I haven't been able to reach the drive if it is connected to scsi 0 lun 1. This may or may not be due to the fact that there is no drive present at lun 0. If someone can clarify the latter, I would be quite happy. I see no reason why two drives on two controllers will not work, provided that you set NR_DRIVES to the proper value (I assume 2 drives per controller), and that you jumper the controller properly. Also remember that if you use scsi 1 lun 0 that hd16 (that is major device 3 minor device 16) refers to the partition table of the drive, so you'll have to use hd17 to get the first partition of the drive. -- Frans Meulenbroeks (meulenbr@cst.philips.nl) Centre for Software Technology ( or try: ...!mcsun!phigate!prle!cst!meulenbr)
