ExpressCard Slot
One 26pin Express card slot is available to support one
ExpressCard/34mm or one ExpressCard/54mm expansion
card. This new interface is faster by using a serial bus
supporting USB 2.0 and PCI Express instead of the slower
parallel bus used in the PC card slot. (Not compatible with
previous PCMCIA cards.)
