ABSTRACT:
An adapter card which includes a non volatile memory for containing configuration parameters for establishing one of a plurality of configurations for the adapter card, as well as a pair of mapping bits which define the selected configuration. A default configuration is provided which places the adapter card in the legacy configuration during an initial system power up. The default mode also enables the adapter card to listen for a plug and play initialization key sequence, and switch the card configuration to a plug and play configuration. A companion utilities program permits access to the EEPROM for establishing a new set of configuration parameters in the EEPROM, and to change the mapping bits.
