– This interface serves as the control program for running both the IBM PC
Enhanced Memory Diagnostics and the suite of diagnostic tests provided by
PC-Doctor.
– The memory diagnostic tests determine which DIMM is defective and report
the socket where the failing DIMM is located. The Memory diagnostics can
run a quick and full test of the system.
