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.

2 About Your BIOS
The BIOS in Your Computer
The BIOS in Your Computer
What Is the BIOS? The BIOS has two main roles:
• It tests and configures the computer’s hardware components during the POST at power on, and lets you perform
further configuration by using the Setup program.
• It provides the link between the software running on your computer, which has been written to be independent of any
particular computer, and your computer’s hardware (the hard disk, the keyboard, the display, and so on).
The BIOS is part of the System ROM and is stored in a chip on the system board. A computer’s BIOS is specific to that
computer.
What Can I Do with
the BIOS?
You can configure certain aspects of your computer by using the Setup program which is part of the BIOS. Refer to “The
HP Setup Program” on page 23 for more information about the Setup program.
23
2 About Your BIOS
The HP Setup Program
The HP Setup Program
The built-in Setup program is accessed by pressing the key during the POST. Online help for an item on the Setup
screen can be obtained by highlighting the item (refer to page 24
for instructions on how to use the key functions). Help
is then displayed on the right of the screen. It is updated as you move the cursor to each field.
If you have any doubts about using the Setup program, contact your reseller for help.
The band along the top of the screen offers the following menus:
• Main: for basic system configuration.
• Advanced: for setting the Advanced Features available in the BIOS.
• Security: for setting a password to restrict access to your computer. For information on how to set a password, refer
to “
Restricting Access to Your Computer - Setting a Password” on page 26.
• Power: for selecting power-management modes to reduce the amount of energy used after specified periods of
inactivity.
• Boot: for selecting your boot device order and priority. Refer to “Boot Device Priority” on page 25.
• Exit: for leaving the Setup program. Refer to “Saving Your Changes and Leaving Setup” on page 25.
The Setup program changes system behavior by modifying the power-on initialization parameters. Setting incorrect

Boot Device Priority
You can select the order of the devices from which the BIOS attempts to boot the operating system. During the POST, if
the BIOS is unsuccessful at booting from one device, it will try the next one on the Boot Device Priority list until an
operating system is found. The default boot device is the floppy disk. To speed up booting, you may wish to set the hard
disk as the default boot device. If you ever need to boot from a floppy though, remember to reset the floppy as the
default boot device.
The Boot Device Priority can be changed through the Boot menu. Use the or arrows to move along the top
of the main menu bar to its location. The item is then highlighted and displays the available boot options.
To select the boot device, use the and arrows, then press the key to move the device up the list, or the
key to move it down the list.

You can also change the boot order just for the current boot. To do this, press while the logo and the message
Press <F2> to enter SETUP are displayed during system startup. This initially displays the POST before displaying

2 Select the Security menu group, then select the “Set Password” item.
3 You are asked to enter the password twice. Be sure to save your changes before you exit the Setup program.
Password on Boot Enabling a password entry on boot can provide a power-on password prompt to prevent your computer being started or
used in your absence. The password is entered when the POST has completed, before the computer finishes its normal
startup procedure. Password on Boot can only be enabled if a password has already been set. It should be noted that
this password option is not linked with your Windows operating system.
To enable a Password on Boot:
1 Start the Setup Program.
2 Select the Security menu group, then enable the “Password on Boot” item.
3 Be sure to save your changes before you exit the Setup program.

After three unsuccessful attempts, your computer will be disabled. If this is the case, turn your computer off and
then on again, then enter the correct password. If you have forgotten your password, you need to clear the CMOS
configuration. Refer to page 31
for an explanation on how to clear the CMOS.
