PC-Doctor Diagnostics
C.1 Introduction 
The Extensa Series Notebooks are shipped with PC-Doctor, 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 (by pressing F2
) or saved in a disk file (by
pressing F3
). 
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.
C.2 Starting PC-Doctor
PC-Doctor comes pre-installed on your Extensa Series Notebook Computer.
To run the utility, reboot your computer. 
The system continues the boot process and automatically displays the
PC-Doctor Diagnostics main menu.

							C.5 PC-Doctor Menus
There are several selections available from the menu bar of the PC-Doctor
Diagnostics main menu.  These include:
·?
·Diagnostics
·Interactive Tests
·Hardware Info
·Utility
·Quit
C.5.1 Online Help (?)
To obtain context sensitive help from any menu, press F1
.  Pressing F1
twice (or clicking on the question mark in the upper left-hand corner of the
menu) provides you with complete online documentation.
C.5.2 Diagnostics
The Diagnostics menu allows you to run non-destructive tests with little or
no operator interaction.  Options available from the PC-Doctor Diagnostics
Menu include:
·System Test - tests all major aspects of the system except those found
in Memory, Hard Disk, Floppy Disk, and the Miscellaneous Test
categories.
·Memory Test - tests all types of main memory in the system including
base, extended, expanded, and upper memory block (UMB) memory.
·Hard Disk Test - tests all hard disk drives in the system that are either
IDE or provide a BIOS command interface.
·Floppy Disk Test - tests all floppy disk drives in the system.
·All Tests - allows you to select which tests to run.  You can also specify
special testing options.  By pressing F2
, the following options are
available:
·Halt On Errors - interrupts testing if an error is detected.
n
Note:
  External serial and parallel port testing requires loopback plugs (not
provided with this software).
·External Loopback - tests external loopback of COM and LPT ports.
You can select the type of loopback adapter you want to use.
Diagnostics C-3 
						

							·Pass Count - selects how many times tests are repeated.  The highest
limit is 9999 times.
·Test Logging - opens the Log Options menu that lets you define how
test results are printed or stored to a file during testing.  By default,
PC-Doctor produces a test result file at the end of testing if an error
was detected.  
·Switch LCD - lets you change your video output to either the internal
LCD, external monitor, or simulscan mode.  If your system does not
support simulscan, both the external monitor and the built-in LCD
screen go blank.
·Cache Control - allows you to leave the level 1 and level 2 cache
enabled during memory testing.  This assists in tracking down cache
timing issues.  
C.5.3 Interactive Tests Menu
Interactive tests are diagnostics that need user interaction to complete.
Interactive tests include:
·Keyboard - tests the keyboard keys, LEDs, and repeat rate
·Video - tests the character sets, colors, monitor, and VGA
·Speaker - tests the volume response at different frequencies
·Mouse - tests the mouse driver, buttons, and functionality
·Joystick - calibrates the joystick and tests the buttons.  During the test,
the joystick(s) should first be calibrated.  To calibrate the joystick, move
the stick to the extremes in each direction.  PC-Doctor registers the
coordinate data and adjusts the screen display accordingly.
·Diskette Drive - checks diskette drive functionality
·Maximum System Load - burn-in tests a system.  This function
simulates the operating conditions that are produced by operating
systems such as OS/2 and Windows NT.  Some systems are not
compatible with the Maximum system Load test.
·Printer Test - tests for the correct acceptance and execution of common
printer control commands.  Printer test information is stored in printer
test files with an extension of .PDP.
·SCSI Test - PC-Doctor contains SCSI device testing features that work if
you have an ASPI or CAM device driver loaded.  You can select which
SCSI host adapter to work with if you have more than one SCSI adapter
present.  
·CD-ROM Test - tests CD-ROM drives using the Microsoft CD-ROM
Extensions (MSCDEX) and the standard CD-ROM device drivers.
