diag-level
max:
Operate power-on diagnosis in the maximum range. At this level, power-on
diagnosis takes extra start-up time; therefore, do not set diag-level to max
during normal operation.
min:
Operate normal power-on diagnosis (default setting).
off:
Do not perform power-on diagnosis. At this level, the system may be down
due to failed components. To prevent loss of data, do not set diag-level to
OFF.
