ot even changing the device from scsi.device to cybppc.device, or the unit number from 1 (the default) to 3 (the scsi device number to which my CD ROM is set?)
Well, that's pretty obvious. :-) Although I do prefer to use the UNIT and DEVICE as tooltypes on the mountfile icon... But apart from these, nothing should change. Your host controller still thinks its connected to a 50pin device. Besides which there is no difference in control codes between 50 and 64. Your drive should automatically 'downgrade' itself to SCSI-2 (64 pin drives are usually SCSI-3 or UW). This is transparent.
How about HighCyl=11000 when other CD ROM mountlists use HighCyl=999? I thought that the CD itself didn't change when moved from a CD ROM drive on a Warpdrive SCSI bus, to a CD ROM drive on a CyberStorm SCSI bus.
These perameters make no sense for a CDROM, and any CD filesystem worth its salt will ignore them anyway. On my mountfile they are both set to 0.
