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.
B.5.3Interactive Tests Menu
Interactive tests are diagnostics that need user interaction to complete.  Interactive
tests include:

·Video
 - tests the character sets, colors, monitor, and VGA

 - 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 control commands.  Printer test information is stored in printer test
files with an extension of .PDP.
