3.4 Maximum and Minimum Levels of
POST
Two levels of POST are available, maximum (max) level and minimum (min) level.
The workstation initiates the selected level of POST based on the setting of
diag-level, an NVRAM variable.
Multiple CPU configurations combined with the amount of installed memory affects
the time required to complete POST. The following table lists the approximate
amount of time required to complete the POST. These approximate POST completion
times are based on 2.0 GB of DIMM memory installed with the diag-level
variable set to max or the diag-level variable set to min. The approximate POST
completion times also vary with the number of CPUs configured to the system.

The default setting for diag-level is max. Examples of the max-level POST output
on serial port A is provided in Section 3.4.1, "diag-level Variable Set to max" on
page 3-6". Examples of the min-level POST output on serial port A is provided in
Section 3.4.2, "diag-level Variable Set to min" on page 3-30.
