You need to do two things : # cd /dev # ./MAKDEV scd1 scd2 scd3 The second is that you need to fix the scd driver to deal with more than one drive. It mostly knows how to, but not properly : /* State machine copied from mcd.c */ /* This (and the code in mcd.c) will not work with more than one drive */ /* because there is only one mbxsave below. Should fix that some day. */ /* (mbxsave & state should probably be included in the scd_data struct and */ /* the unit number used as first argument to scd_doread().) /Micke */ Send some mail to micke@dynas.se if you want to talk about this with him. > I have asked this mailgroup several times in the last month and have only > gotten one response. It wasn't the answer unfortunately. I must admit I'd have thought you'd have at least _looked_ at the source 8( > - Jeffrey D.
