Acer Travelmate 5000 Maintenance Manual

1.5.2 Diagnostics Program
The TM5000 Series Notebooks are shipped with PC-Doctor, a powerful
diagnostics tool that determines the hardware configuration of a local or
remote system, benchmarks the system’s performance, analyzes the
performance of all subsystems, and performs a suite of interactive and
non-interactive tests on attached devices (such as printers, joystick devices,
VGA monitors, SCSI devices, CD-ROM drives). The test results are stored in
a log which can be printed out (by pressing F2) or...

1-30 General Description 

1.8.1 System Processor 
The System Processor function for the notebook is implemented on the Main
Board using  an Intel Pentium P54-C Superscalar Processor Chip. The
processor operates in conjunction with RAM and ROM Memory and other
control logic (E.G. the ACC2056 IC) to process software instructions (BIOS,
DOS, Windows, Applications).   
The processor communicates with hard disk and the memory components
using a high speed, VL-Local Bus.  All other high speed peripheral
components are driven by the...

1.8.3 I/O Subsystem
The I/O ASIC on the Main Board and an SMC 37C665 GT Combo I/O
Controller Chip control all AT-type I/O peripherals. Two cascaded DMA
controllers and two cascaded interrupt processors on the I/O ASIC support
transfers between memory and the 8-bit and 16-bit peripherals (via the
Combo Controller). The supported I/O interfaces include:
·Internal Hard Disk Drive Interface - Provides control information and
data exchange (via an integrated drive electronics (IDE)-type interface)
between the...

addition to powerful multi-media capabilities, the video controller offers full
hardware and BIOS compatibility with the IBM VGA standard.  
1.8.6 External VGA Capability
All members of the TM5000 notebook family provide a 15-pin, female,
D-type,  external VGA connector that can be connected to an external video
graphics adapter (VGA) type monitor.
Another feature of the notebook computer is the ability to provide both an
LCD display and simultaneously drive an external CR T (standard VGA
modes) with...
