Introduction
3-4 Service Manual
Begin the problem isolation at "Start of Call PIC 0010" on page 3-0010-1,
then carefully follow the steps to isolate the failure to a field-replaceable
unit.
The RT PC System Unit problem isolation procedures use the IBM RT PC
Diagnostic Diskettes and run tests from the ADVANCED DIAGNOSTIC
SELECTION menu. The diagnostic diskettes are stored in the Problem
Determination Guide.
Information about the tools required is in Appendix A.
