Here's an update for the archives so that others might benefit from the knowledge: I have a uVAX 3900 (KA655 CPU) with a KFQSA controller in it, the software didn't "see" it. I had heard that one of the switch settings controlled if the controller grabbed an address or not, so I flipped the switches (there are only 4) until I found it, the combination (1,2,4-off, 3-on) was successful. This vax boots to the chevron (>>>) prompt when the console control switch is set to the dot inside the circle icon. At the prompt two interesting commands are your friend. The first is which shows you the devices that the CPU sees. It will also identify those it recognizes. At first mine did not "see" the KFQSA, after flipping some switches it did, and then I could type: and it got into the DUP menu that had drive information. Now why DISK 1? Because DISK 0 is having problems. There is an ID jumper on the disk somewhere that tells the card what disk it thinks it is I believe. After getting into DUP I did ERASE and the DRVTST and both seemed to work so we're off to the races yet again... --Chuck
