I am using XP pro. I do not have any Adaptec SCSI hardware. I tried using forceaspi, no luck. I tried installing the newest version, no luck. I have heard some people suggest installing a "fake" non-PNP SCI host like the 2940. But that is not supported under XP. Has anyone had luck installing ASPI on an XP system w/o SCSI. I don't have a working SCD anymore and want to play my games on an emulator.
