[. . . ] Notebook PC Hardware User's Manual Product Name: Notebook PC Hardware Manual Revision: 1. 00 E891 Release Date: Dec 2001 Safety Statements Federal Communications Commission Statement This device complies with FCC Rules Part 15. Operation is subject to the following two conditions: · This device may not cause harmful interference, and · This device must accept any interference received, including interference that may cause undesired operation. This equipment has been tested and found to comply with the limits for a class B digital device, pursuant to Part 15 of the Federal Communications Commission (FCC) rules. These limits are designed to provide reasonable protection against harmful interference in a residential installation. [. . . ] The DVD specification supports discs with capacities from 4. 7GB to 17GB and access rates up to 22. 16MBytes/s. The Notebook PC's DVD-ROM drive is only single-sided; double-sided DVD (8. 5GB and higher) requires manually reversing the disc in order to access the reverse side. DVD is essentially a bigger, faster CD that can hold video as well as audio and computer data. With these capacities and access rates, DVD discs can provide you with dramatically-enhanced high-color, full-motion videos, better graphics, sharper pictures, and Dolby® Digital Surround for a theater-like experience. DVD aims to encompass home entertainment, computers, and business information with a single digital format, eventually replacing audio CD, videotape, laserdisc, CD-ROM, and perhaps even video game cartridges. DVD has widespread support from all major electronics companies, all major computer hardware companies, and most major movie and music studios. 43 Using the Notebook PC Software To meet customer requirements for a complete DVD solution, a software playback solution is provided. The provided software has been optimized for playback of MPEG2 (Motion Picture Experts Group specifications for data compression) encoded video clips as well as encrypted DVD movie titles. Decoding digital MPEG2 video is accomplished through software only, eliminating the need for expensive hardware. Although the software will function on Intel 233-333MHz based notebooks, playback quality is reduced since loss of video frames (video images look as though they are skipping sections of the movie) during playback may occur. Software playback performance on Intel's 400MHz processor platforms or faster is required to sustain 30 fps (frames per second) which approaches the quality of most hardware playback solutions. NOTE: Since MPEG2 video decoding is done through software, a processor of at least 400MHz Pentium II is recommended to provide real-time playback without frame skips. An MPEG2 hardware decoder PCMCIA card is required on Notebook PCs with slower processors for smooth DVD playback. Using a CD A CD drive letter should be present regardless of the presence of a CD disc in the drive. After the CD is properly inserted, data can be accessed just like with hard disk drives; except that nothing can be written to or changed on the CD. Using the proper software, a CD-RW drive module or DVD+CD-RW drive module can allow CD-RW discs to be used like a hard drive with writing, deleting, and editing capabilities. Vibration is normal for all high-speed CD-ROM drives due to unbalanced CDs or CD print. To decrease vibration, use the Notebook PC on an even surface and do not place labels on the CD. Listening to Audio CD The CD-ROM, CD-RW, and DVD-ROM drives can play audio CDs, but only the DVD-ROM drive can play DVD audio. Insert the audio CD and WindowsTM automatically opens an audio player and begins playing. Depending on the DVD audio disc and installed software, it may require that you open a DVD player to listen to DVD audio. You can adjust the volume through the volume control knob on the CD/ DVD-ROM drive face, function keys on the keypad, or by the WindowsTM speaker icon on the taskbar. 44 Using the Notebook PC Regional Playback Information Playback of DVD movie titles involves decoding MPEG2 video, digital AC3 audio and decryption of CSS protected content. CSS (sometimes called copy guard) is the name given to the content protection scheme adopted by the motion picture industry to satisfy a need to protect against unlawful content duplication. Although the design rules imposed on CSS licensors are many, one rule that is most relevant is playback restrictions on regionalized content. In order to facilitate geographically staggered movie releases, DVD video titles are released for specific geographic regions as defined in "Region Definitions" below. [. . . ] Some security products may also include a motion detector to sound an alarm when moved. LPT Port (Line Printer Port) Logical device name reserved by DOS for the computer parallel ports. Each LPT port is configured to use a different IRQ and address assignment. PCI Bus (Peripheral Component Interconnect Local Bus) PCI bus is a specification that defines a 32-bit data bus interface. PCI is a standard widely used by expansion card manufacturers. PC Cards (PCMCIA) PC cards are about the size of a few stacked credit cards and have a 68-pin connector at one end. The PC Card standard accommodates a number of function, communication, and data storage expansion options. [. . . ]
