|
|
+ * This record allows software to correlate a Type 17 Memory Device Record
|
|
+ * with a specific DIMM (DIMM, Board, and/or Processor number if appropriate).
|
|
+ *
|
|
+ * There will be one Record Type 202 for each DIMM socket possible in the system.
|
|
+ * A system will include a record for each DIMM socket even if that DIMM socket
|
|
+ * is on a memory board which is not currently installed.
