Method and apparatus having a system BIOS write configuration data of a riser card to a controller configuration space when connecting the riser card to a motherboard

摘要

When a riser card is connected to a computer system motherboard, a storage device on the riser card will contain configuration data permitting the computer system to configure any peripheral device on the riser card. The configuration data will be treated by the BIOS in the computer system as a virtual add-on ROM thereby allowing it to execute and initialize any and all PCI configuration spaces associated with the riser card peripheral devices.
