Bye, > Peter Czanik (maint@spike.fa.gau.hu) You want to wire down the devices. Look at the example in LINT. You'll need something like: controller scbus0 at aha0 controller scbus1 at ahc0 bus 0 disk sd0 at scbus0 target 0 disk sd1 at scbus1 target 0 -- Peter Dufault (dufault@hda.com) Realtime Machine Control and Simulation HD Associates, Inc.
