Abstract
A device and method to enable a plug and play operating system to load the appropriate device for either a SCSI I/O device or a RAID adapter and direct interrupts from storage devices to the appropriate device driver. This device and method has a SCSI I/O device connected to several storage devices. The SCSI device can generate several interrupt signals and an identification selection signal. Further, this device and method has a PCI slot, to accept a RAID adapter, connected to the SCSI I/O device. The PCI slot can receive and generate several interrupt signals, as well as an interrupt disable signal, and an identification disable signal. Several tristate units are connected to the interrupt signals from the SCSI I/O device, the identification selection, the interrupt disable signal, and the identification disable signal. When a RAID adapter is plugged into the PCI slot, the tristate units route the interrupt signals from the SCSI I/O device to the PCI slot and disable the identification selection signal so that the plug and play operating system does not recognize the SCSI I/O device and does not load a device driver for it.
