1-2 General Description
1.2Product Overview
The TravelMate 5000 Series Notebook Computers are high performance,
multimedia notebooks powered by the Intel P54-C Pentium
processor with built-in co-processor and dual, on-chip, 16KB data and
instruction caches. The 3-volt, Pentium chip, packaged in the TAB TCP
format, generates a 75 MHz clock processing rate. An off-chip, 256KB L2
cache buffer using asynchronous, 15 ns SRAM, is also implemented to
support the power of the Pentium. A simplified block diagram of the TM5000
Pentium Notebook is provided in Figure 1-2.
All members of the TM5000 family come standard with 8MB of 70-ns
page-interleaved, DRAM on the main board (expandable to 32MB with
user-installable RAM Expansion Boards based on 16M DRAM technology).
The Basic Input Output System (BIOS) firmware for the main system and
for the VGA BIOS is stored on a 256K x 8 Flash reprogrammable Flash
ROM. A Boot Block feature permits downloading of new BIOS changes
without having to physically replace the ROMs. Execution from ROM is
initially 8-bits wide but 32-bit performance is available when using the
Shadow ROM feature.
To take full advantage of the Pentium’s powerful multi-tasking capabilities,
the TM5000 series implements a 50MHZ, 64-bit high speed system bus that
interconnects the critical CPU, Memory and hard drive components. The
50-MHz system bus drives a 33 MHz, 32-bit, Peripheral Components
Interface (PCI) bus that supports the video subsystem, expansion
subsystem with other higher speed peripherals. The PCI bus also drives a
conventional 8MHz AT Bus for compatibility with AT peripherals (onboard
1.44MB floppy, keyboard, pointing device, etc.).
1.2.1MultiMedia Features
As standard features, the notebooks contain powerful audio and video
multimedia capabilities. A built-in SoundBlaster compatible sound board,
Jazz 16 Sound Software, plus internal speaker and microphone, and audio
input and output jacks give the notebooks a wide range of sound
capabilities.
The notebooks also offer powerful new video features on the PCI Expansion
Bus including the MotionVideo
storage and playback of video clips (320 x 240 clips can be played back at
30 fps with 24 bpp color quality). The notebook’s video controller has a
feature interface that is VESA VAFC compatible enabling a system to
provide live video overlay capability.
A control/data interface is also available on the PCI bus that allows an
implementation of NTSC/PAL (commercial TV) output required to display
graphics or video on standard TVs.

1.2.2Dual Intelligent Battery Packs
The TM5000 notebook series support the use of two hot plugable intelligent
battery packs (with front panel charge remaining indicators) that allow for
battery removal and replacement while the system is operational (as long as
one battery contains a partial charge). The notebooks use rechargeable
Lithium-Ion (Li-Ion) batteries. These battery packs are ejected from the
front of the notebook using battery eject switches located just above the
keyboard (See Figure 1-4).

1.2.3Standard Peripherals
As standard features, the TM5000 notebooks include a built-in 3.5 " Floppy
Drive and a user-replaceable, Hard Disk Drive. (Initially, either 810 Million
Byte drive or 524 million Byte Drive).
The hard drive uses the Fast IDE interface (with a 128 KB buffer) and has
an average access time of 12 milliseconds or less. The hard drive is
interfaced to the high speed, 64-bit, VL local bus for increased performance.
Additionally, the notebook includes two PCMCIA sockets and configuration
software that can accommodate additional plug and play PCMCIA devices.
