Using ExpressCards
ExpressCards provide additional memory, wired and wireless
communications, multimedia and security features. For example, you can add
an ExpressCard to make wireless wide area network (WWAN) connectivity
available on your computer.
ExpressCards support two form factors:
• ExpressCard/34 (34 mm wide)
• ExpressCard/54 (54 mm wide in an L-shape with a 34 mm connector)
The 34 mm card fits into both the 34 mm and 54 mm card slots. The 54 mm
card only fits into a 54 mm card slot.
See "Specifications" on page 179 for information on supported ExpressCards.
NOTE:
An ExpressCard is not a bootable device.
ExpressCard Blanks
Your computer shipped with a plastic blank installed in the ExpressCard slot.
Blanks protect unused slots from dust and other particles. Save the blank for
use when no ExpressCard is installed in the slot; blanks from other computers
may not fit your computer.
