2 System Board Chip-Set Chip-Set The Intel AGPset is comprised of two chips. The 440LX PAC chip and the PIIX4chip. • The PAC chip (440LX) is the bridge between four buses: the PL (GTL) bus, the main memory bus, the PCI bus and the AGP (graphic) bus. • The PIIX4 chip is the bridge between three buses: the PCI bus, the SM bus and the ISA bus.
2 System Board Chip-Set AGP Bus Interface A controller for the AGP (Accelerated Graphics Port) slot is integrated in the 440LX PAC chip. The PAC chip supports only a synchronous AGP interface, coupling to the host bus frequency. The AGP characteristics are described in detail in “Accelerated Graphics Port (AGP) Controller” on page 41. Main Memory Controller The main memory controller supports three DIMM slots.
2 System Board Chip-Set The PIIX4, PCI/ISA Bridge Chip (82371AB) The universal host controller interface (UHCI) chip, known as PIIX4, is encapsulated in a Ball Grid Array (BGA) package. The PIIX4 chip is a multi-function PCI device implementing a PCI-to-ISA bridge function, a PCI IDE function, a Universal Bus host/hub function, and an Enhanced Power Management function. The following figure shows an example of the system block diagram using the PIIX4 chip.
2 System Board Chip-Set PCI Bus Interface This part of the chip is responsible for transferring data between the PCI bus and the ISA expansion bus. It performs PCI-to-ISA, and ISA-to-PCI bus cycle translation. It supports the Plug-and-Play mechanism. Data buffers are provided, to isolate the PCI and ISA buses. Refer to page 39 for a description of the devices on the PCI Bus.
2 System Board Chip-Set and slave controllers are connected. Counter / Timer The chip contains a three-channel 82C54 counter/timer. The counters use a division of the 14.318 MHz OSC input as the clock source. Serial EEPROM This is the non-volatile memory which holds the values for the Setup program (they are no longer stored in the CMOS memory). The Serial EEPROM is described on page 43. Cache Memory There are two integrated circuits sealed within a single Pentium II package.
2 System Board Devices on the Processor-Local Bus Devices on the Processor-Local Bus The Processor-Local (PL) bus of the Pentium II processors, also referred to as their FSB (Front Side Bus), is implemented in the GTL+ technology. This technology features open-drain signal drivers that are pulled-up to 1.5 V through 56 ohm resistors on both ends of the bus; these resistors also act as bus terminators, and are integrated in the Pentium II processors.
2 System Board Devices on the Processor-Local Bus The heat-sink is supplied with the processor, and is bolted to it by the manufacturer. The module is held in place by a bracket. There are two plastic clips, one on the top of each pillar of the bracket, to hold the processor module in place. To remove the old processor module: 1 Press the two plastic clips towards each other. 2 Carefully pull the processor module away from its connector on the system board.
2 System Board Devices on the Processor-Local Bus Bus Frequencies There is a 14.318 MHz crystal oscillator on the system board. This frequency is multiplied to 66 MHz by a phase locked loop. This is further scaled by an internal clock multiplier within the processor. For example, the Pentium II 300 MHz processor multiplies the 66 MHz system clock by 4.5. Switches 1 and 2, on the system board switches, set the frequency of the Processor-Local bus, which for all HP Kayak XA PC Workstation models, is 66 MHz.
2 System Board Main Memory Bus Main Memory Bus The memory bus is 72-bits wide, comprised of 64 bits of data and 8 bits of ECC. It is connected to the Main Memory and to the PAC (440LX) chip. There are three 168-pin DIMM slots on the system board for installing main memory; slots A, B and C. All HP Kayak XA PC Workstation models are supplied with one memory module (either 16 MB, 32 MB or 64 MB ECC SDRAM) in one of the three slots, leaving the other slots free for memory upgrades.

2 System Board Devices on the PCI Bus It is possible to mix a fast and a slow device, such as a hard disk drive and a a CD-ROM, on the same channel without affecting the performance of the fast device. The BIOS determines automatically, the fastest configuration that each device supports. However, in general, the IDE cable is recommended for CD-ROM drives, and the SCSI cables for hard disk drives. Universal Serial Bus (USB) Controller The USB controller is implemented as part of the PIIX4 chip.
2 System Board Accelerated Graphics Port (AGP) Controller Accelerated Graphics Port (AGP) Controller The AGP technology was developed as a means to access system memory as a viable alternative to augmenting the memory of the graphics subsystem needed for high quality 3D graphics applications. All models of HP Kayak XA PC Workstations support an AGP (Accelerated Graphics Port) device (Laguna Graphic Controller from Cirrus).
2 System Board Accelerated Graphics Port (AGP) Controller AGP PCI Bus Implementation In the below diagram, the AGP Bus is viewed as a PCI bus with extra data lines.
2 System Board Devices on the SM Bus Devices on the SM Bus Device PIIX4 SM Bus Master Serial EEPROM SM Bus Address 10 A8, AA, AC, AE LM75 90 SDRAM slot 1 A0 SDRAM slot 2 A2 SDRAM slot 3 A4 PLL D2 The System Management (SM) bus is used to monitor several of the hardware functions (such as voltage levels, temperature, fan speed, DIMM presence and type) of the system board. It is controlled by the SM bus controller located in the PIIX4 chip.
2 System Board Devices on the SM Bus LM75 Chip The LM75 chip is a temperature sensor and alarm located on the system board. It is used to measure the temperature in one area of the PC Workstation, and to send an alarm to the processor in case of overheating. This chip includes a security mechanism which prevents the system fan from being disabled using software controls so long as the temperature measured by the sensor is above the maximum operating temperature.
2 System Board Devices on the ISA Bus Devices on the ISA Bus ISA Device Index Data Ultra I/O 2Eh 2Fh Little Ben (HP ASIC) 96h 97h The Super I/O Controller (NS 82317) The Ultra I/O chip (NS 82317) provides the control for two FDD devices, one serial port and one bidirectional multi-mode parallel port. Serial / parallel communications ports The 9-pin serial port (whose pin layouts are depicted on page 71) supports RS-232-C and are buffered by 16550A UARTs, with 16 Byte FIFOs.
2 System Board Devices on the ISA Bus Audio Controller The HP Kayak XA PC Workstation has an audio chip (AD1816) integrated on the system board. This single chip is a Plug and Play multimedia audio subsystem for concurrently processing multiple digital streams of 16-bit stereo audio. Host Interface The AD1816 audio chip contains all necessary ISA bus logic on chip.
2 System Board Devices on the ISA Bus Feature: Description: Microphone Input • Stereo Out Jack • • • 20 dB gain preamplifier. The boost can be muted with software 16-level programmable volume control Input impedance: 600 ohms Sensitivity: 30 mVpp to 200 mVpp • Impedance: 32 ohms The headphones jack and the stereo-out (audio) jack can be used interchangeably. The Windows 95 and Windows NT operating systems each have integrated drivers (Directions III).
2 System Board Devices on the ISA Bus System Board Switches The first two of the system board switches set the frequency of the Processor-Local bus, and the next three the ratio of processor-frequency to Processor-Local-bus-frequency, as summarized on page 37. The next five switches set the configuration for the PC Workstation, as summarized in the table below. Switch Switch Function Default 1 Open Reserved - Do not use (always set to Open). Open 2-5 - Bus Frequencies (see the table on page 37).
2 System Board Devices on the ISA Bus The following diagrams show the position of the system board switches on the desktop and minitower models. BIOS Update Crisis Recovery Procedure If, for example, during a BIOS update process, the procedure is interrupted by a power failure, and the system does not start, then you can still recover the situation of a destroyed system BIOS.
2 System Board Devices on the ISA Bus 4 Power on the computer. 5 During the recovery process, short beeps are emitted. The recover process is finished when there is a much longer beep (after approximately 1 to 2 minutes). 6 Power off the computer. Press the power ON/OFF button (for about 5 seconds), until the ON/OFF light switches off. Set the switch 9 to the Open position. Updating the system ROM The System ROM can be updated with the latest BIOS firmware.

3 Interface Devices and Mass-Storage Drives Cirrus 5465 Graphics Controller Chip Available Video Resolutions The number of colors supported is limited by the graphics device and the video memory. The resolution/color/refresh-rate combination is limited by a combination of the display driver, the graphics device, and the video memory. If the resolution/refresh-rate combination is set higher than the display can support, you risk damaging the display.
3 Interface Devices and Mass-Storage Drives SCSI / LAN Combo Board SCSI / LAN Combo Board Certain HP Kayak XA PC Workstations are supplied with an integrated SCSI / 10BT/100TX LAN combo board. Because the SCSI / LAN combo board includes two controllers, only one PCI slot is necessary for installing this board. The PCI and SCSI controllers access the PCI bus through a PCI bridge. The SCSI and PCI functionalities of the SYM8751SP are contained within the Symbios Logic SYM5C875J PCI-SCSI I/O Processor chip.

4 HP BIOS BIOS Addresses BIOS Addresses This section provides a summary of the main features of the HP system BIOS. This is software that provides an interface between the computer hardware and the operating system. The procedure for updating the System ROM firmware is described on page 50. System Memory Map Reserved memory used by accessory boards must be located in the area from C8000h to EFFFFh.
4 HP BIOS BIOS Addresses 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.

5 Power-On Self-Test and Error Messages This chapter describes 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.
5 Power-On Self-Test and Error Messages Order in Which the Tests are Performed Order in Which the 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 is restarted. If you wish to view the POST details, press to get the HP Summary Screen.

5 Power-On Self-Test and Error Messages Error Message Summary Error Message Summary The EMU utility (.COM application written in C language) is to provide full screen online help messages (localized) on most common POST errors. When an error is generated in POST during the boot process, EMU is run by typing ENTER. The entry point of each EMU message is a 4-digits error code generated by POST. If the POST reports an error, one of the following four error categories will be displayed.
5 Power-On Self-Test and Error Messages Error Message Summary The following table list the error codes, causes and symptoms and the accompanied short message that are displayed in the upper left corner of the screen.

5 Power-On Self-Test and Error Messages Beep Codes Beep Codes If a terminal error occurs during POST, the system issues a beep code before attempting to display the error in the upper left corner of the screen. Beep codes are useful for identifying the error when the system is unable to display the error message.
5 Power-On Self-Test and Error Messages Lights on the Hardware Control Panel Lights on the Hardware Control Panel When the computer is first powered on, the power-on light on the status panel illuminates yellow for about a second before changing to green. This change of color is caused by the execution of an instruction early in the System BIOS code. If the light remains at yellow, therefore, it indicates a failure of the processor or the System ROM in the instruction-fetch process.
