1 System Overview Documentation Where to Find the Information The following table summarizes the availability of information within the HP Vectra VL and XA 5/xxx PC documentation set.
2 System Board The next chapter describes the video, disk, audio and network devices which are supplied with the various models of the computer. This chapter describes the components of the system board, taking in turn the components of the Processor-Local Bus, the Peripheral Component Interconnect (PCI) bus and the Industry Standard Architecture (ISA) bus.
2 System Board System Board System Board HP ASIC 210 mm Only on some VL models 280 mm The video memory, video memory upgrade sockets, graphics controller and display connector are not loaded on any models that are supplied with a Matrox MGA Millennium board in a PCI accessories slot. This includes all models of the HP Vectra XA 5/xxx PC (desktop and minitower), and some models of the HP Vectra VL 5/xxx Series 5 PC (desktop and minitower).
2 System Board Architectural View Architectural View Processor-Local Bus (64 bit, 60/66 MHz) ISA Bus (16 bit, 7.5/8.
2 System Board Chip-Set Chip-Set The chip-set comprises three chips. These interface between the three main buses (the Processor-Local bus, the PCI bus and the ISA bus). • The TXC chip (82439HX) is a combined PL/PCI bridge and cache controller and main memory controller and PCI-to-PL bus data path. • The PIIX3 chip (82371SB) is a combined PCI/ISA bridge and IDE controller and USB controller.
2 System Board Chip-Set PCI Bus Interface Sequential PL-to-PCI memory write cycles are translated into PCI zero wait state burst cycles. The maximum PCI burst transfer can be from 256 bytes to 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 four masters using a rotating priority mechanism. Its hidden arbitration scheme minimizes arbitration overhead.
2 System Board Chip-Set accesses to related addresses, they do not need four independent accesses to main memory, but can be organized as a pipelined burst. The second, third and fourth cycles in each burst require less time to complete than the first. This is because the first cycle includes the addressing phase and memory pre-charge timing. The read and write access timing has the pattern 3-1-1-1.
2 System Board Chip-Set PCI/ISA Bridge Chip (82371SB) This chip is encapsulated in a 208 pin plastic quad flat pack (PQFP) package. PCI Bus Interface This part of the chip performs PCI-to-ISA, and ISA-to-PCI bus cycle translation. It supports the Plug-and-Play mechanism. 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.
2 System Board Chip-Set Super I/O Chip (37C932) The Super I/O chip (FDC37C932) is contained within a 160-pin PQFP package. The chip provides the control for the following devices.
2 System Board Chip-Set described on page 37. RTC The real-time clock (RTC) is 146818A-compatible. With an accuracy of 20 ppm (parts per million). The configuration RAM is implemented as 256 bytes of CMOS memory. Serial EEPROM This is the non-volatile memory which holds the default values for the CMOS memory (in the event of battery failure, or the user pressing in Setup). General Purpose I/O There are several general purpose I/O pins.

2 System Board Devices on the Processor-Local Bus Devices on the Processor-Local Bus The Intel Pentium Microprocessor The Pentium processor is packaged in a pin-grid-array (PGA), and is seated on the system board in a zero-insertion-force (ZIF) socket 7. Only upgrades that are pin compatible with the original processor, manufactured by Intel, are supported. P54CS chips working at 133 and 150 MHz (along with P54C chips working at 75, 90, 100 MHz and new versions of the 120 MHz chip) require a 3.3 V supply.
2 System Board Devices on the Processor-Local Bus Bus Frequencies The location of the system board switches is shown in the diagram on page 20. Five of these switches (SW-1,2,3,4 and 7) determine the working frequencies of the PC, and the three frequency multipliers (M1, M2 and M3), as summarized in the table below. The uses of the other switches are summarized on page 39. There is a 14.
2 System Board Devices on the Processor-Local Bus Setting the switches to operate at a slower speed, than the processor is capable of supporting, can still cause erratic behavior in some case, and would reduce the instruction throughput in others. Cache Memory The computer supports two levels of cache memory, each with a 32-byte line width. The Level-1 (L1) cache memory is fabricated on the processor chip. The Level-2 (L2) cache memory is a slower module on the system board.
2 System Board Devices on the Processor-Local Bus Each bank that is used must contain a pair of identical modules: the same speed (60 or 70 ns), the same width (32-bit or 36-bit), and the same technology (extended data out, EDO, or fast page mode, FPM). Different banks can contain different speed modules (but the computer will work at the speed of the slowest bank).

2 System Board Devices on the PCI Bus to a channel, it should be in the master position (the connector that is closest to the system board, unless the markings on the cables state otherwise). 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 sends a command to each drive to determine, automatically, the fastest configuration that it supports.
2 System Board Devices on the PCI Bus Universal Serial Bus (USB) Controller When the HP Vectra VL 5/xxx Series 5 and XA 5/xxx PCs were first released, they were preloaded with the Microsoft Windows 95 operating system, version SR2. The Microsoft Supplement 2.1 software, which provides support of the Universal Serial Bus, was not available. When it becomes available, it can be obtained from the Hewlett-Packard World Wide Web site: http://www.hp.

The computer is supplied with a Logitech 2-button mouse, and a C3758A keyboard with the following features: ❒ Space bar power on, to start the computer from the Off state (if power on from keyboard is enabled in the Setup program).
2 System Board Devices on the ISA Bus Flash EEPROM (the System ROM) The computer uses 256 KB of Flash EEPROM implemented within a single 256 K ✕ 8-bit ROM chip (or in two 128 K ✕ 8-bit chips). 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 firmware.
2 System Board Devices on the ISA Bus System Board Switches Five of the system board switches (whose location is shown on page 20) set the working frequencies for the computer, as summarized on page 31. The others set the configuration for the computer, as summarized in the table on the next page.
2 System Board Devices on the ISA Bus Updating the BIOS Before Considering Replacing the System Board If the computer is faulty, but it starts up correctly, and the fault is not clearly due to the system board hardware, then it is advisable to check the BIOS version number. The BIOS version number can be found from the summary screen, or the Setup program, obtained by pressing or , respectively, when the computer has just been restarted, as described in Chapter 4.

4 Summary of the HP/Phoenix BIOS Setup Program Power Menu The “Power” menu allows the user to set the standby delay. It also allows the system administrator to decide whether the network, serial ports, mouse, or space bar are enabled as a means of reactivating the system from Standby or Suspend. It is also possible to specify whether the network is enabled as a means of reactivating the system from Off, using the remote power-on (RPO) facility (as described in the next section of this chapter).
4 Summary of the HP/Phoenix BIOS Power Saving and Ergonometry Power Saving and Ergonometry Power-On from Space-Bar The power-on from the space-bar function is enabled, provided that: • The computer is connected to a Windows 95 keyboard (recognizable by the Power-On icon on the space bar). • The computer is running the Windows 95 operating system. • The function has not been disabled by setting SW-9 to closed on the system board switches.
4 Summary of the HP/Phoenix BIOS Power Saving and Ergonometry The time-out period is the delay during which the power-down command can be cancelled (whilst the About to shut down Windows message is displayed on the screen). If the user cancels, the computer is returned to normal operation; otherwise, the computer goes on to check if there are any unsaved files.
4 Summary of the HP/Phoenix BIOS Power Saving and Ergonometry The network chip sends a signal over the External Start connector, where it is received by the special network remote power chip. This in turn switches on the main power supply. The PC starts normally from whatever operating system is installed, just as if the power supply had been switched on from the external power switch. The display does not itself need to have RPO.

4 Summary of the HP/Phoenix BIOS BIOS Addresses The PCI interrupt lines A, B, C and D are spread across the four inputs of the interrupt router (which is part of the PCI/ISA bridge, in the PIIX3 chip). Since most PCI devices are single-function, this allows for an even distribution of the lines. The distribution is shown in the following diagram.
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 with the initial “Vectra” logo when the PC is restarted.
5 Power-On Self-Test and Error Messages Order in Which the Tests are Performed Shadow the System ROM BIOS Load CMOS Memory CMOS RAM Test CPU Cache Memory Test Tests the system ROM BIOS and shadows it. Failure to shadow the ROM BIOS will cause an error code to display. The boot process will continue, but the system will execute from ROM. This test is not performed after a soft reset (using and Delete ). Checks the serial EEPROM and returns an error code if it has been corrupted.
5 Power-On Self-Test and Error Messages Order in Which the Tests are Performed Protected Mode RAM Test (Extended RAM) Tests protected RAM in 64 KB segments above 1 MB. (This test is not done during a reset using and Delete ). Test failure causes an error code to display. Keyboard / Mouse Tests Keyboard Test Mouse Test Network Test Invokes a built-in keyboard self-test of the keyboard’s microprocessor and tests for the presence of a keyboard and for stuck keyboard keys.
5 Power-On Self-Test and Error Messages Error Message Summary Error Message Summary The POST section of the HP BIOS no longer displays numeric error codes (such as 910B) but gives a self-explanatory, descriptive diagnosis, and a list of suggestions for corrective action. The following table summarizes the most significant of the problems that can be reported.
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. Beep codes are useful for identifying the error when the system is unable to display the error message. Beep Pattern - Beep Code1 Numeric Code 1 B4h This does not indicate an error. There is one short beep before system startup.
