scsi.device in kickstart 3.2 for A2000 is for "gayle IDE", since same kickstart is also for A600 - so that one doesn’t work with A2091, I’m quite sure. So the question is if the A2091 scsi.device (2nd.scsi.device?) in the ROM is 3.2 compatible or not. It might even be worth it to try the scsi.device of the 3.2 kickstart for A3000 as that’s the same controller chip as on A2091.
