Note:

provided with this software).

- 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.

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.

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.

abled during memory testing. This assists in tracking down cache
timing issues.

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

•
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

•
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.
