And they are the ones I would think you'd be least concerned about. This is basically just SCSI and IDE and floppy. We'll have converted all of the SCSI controlers that commonly appear on Alpha, and IDE and floppy are already done. I'd think the myriad of odd char devices and nics would be of more interest to you. r~
