Abstract
A data processing system such as a personal computer includes a plurality of expansion connectors for receiving adapter cards. A non-volatile memory stores programmable option select (POS) data that is stored when the system is configured. A Power On Self Test (POST) operation is performed during which adapters are checked to determine if any have been added, moved or removed, since a previous system configuration. If any have been so altered, the system may be placed in operation with all adapters enabled except for those which were altered.
