RESIDENT NON-AUTOMATIC (RNA)
DIAGNOSTICS
The Resident Non-Automatic Diagnostics
(RNA) are contained in the system
electronics but do not run during BAT.
They are used when the diagnostics
cannot be loaded from the Diagnostic
Diskette. The RNA diagnostics aid in
isolating problems in the diskette
drive and intermittent system bus
failures. These diagnostic tests are
selected through the keyboard using
the Resident Non-Automatic Diagnostic
Flow chart in Figure 9-7.
A Resident Non-Automatic Diagnostic
Controller is located in the system
electronics to control the Resident
Non-Automatic Diagnostics. After the
RNA controller has been entered, the
test IDs appear one at a time on the
display. Pressing the MOVE key will
select the next test ID. The ID list
will loop from the last to the first
entry when the last test in the list
is being displayed and the MOVE key is
pres s ed. When the ENTER key is
pressed, the RNA controller will exe-
cute the selected test.
