio Codec ‘97 (AC’97).

Refer to page 54 solution.

for information about the CS4280 and CS4297 audio

IDE Controller The IDE controller is implemented as part of the ICH chip and has PCI-

Master capability. Two independent ATA/66 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 and Ultra-ATA/66).

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

for allocated DMA channel allocations). Any two of the

The ICH 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 ICH supports a serial interrupt scheme and also implements the I/O APIC controller. A table on page 68

shows how the master and slave controllers are connected.

2 System Board

The Input/Output Controller Hub (82801AA)

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 Interrupt Controller

Incorporated in the ICH, the APIC can be used in either single-processor or multi-processor systems, while the standard interrupt controller supports 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 ICH’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 ICH includes full support for the Advanced Configuration and Power Interface (ACPI) specifications.

Devices on the SMBus

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 ICH.

ICH SMBus Master Controller

The ICH provides a processor-to-SMBus controller. All access performed to the SMBus is done through the ICH 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 I

information, including the DRAM chips’ manufacturer name, DIMM speed rating, DIMM 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.

2 System Board

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 ICH. 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.

Refer to “MaxiLife Test Sequence and Error Messages” on page 107 for detailed information about the different test sequences and error messages

FirmWare Hub (82802AB)

The FWH (also known as flash memory) is connected to the LPC bus. It contains 4 Mbit (512 kB) of flash memory.

The hardware features of the FWH include: a Random Number Generator (RNG), five General Purpose Inputs (GPI), register-based block locking and hardware-based locking. An integrated combination of logic features and non-volatile memory enables better protection for the storage and update of system code and data, adds flexibility through additional GPIs, and allows for quicker introduction of security/manageability features.

The following table shows the available FWH features

2 System Board

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 ICH 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.

2 System Board

Host Bus

The Host bus of the Pentium III processors, also referred to as the FSB (Front Side Bus), is implemented in the GTL (Gunning Transceiver Logic)+ technology. This technology features open-drain signal drivers that are pulled-up to 1.5 V through resistors at bus extremities; these resistors also act as bus terminators, and are integrated in the processor.

If only one processor is installed, a terminating board must be installed in the second processor slot.

Connector

The control signals of the Host bus allow the implementation of a “split transaction” bus protocol. This allows the Pentium III 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

2 System Board

Host 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 eight transactions are allowed to be outstanding at any given time.

Intel Pentium III Processor

The Pentium III processor has several features that enhance performance:

• Dual Independent Bus architecture, (supporting level cache sizes of

i256 KB) plus a 64-bit system bus that enables multiple simultaneous transactions (refer to “split -transaction” above).

• MMX2 technology, which gives higher performance for media,

communications and 3D applications.

• Dynamic execution to speed up software performance.

• Internet Streaming SIMD Extensions for enhanced floating point and 3D

application performance.

• Processor Serial Number is an electronic number incorporated in the

processor. If enabled, the Processor Serial Number can serve as a means of identifying the system. By default, this option is set to Disabled in the Setup program.

• Uses multiple low-power states, such as AutoHALT, Stop-Grant, Sleep and

Deep Sleep to conserve power during idle times.

The Pentium III processor is packaged in a self-contained Single Edge Contact Cartridge (SECC-2) installed in a Slot 1 processor slot. The SECC-2 cartridge requires a 242-contact Slot 1 connector on the system board. It includes a processor core chip and GTL+ termination resistors.

There are two Slot 1 processor slots, along with one VRM (Voltage Regulation Module) socket. A single Pentium III processor for Slot 1 is powered through an onboard voltage regulator.

Optional Second Processor

Single processor models can be upgraded to a dual processor system by installing a second processor in the vacant slot. The second processor must be a Pentium III processor for Slot 1 of the same speed as the first. The VRM supplied with the processor accessory kit is installed in the vacant VRM slot. The second processor is powered through the VRM.

2 System Board

Host Bus

NOTE When upgrading a processor or installing a second processor, the processor

type and speed is automatically recognized by the BIOS. This means that no particular switch settings are required.

Upgrading a single processor to a dual processor system on Windows NT and Windows 2000 platforms is made easier with the HP DualExpress! application which is included in the HP processor application kit.

Installing a second processor is only advantageous when the software can make use of parallel activity. In particular, you need to be running a multithreaded operating system that supports multiprocessing (one that is SMP- ready), such as Windows NT. The Windows NT operating system makes the best use of the Pentium III 32-bit architecture (though other operating systems will also show some benefit if 32-bit application programs are run).

The two processors must have the same speed.

Configuring for Multi-Processing

HP Kayak XU800 PC Workstations support Symmetric Multi-Processing (SMP). When a second processor is added, it is automatically detected so there is no specific configuration required.

The “mono-processing” mode has been implemented in order to support operating systems that rely on the “legacy” interrupt controller 82C59 and are not aware of I/O APIC controller operation. Refer to page 68 details.

for further

Processor Clock The 100/133 MHz Host Bus clock is provided by a PLL. The processor core

clock is derived from the Host Bus by applying a “fix ratio”.

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.

2 System Board

Host Bus

Cache Memory

The cache memory is sealed within a single Pentium III package that contains the processor L1 and L2 cache.

The L1 cache memory has a total capacity of 32KB (16 KB data, 16 KB instructions). The L2 cache memory has a capacity of i256 KB, and is composed of four-way set-associative static RAM. Data is stored in lines of 32 bytes (256 bits). Thus two consecutive 128-bit transfers with the main memory are involved in each transaction.

TagRam and Burst-pipelined Synchronous Static RAM (BSRAM) memories

and are implemented on die. Transfer rates between the processor’s core and L2 cache are at full processor core clock frequency and scale with the processor core frequency. Both the TagRam and BSRAM receive clocked data directly from the processor’s core.

The amount of cache memory is set by Intel at the time of manufacture, and cannot be changed.

(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 ICH 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 ICH 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 68 interrupts.

Video Memory

The video memory, also known as SGRAM, is a local block of RAM for holding major data structures: Frame Buffer (double buffer), Z-Buffer and T-Buffer (Texture Buffer). The Frame Buffer holds one frame steady on the screen while the next one is being processed, while the Z-buffer stores depth information for each pixel.

HP BIOS

The Setup program and BIOS are summarized in the two sections of this chapter. The POST routines are described in the next chapter.

The BIOS is based on an AMIBIOS 4 M/bits flash parts, PCI 2.2 Specification, and RIMM or DIMM memory modules. Added to this, a New BIOS Architecture (NBA) has been implemented. The main principle of the NBA is that HP features are independent modules and run at defined moments in the boot process. They are installed as hooks, either in:

• Source code form, for small tasks, or before memory is available.

• Binary. As .COM files, for larger tasks once memory is available.

They both communicate with the BIOS through CMOS and memory tables providing information to the operating system through SMBIOS tables.

So, what are hooks? Hooks are architected points in the BIOS where specific code can be run. HP code is integrated, as mentioned above, in either source/object files, or as separate binaries.

HP/NBA BIOS Summary

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 following one, give 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 qXX.YM.mm, where:

• q is an optional letter indicating non-production status (removed at

release).

• XX is a two-letter code indicating the system (IA).

• Y is a one-digit code indicating the HP entity.

• M is the major BIOS version.

• mm is the minor BIOS version.

Using the HP Setup Program

To run the Setup program, press while the initial “Kayak” logo is displayed immediately after restarting the PC.

Alternatively, press to view the summary configuration screen. The summary screen will remain visible until a key is pressed.

The band along the top of the Setup screen offers the following menus: Main, Advanced, Security, Boot, Power and Exit. These are selected using the left and right arrow keys.

Main Menu

The Main Menu presents a list of fields, for example, “PnP Operating System” (selects whether the BIOS or Plug and Play operating system configures Plug and Play devices); “Reset Configuration Data”, “System Time”, “System Date”, “Key Click”, “Key auto-repeat speed” “Delay before auto-repeat” and Numlock at Power-on”. By default the “Reset Configuration Data” item is set to “No”. Selecting “Yes”, will clear the system configuration data.

Advanced Menu

The Advanced Menu does not have the same structure as the Main Menu and Power Menu. Instead of presenting a list of fields, it offers a list of sub-menus. The Advanced Menu contains the following sub-menus:

• Processors, Memory and Cache. Configures processor, CPU speed,

Processor Serial Number, memory controller and cache operations (error correction, shadowing and caching).

• Floppy Disk Drives. Enables or disables the on-board floppy disk

controller.

• IDE Devices. Configures IDE devices. Setting of IDE Primary and Master

slave devices, and IDE Secondary Master slave devices. To use both these channels, the Integrated BUS IDE adapter is set to

HP/NBA BIOS Summary

Boot Menu

The QuickBoot Mode option allows the system to skip certain tests while booting. This decreases the time needed to boot the system menu, you can also display the option ROM messages. Enabling this option is recommended when installing an accessory card. It can be disabled when accessory card installation has been completed.

If both AGP and PCI video cards are installed, use the setting to select which will be used as a boot display device. If only one video card is installed, the setting is not used.

Select the order of the devices from which you want the BIOS to attempt 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.

Power Menu

This menu allows you to set the standby delay and suspend delay. Standby mode slows down the processor, while the suspend mode saves a maximum of energy. Both these options are only available with Windows 95. For other operating systems, Windows 98 and Windows 2000, use the control panel for similar options

Adaptec SCSISelect Configuration Utility

The AIC-7892 BIOS includes the SCSISelect configuration utility, which allows you to view and change host adapter settings. SCSISelect also lists the SCSI IDs of devices on the host adapter, formats SCSI disk drives, and checks drives for defects.

Default Settings

The following tables show the default configuration settings that can be changed. The first table shows the global settings which impact the host adapter; the second table shows the boot device options which allow you to specify the boot device; the third table shows the different advance configuration options; and the fourth table shows the device settings which apply to individual devices.
