PC Card slot
There is one Type II CardBus PC Card slot found on the right side of the
computer. The slot accepts credit-card-sized cards that enhance the
usability and expandability of the computer. These cards should have a
PC Card logo on them.
PC Cards (formerly PCMCIA) are add-on cards for portable computers,
giving you expansion possibilities long afforded by desktop PCs.
CardBus improves on the 16-bit PC card technology by expanding the
bandwidth to 32 bits.
Note: Refer to your card manual for details on how to install and
use the card and its functions.
Inserting a PC Card
Insert the card into the slot and make the proper connections (e.g.,
network cable), if necessary. See your card manual for details.
