The acceptable values are:
0 (OFF) Do not reset
1 (ON) Reset the system
DIAG_LOE
If set, the diagnostic loops forever on a diagnostic failure. All output is
suppressed and the user must press the external HALT button to return to
console mode. This feature is available only with loadable diagnostics.
DIAG_QUICK
This environment variable determines the diagnostic test mode by
changing the way the startup diagnostics behave. When the DIAG_QUICK
environment variable is set to on, the system tests a subset of the normal
startup tests. The system enters the diagnostic test mode each time the
system is turned on.
The accepted values are:
ON Perform quick diagnostic tests.
OFF Perform normal diagnostic tests.
The default setting for the DIAG_QUICK environment variable is off, so that
normal diagnostic tests are performed at each system startup.
DIAG_SECTION
Set diagnostic operating environment to the specified value. The value is
reset to POWERUP each time the system is powered down. It is not saved
across power cycles. Table 56 lists diagnostic environment values.
Table 56 Diagnostic Environment Values
Value Description
0 - POWERUP Powerup operation. This value applies only when power is first applied
to the system.
1 - USER Customer mode of operation. This is the default condition each time
the system power is cycled on.
2 - FIELD Customer service mode. This sets up the diagnostic environment to
enable the customer service mode of operation. In this mode, special
loopbacks may be required to execute tests or utilities.
3 - MFG Enable manufacturing mode of operating. This mode requires special
loopback connectors as well as writeable medium. Some tests or
utilities may be destructible, and care must be exercised using this
mode of operation.
5 Reserved to Digital.

OFF.

/900 models or 10BaseT (300 models) only.
