Abstract
Embodiments of the present invention provide detection, enumeration, and software configuration of optional choice of add-in cards types through a multiplexed bus interface. The PROM allows identification of the add-in device and software configuration to adapt to support it. In particular, plug and play detection of digital display codec devices and display and integration of software and firmware support for devices inside the add-in card are provided for.
Claims38
A method comprising:
- detecting whether an external card is used in a first graphics mode of a plurality of graphics modes available to the external card;
- detecting an identifier associated with the external card;
- and
- retrieving support components in response to the identifier including retrieving support components from serial presence detect memory in response to the external card having an identifier that does not correspond to one of a fixed list of identifiers.
A machine readable medium having stored therein a plurality of machine readable instructions executable by a processor, comprising:
- instructions to detect whether an external card is used in a first graphics mode of a plurality of graphics modes available to the external card;
- instructions to detect an identifier associated with the external card;
- and
- instructions to retrieve support components in response to the identifier including instructions to retrieve support components from serial presence detect memory in response to the external card having an identifier that does not correspond to one of a fixed list of identifiers.
An apparatus comprising:
- a non-volatile memory device containing support data;
- a communication bus for the memory device;
- and
- a controller to determine the support components for an external card operating in a first graphics mode of a plurality of graphics modes available to the external card, wherein the controller detects an identifier associated with the external card;
- and retrieves support components in response to the identifier including retrieving support components from serial presence detect memory in response to the external card having an identifier that does not correspond to one of a fixed list of identifiers.
A device comprising:
- a detector to determine the support components for an external card operating in a first graphics mode of a plurality of graphics modes available to the external card, wherein the detector detects an identifier associated with the external card and retrieves support components in response to the identifier including retrieving support components from serial presence detect memory in response to the external card having an identifier that does not correspond to one of a fixed list of identifiers.
