It is important to note the following information:

• There are no models fitted with second-level cache memory as standard.

• All models with 16 MB of main memory are pre-loaded with selectable Windows 95 or

Windows for Workgroups 3.11 software.

• HP does not recommend using Windows 95 on a PC with only 8 MB of main memory.

PRODUCT FEATURES

Overview

The HP Vectra VE 5/xx series 2 is a PENTIUM (P54) processor, ISA/PCI-based PC. The

system consists of a system board and a backplane.

• The desktop’s backplane has one PCI slot, one combination ISA/PCI slot, one ISA slot

and one HP proprietary ISA slot for accessory boards.

New Features

• A completely upgradable Pentium-based system board (using system board

switches and voltage regulator module).

• A new keyboard supporting Windows 95 special key functions.

• Vectra Ergonomic Power Solution (VEPS): space bar power-on (under any

operating system), push-button status panel, and software shutdown from

Windows 95.

• HP’s new style BIOS.

System Board

The main features of the system board are:

• A system board that can mount PENTIUM processors (with accompanying Voltage

Regulation Module) at several different clock speeds (75 MHz, 100 MHz and 133 MHz).

• A new type of main memory module called EDO (Extended Data Output) for faster

memory access times (60 ns).

• Optional 256KB of synchronous pipeline burst level 2 cache.

• A 64-bit host bus for PENTIUM processor, cache and main memory.

• A 32-bit Peripheral Component Interconnection (PCI) local bus for accessing the video

controller and IDE controller.

• An Industry-Standard Architecture (ISA) bus for ISA-compatible controllers (for devices

such as flexible disk drives, serial ports, parallel port, and audio card in multimedia

models).

• A dual password (administrator and user) security system that provides protection against

unauthorized use of the PC.

• A flash BIOS updating facility.

Microprocessor

The Pentium microprocessors used in the HP Vectra VE 5/xx series 2 use internal clock

multiplication, similar to that used by the 486 DX2 processor. The microprocessor’s internal

clock is a multiple of the system clock. The Pentium 75 MHz and 100 MHz processors multiply

the 50 MHz and 66 MHz system clock by a factor of 1.5. The Pentium 133 MHz processor

doubles the 66 MHz system clock. The Pentium 150 MHz processor multiplies the 60 MHz

system clock by a factor of 2.5. To set the appropriate switches for each processor speed,

refer to the Pentium Processor table in the section System Board Switches in chapter 2.

The system board of the HP Vectra VE 5/xx series 2 has a Voltage Regulator Module (VRM)

which supplies the Pentium processor with the correct voltage. The VRM allows the processor

to be upgraded without replacing the system board.

The 75 MHz, 90 MHz, 100 MHz, 133 MHz, 150 MHz and 166 MHz processors need a passive

shortening block VRM (providing VCC voltage). The appropriate VRM is provided with each

processor upgrade kit.

Cache Memory

The microprocessor has two 8 KB first-level cache memories: one for instruction codes and

the other for data.

The HP Vectra VE 5/xx series 2 PC has a socket for a 256 KB second-level cache memory

module. There are two modules available, a 256 KB asynchronous cache memory module

(D4049A) or a 256 KB synchronous cache memory module (D3659A).

When the optional second level cache is not installed, the cache socket protector must be

installed in the empty cache. The role of the cache socket protector is to properly terminate

the Pentium host bus.

Main Memory

The HP Vectra VE 5/xx series 2 PC has six DRAM (Dynamic Random Access Memory)

sockets on the system board. The PC uses 60ns, 32-bit wide, EDO memory modules. 8 MB

(two 4 MB modules) or 16 MB (two 8 MB modules) of memory is supplied as standard,

expandable to 128 MB.

Memory modules

must be installed in pairs of identical modules

.

NOTE Install I. Bank C supports only single density

memory modules.

EDO (Extended Data Out) memory is a new type of memory that boosts overall access times.

It does this by utilizing the clock cycles more effectively, improving data throughput.

The memory upgrades available are:

• 8 MB kit (2×4 MB modules), 32-bit, 60 ns (D3646A)

• 16 MB kit (2×8 MB modules), 32-bit, 60 ns (D3647A)

• 32 MB kit (2×16 MB modules), 32-bit, 60 ns (D3648A)

• 20×4 MB module kit, 32-bit, 60 ns (D2878A)

• 20×8 MB module kit, 32-bit, 60 ns (D2879A)

System ROM/BIOS

The Vectra VE 5/xx series 2 has a BIOS system ROM that uses flash EEPROM technology.

The flash ROM can be updated with the latest BIOS firmware using the Phlash program

(PHLASH.EXE) supplied with the firmware upgrade. Refer to "Updating the System ROM," in

chapter 3.

The PC has HP’s new style BIOS co-developed with Phoenix Technologies. The system BIOS

is identified by the version number GU 05.xx.

POST

The Power-On Self Test (POST) is performed when the PC is started. The POST displays a

graphic screen with the HP Vectra logo. If the POST detects an error, the error message is

displayed and the SETUP program can be run to check the configuration.

To see the tests performed during the POST, press [ESC] when the HP Vectra logo appears

and the display will switch to text mode. In this mode, a summary configuration screen will be

displayed at the end of the POST. Pressing the PAUSE/BREAK key at any time will allow you

to inspect the screen contents. Press any key to resume.

SETUP Program

The HP Vectra VE 5/xx series 2 PC has an integrated SETUP program.

SETUP is started by pressing [F2] when the message Setup=F2 appears during the POST.

Integrated Video Controller

All models feature an integrated 64-bit PCI video controller (Cirrus Logic 5436) with 1 MB

DRAM video memory as standard, upgradable to 2 MB (refer to "Installing Video Memory" in

chapter 2).

All models are DDC-1 compliant. This allows the PC to automatically configure for the

optimum video settings (such as maximum refresh rate) when a DDC-1 compliant display is

connected.

NOTE Video modes incorporating an 85 Hz refresh rate are

only available on HP Vectra VE 5/xx Series 2 PCs

with System BIOS versions GU 07.01 (featuring

Video BIOS version 1.10) and later.

Flexible Disk Controller

The integrated flexible disk controller is on the ISA bus and supports two devices. Flexible disk

drives and tape drives can be connected to this controller.

IDE Disk Controller

The integrated IDE hard disk controller is on the PCI bus. This controller has two channels,

each with a separate data cable and system board connector. Each channel supports up to two

devices.

The primary channel is marked HDD on the system board and is recommended for hard disk

drives. Connecting a CD-ROM drive to this channel is not recommended, as the CD-ROM

drive can slow down the transfer rate of a faster IDE device.

On the primary channel data cable, the inside device connector is used for the master

(bootable) drive, and the outside (or end) device connector for the slave drive. This is true as

long as the Cable Select (CS) jumper on the IDE device is set (default factory configuration).

The secondary channel is marked CD-ROM on the system board and has red device

connectors. This channel is for a supplementary hard disk drive or CD-ROM drive. The cable

has one device connector, allowing a single IDE device to be connected.

Mounting Rails

To install non-HP drives (hard disk drives, tape drives, CD-ROM drives) in the front access

slots, the Mounting Rails Kit 5063-7922 must be ordered. This kit contains two sets of rails,

one for a 3.5-inch drive and one for a 5.25-inch drive.

Supported Drives

Flexible disk drives:

• 3.5-inch, 1.44 MB flexible disk drive (D2035B)

• 5.25-inch, 1.2 MB flexible disk drive (D2881B)

Hard disk drives:

• 3.5-inch, 640 MB IDE hard disk drive (D2929A)

• 3.5-inch, 1.2 GB IDE hard disk drive (D2930A)
