This may or may not be due to the fact that there is no >drive present at lun 0. I use an upgraded driver (there was sometime ago a posting for 1.1 on the net) with minix 1.5.10. There is no problem with accessing LUN 1 on scsi 0 when no drive is attached to LUN 0. Actually the drive connected to LUN 0 is dead, makes no difference if the drive is not connected or not powered up. The driver by the way fiddles around with some shift operations to determine the number of the adaptor... >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. I use this modified stwini.c because I could not access my harddisk on LUN 1 when LUN 0 was up and working, but I haven't traced down the problem, because applying diffs to the 1.5.0 stwini was easier. (as I work with real RCS now). Cheers Jan-Hinrich -- ~~~~ Jan-Hinrich Fessel, Universitaet Dortmund, IRB jf@unido.uni-dortmund.de atari-{sources,binaries}@unido.uni-dortmund.de
