Using PC Cards
Your computer has a PC card slot.
PC cards are credit card-sized peripheral products based on the standards
developed by PCMCIA (Personal Computer Memory Card International
Association). PCMCIA is a non-profit association for promoting the
interchangeability among mobile computers where ruggedness, low
power, and small size are critical. Ever since its foundation, the
association has been continuing their efforts to add new specifications to
the PC card standard as new needs arise in the market.
PC Card Type
Your computer’ s PC card slot can accommodate two type II cards or a
type III card. Type II cards are typically used for I/O devices such as
data/fax modems, LANs, and mass storage devices. Type III cards are
used for devices whose components are thicker, such as rotating mass
storage devices. Extended cards allow the addition of components that
must remain outside the system for proper operation, such as antennas for
wireless applications.
CardBus Support
Your computer’ s PC card slot supports CardBus specifications. CardBus
is the 32-bit version of PC card technology. It allows speeds of up to
133 Mbps at 33 MHz. Typical applications are SCSI host bus and
high-speed network cards.
Inserting and Removing a PC Card
NOTE:
l Some PC cards require additional system resources. Before using such PC card,
you may have to free other system resources for the PC card.
l Although some PC cards can be inserted and removed without turning off the
computer, you cannot remove or install PC cards in the Standby mode.
