About Your BIOS
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, 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.

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.
• 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. Refer to “Power Management in the BIOS” on page 27
.
• Boot: for choosing 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
values may cause system boot failure. Should this occur, press the key while you are in the Setup program to load
the Setup program’s default values. This should enable the computer to boot properly.
HP strongly recommends that you make a note of any changes you make while in the Setup program.

Why Upgrade?
Why Upgrade?
Your computer uses some of the latest hardware technology to achieve outstanding performance. If required,
performance can be even further enhanced thanks to this computer’s upgradeable design.
Main Memory Main memory is the workspace of the computer in which the processor stores all work in progress. You can increase the
size of the computer’s workspace by adding more main memory.
To find out more about upgrading the main memory, refer to “Upgrading Main Memory” on page 39.
Video Memory Video memory stores everything that you see on your computer screen. In order to provide a solid image on the screen,
the screen image has to be continually refreshed. The computer’s graphics system uses the image stored in video memory
to refresh the screen. Increasing the amount of video memory enables higher screen resolutions, higher refresh rates and
many more colors for existing resolutions, enhancing and accelerating graphics-intensive applications.
To find out more about upgrading the video memory, refer to “
Upgrading Video Memory” on page 42.
Expansion Cards An expansion card, or accessory board, is a component that usually adds some specialized function to a computer. For
example, installing a network card can, in conjunction with the necessary software and cables, connect a computer to a
network.
To find out more about installing expansion cards, refer to “Adding Accessories” on page 49.
Storage Devices A storage device is a device that stores software (for example, applications, programs, the operating system, data, and so
on). Hard disk drives, CD-ROM drives, tape drives, Zip drives, and floppy disk drives are all examples of storage devices.
To find out more about installing storage devices, refer to “Installing Storage Devices” on page 54.
Processor The processor is the primary computational chip inside the computer. It can be thought of as the computer’s brain. It may

Performance?
The amount of main memory that your computer has depends on the particular model that you have. To see how much
main memory is installed, right-click the My Computer icon on the desktop. Then click Properties in the drop-down menu.
By adding more memory you can significantly improve the computer’s performance. If your computer does not have
enough memory, it uses hard disk space as virtual memory which allows large applications to execute even though the
physical memory is not sufficient. Virtual memory, however, is approximately 200 times slower than main memory.
The amount of main memory your computer requires depends on the operating system and the applications you use. You
may need more memory if you use memory-hungry applications (for example, image processing and desktop publishing
applications) or if you run several applications at the same time.
Your computer is capable of supporting up to 192 MB of main memory (3 x 64 MB), using three memory module sockets
on the system board.
Main memory is available in modules of 16 MB, 32 MB, and 64 MB non-ECC SDRAMs.
If your computer has sufficient memory, installing extra memory will not improve performance.

The amount of video memory that your computer has depends on the particular model that you have. To find out how
much video memory is installed, select the Display icon from the Control Panel and click the Settings tab, then select the
Advanced Properties button.
You should upgrade the amount of video memory if you want to increase your display resolution or the number of
displayable colors.
For example, with 1 MB, you can have up to 65K colors with a screen resolution of 800 x 600 (default setting). If you
increase the resolution to 1024 x 768, you will only be able to have 256 colors available, which will result in a flickering
and bad ergonomic display. In this case, 2 MB of video memory is necessary to keep the optimal colors and refresh rate.
If your computer has 2 MB of video memory on the system board, it cannot be increased (unless you use a separate video
card, such as an AGP video card).
If your computer has an AGP video card supplied with 4 MB of video memory, you can upgrade it to 8 MB by installing a
video memory module.
Note
If you install an AGP video card, the video memory on the system board (if any) will no longer be available. The 2 MB

An expansion card, or accessory board, is a component that usually adds some specialized function to a computer. For
example, installing a network card can, in conjunction with the necessary software and cables, connect a computer to a
network.
There are two types of expansion cards that you can install in your computer: PCI cards and ISA cards. PCI cards use the
computer’s PCI bus (information pathway), and ISA cards use the computer’s ISA bus. The PCI bus is faster than the ISA
bus.
You can tell how many cards are installed by looking at the back of your computer and counting the number of slots that
are occupied. This is the number of expansion cards that are installed.
Your computer supports up to six cards (refer to page 12).
The Windows operating system can automatically recognize and configure many expansion cards that you may want to
install in your computer. With other cards, you will be required either to install a driver, or to run the Windows Add New
Hardware wizard to help Windows to recognize the card.
You must physically install the card before you run the wizard. Refer to your Windows documentation and online help for
more information about using the wizard.
For non plug and play (legacy) expansion cards, the settings selected by Windows may be different from those
recommended by the card’s manufacturer. In this case, the card’s jumper settings and driver options might need to be
altered. Refer to the manual supplied with the card for more information.

Storage Devices?
How Many Storage
Devices Can I Add?
Your computer is supplied with one hard disk drive mounted on an internal shelf, and one front-access 3.5-inch floppy disk
drive. There may also be a CD-ROM drive installed.
Adding additional storage devices is often necessary when, for example, a large amount of information needs to be
frequently accessed.
You can install additional storage devices if, for example, you need extra storage space for your application software.
The number of storage devices that you can add to your computer is determined by the number of mounting shelves that
are unused and by the number of storage device interface channels that are unused.
Your computer has a 3.5-inch floppy disk drive and either a 3.5-inch or 5.25-inch hard disk drive already installed. There
may also be a CD-ROM drive installed.
The on-system board electronics have a total of six interface channels that can support up to six storage devices—two
FDD devices and four IDE devices.
Note
Disk drives ordered from HP may be supplied with mounting rails. Remove all mounting rails from the drive, as your
computer does not need them. You can install a non-IDE device such as a SCSI drive but you will also need to install
an interface card and software for it.

Cables
System Board
Connectors
Your computer has the following cables which may be used by storage devices:
• A primary IDE hard disk drive cable with two connectors. This cable supports up to two IDE hard disk drives, one of
which is already connected to the Master connector on this cable.
• A secondary IDE drive cable with two connectors. If you already have a CD-ROM drive installed, it is connected to the
Master connector on this cable. If you install a CD-ROM drive, or a third hard disk drive, or both, connect it or them to
this cable.
• A floppy disk drive cable. This supports up to two floppy disk drives (or one floppy disk drive and one tape drive). One
3.5-inch floppy disk (Drive A) is already connected to the Master connector on this cable.
If you add a floppy disk drive, hard disk drive, CD-ROM drive, Zip drive, or tape drive, you need to connect it to power
and data cables. The connectors are shaped to fit one way only. The data cables are shown below.

If you install a device that requires a different connector, the connector converter should be supplied with the device.
If you install a hard disk drive and connect it to the cable that the CD-ROM drive is connected to, the hard disk drive
must be connected to the Master connector in the cable from the system board, not the Slave connector. If you have
a CD-ROM drive currently connected to the Master connector, you must reconnect the CD-ROM drive to the Slave
connector of the cable, and then attach the new hard disk drive to the Master connector.
Power Connector for 3.5inch Floppy Disk Drive
Installing an Additional Hard Disk Drive
Refer to the drive’s manual(s) to see if you must set jumpers or if there is a special installation procedure to follow.
