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.
– Pass Count - selects how many times tests are repeated. The high-
est 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 de-
fault, 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 inter-
nal 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 en-
abled during memory testing. This assists in tracking down cache
timing issues.

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.
