Installing an Expansion Card
Expansion cards, such as a scanner card or a modem, increase the capabilities of
your computer. There are many different types of expansion cards available on the
market. Before purchasing an expansion card or equipment that requires the
installation of an expansion card, ensure that the new card and equipment is
compatible with your Internet PC.
Determining Expansion Card Compatibility
The types of cards compatible with your Compaq 7800 Series Internet PC include
the following:
x Plug and Play Peripheral Component Interconnect (PCI) cards
x Industry Standard Architecture (ISA) cards
(available on select models only)
x Accelerated Graphics Port (AGP) cards
(available on select models only)

Plug and Play PCI cards are automatically recognized and resourced upon
installation by the Microsoft Windows operating system and Basic Input Output
System (BIOS).
The operating system and the BIOS do not automatically recognize ISA cards. The
card jumper settings may require manual adjustment based on your currently
available system resources, such as the IRQ (

resource settings according to the card manufacturer’s instructions.
