Hi Rich, I think when you b st(controller LUN file) file the sun3 _automatically_ assumes st is at LUN 4. So, presuming your QIC tape is actually set at SCSI ID 4, you should boot it like 'b st' which defaults as 'b st(0,0,0)', with (0,4,0) being _implied_ (yes, I think it's weird too). Now INSTALL mentions that you may have to use the 'conv=osync' argument to dd if makeBootTape doesn't work. 'osync' is not in my linux man pages, however sync is. It allows one to pad a number of nulls defined by ibs per input block. Don't know if osync is different, however. Honestly, I just installed NetBSD on my Sun3x and I used the Netboot method, almost painlessly. I didn't fiddle with old, klunky, tapes, or a tape drive standard older than Rip Van Windkle (**cough**, on topic discussions here asside). I strongly suggest you Netboot the sucker. I found it a snap. Also, change the tape drive to SCSI 4, and then do a b st(0,0,0). Also, see: http://doener.unix-ag.uni-kl.de/install/install.phtml And dont forget your friend 'INSTALL' - helped me handle my first NetBSD install tremendously! Cheers, --jmg
