An attempt to draw too much current (such as a short circuit across edge­connector pins, or an accessory board that is not suitable for these PC Workstations), will cause the overload protection in the power supply to be triggered, and the PC Workstation could fail to boot.
Both power supplied on the desktop and minitower models are new compare to the ones used on previous platforms (Vectra VL 6/xxx and XA 6/ xxx). The difference is at the V standby level, which has been extended to deliver 300mA instead of 100mA. This extra current is required by the 100TX hardware layer so it can perform a remote power-on at reception of a magic frame. Using an older power supply for a repair will prevent a remote power-on at reception of a magic frame.

NOTE When the PC Workstation is turned off with the power button on the front
panel, the power consumption falls below 5 Watts, 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. You should be aware that the PC Workstation will lose its time settings within a few days if you unplug the PC, or switch off the PC Workstation at the power block.

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. In addition, it contains the IDE controller, USB controller and Power Management logic

The PAC Chip (440LX)

The PAC chip, called the Intel 440LX AGPset, is contained in a Ball Grid Array (BGA) package, giving a smaller footprint and higher reliability.
The PAC chip integrates a Host-to-PCI bridge, optimized DRAM controller and data path, and an Accelerated Graphics Port (AGP) interface. The AGP is a high performance, component level interconnect, targeted at 3D graphics applications.
PL Bus Interface The PAC chip monitors each cycle that is initiated by the processor, and
forwards those to the PCI bus that are not targeted at the local memory. It translates PL bus cycles into PCI bus cycles.
The chip can support one or two Pentium II processors, at up to 66 MHz FSB clock frequency. Refer to page 35 Processor-Local Bus.
for a description of the devices on the
PCI Bus Interface The PCI bus interface is PCI 2.1 compliant.
Sequential PL-to-PCI memory write cycles are translated into PCI zero wait state burst cycles. The maximum PCI burst transfer can be between 256 bytes and 4 KB. The chip supports advanced snooping for PCI master bursting, and provides a pre-fetch mechanism dedicated for IDE read.
The PCI arbiter supports PCI bus arbitration for up to six masters using a rotating priority mechanism. Its hidden arbitration scheme minimizes arbitration overhead. Additional logic on the PC Workstation extends the number of fully supported masters to seven (440LX master not counted). Refer to page 39

for a description of the devices on the Processor-Local Bus.

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. Each slot can host
a 168-pin unbuffered SDRAM module, running at 66MHz, for a total of up to 348 MB of dynamic random access memory (ECC SDRAM).
The memory bus is 72-bits wide, comprised of 64 bits of data and 8 bits of ECC. Refer to “Main Memory Bus” on page 38 memory.
, for more detail on the main
Read/Write Buffers The PAC chip 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 PAC chip operates the host interface at 66MHz, PCI at 33 MHz and AGP
at 66/133 MHz. Coupling between all interfaces and internal logic is done in a synchronous manner. The PAC chip is not designed to support host bus frequencies lower than 66 MHz. The clocking scheme uses an external clock synthesizer (which produces reference clocks for the host, AGP and PCI interfaces).

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.

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 of the devices on the PCI Bus.
for a description
ISA Bus Interface As well as accepting cycles from the PCI bus interface, and translating them
for the ISA bus, the ISA bus interface also requests the PCI master bridge to generate PCI cycles on behalf of a DMA or ISA master. The ISA bus interface contains a standard ISA bus controller and data buffering logic. It can directly support six ISA slots without external data or address buffering. Refer to page 45
for a description of the devices on the ISABus.
SMBus Controller The System Management (SM) bus is a two-wire serial bus provided by the
PIIX4 controller. It runs at a maximum of 16 kHz. The bus monitors some of the hardware functions of the main board, both during boot-up and run-time. All accesses to the SM bus are handled by the main processor, via the PIIX4 SM bus registers. Refer to page 43 (System Management) Bus.
for a description of the devices on the SM
IDE Controller The PCI master/slave IDE controller, supporting four devices, two on each of
two channels, is described on page 39
.
USB Controller The PCI USB (Universal Serial Bus) controller, supports two stacked USB
connectors on the back panel. These ports are built into the PIIX4 controller, as standard USB ports. The USB is described in detail on page 40
Ultra DMA Controller The seven channel DMA controller incorporates the functionality of two
82C37 DMA controllers. Channels 0 to 3 are for 8-bit DMA devices, while channels 5 to 7 are for 16-bit devices (see page 82 programmed for any of the four transfer modes: the three active modes (single, demand, block), can perform three different types of transfer: read, write and verify. The address generation circuitry supports a 24-bit address for DMA devices.

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. One of these contains the Level-2 (L2) cache memory chip; the other contains the processor, which itself includes two banks of Level-1 (L1) cache memory.
The L1 cache memory has a total capacity of 32KB (16 KB data, 16 KB instruction). The L2 cache memory has a capacity 512 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 for each transaction.
The amount of cache memory is set by Intel at the time of manufacture, so cannot be changed.

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.
The supported operating frequencies of the GTL+ bus are 60 MHz and 66 MHz. The width of the data bus is 64 bits, the width of the address is 32 bits.
The control signals of the PL bus allows the implementation of a “split - transaction” bus protocol. This allows the Pentium II processor to send its request (such as asking for the contents of a given memory address) and then to release the bus, rather than waiting for the result, thereby allowing to accept another request. The 440LX 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 II Microprocessor

The Pentium II processor has several high-performance features that enhance performance:
• Dual Independent Bus architecture, which combines a dedicated 64-bit L2 cache bus (supporting level cache sizes of 256K or 512K), plus a 64-bit system bus with ECC that enables multiple simultaneous transactions (re­fer to above “split -transaction”).
• Intel MMX technology, which gives higher performance for media, com­munications and 3D applications.
• Dynamic execution to speed up software performance.
The Pentium II processor and level-2 cache memory are packaged in a self­contained, pre-sealed module, installed in a socket on the 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.
Only upgrades, pin compatible with the original processor, manufactured by Intel, are supported.

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. Switches 3, 4 and 5 set the clock multiplier ratio.

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.
The slots can be filled in any order, but there is a performance advantage in filling the slots in the order A, B, C. Memory upgrades are available in single 32 MB, 64 MB or 128 MB ECC SDRAM modules. Note that replacement of the supplied memory module may be necessary to obtain the 384 MB maximum memory, unless the supplied module was 128 MB.
With non-ECC SDRAM memory modules, a maximum of 192 MB can be obtained. These memory modules can be either; 16 MB, 32 MB or 64 MB.
NOTE If ECC and non-ECC memory modules are both installed, ECC will be
invalidated for all memory modules.
Error Correcting Code Operation
The error correcting code (ECC) memory of the HP Kayak XA PC Workstation allows any single bit error that occurs in any 72-bit line of
memory (64 data bits plus 8 parity bits) to be corrected (automatically and transparently) by the PAC chip.
The ECC detects single and dual bit errors. It can correct single bit errors during SDRAM reads. The corrected data is transmitted to the requester (PCI or CPU) but not written back to the SDRAM. A double bit error would cause an NMI to be generated, and the PC Workstation to be halted.
If more bits are faulty within any given 72-bit line, the effect is the same as it would have been without error correction. The effect of executing a faulty instruction is always unpredictable, and might cause the program to ‘hang’. The effect of reading a faulty data word is often similarly unpredictable, but can sometimes be tolerated (for instance, it might merely appear as a corrupted pixel on a video display).

Integrated Drive Electronics (IDE)

The IDE controller is implemented as part of the PIIX4 chip (the PCI/ISA bridge). It is driven from the PCI bus, and has PCI-Master capability. It supports Enhanced IDE (EIDE) and Standard IDE. To use the Enhanced IDE features the drives must be compliant with Enhanced IDE.
The IDE controller supports two devices (one master and one slave) connected to a single channel. The channel is fitted with an IDE cable with two connectors.
39
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. It is accessed through the PCI bus, and provides support for the two stacked USB connectors on the back panel. Over-current detection and protection is provided, but shared between the two ports.
USB works only if the USB interface has been enabled within the HP Setup program. Currently, only the Microsoft Windows 95 and Windows NT operating systems provides support for the USB.
The Microsoft Supplement 2.1 software called (called
USBSupp.exe), which
provides support of the Universal Serial Bus, can be obtained from the Hewlett-Packard World Wide Web site (refer to “Access HP World Wide

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).
The AGP bus is based upon a 66 MHz, 32 Bit PCI bus architecture, to which several signal groups have been added. These additional signals allow to implement AGP specific control and transfer mechanisms, which are:
Pipelining and sideband addressing. These control mechanisms in­crease the bus efficiency compared to the PCI protocol.
Double clocking (2x mode). This is a transfer mechanism that doubles the peak transfer rate to 528 MB/s, as two 32 Bit words are transferred in each clock period (2 x 32
bits x 66 MHz).
AGP specific transactions always use pipelining. The other two mechanisms can combine independently to pipelining, which leads to these operating modes:
• FRAME based AGP. Only the PCI protocol is used: 66 MHz, 32 Bits, 3.3V, 264 MB/s peak transfer rate.
• 1 X AGP with pipelining, sideband addressing can be added: 66 MHz, 32 Bits, 3.3V, increased bus efficiency, 264 MB/s peak transfer rate.
• 2 X AGP with Pipelining, sideband addressing can be added: 66 MHz dou­ble clocked, 32 Bits, 3.3V, increased bus efficiency, 528 MB/s peak trans­fer rate.

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.

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 4 Kbit of Serial EEPROM implemented within a single 512 K 8-bit ROM chip. 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, non­volatile RAM. It is used for storing the tatoo string, the serial number, and the parameter settings for the Setup program.

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.

Main PLL

The registers of the main PLL are accessed through the SM bus. These registers control the PLL clock signal outputs and are write-only.
WARNING: Writing over the SM bus may be destructive to the PC Workstation, as it
allows to access information necessary to the System BIOS, without which the system will not run.

Flash EEPROM

The PC Workstation uses 256 KB of Flash EEPROM implemented using one 8-bit ROM chip. Flash EEPROM is ROM in which the whole memory can be returned to its unprogrammed state by the application of appropriate electrical signals to its pins. It can then be reprogrammed with the latest upgrade firmware.
The System ROM contains: the LAN boot firmware, and the system BIOS (including the boot code, the ISA and PCI initialization, the Setup program and the Power-On Self-Test routines, video BIOS, plus their error messages). These are summarized in Chapters 4 and 5.
The Flash EEPROMs on the HP Kayak XA PC Workstation implement a bootblock feature which allows recovery from a failed attempt at updating the System BIOS. The bootblock contains the minimum system BIOS information necessary to reprogram the Flash EEPROM.

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. However, it should be noted that during the recovery procedure, there is no image on the screen, nor access to the keyboard or mouse (only “vital” devices that are required to boot on the floppy are initialized). Follow these steps to recover the BIOS:
1 Ensure that you have created a DOS-bootable diskette. This floppy dis-
kette contains all the recovery and system BIOS programming software (phlash.exe, platform.bin and hblxxxyy.Ful). Include the flash command in the autoexec.bat, for example: phlash /mode=3 HC1xyyzz.Ful
H = HP Professional PC C = Kayak XA (Pentium II models) 1 = Kayak family x = major revision yy = minor revision zz = language
2 Turn off the computer. Set Switch 9 to the Closed position.
3 Insert the DOS-bootable diskette.
49
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. This can be downloaded from HP’s World Wide Web site:
http://www.hp.com/go/kayaksupport
To download a BIOS upgrade, connect to the HP Web site and follow the on­screen instructions to download the flash utility programs (
AUTOEXEC.BAT and PHLASH.EXE), the BIOS file (HC11xx.FUL), and a file
called
pfmhd106.bin, onto a bootable diskette.
FLASH.BAT,
Before updating the System ROM, it is necessary to disable the “PSWRD” switch on the system switches (SW-7), and to type in the System Administrator’s Password when starting up the computer. The PCI and PnP information is erased in the process.
Do not switch off the computer until the system BIOS update procedure has completed, successfully or not, otherwise irrecoverable damage to the ROM may be caused. While updating the flash ROM, the power supply switch and the reset button are disabled to prevent accidental interruption of the flash programming process.

Other ISA Accessory Devices

ISA accessory boards are for slow peripheral accessories. A diagram showing the ISA slots that are available for the desktop and minitower models is on page 27
.
Plug and Play All PCI accessory boards are Plug and Play, although not all ISA boards are.
Check the accessory board’s documentation if you are unsure.
In general, in a Plug and Play configuration, resources for an ISA board have to be reserved first (using the Setup utility) and then you can plug in your board.
The procedure for installing an ISA accessory board that is not Plug and Play is described in the User’s Guide that is supplied with the PC Workstation.
NOTE The Windows NT 4.0 operating system is not Plug and Play. Information
explained above is only applicable for Plug and Play operating systems (for example, Windows 95).

Connectors

The Video Electronics Standards Association (VESA) defines a standard video connector, variously known as the VESA feature connector, auxiliary connector, or pass-through connector. The graphics controller supports an input/output VESA feature connector. This connector (whose pin names are listed in a table on page 71
) is integrated on the system board, and is connected directly to the pixel data bus and the synchronization signals.

Video Memory

The HP Kayak Workstation PCs are supplied with 4 MB of video memory integrated on the system board (revision B). There is either, an on-board 4 MB video memory soldered onto the system board. Or, 2 MB of built-in video memory (revision A) and a 2 MB video memory module installed in the video memory upgrade socket, giving 4 MB in total.
The video RAM (also known as the frame buffer) is a local block of 50 ns EDO DRAM for holding both the on-screen surface (reflecting what is currently displayed on the screen), and the off-screen surface (video frame, fonts, double buffer).
The following diagrams show the position of the video memory module on the minitower and desktop computers.
The soldered video memory (revision B) is located in the same area on the system board as the video memory module.

The LAN adapter supports the following two standards: 100 VG-AnyLAN, 100 Mbits per second over 4-pair, category-3, unshielded twisted pair (UTP), voice grade (VG) cable (IEEE 802.12 standard for Ethernet); 10 BaseT, 10 Mbits per second, ISO 8802-3 (IEEE 802.3 standard). On the rear panel there is one RJ-45 unshielded-twisted-pair (UTP) connector. The 10BT/100TX LAN Features on page 62
are also valid for the 10 BT/100 TX
PCI LAN controller.

SCSI Interface

The Symbios Logic SYM5C875J PCI-SCSI I/O Processor chip connects directly the SCSI bus and generates timing and protocol in compliance with the SCSI standard.
The SCSI interface operates as 16-bit, synchronous or asynchronous, single­ended, and supports Ultra SCSI protocols and 16-bit arbitration. The interface is made through two (and only two) of the connectors J2, J3 and J4.
Connector Description Location
J2 Shielded 68-pin high density right-angle receptacle. Protrudes through the
rear panel bracket.

By default, the internal SCSI bus is configured to run in Ultra-SCSI mode (providing a maximum band-width of 40 MB/s. The user may configure the SCSI system using the SCSI Configuration Utility, included in the system BIOS. This utility is described in more detail on page 77
.
SCSI-configured-automatically (SCAM) support is provided at level 2, for Plug and Play. However, hot swap is not supported. The controller is BBS compliant.
External (8-bit) SCSI connector
The Ultra narrow 8-bit SCSI connector uses addresses ranging from 0 to 7. As with the 16-bit internal SCSI connector, the SCSI address 0 is used by the first SCSI hard disk drive and SCSI address 7 is reserved for the integrated SCSI controller (the default for wide and narrow SCSI devices).

10BT/100TX LAN Controller

10BT/100TX LAN Controller
Certain models of the HP Kayak XA PC Workstation are supplied only with a 10BT/100TX LAN adapter which supports the following standards: 100 Mbits per second over 2-pair, category-5, unshielded twisted pair (UTP), or shielded twisted pair (STP); 10 BaseT, 10 Mbits per second, ISO 8802-3 (IEEE 802.3 standard).
On the rear panel there is one RJ-45 connector. There is an LED which indicates the LAN connection status as follows:
• Off - when there is no Autonegotiation response (for example, when the LAN cable is not connected to the network HUB.
• Blinking - during Autonegotiation
• Green (ON) - the connection has passed the Autonegotiation and a link has been established between the LAN adapter and the network HUB/ Switch.
The LAN adapter contains a connector to which an internal LAN cable may be connected to the external start connector on the system board, necessary for the use of the Remote Power On feature, described in detail in the User’s Guide provided with the PC Workstation. The LAN adapter that uses the Remote Power On feature must be installed nearer the processors than any other supplementary LAN adapter card.

Remote Power On

Remote Power On (RPO) is available at 10 and 100 Mbits per second.
Vstandby requirements supporting RPO
The Vstandby requirements for HP network cards supporting RPO, is:
• A power supply able to deliver at least 250mA on Vstandby output. This is the case for all HP Kayak systems.
Optional Bootrom Socket It is possible to add a flash device on the network card socket with a specific
LAN bootrom code. This new bootrom code will be seen and mapped automatically by the system BIOS instead of the embedded version (system BIOS).
NOTE At the time this TRM was produced, there was no flashing tool available to
allow you to update the bootrom content in the flash on the LAN adapter. A flashing tool for any AMD based card may be available, but in order to use this tool on HP cards, only 29fxxx flash devices must be used. At present, no test
has been carried out using this tool on HP cards.
Flash / ROM Devices The 10BT/100TX card provides a PLCC 32-pin socket and any size of flash
device can be used up to 256KB§.

Installing Two LAN Remote Power On Cards
From a pure network standpoint, this is supported and both cards will be functional (for example, from the operating system, it will be possible to have two LAN cards up and running at the same time).
However, there are restrictions due to the remote manageability boot features implementation. To support these features, an internal cable is required between the LAN card and the system board. Only one card can be attached to this cable, therefore remote manageability features are supported only on one card.
The problem is that current BIOS and hardware implementation doesn’t allow to identify to which card the cable is attached and this may result in having none of the remote capabilities working properly. Also, remote boot can only work on one card.
Therefore, if a customer wants to use two HP LAN cards without using HP LAN enhanced features (Remote boot, Remote power on), then there is no problem. However, if there is a requirement to use the HP LAN enhanced features, then it is not possible, at the present time, to use the two LAN cards on one system.
Even though it is possible to install two LAN Remote Power On cards in the computer, only one card is seen by the operating system.

HP/Phoenix BIOS Summary

HP/Phoenix BIOS Summary
The System ROM contains the POST (power-on self-test) routines, and the BIOS: the System BIOS, video BIOS (for models with an integrated video controller), and low option ROM. This chapter, and 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 HC.11.xx. The procedure for updating the System ROM firmware is described on page 50
.

Using the HP Setup Program

Press , to run the Setup program, while the initial “Kayak” logo is being displayed immediately after restarting the PC.
Alternatively, press to view the summary configuration screen. By default, this remains on the screen for 20 seconds, but by pressing once, it can be held on the screen indefinitely until is pressed again. Pressing
will cause the computer to be turned off.
The band along the top of the Setup screen offers five menus: Main, Advanced, Security, Boot, Power and Exit. These are selected using the left and right arrow keys. For a more complete description, see the User’s Guide that was supplied with the PC Workstation.
Main Menu
The Main Menu presents a list of fields, such as “System Time” and “Key Click”.
74
4 HP BIOS
HP/Phoenix BIOS Summary
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:
Memory and Cache. Define how to configure the specified block of
memory.
Video. Set the best ergonomic refresh rate supported by the display. This
feature, can also be used to set the preferred refresh rate for each graphic mode.
Flexible Disk Drives. Enable or disable the on-board flexible disk
controller.
IDE Devices. Configure IDE Primary and Secondary devices.
SCSI Interface. Enable or disable the integrated SCSI interface. In the
Ultra SCSI item, the Auto option will enable or disable automatically the Ultra SCSI by the BIOS, depending on whether external SCSI devices are detected or not.
Integrated Network Interface. Enable or disable the integrated network
interface. This feature must be enabled when an ethernet card is installed.
Integrated Peripherals. Enable or disable the on-board parallel and
serial ports at the specified address.
Integrated USB Interface. Enable or disable the integrated USB
(Universal Serial Bus) interface.
Integrated Audio Interface. Enable or disable the audio interface. This
feature is useful on non plug-and-play operating systems, because the integrated audio chip is plug-and-play.
PCI Devices. Enable this option if you need the BIOS to set the PCI Bus
Master bit. This could be necessary for some older PCI accessory boards.
ISA Resource Exclusion. reserves interrupts for legacy ISA devices to
prevent conflict with PCI/PnP devices.

HP/Phoenix BIOS Summary
Security
Sub-menus are presented for changing the characteristic and values of the System Administrator Password, User Password, Hardware Protection and Boot Device Security, the amount of protection against the system’s drives and network connections, and the amount of protection against being able to boot from the system’s drives and network connections. The Security Menu contains the following sub-menus:
User Password. This password can only be set when an administrator password has been set. The User Password prevents unauthorized use of the computer, protects stored data.
Administrator Password. This password prevents unauthorized access to the computer’s configuration. It can also be used to start the computer.
Hardware Protection. The following devices can have their accesses unlocked/locked: Integrated Flexible Disk Controller, Integrated ICD Controller, Integrated Data Communications Ports and Integrated Interfaces.
Boot Device Security. Select which devices are to be used for booting up the system. The option Disabled prevents unauthorized use of a device to start the computer.
Boot Menu
Select the order of the devices from which the BIOS attempts 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.
The QuickBoot Mode option allows the system to skip certain tests while booting. This decreases the time needed to boot the system
.
Power Menu
This menu allows you to set the standby delay. It also allows the system administrator to decide whether the mouse is enabled as a means of reactivating the system from Standby. It is also possible to specify whether the space-bar is enabled as a means of reactivating the system from Off.

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).
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 I/O addresses are allocated dynamically.

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.
85
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.
If the POST detects an error, the 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 (see
page 93
for a brief summary). Error codes are no longer displayed.
An example of an Error Code Message
Devices, such as memory and newly installed hard disks, are configured automatically. The user is not requested to confirm the change. Newly removed hard disks are detected, and the user is prompted to confirm the new configuration by pressing . Note, though, that the POST does not detect when a hard disk drive has been otherwise changed.
During the POST, the BIOS and other ROM data is 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.
This example explains the different coding messages that appear in the lower left corner of the screen when the POST detects an error during startup.
For example, if the error 0101 - 52 is displayed.
0101 - Post Error Code failure. This error code is accompanied by short
message. For this example, the message “keyboard error” is displayed. A table listing the error codes, causes and symptoms is on page 94
52 - Post Checkpoint Code. This checkpoint code indicates that a test has
failed at this stage of the POST. A table listing the error codes, causes and symptoms is on page 87

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.
Category #1: if the error requires to run Setup, the POST should prompt:
<F1= Continue>, <F2= Setup>, <Enter= View System Error>
and pause. (refer to autoconfig specification for more details on POST prompts)
Category
Category
“If errors are reported because one or more of the listed components have been removed, press <F4> to validate the changes.”
<F1= Continue>, <F2= Setup>, <F4= Validate Change>, <Enter= View System Error>
Category
#2: if the error is only a warning (i.e. key stuck), the POST should prompt:
<Enter= View System Error>
for 2 seconds then boot. (refer to autoconfig specification for more details on POST prompts)
#3: if the error is because a device has been unplugged or removed, the POST should prompt :
and pause. (refer to autoconfig specification for more details on POST prompts)
#4: if the error is serious, the POST should prompt:
The BIOS has detected a serious problem that prevents your PC from booting.”
<F2= Setup>, <Enter= View System Error>
and stop. Only the setup and the EMU can be run. The BIOS must never boot on HDD.

For example, “2C 0002” means address 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.

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. Check that the processor is correctly seated in its socket, and that the memory DIMMS and accessory cards are properly installed.

NOTE An 8 x 14 font for the EGA modes can be provided with a DOS TSR
(terminate and stay resident) program. If the TSR has not been loaded when the mode is set, the 8 x 16 font is used with the two bottom rows deleted. This causes truncation of characters with descenders, but does not restrict program operation. The TSR should be used for absolute compatibility with DOS applications that use the 8 x 14 font.
