the computer is powered up. In the event of a failure, the computer displays a descriptive
error message and issues a series of coded beeps (in case the display subsystem is not

memory tested, loads the Operating System and Windows environment.
1.4.2 PC-Doctor Diagnostics Program
The Extensa 900 Series Notebooks are shipped with PC-Doctor for Windows, a powerful
diagnostics tool that can help you scan a system for viruses, 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, 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.
Note: Refer to Troubleshooting Procedures (Section 5) for additional information
regarding the Diagnostics Program.
