The Dell PERC S300 is a "SWRAID" product. It is correct that the hardware is an LSI1068e, but programmed with modified PCI IDs (all four a diffferent: vendor, device, sub-vendor, sub-device). The expansion ROM and drivers are from DotHill systems and are looking for these update IDs. The controller itself is running the IR/IT firmware with IR soft-disabled. To turn the controller back into a normal LSI1068e you would need to update the expansion ROM and the PCI IDs. As a science experiment you might be able to modify mpi(4) to look for the S300 IDs, but that would be an OS runtime only fix. -Jim
