You should be able to use both the 68-pin and 50-pin onboard SCSI connectors. You have to terminate the other ends of both chains. On some current motherboards there are actually three SCSI connectors: a 50-pin for slower narrow devices, a 68-pin for single-ended Ultra SCSI, and another 68-pin for LVD (low-voltage differential) Ultra2-SCI. In one of my machines I am using all three of them at the same time: an Ultra HD on one 68-pin connector, 2 Ultra2 HD's on the second 68-pin connector, and a Fast SCSI CDROM drive plus a Fast SCSI HD on the 50-pin connector. All internal. It works fine now. However, I discovered I had problems using certain 50-pin devices such as tape drives and CD burners in this setup, and had to move them to another SCSI adapter. It's weird, and is no doubt an Adaptec silicon bug or a motherboard bug somewhere. Regards, --QwikSand
