To determine your processor feature code, type “WRKHDWRSC TYPE(*PRC)” on the command line of your AS/400. On the “Work with Processor Resources” screen, select option “7=Display resource detail” next to the first line which should have the text “Main Card Enclosure”. On the “Display Resource Detail” screen, you will find an entry for the “Processor feature code”. The model and serial number are also on this resource detail display.
