Upgrading Your HP PC

Upgrading Your HP PC

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 upgradable design.

Main Memory Main memory is the workspace of the computer. It is in this workspace that 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 the Main Memory” on page 12.

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 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 the Video Memory” on page 13.

Cache Memory Cache memory is used by processors to accelerate access times for frequently used data and instructions. For example,

cache memory keeps a copy of the last data read or written by the processor. If the same data is requested again by the
processor, it is supplied from the cache, and not main memory, at a reduced access time.

To find out more about upgrading the cache memory, refer to “

Upgrading the Cache Memory” on page 14.

Upgrading Your HP PC

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 “

Installing Expansion Cards” on page 15.

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, zip drives, tape 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 16.

Processor The processor is the primary computational chip inside the computer. It can be thought of as the computer’s brain. It may

be upgraded to provide more power for processor-intensive applications.

To find out more about installing a processor upgrade, refer to “Upgrading the Processor” on page 17.

Upgrading the Main Memory

Upgrading the Main Memory

How Much Main
Memory Does My
Computer Have?

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, restart your computer and press the key when

F2=Setup is displayed. This displays a

summary screen showing the computer’s configuration. The amount of main memory installed is shown on this screen (in
the System RAM field). Alternatively, you can run PC Doctor for Windows (from within Windows 95) and check the System
Info.

Why Add More
Main Memory?

Adding more memory can improve the performance of your computer. The reason for this is that if your computer does
not have enough memory, it will need to use hard disk space as virtual memory. Using this technique, the operating system
makes the memory seem larger than it physically is, allowing large applications to execute even though the physical
memory is not sufficient. Virtual memory is approximately 200 times slower than main memory. In this case, adding
memory will significantly improve the computer’s performance.

The amount of main memory your computer requires depends on the operating system and the applications you use. You
will 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.

How Much Main
Memory Can I Add?

Your computer is capable of supporting up to 192 MB of main memory, using six memory module sockets on the system
board.

Will Adding Memory
Always Improve
Performance

Adding memory will not always improve performance. If your computer has sufficient memory, installing extra memory
will not improve performance.

For instructions on how to add main memory modules, refer to “

Installing Main Memory” on page 25.

Upgrading the Video Memory

Upgrading the Video Memory

How Much Video
Memory Does My
Computer Have?

The amount of video memory that your computer has depends on the particular model that you have. You may have 1 MB
of video memory installed on the system board, or 4 MB installed on a video card. To see how much video memory is
installed, restart your computer and press the key when

F2=Setup is displayed. This displays a summary screen

showing the computer’s configuration. The amount of video memory available is shown on this screen (in the Video RAM
field). Alternatively, you can run PC Doctor for Windows (from within Windows 95) and check the System Info.

How Does Video
Memory Work?

The image on the screen is made up of tiny dots called pixels. Each pixel has a color, and every color is represented by a
value. Video memory stores the color value of every pixel.

The screen resolution determines how many pixels make up a displayed screen. The number of pixels required is
typically very large (for example, 300,000 pixels for a standard VGA screen with a resolution of 640 X 480).

Why Increase the
Amount of Video
Memory?

Increasing your display resolution will increase the total number of pixels needed to define an entire screen. Similarly,
increasing the number of displayable colors will increase the amount of data required to display the pixels. Increasing
either of these parameters will increase your requirement for video memory.

More video memory gives support for higher screen resolutions, for higher refresh rates (the frequency at which the
screen’s horizontal lines are recharged), and for many more colors for existing resolutions.

How Much Video
Memory Can I Add?

If your computer has 1 MB of video memory on the system board, you can increase it to 2 MB. If your computer has 4 MB
of video memory on a video card, you can also increase it. Contact your HP-authorized support agent or reseller for more
information.

For instructions on how to upgrade the video memory, refer to “

Installing Video Memory” on page 28.

1 Why Upgrade?

Upgrading the Cache Memory

Upgrading the Cache Memory

How Much Cache
Memory Does My
Computer Have?

Your computer has level-one and level-two cache. The cache level refers to the proximity of the cache to the processor.
Level-one cache is integrated in the processor and operates at the same speed as the processor, for example, 200MHz.
Level-two cache is not integrated in the processor but is located on the processor’s local bus (see “

Upgrading the

Processor” on page 17) and so operates at the same speed as the local bus, for example, 66 MHz.

The design of level-two cache makes it faster than conventional main memory (see “

Upgrading the Main Memory” on

page 12), which is also located on the local bus.

In general, level-one cache incorporates 8 or 16 KB of data cache and 8 or 16 KB of instruction cache.

The amount of level-two cache that your computer has depends on the particular model that you have. To see how much
level-two cache memory is installed, restart your computer and press the key when

F2=Setup is displayed. This

displays a summary screen showing the computer’s configuration. The amount of level-two cache memory is shown on
this screen (in the System Cache field).

Why Add More
Cache Memory?

Increasing the amount of cache memory in your computer will improve the performance of your computer.

How Much Cache
Memory Can I Add?

Your computer is capable of supporting up to 512 KB of level-two cache memory, using one cache memory module socket
on the system board. If your computer currently has no level-two cache memory installed, or has 256 KB of level-two cache
memory installed, you can upgrade your computer by installing a new cache memory module. If your computer has no
level-two cache, you can install either a 256-KB module or a 512-KB module.

For instructions on how to install a cache memory module, refer to “

Installing Cache Memory” on page 33.

Installing Expansion Cards

Installing Expansion Cards

How Many
Expansion Cards
Does My Computer
Have?

The number of expansion cards that your computer has depends on the particular model that you have. 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.

There are two types of expansion cards that you can install in your computer: Industry-Standard Architecture (ISA)
cards and Peripheral Component Interconnect (PCI) 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.

Why Add More
Expansion Cards?

Adding more expansion cards will increase the capability of your computer.

How Many
Expansion Cards Can
I Install?

Your computer supports up to six cards.

For instructions on how to add an expansion card, refer to “

Installing Expansion Cards” on page 35.

Installing Storage Devices

Installing Storage Devices

How Many Storage
Devices Does My
Computer Have?

Your computer is supplied with one hard disk drive on an internal shelf (either 3.5-inch or 5.25-inch), one 3.5-inch floppy
disk drive, and one CD-ROM drive. Some models are also supplied with a tape drive.

Why Add More
Storage Devices?

Adding additional storage devices is often necessary when, for example, a large amount of information needs to be
frequently accessed.

How Many Storage
Devices Can I Add?

The number of storage devices that you can add to your computer is determined by the number of shelves available.

For instructions on how to add a storage device, refer to “

Installing Storage Devices” on page 43.

Note

The on-system board electronics support up to six devices (two FDD (Flexible Disk Drive) devices and four IDE
(Integrated Drive Electronics) devices). You can install a non-IDE device such as a SCSI drive but you will need to
install an interface card and software for it.

In addition to the 3.5-inch floppy disk drive and the CD-ROM drive, your computer has two front-access device
shelves available for new drives. Note that with some models one of these shelves will be already occupied by a tape
drive.

Upgrading the Processor

Upgrading the Processor

What Does the
Processor Do?

The processor is the primary computational chip inside the computer. It can be thought of as the computer’s brain. The
processor communicates with other parts of the computer via three buses (information pathways):

• the processor’s local bus

• the PCI (Peripheral Component Interconnect) bus

• the ISA (Industry-Standard Architecture) bus

Each bus connects functional components of the computer which have similar data-handling requirements. The three
buses operate at different speeds and are connected via bridges. (A bridge converts data from one bus into a format that
is suitable for the destination bus.)

Why Upgrade the
Processor?

The speed at which the processor can perform tasks is determined by the processor’s internal speed; the faster the internal
speed, the faster tasks can be performed. Replacing the processor by one with a faster internal speed will improve the
performance of your computer.

What Is the Fastest
Processor I Can
Install?

New, faster processors are being developed all the time. Check with your HP-authorized support agent or reseller to find
out what the fastest processor is that you can install in your computer.

For instructions on how to install a processor upgrade, refer to “

Installing a Processor Upgrade” on page 55.

Upgrading the BIOS

Upgrading the BIOS

What Is the BIOS? The BIOS (Basic Input/Output System) is the set of programs that automates the computer’s components. The BIOS is

stored in a chip on the system board.

The operating system and programs running on your computer use the BIOS to simplify their instructions and reduce
their size, giving a more efficient system.

Why Upgrade the
BIOS?

Hewlett-Packard is continually improving the BIOS in its computers, introducing new features and making them more
efficient. You can benefit from such progress and keep your own computer up-to-date by upgrading the BIOS.

How Do I Upgrade
the BIOS?

Installing Storage Devices

Installing Storage Devices

You can install additional storage devices if, for example, you need extra storage space for your application software.

Your computer has two internal shelves for 3.5-inch hard disk drives, and one internal shelf for a 5.25-inch hard disk
drive. Depending on your model, one of these internal shelves will already have a drive installed in it. You can install
another two hard disk drives in the two remaining internal shelves.

Your computer also has a 3.5-inch floppy disk drive and a CD-ROM drive installed in front-access device shelves. Two
more front-access device shelves are available to install other drives. Note that some models also have a tape drive
installed, leaving one front-access shelf available for a new drive.

Your computer has the following cables which may be used by storage devices:

• An Enhanced IDE (Integrated Drive Electronics) hard disk drive cable. This cable supports up to two IDE hard disk

drives. One hard disk drive is already connected to the master (boot) connector on this cable. This cable is labeled Hard
Disk.

• A second Enhanced IDE drive cable with two connectors. The CD-ROM drive is connected to one connector on this

cable. If you install a zip drive, for example, connect it to the second connector on this cable. This cable is labeled
CD-ROM.

• 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 is already connected to this cable. This cable is labeled Flexible Disk.

Note

Disk drives ordered from HP are supplied with mounting rails. If you order your drive from another supplier, you
should use the drive mounting rails supplied with your computer.

Note

Although there are three connectors on the floppy disk drive cable, your computer only supports two drives on the
cable.
