  1. Open the drawing containing the blocks.
  2. Initiate the FIND command.
  3. Enter the value of the attribute.
  4. Choose the [Select Objects] button and select all the blocks.
  5. Choose the [Select All] button to select the matches.

Of course ToolPac users take this farther by specifying multiple fields to match and operators such as less than, greater than, etc.
