The set simm_callout on command sets an internal environment
variable that enables code that isolates failing SIMMs during memory
testing. With this variable enabled, system self-test can take up to 40
seconds longer if a faulty SIMM is present.
The init command initializes the system and prints the console map.
This line in the console display notes that the SIMM callout
environment variable is on.
The show simm command requests a display of faulty SIMMS.
In Example 3-6, no faulty SIMMs were found.
The set simm callout off command turns off the environment
variable that enabled callout of faulty SIMMs.
The init command initializes the system in normal mode.
Example 3-7 shows a show simm command that calls out some failing SIMMs.
Section 5.1.5 tells how to locate, remove, and replace SIMMs in a memory
module.

The set simm_callout on and init commands are omitted here for
brevity.
The show simm command requests a display of faulty SIMMs.
SIMMS numbered J30 and J31 on the memory module in slot 7 are found
