Abstract
A computer system 10, such as a notebook computer, uses a modular bay 12 to receive optional devices 14. Buffer circuits 36 selectively isolate the device 14 in the modular bay from respective buses 34. An SMI handler, or similar executable routine, recognizes events which affect the modular bay 12 (such as insertion or removal of a device 14 from the modular bay 12), and performs the necessary routines to re-enumerate the system so that the device 14 is properly connected to its bus 34 and that the system software is aware of the hardware connected to computer 10.
