Do you know if I can just get > an adapter cable for my external (non-wide) chain? Not sure, depends on if the aha2940W allows you to terminate just the upper 8 bits of the external bus. If it does allow that you can get a SCSI-III 68 pin to SCSI-II 50 pin cable and do this. If the board does not allow you to terminate the upper 8 bits your stuck. > do scsi devices on a second controller just show up as [r]sd7-[r]sd13?? By default they will show up at sd(n+1) where n is the last scsi disk on the first controller.

First one probed, depends on config file ordering. > where can I find documentation on /sbin/dset and the kernel -q option? There is no man pages for these, read the src :-(. -- Rod Grimes rgrimes@gndrsh.aac.dev.com Accurate Automation Company Reliable computers for FreeBSD
