5.5 Fault Isolation Using Diagnostics
PC-Doctor, supplied with the Extensa Series Notebooks, is a powerful diagnostics tool
that can help you determine the hardware configuration of a local or remote system,
benchmark its performance, analyze the performance of all subsystems, and perform
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 or saved in a disk file.
5.5.1 PC-Doctor (In DOS Mode or DOS Windows)
Features of the diagnostic program are accessed through a series of pull-down menus
and basic keyboard keys (cursor keys to move highlighted pointer,
Enter
key to select
a highlighted feature,
Esc
key to cancel a function and move back one level.
PC-Doctor is typically user-friendly but if you don't understand a feature, context-
sensitive "help" information is available at any time by pressing the
F1
function key;
pressing the
F1
function key twice accesses the online Technical Reference Manual
for PC-Doctor.
A powerful set of utilities within PC-Doctor (that can be run locally or remotely)
simplify the task of determining system configuration data, allocating and using
system memory, IRQ and DMA use, what device drivers are installed, what COM and
LPT ports are assigned and what ports are available, identifying partitioning data for
fixed disk drive(s), determining the VGA setup information, reading the software
interrupts/interrupt vectors, etc.
Functionally, PC-Doctor includes the following:
♦
Group of non-Interactive diagnostic tests that perform a non-destructive test
of the major hardware functions in the notebook (Processor, Memory, System
board, video section, serial and parallel ports (when loopback adapters are
installed), hard disk drive and floppy disk drive).
♦
Group of Interactive tests (require operator input) for testing the keyboard, video
sections, sound subsystem, mouse, joystick, disk drive, printer subsystem and
the SCSI/CD-ROM Drive subsystems supported by the docking station options.
♦
Utility that provides detailed system information such as configuration data,
allocation and use of system memory, IRQ and DMA use, what device drivers
are installed, what COM and LPT ports are assigned and what ports are
available, partitioning data for fixed disk drive(s), VGA setup information,
software interrupts and interrupt vectors, and installed SCSI options.
