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 - information about the set of programs that controls 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
won’t need to reference every day, but which you will find useful if you ever want to upgrade or customize your
computer.

Main Components and Features of the System Board
The main components and features of your HP Brio PC are:
•Fast IDE controller with two channels on the PCI bus:
❒A primary IDE channel. For example, used for one or two IDE hard disk drives.
❒A secondary IDE channel. For example, used for IDE CD-ROM drives, IDE hard disk drives, or IDE zip drives.
•Floppy Disk Drive controller supporting two devices.
•Rear panel connectors:
❒One mouse socket
❒One keyboard socket
❒One display connector
❒One Universal Serial Bus (USB) connector
❒One parallel port
❒One serial port
•Keyboard/mouse controller and interface.
•Two main memory sockets (168-pin SDRAM DIMM), allowing installation of up to 128 MB of main memory
(2 x 64 MB). The slots can be filled in any order.
•1 or 2 MB of video memory on the system board. If the computer has 1 MB of video memory, it can be upgraded to 2 MB.
•512 KB of level two cache memory (SRAM) soldered on the system board.

Expansion Card Slots
There are five expansion card slots on the backplane for the installation of:
• Two 32-bit PCI cards and three 16-bit ISA cards,
or
• Three 32-bit PCI cards and two 16-bit ISA cards.
System Board Configuration Jumpers
Microprocessor
Configuration
Jumper (JP5)
This jumper allows the system board to be set so that it matches the speed of the installed processor. You only need to
change the microprocessor configuration jumper if you install a new processor that has a different processor speed to the
one that is currently installed.
Refer to “Upgrading a Processor” on page 45 for more information about installing a processor upgrade, and changing the
jumper settings.
CPU Voltage
Jumper (JP4)
Use this jumper to change the output of the on-board switching voltage regulator for different processors. Refer to
“Upgrading a Processor” on page 45 for more information about installing a processor upgrade, and changing the jumper
settings.
CMOS Jumper 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 changes to the CMOS configuration. This is the default setting. Refer to
“Clearing the CMOS Configuration” on page 31 for information about clearing the CMOS and using this jumper.
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
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. This figure shows where the connectors are located on
the sound card.
Note The internal connectors Internal Speaker Connector, Multimedia Control Panel Connector, Telephone Answering
Device Connector and Multimedia Control Panel Microphone Connector are not used on this computer.

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 let you hear output only from music CDs. Through the rear panel jack on
your computer you can 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 used for are given below.
LINE IN Connect devices such as a cassette, DAT, or Minidisc player for playback and recording.
MIC 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, or 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.
SPK 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 available 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 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 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 SPK jack is for a highly amplified output and is therefore not suitable for connecting headphones.

Your Sound Card
Connecting Audio Devices to the Internal Connectors
There are also several internal connectors located on the sound card itself. These are shown on page 13 , and those that
are used are described below.
AUX In Connector This Auxiliary Connector allows you to connect an additional internal audio source such as a TV tuner, or another 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 Connector The 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:
Pin Signal I/O
1 Analog Ground -
2 AUX right channel IN

Power Consumption
Power Consumption
1. The power supply in your HP Brio PC continues to supply power to the CMOS memory, even when turned off.
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
Note When the computer is turned off with the power button on the front panel, the power consumption falls below 3 W,
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.
ISA Expansion Card Slots PCI Expansion Card Slots
+ 5 V 4.5 A limit per slot (limited by system board) + 5 V 4.5 A maximum per slot
