ExpressCards
An ExpressCard is a next-generation, high-performance PC Card, which must be inserted into the
ExpressCard slot.
Like standard PC Cards, ExpressCards are designed to conform to the standard specifications of the
Personal Computer Memory Card International Association (PCMCIA).
NOTE An ExpressCard can also add TV tuner functionality to the computer. For more
information, refer to the manufacturer's user guide.
Selecting an ExpressCard
ExpressCards use one of 2 interfaces and are available in 2 sizes. The ExpressCard slot on the
computer supports both interfaces and both sizes. For example, you can use
● An ExpressCard with either a USB interface or a PCI Express interface.
● A full-size ExpressCard, called ExpressCard/54 (1), or a smaller ExpressCard, called
ExpressCard/34 (2).
The ExpressCard procedures described in the following sections are the same for both interfaces
and both sizes.
Configuring an ExpressCard
CAUTION To prevent loss of support for other ExpressCards, install only the software
required for the device. If you are instructed by the ExpressCard manufacturer to install device
drivers:
Install only the device drivers for your operating system.
Do not install other software, such as card services, socket services, or enablers, supplied by
the ExpressCard manufacturer.
