*Since 29 A at 5 V equates to 145 W, it follows that for every 1 A that is required from the 3.3V supply, it is necessasry to reduce the 29 A limit on the 5 V supply by 0.66 A. For example, 3A at 3.3 V plus a maximum of 27 A at 5 V, or 6 A at 3.3 V plus a maximum of 25 A at 5 V.

An attempt to draw too much current (such as a short circuit across edge-connector pins, or an accessory board that is not suitable for these PCs), will cause the overload protection in the power supply to be triggered, and the PC could fail to boot.

2 SYSTEM BOARD

The next chapter describes the video, disk and network devices which are supplied with the PC. This chapter describes the components of the system board. An overview of the system board is

first given. Then the components of the Processor-Local Bus, the PCI Bus and the ISA Bus are described in more detail.

PRINCIPAL COMPONENTS AND FEATURES

The system board contains the following components:

PGA ZIF sockets

Each processor is packaged in a 387-way board in a

zero-insertion-force

(ZIF)

socket

pin-grid-array

. The

HP Vectra XU 6/xxx PC

(PGA), which is seated on the system

has two such sockets: the top one is occupied by the Pentium Pro (P6) processor; the bottom one is empty, and can be filled with an optional second Pentium Pro processor. The

HP Vectra VT 6/xxx PC

has one socket,

occupied by the Pentium Pro processor, with no option for fitting a second Pentium Pro processor.

VRM sockets

voltage regulator module

The

(VRM) is capable of supplying a voltage of 1.5 V to 3.5 V. This voltage is selected automatically, and depends on the needs of each processor. For instance, the 150 MHz Pentium Pro requires 3.1 V, whilst the 200 MHz version requires 3.3 V. There are two VRM sockets on the

HP Vectra XU 6/xxx PC

HP Vectra VT 6/xxx PC

(one of which is already occupied), and one on the

Accessory Slots

There are three

accessory slots

on the PCI bus, two on the ISA bus, and one that lies on either bus. Thus there are four PCI accessory sockets, and three ISA bus accessory sockets. The top PCI bus slot is already occupied by the Matrox MGA Millennium video controller. On the

HP Vectra XU 6/xxx PC

, the second PCI slot is also already occupied, by the HP PCI Integrated

10/ 100 VG Interface. (These two boards are described in the next chapter).

System Board Switches

The first three of the

system board switches

set the configuration for the PC, as summarized in the table below. The next two set the frequency of the Processor-Local bus, and the last three the ratio of processor-frequency to Processor-Local-bus-frequency.

Wavetable Interface Connector

This is used when installing a Creative Labs wavetable accessory board that operates with the integrated SoundBlaster audio interface.

Main Memory Module Sockets

There are eight

main memory module sockets

already occupied by the pair of

double interline memory modules

, arranged in four banks(A to D). One bank is

(DIMMs) that contain the 16 MB

of memory that is fitted as standard on all models of the PC.

SCSI Controller and Connector

Ultra SCSI controller

, on PCI bus of the

HP Vectra XU 6/xxx PC

, supports

Fast-20 SCSI-2

Internal and external connectors are provided.

IDE Controller and Connector

The Enhanced IDE (EIDE) controller chip can be found next to the IDE connectors. Connected to the PCI bus, it has IDE-Master capability. It has two channels, each capable of supporting two devices: a primary channel (recommended for EIDE, or IDE, hard disk drives, using the grey connectors); a secondary channel (recommended for EIDE, or IDE, CD-ROM drives, using the red connectors).

Page 14

Ultra I/O Chip

The

Ultra I/O

chip is located just slightly above and to the right of the ISA slots. It is a combined controller on the ISA bus for the flexible disk drive connector, and for the one parallel and two serial communications ports.

Audio Chip

SoundBlaster 16

The

chip is located to the right of the Ultra I/O chip, near the bottom right hand

edge of the board. This provides the audio interface, and is driven from the ISA bus.

Chip-Set

Intel 82450KX chip-set

The

comprises eight chips. Six of them are concerned with controlling memory accesses, and are located below the memory module sockets. These are the four datapath units, the memory controller chip, and the Mem/PL bridge chip. They are described in the sub-section of this chapter entitled “Main Memory”. The remaining two chips are the PL/PCI bridge chip, which is described in the section entitled “Devices on the PCI Bus”, and the PCI/ISA bridge chip, which is described in the section entitled “Devices on the ISA Bus”.

Gold Capacitor

is provided instead of a battery, and can store enough energy to power the

CMOS configuration memory for over a week after the mains power has been disconnected.

Architectural View

The following block diagram gives an architectural view of the

HP VectraXU 6/150 PC

. The next section describes the devices on the system board which are associated with the Processor-Local (PL) bus. The section after describes the devices on the system board that are associated with the Peripheral Component Interconnect (PCI) bus. The final section describes the devices on the system board that are associated with the Industry Standard Architecture (ISA) bus.

Page 15

DEVICES ON THE PROCESSOR-LOCAL BUS

The following subsystems are associated with the Processor-Local bus:

• Intel Pentium Pro (P6) microprocessor

• cache memory

• optional second microprocessor (

• main memory.

HP Vectra XU 6/xxx PC

only)

INTEL PENTIUM PRO (P6) MICROPROCESSOR

Apart from the two levels of cache memory, contained within the processor’s single integrated package, the other new features of the Pentium Pro are:

• three-way super-scalar pipeline (versus two for the Pentium)

• five execution units (versus three for the Pentium)

• 12 stage super-pipeline (versus 5 stage pipeline for the Pentium)

• dynamic, out-of-order, speculative execution

• 16-state, dynamic multiple branch prediction

• split-transaction bus

• register renaming. Although it is not pin compatible with the Pentium, the Pentium Pro is backward code-compatible.

Software written for previous HP Vectra models will run on the Pentium Pro-based HP Vectras. However, only 32-bit programs execute faster. 16-bit programs might even only execute at the speed that would have been attained by an equivalent 80486-based system.

Page 16

Many techniques have been adopted to accelerate the throughput of the instruction-pipeline of the Pentium Pro over that of the Pentium. Firstly, it is

super-pipelined

: the individual operations of the Pentium pipeline have been broken down into many sub-operations, leading to a much longer pipeline of smaller operations. Secondly, it is

super-scalar

: the five execution units are completely independent; not only can they have instructions issued to them asynchronously of each other, but they can complete their execution asynchronously of each other, too.

Since instructions can complete asynchronously, it is possible for a simple instruction to complete before a complex one which precedes it. This is the first of two ways in which the Pentium Pro manifests

out-of-order instruction execution

speculative execution

feature: whilst a time-consuming instruction is still awaiting completion, the

. The second way follows as a direct result of the

processor gets on with executing instructions that were fetched after it, on the speculation that they will probably be needed next.

Related to this, the Pentium Pro incorporates an even more elaborate (and more accurate) 16-

dynamic branch prediction

state

mechanism than the one which is used on the Pentium. This allows the processor to speculate as to which instructions will be needed following a conditional branch, based on past behavior at the branch.

A module, known as the

re-order buffer

(ROB), handles the out-of-order completion of instructions, and the cases where speculative execution proves to have been wrong (a misprediction by the branch prediction unit, for example).

System Board Switch Speed Settings

Like the Pentium and 80486 DX2 processors, the Pentium Pro uses internal clock multiplication. For example, the Pentium Pro 150 MHz processor multiplies the 60 MHz system clock by 2.5. Switches 4 and 5 on the system board switch bank set the frequency of the Processor-Local bus. Switches 6, 7 and 8 set the clock multiplier ratio. The relationship of the switch settings to Processor-Local bus and processor frequencies is summarized in the following table:

Switch 4 Switch 5 Processor

Local Bus Frequency

Off Off 66 MHz Off Off Off 2 : 1 133 MHz* On Off 60 MHz On Off Off 2.5 : 1 150 MHz Off Off 66 MHz On Off Off 2.5 : 1 166 MHz On Off 60 MHz Off On Off 3 : 1 180 MHz Off Off 66 MHz Off On Off 3 : 1 200 MHz

*The 133 MHz PentiumPro processor is not supplied in any of the Vectra models. This information is provided for completeness only.

CACHE MEMORY

There are two integrated circuits sealed within a single Pentium Pro package. One of these contains the Level-2 (L2) cache memory chip; the other contains the processor, which includes two banks of Level-1 (L1) cache memory.

Each L1 cache memory has a capacity of 8 KB, and is set-associative. The L2 cache memory has a capacity 256 KB, and is four-way set-associative.

Data is stored in the cache memories in lines of 32-bytes (256 bits). This involves two consecutive transfers of 128-bits with the main memory.

The Pentium Pro processor guards against

cache coherency

problems by monitoring the accesses to the memory which are made by other PC devices (including DMA controllers, and a second processor, if installed) through a mechanism known as

. Associated with each cache cache line. The amount of cached memory is set by Intel, at the time of manufacture, so cannot be changed.

It is anticipated that Intel will offer new versions of the Pentium Pro (P6) processor with 512 KB of L2 cache memory. Upgrading the processor will then become possible as the means for changing the amount of cache memory.

Extending the amount of cache memory can never have a detrimental effect on the performance.

can

However, it

experience a law of diminishing returns, so that extending the cache memory does not have a cost-effective impact on the performance. Finding the correct amount to install is an empirical process, either by simulation, or by trial and error on the real hardware.

PROCESSOR-LOCAL BUS

The Processor-Local bus of the

HP Vectra XU 6/150 PC

and

HP Vectra VT 6/150 PC

is 64 bits wide, and is clocked at 60 MHz. Although carrying 64-bits of data, it is in fact composed of 141 signals. These are implemented using Intel’s GTL+ technology. To reduce voltage over- and under-shoots, the signals are clamped to a 0 to 1.5 voltage range (with 60 mA per signal), and are filtered to prevent the logic edges from becoming too steep (that is, there is a minimum constraint on the rise and fall times, as well as the usual maximum constraint).

The bus is implemented as a

split-transaction bus

. A device (such as the Pentium Pro processor) can send a request (such as asking for the contents of a given memory address) and, rather than waiting for the result, it can release the bus, to get on with other work. The target device then requests the bus 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.

OPTIONAL SECOND MICROPROCESSOR

The support of Intel's the integrated L2 cache (which dispenses with the need for a proprietary bus to communicate among processors) ideally suits the Pentium Pro for the construction of multiprocessor systems. As many as four of them can be directly connected together, without the need for extra glue logic. At present, however, the

Not all operating systems support a second processor. Of those that do, not all uses of them increase the performance. Installing a second processor is only advantageous when the software can make use of parallel activity. In particular, you need to be running a multi-threaded operating system that supports multiprocessing (one that is Solaris, OS/2 SMP and Windows NT. Of these, the Windows NT operating system makes best use of the Pentium Pro’s 32-bit architecture (though other operating systems will also show some benefit if 32-bit application programs are run).

MAIN MEMORY

The

DRAM. The modules are organized in pairs so that a request for a transaction to or from the L2 cache

memory will cause two consecutive blocks of 16 bytes (128 bits) to be accessed. Rather than accessing all 128 bits simultaneously, the 64-bit data bus is used more efficiently by two accesses, the first to one half of the memory bank (for example, A1/B1/C1/D1), the second to the other (for example, A2/B2/C2/D2).

Although each memory module stores a line of 64 bits of data (8 bytes), each ECC memory module of the

HP Vectra XU 6/xxx PC

bus. The extra bits are generated by the Mem/PL Bridge chip, and are used to implement the

correcting code

(ECC). A subsequent error in a memory bit can be corrected, by referring to these extra bits, and hence neither causes the data to be lost, nor corrupted, nor the computation to be aborted (as would have been the case with simple parity detection, as on the

Chip-Set Chips that are involved in Memory Access

The Mem/PL Bridge chip (OMC-DP) is an Intel 82452KX. It interfaces between the ProcessorLocal (PL) bus, whose datapath is 64-bits wide, and the Intel proprietary memory bus, whose datapath is 72-bits wide. During a memory-write operation, on the

HP Vectra XU 6/xxx PC

, the chip generates 8 ECC parity bits. During a memory-read operation, the chip regenerates the 64 data bits from the 72-bit bus, applying error correction when appropriate.

Each of the four datapath chips (the Memory Interface Chips, MIC) is an Intel S82451KX, and acts as a two-way switch, able to connect alternately to the A1,B1,C1,D1 side of the interlaced memory, or the A2,B2,C2,D2 side. Since only an 18-bit path can be handled, four units are needed. Datapath units 1, 2, 3 and 4, handle bits 0..17, 18..35, 36..53 and 54..71, respectively.

Finally, the memory controller chip (OMC-DC) is an Intel S82453KX. It is responsible for decoding the signals on the address and control paths from the Processor-Local (PL) bus, and for generating the appropriate control signals for the memory banks (such as RAS, CAS, WE# and the address lines).

Error Correcting Code Operation

The

can tolerate as many as one faulty memory bit per 64-bit line of instruction or data words. The erroneous bit is corrected (automatically and transparently) by the hardware. The computer program continues to execute as if no error had occurred.

If two, or more, bits are faulty within any given 64-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

SMALL COMPUTER SYSTEM INTERFACE (SCSI)

An Adaptec AIC-7880 controller is integrated on the implements Fast-20 SCSI-2 (also known as Ultra-SCSI). It attains data transfer rates up to 20 MB per second on 8-bit wide data, single-ended. It supports up to seven SCSI devices, with a choice of internal and external SCSI connectors. The external SCSI connector is on the rear panel.

An HP provided driver is required for the OS/2 2.11 and Windows NT operating systems; an HP provided driver is also recommended for the Windows 3.11, Windows 95 and OS/2 Warp Connect operating systems.

INTEGRATED DRIVE ELECTRONICS (IDE)

The CMD646 chip supports Enhanced IDE (EIDE) and Standard IDE. To use the Enhanced IDE features, though, hard disk drives must be compliant with Enhanced IDE.

Up to four IDE devices can be supported: two connected to the primary channel cable, and two to the secondary channel cable. With EIDE, it is possible to have a fast device, such as a hard disk drive, and a slow device, such as a CD-ROM, on the same channel without affecting the performance of the fast device. The BIOS automatically sends a command to auto-detect each drive, and thereby select, automatically, the fastest configuration that is supported by it. However, in general, the primary channel cable (the grey one) is recommended for hard disk drives, and the secondary channel cable (the red one) for CD-ROM drives.

Transfer Rates Versus Modes of Operation

Bytes per

Sector

512

The controller supports 32-bit Windows and DOS I/O transfers (many IDE controllers use Windows integral IDE driver which only supports 16-bit I/O transfers). It has PCI master capability, and supports programmed I/O (PIO) modes up to mode 4 and direct memory access (DMA) modes up to mode 2 (giving a cycle time of 120 ns, and a transfer rate of 16.7 MB per second, in both cases). The five PIO modes allow the following transfer rates:

Mode 0 1 2 3 4 Cycle time (ns) 600 383 240 180 120 Transfer rate (MBytes/s) 3.33 5.22 8.33 11.1 16.7

The three DMA modes allow the following transfer rates:

Mode 0 1 2 Cycle time (ns) 480 150 120 Transfer rate (MBytes/s) 4.2 13.3 16.7

Operated in SLAVE mode, the IDE controller saturates the PCI bus with transfers, thus limiting the actual achieved transfer rate to 4 or 5 MBytes per second. Operated in MASTER mode, though, the IDE controller is allowed to work autonomously of the CPU, and the full 16.7 MBytes per second transfer rate can be achieved, with less than 33% occupancy of the PCI bus (so allowing the CPU to get on with other work for more than 67% of the cycle times, whilst the IDE transfers are going on in parallel).

Disk Capacity Versus Modes of Addressing

The amount of addressable space on a hard disk drive is limited by three factors: the physical size of the hard disk, the addressing limit of the IDE hardware, and the addressing limit of the BIOS. The Extended-CHS addressing scheme allows larger disk capacities to be addressed than under CHS, by performing a translation (for example regrouping the sectors so that there are twice as

SYSTEM ROM

The System ROM consists of 256 KB of 200ns, Flash EEPROM, implemented within a single 256 K 5 8-bit ROM chip. This is a ROM that is returned to its unprogrammed state by the application of appropriate electrical signals to its pins, and hence 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,

Setup

the ISA and PCI initialization, the error messages). These are summarized in Chapters 4 and 5.

Updating the System ROM

The System ROM can be updated with the latest BIOS firmware. This can be ordered from HP or downloaded from one of HP’s online services. (For more information on HP’s online services, refer to the Hewlett-Packard Support and Information Services chapter in the User’s Guide that was supplied with the computer.)

The System ROM is updated by running the HP6Init utility (HP6INIT.EXE) which is supplied with BIOS upgrade. The procedure for doing this is given in the computer.

Do not switch off the computer until the system BIOS update procedure has completed, successfully or not, since 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.

Error Diagnostics and Suggested Corrective Actions

The programs and data in the system ROM are accompanied by a check-sum code. If any of the programs or data ever become corrupted, the check-sum will no-longer correspond with the contents of the ROM, and the appropriate part of the POST routine will attempt to report the error:

3 INTERFACE BOARDS AND MASS-STORAGE

DRIVES

This chapter describes the video, disk and network devices which are supplied with the PC. These include the Matrox MGA Millennium video

controller board, and the HP PCI Integrated 10/100 VG Interface. It also includes the hard disk drives, flexible disk drives and CD-ROM drives that are supplied with the PC.

Matrox MGA Millennium Video Controller Board All models are supplied with a Matrox MGA Millennium PCI video controller on a board fitted in a

PCI accessory slot. This controller has an MGA-2064W processor, 2 MB video memory installed on the board, a VESA feature connector, and a socket for either a video memory upgrade module or an MPEG upgrade module. The possible upgrades for this socket are the following:

Add on module HP Part Number Matrox Part Number

2 MB video memory module D3557A MGA-MIL/MOD2 6 MB video memory module not available MGA-MIL/MOD6 MPEG module not available MGA-MIL/Media-XL

The video RAM (also known as window RAM, or WRAM) is a local block of RAM for holding two major data structures: the double buffer (to hold one frame steady on the screen whilst the next one is being processed), and the Z-buffer (for storing depth information for each pixel). It is dual ported, so that it can be inputting and outputting simultaneously.

The controller uses the PCI bus for data transfers between the processor and the video subsystem, and has the following features:

• 100% compatible with IBM

• 64-bit video memory access

• Hardware acceleration of graphical user interface (GUI) operations

• Support for up to 8 MB Video RAM (Window RAM) at 60 ns

• Graphics resolutions of up to 1600 5 1200

• Integrated 24-bit, 175 MHz RAMDAC

• Pixel clock maximum frequency of 135 MHz

• Green PC power saving features

• Standard and Enhanced Video Graphics Array (VGA) modes

• DDC 2B compliant. Drivers are not integrated into any of the operating systems, so HP-provided drivers must be

installed.

BIOS

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 under "System ROM" in chapter 2.

There is BIOS support for ISA “Plug and Play” accessory board configuration. It includes support for Plug and Play 1.0A, IDE PIO mode 4, Startup center, flash memory, desktop management interface (DMI) and the data integrity features. It ensures PCI 2.0 compliance with PCI-to-PCI bridge support. The Fast-20 SCSI-2 BIOS is also integrated with the system BIOS.

I/O ADDRESSES USED BY THE SYSTEM*

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).

This section provides more details of how the BIOS uses the system board components mentioned in the I/O port list.

DMA Channel Controllers

Only “I/O-to-memory” and “memory-to-I/O” transfers are allowed.“I/O-to-I/O” and “memory-tomemory” transfers are disallowed by the hardware configuration.

The system controller supports seven DMA channels, each with a pageregister used to extend the addressing range of the channel to 16 MB. The following table summarizes how the DMA channels are allocated.

Interrupt Controllers

The system has two 8259A compatible interrupt controllers. They are arranged as a master interrupt controller and a slave that is cascaded through the master.

The following table shows how the master and slave controllers are connected. The Interrupt Requests (IRQ) are numbered sequentially, starting with the master controller, and followed by the slave.

• IRQ5 can be made available by disabling the parallel port 2.

• IRQ7 can be made available by disabling parallel ports 1 and 2.

• IRQ12 can be made available by disabling the mouse interrupt.

PCI Interrupt Request Lines

PCI devices generate interrupt requests using up to four PCI interrupt request lines (INTA#, INTB#, INTC#, and INTD#).

When a PCI device makes an interrupt request, the request is re-directed to the system interrupt controller. The interrupt request will be re-directed to one of the IRQ lines made available for PCI devices.

All PCI devices with interrupt transfer support will use and share INTA#.A PCI device supporting multiple functionalities may use several INT lines. These devices will require more than one system interrupt request line.

5 POWER-ON SELF-TEST ROUTINES

This chapter summarizes the Power-On Self-Test (POST) routines. The first section indicates the order in which the tests are conducted. The second section lists the error codes which can be reported, along with theirmeanings. The third section summarizes the suggested corrective action appropriate for each error code.

VIEWED ON THE SCREEN

Each time the PC is turned on, or a reset is performed, the Power-On Self-Test (POST, also referred to as the

HP System Hardware Test

functionality of the system components and initializes certain system parameters. It starts by displaying the initial “Vectra” screen. Although the POST routines are run as normal, their progress is not displayed (other than on the eight-stage graphics histogram underneath the “Vectra” label). If POST detects an error, the results are reported on a

View System Errors

screen.

During the POST, the BIOS and other ROM data is copied into high-speed

shadow RAM

, where it is addressed at the same physical location as the original ROM in a manner which is completely transparent to applications. This technique provides faster access to the system BIOS firmware.

If the POST is initiated by a soft reset [CTRL] [ALT] and [DELETE], the RAM tests are not executed and shadow RAM is not cleared. In all other respects, the POST executes in the same way following power-on or a soft reset.

The POST detects when a hard disk has been replaced, or if there have been changes in the size of the hard disk. However, it does not report an error.

The POST performs the tests in the order described here:

Hard Disk Drive Tests

Tests for proper operation of the hard disk controller. Test failure causes an error code to display. The test does not detect hard disk replacement or changes in the size of the hard disk.

System Configuration Tests

Initiation of the system generation (SYSGEN) process, which compares the configuration information stored in the CMOS memory with the actual system. If a discrepancy is found, an error code will be displayed.

Configures any Plug and Play device detected (either PCI or ISA):

• All PCI devices, and any ISA device necessary for loading

the operating system will be configured for use.

• Any ISA device that is not required for loading the operating

system, will be initialized (prepared for loading of a device driver), but not fully configured for use.

ERROR CODES

POST error codes are returned and, if possible, displayed when an error is detected during the execution of the power-on self-test procedures. As well as the four digit code number, the error message utility automatically displays an error diagnosis and suggestions for corrective action.

An exhaustive list of the error codes is given here, and a list of the suggested corrective actions is given in the next section. In order to use these lists, you need to find the appropriate four digit, hexadecimal, error code in the list below. These have been sorted into numerical order, to make it easy to find the appropriate entry. (In this, two dots are used to represent a range of values, such

Page 45

as “4..7”, which means “4 or 5 or 6 or 7”, and the letter “x” is used to mean “any hexadecimal digit,

0..F”). Underneath each error code, there is a short summary of the error diagnosis. In order to find the suggested corrective action (SCA), it is necessary to read the five-character

code that is given on the right of the error code. This SCA code can then be found in the list that is given in the next section of this chapter.

Not all of these error codes can be generated by the
