Planar Board Check
The planar board performs processing functions. Thus, the
planar board can cause processor problems. To verify the
problem, do the following:
1. Boot from the diagnostics diskette and start the PC
Doctor program (please refer to “Running the PC
Doctor Diagnostics Program” on page 29).
2. Run the System Board test to verify the symptom.
This test verifies both the planar board and the CPU
board.
If the tests detect a planar board problem, replace the
planar board.
Note: Don't touch the keyboard and pointing device when
the planar board (system board) test is running.
This may cause an unexpected error.
