Main MemoryMain 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 MemoryVideo 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 the Video Memory” on page 13

Will Adding Memory
Always Improve
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 when Press <F2> to enter SETUP is displayed at
the bottom of the screen. This displays a series of screens that show the computer’s configuration. The amount of main
memory installed is shown on the Main screen in the Memory fields.
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
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.
Your computer is capable of supporting up to 128 MB of main memory, using four memory module sockets on the system
board.
Adding memory will not always improve performance. If your computer has sufficient memory, installing extra memory
will not improve performance.

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
The amount of video memory that your computer has depends on the particular model that you have. You may have 1 MB
or 2 MB of video memory installed on the system board. To find out how much video memory is installed, from Windows
95 select the Display icon from the Control Panel and click the Settings tab, then select the Advanced Properties button.
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 makes it possible to obtain higher screen resolutions, higher refresh rates (the frequency at which
the screen’s horizontal lines are recharged), and many more colors for existing resolutions.
If your computer has 1 MB of video memory on the system board, you can increase it to 2 MB. To find out how much video
memory is installed, from Windows 95 select the Display icon from the Control Panel and click the Settings tab, then select

Expansion Cards?
Expansion cards have sockets at one end which, once the card is installed, are accessible from the back of the computer.
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.
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.
These three upper expansion
card slots are not available.

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.
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.
In addition to the 3.5-inch floppy disk drive and a hard disk drive, your computer has four front-access device shelves
available for new drives (note that one of these shelves may already be occupied by a CD-ROM drive). There is also one
internal shelf available, which may be used for an additional hard disk drive.
The on-system board electronics have a total of six interface channels that can support up to six storage devices—two
FDD (Floppy Disk Drive) devices and four IDE (Integrated Drive Electronics) devices.
Note
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.

What Is the Fastest
Processor I Can
Install?
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.)
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.
New, faster processors are being developed all the time. Check with your HP-authorized support agent or reseller to find
out what is the fastest processor that you can install in your computer.
