1.2 Product 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.

General Description 1-3
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.).
1.2.1 MultiMedia 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.

1.2.2 Dual 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).

1.2.3 Standard 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.
