The cable length >of the two cables combined might be a little over 1.5m The motherboard has only one bus on it. The termination settings for the controller should be "High Byte Termination Enabled", and "Low Byte Termination Disabled".

Active terminators may not be sufficient for the load you are putting on this system. -- Justin To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-scsi" in the body of the message
