PC Cards The Notebook PC has two PC Card sockets designed to interface with two Type I/II or one Type III card. It allows you to expand and customize your computer to meet a wide range of application needs. The PC Card standard accommodates a number of function, communication, and data storage expansion options such as Memory/Flash Cards, FAX/Modems, Networking Adapters, and MPEG I/II decoder cards. The Notebook PC supports PCMCIA 2.1, 32bit CardBus, and Zoomed Video (ZV).

By comparison, the standard 16-bit PC Card bus can handle only 20MB/sec. Since the Notebook PC is equipped with CardBus' broader, faster data pathway, it can handle bandwidth-hungry operations, such as 100Mbps Fast Ethernet, Fast SCSI peripherals, and ISDN-based video conference that are cuttingedge even for desktop systems.

The CardBus socket is backward-compatible with 16-bit PC Cards serving at 5 volts operation while CardBus operates at 3.3 volts to reduce power consumption. As part of the Notebook PC's advanced architecture, the Zoomed Video specification provides for full frame-rate video display channel for applications like MPEG decoders for movies and games, TV tuners, live video input, video capturing, and video conferencing. The Zoomed Video (ZV) port (lower socket) allows video data on a PC Card to be transferred directly into the VGA frame buffer, bypassing the CPU and PCI system bus. It can promise a high quality real-time full-motion video playback without holding back the CPU and system bus performance. 4. Using 44

32-bit CardBus & Zoomed Video Port (lower socket)
CardBus support (lower socket) allows PC Cards and their hosts to use 32-bit bus mastering and operate
at speeds of up to 33MHz, transferring data in burst modes comparable with PCI’s 132MB/sec. By
comparison, the standard 16-bit PC Card bus can handle only 20MB/sec. Since the Notebook PC is
equipped with CardBus’ broader, faster data pathway, it can handle bandwidth-hungry operations, such
as 100Mbps Fast Ethernet, Fast SCSI peripherals, and ISDN-based video conference that are cutting-
edge even for desktop systems. The CardBus peripherals support plug and play.
The CardBus socket is backward-compatible with 16-bit PC Cards serving at 5 volts operation while
CardBus operates at 3.3 volts to reduce power consumption.
As part of the Notebook PC’s advanced architecture, the Zoomed Video specification provides for full
frame-rate video display channel for applications like MPEG decoders for movies and games, TV tun-
ers, live video input, video capturing, and video conferencing. The Zoomed Video (ZV) port (lower
socket) allows video data on a PC Card to be transferred directly into the VGA frame buffer, bypassing
the CPU and PCI system bus. It can promise a high quality real-time full-motion video playback without
holding back the CPU and system bus performance.
