About This Guide
About This Guide
This Online Reference Guide is broken down into three main sections:
•About Your Hardware - information about the main hardware components that make up your computer: the system
board, your sound card, your keyboard, and so on.
•About Your BIOS (Basic Input/Output system) - information about the set of programs that control the input and output
of data to peripherals.
•Upgrading and Adding Accessories - information about how to install new hardware components such as main memory
or expansion cards.
Purpose of This Guide
The purpose of this guide is to provide you with technical information about your computer. This is information that you
will not need to reference every day, but which you will find useful if you ever want to upgrade or customize your
computer. You may find it useful to print a copy of this book.

1 About Your Hardware
Main Components and Features of the System Board
Main Components and Features of the System Board
The main components and features of your HP Brio PC are:
•Enhanced IDE controller with two channels on the computer bus:
❒A primary IDE channel used, for example, for one or two IDE hard disk drives.
❒A secondary IDE channel used, for example, for IDE CD-ROM drives, IDE hard disk drives, or IDE Zip drives.
•Floppy Disk Drive controller supporting two devices.
•Rear panel connectors:
❒1 mouse socket
❒1 keyboard socket
❒1 display connector
❒2 Universal Serial Bus (USB) connectors
❒1 parallel port
❒1 serial port
•The main memory controller supports two or three DIMM slots. Each slot can host a 168-pin unbuffered DIMM module,
for a total of up to 192MB of dynamic random access memory. These slots can be filled in any order.
•Depending on the model you have purchased, your computer is supplied with one of the following:
❒An on-board video controller with 2MB of video memory on the system board.
❒An AGP video card installed in the AGP expansion slot.

Main Components and Features of the System Board
•Six expansion card slots for the installation of:
❒Two 32-bit PCI cards, three 16-bit ISA cards and one AGP card,
or
❒Three 32-bit PCI cards, two 16-bit ISA cards and one AGP card.
System Board Configuration Jumpers
Clear CMOS
Jumper (J22)
The CMOS memory stores information, such as your computer’s configuration, which is preserved when you turn off your
computer. A jumper placed on pins 1-2 prevents change to the CMOS configuration. This is the default setting. Refer to
“Clearing the CMOS Configuration” on page 33 for information about clearing the CMOS and using this jumper.
Microprocessor
Configuration Jumper
(J23)
This jumper allows the system board to match the speed of the installed processor. You only need to change the
microprocessor configuration jumper if you install a new processor with a different speed to the one that is currently
installed. Refer to “Upgrading a Processor” on page 46 for information about installing a processor upgrade and changing
the jumper settings.
Note PCI expansion card slots are generally white plastic grooves.
ISA expansion card slots are generally black plastic grooves lined with silver.

Your Sound Card
Your Sound Card
Depending on the computer you have purchased, a sound card may be already installed. The sound card has several
connectors that allow you to connect the card to other devices. The figure below shows where the connectors are located
on the sound card.

Multimedia Control Panel Connector.
Without these jumpers, the sound card
will not output sound through the rear
panel. (These jumper connections are set
by default).

1 About Your Hardware
Your Sound Card
Connecting Audio Devices to the Rear Panel
You can connect external speakers, a microphone, or other audio devices to the rear panel. Do not connect headphones
to the jack on the CD-ROM drive, as this will only let you hear output from music CDs. Through the rear panel jack on
your computer you will hear sounds from training presentations, MIDI music files, any other audio software, and music
CDs too.
Details of what each jack on the sound card is for are given below.
LINE IN Connect devices such as a cassette, DAT, or Minidisc player for playback and recording.
MICROPHONE Connect a microphone for voice input.
LINE OUT Bypass the sound card’s internal amplifier to connect powered speakers, an external amplifier for audio
output, a recording device (tape deck), or stereo headphones.
You can use this jack for headphones with limited power output. You can also use it with amplified
speakers which have a dedicated headphone jack for this purpose.
SPEAKERS Connect speakers for audio output from the card’s built-in power amplifier. Adjust the volume from within
the software or from the multimedia control panel if this feature is on your computer.
MIDI/GAME Connect a joystick (for game software) or MIDI instrument. The MIDI port is disabled by default. You will
have to enable this port if you wish to use it with a MIDI.
Warning Before connecting any headphones or speakers, always turn the volume down to avoid discomfort from unexpected
noise or static. Listening to loud sounds for prolonged periods of time may permanently damage your hearing. Before
putting on any headphones, place them around your neck and turn the volume down. Then, put on the headphones
and slowly increase the volume by using the Audio Mixer Applet or the enhanced keyboard until you find a
comfortable listening level, where the sound is clear without being too loud. When you can hear comfortably and
clearly, without distortion, leave the volume control in that position.
Warning The SPEAKERS jack is for a highly amplified output and is therefore not suitable for connecting headphones.

Connecting Audio Devices to the Internal Connectors
There are also several internal connectors located on the sound card itself. These are shown on page 14 , and those that
are used are described below.
AUX In ConnectorThis Auxiliary In Connector allows you to connect an additional internal audio source such as a TV tuner, or other similar
card. It can also be used to accept decompressed audio data from an MPEG video card. The AUX In connector has the
following pin assignments:
CD Audio ConnectorThe CD Audio Connector, labeled “CDAUDIO”, allows you to connect the sound card to the CD-ROM drive via the audio
cable, so that you can listen to audio from the CD-ROM drive. The CD Audio Connector has the following pin
assignments:

Power Consumption
Power Consumption
Typical Power Consumption/Availability
There is a maximum per-slot limit of 25 W between all supply rails.
Note The figures given below are valid for computers with a standard configuration—no expansion cards and no CD-ROM
drive. For certain configurations, the power consumption values will be higher.
Full Power Mode <44 W
Suspend Mode <30 W
Off <3 W1
1. The power supply in your HP PC continues to supply power to the CMOS memory, even when turned off.
Note When the computer is turned off with the power button on the front panel, the power consumption falls below three
watts, but it is not zero. The special on/off method used by this computer considerably extends the lifetime of the
power supply. To reach zero power consumption in “off” mode, either unplug the computer from the power outlet or
use a power block with a switch.
